Preface

Aquatic mammals are important for balancing the biodiversity in the natural habitats. Nowadays, because of climate change, environmental fluctuations and human interventions most of the aquatic mammals in Bangladesh have been recognized as vulnerable throughout the river systems in the country, more especially in the Sundarban Reserve (SRF). Several organizations claimed this animals threatened, even thinking them to be extinct. Therefore, global diversity of dolphins is declining day by day. Sundarbans supports the last two remaining freshwater dolphins, the Endangered Ganges River Dolphin (Platanista gangetica), and the Vulnerable Irrawaddy Dolphin (Orcaella brevirostris). In this report, the author worked with different resource users and stakeholders and tried to find out the probable cause of challenging dolphin and fish biodiversity in the sanctuary areas in SRF. The possible causes for threatening dolphins including fishing activities into the meaningful boundary of cetacean sanctuary, aquatic pollution and climate change. Fry collection, aquafarm discharge, establishments and navigations are considered major causative agents for dramatic reduction of biodiversity, ultimately effect on the food chain of dolphins. The author unravel the gaps in the existing management policies of the government for protecting the aquatic biodiversity of sanctuary areas in Bangladesh Sundarbans and finding out the potential actions that shall be strengthen the existing management system. This guideline will be helpful for better conservation of the aquatic biodiversity in the sundarban sanctuary areas through strengthening biological and environmental support of aquatic organisms; and implementation of management policies.

Executive summary

Aquatic mammals are very sensitive and one of the good indicators of climate changes. Now a day due to climate change and anthropogenic activities these animals are being threatened and some are going to be extinct, therefore global diversity of mammals are declining day by day. Here in the contrast of Bangladesh these species are generally threatened with across their range. The possible causes for threatening dolphins include fishing activities, aquaculture into the meaningful boundary of cetacean sanctuary, aquatic pollution and climate change. Fry collection and over fishing in Sundarbans sanctuaries dramatically reduced the biodiversity, which affect on the food chain of dolphins. Additionally fishing net, dams and barrage construction on the migratory route restrict the movement of dolphins. In these circumstances this is the high time to take necessary initiation for the protection and conservation of cetacean’s species from extinct. Although many organizations around the world like IUCN, UNDP, AquaFish are continuously working on the protection and conservation of these aquatic and terrestrial organisms, and many regulations have been established on this issues. However, the problem is proper implementation of those regulations. Considering those problems the current research has been conducted with the aim to establish a biodiversity friendly guidelines on fisheries for the wildlife sanctuaries that will focus the level of fishing activities in the ecologically meaningful boundaries of cetaceans sanctuaries in sunderbans and also to find out the gap of policy implementation in fisheries management related to cetaceans, create alternative livelihood of coastal fisher communities as well as increasing awareness of the resource users in Sunderbans.

1 Introduction and overview

World’s largest tract of mangrove, the Sundarbans supports Asia’s last two remaining species of freshwater dolphins, the Endangered Ganges River Dolphin (Platanista gangetica), and the Vulnerable Irrawaddy Dolphin (Orcaella brevirostris). While these species are generally threatened with extinction across their range, both occur in the Sundarbans in populations large enough for early conservation interventions to be effective in ensuring their long-term survival. In 2012, the Government of Bangladesh declared three Dolphin Protected Areas comprising of six channels each with five km segments that support especially high densities of these two dolphin species. A few projects have also been implemented in the Sundarbans in the past for the sustainable management of cetacean ecosystem. In spite of the efforts and the existing legal, policy and institutional arrangements, the Sundarbans’ ecosystems in general and the three protected areas in particular are facing increasing threats due to over exploitation and unsustainable method harvesting resources associated to dolphin, poaching, unsustainable livelihood, industrial development, maritime traffic, unplanned tourism etc. In this backdrop UNDP Bangladesh in partnership with Bangladesh Government and with support from GEF is taking up the ‘Expanding the Protected Areas System to Incorporate Important Aquatic Ecosystems’ project to implement some long term solution and removing barriers to strengthen conservation management of the globally significant aquatic biodiversity of the Sundarbans taking into account development imperatives, need for sustaining livelihoods and retrogressive factors including climate change. The goal of this study was sustainable management of aquatic biodiversity in the Sundarbans through strengthening the fisheries management and conservation policies. The immediate objective of the project is to build capacity to effectively manage the existing protected areas established for dolphin conservation and also expand their operational coverage while still meeting the livelihood aspirations of local communities especially the fishers.

Specific objectives of the study:

1. To find out the level of fishing activities in the ecologically meaningful boundaries of cetaceans in Sundarbans sanctuaries. 2. Knowing livelihood adaptations of Sundarban resource users during environmental uncertainties or policy implementation. 3. To explore the gap of existing management and conservation policies, and finding shortfalls in applying the policies by different sectors.

4. Developing a guideline for strengthening existing fisheries regulations through stakeholders’ participation, and enhancing organizational capacity to effectively manage the existing protected areas established for dolphin conservation. 5. To increase awareness among the resource users on dolphin protection.

Habitat and ecology Dolphins usually live in small groups or alone. (Kasuya and Haque, 1972) found that 90% of the groups and 80.4% of total dolphins are seen during the dry season of Meghna and Jamuna Rivers of Bangladesh were solitary individuals. However, reports from the 19th century speaks of large school to seen near largest towns on the Ganges. (Reeves and Brownel, 1989)

The Irrawaddy dolphin thrives in tropical and subtropical waters of the Indo-Pacific region on and near shallow coastal waters. The countries where this species dwells are Vietnam, Cambodia, Singapore, Thailand, Indonesia, Burma, Laos, Philippines, Bangladesh, Brunei, India, and Malaysia. It inhabits coasts, rivers, estuaries, deltas and large lakes of its distribution zone, regularly near the . Almost all sightings have happened not more than 1.6 kilometers away from the coast and a less than 5 kilometers, and apparently, they do not usually live in deep waters (Dolphins-World, 2017)

Irrawaddy dolphins prefer coastal areas associated with the muddy, brackish waters at river mouths, ranging offshore as far as the extent of the freshwater plume often only a few km but more than 60 km at the mouth in Bangladesh (Smith et al., 2005). In rivers and mangrove channels, the species is most often observed at channel confluences and divergences and downstream of sharp meanders. They have been seen in the same area as finless porpoises in coastal waters of Bangladesh and Myanmar (Smith et al., 2005), and Ganges River dolphins in the waterways of the Sundarbans mangrove forest (Smith et al., 2006).

The Ganges River dolphin distribution is limited to the east of India. It inhabits the freshwater system Ganges-Brahmaputra-Megna (GBM) and the Karnaphuli-Sango river systems, and their tributaries, which run through Nepal, Bhutan, and Bangladesh. It inhabits large sections of these rivers or their tributaries from the tidal zone to the foothills of the Himalayas, the Cachar Hills (District of India) and the Garo Hills of Meghalaya (Indian state). During the flooding season, these dolphins leave the main canals and reach the temporary tributaries and flooded lowlands. It is most frequently found in bodies of countercurrent water located between the convergence of channels and meanders (pronounced curves) and occasionally go to channels and reservoirs. Their habitat has a depth of 3 to 9 meters, and water temperatures between 8 and 33 Celsius degrees (Dolphins-World, 2017).

Food and feeding Although it has visible teeth in the jaws, it does not use them to chew but to hold their prey firmly. Its eyes are not useful to find food because in the muddy waters of its habitat they are not required, that is, it is an functionally blind, so it uses echolocation to detect prey. This dolphin usually swims with a fin touching the riverbed to feel the sediments since animals hide there. Its snout is very useful for this. Once it finds a suitable prey, it holds the victim with the jaws and begins to swallow it whole starting from the head so that the scales (if the prey has them) do not hurt its throat. It does not always look for food at the riverbed. It’s most

16

common practice is finding a school of fish near the surface and drag them to the bottom to eat them (Dolphins-World, 2017).

Irrawaddy dolphins, feed on fishes, crustaceans, cephalopods, and fish eggs. Two species of cyprinid fish are thought to be important food sources for Irrawaddy dolphins found. Carp is the primary species consumed in other areas (Marinebio, 2018). It is a carnivorous cetacean that feeds on several species of cephalopods, fish, crustaceans and fish eggs. It establishes a strategy of cooperation in groups composed of 6-15 dolphins. To hunt, they can spit water to attract more fish and even hit large species with their lower jaw, perhaps in an attempt to play before eating. In some regions of Asia these dolphins fish in cooperation with local fishers which call them, and surprisingly the dolphins come swimming in semicircles and hauling the fish to the surface. Thus both parties benefit since the dolphins feed themselves with the fish stunned or trapped in the edges of the boat (Dolphins-World, 2017).

Ganges River dolphins are catholic feeders and feed on several species of fishes, invertebrates (Sinha et al., 1993), and possibly turtles and birds. They exhibit active foraging behavior in the morning (0700 hrs- 1000 hrs) and after noon (1500 hrs - 1700 hrs). These are some of their usual prey– Common carp, Gobio, Prawn, Freshwater sharks, Mahseer fish (Family Cyprinidae), Shrimp. The dolphins have been observed chasing and preying upon surface dwelling fish species, such as Rhinomugil corsula. On some occasions it was noticed that they drive fishes to a particular area for community feeding (Sinha et al., 1993)

Reproductive biology Irrawaddy- Individuals reach sexual maturity at around 3-9 years of age and the mating season is variable. For example, in the northern hemisphere dolphins mate from December to June and births occur between June and August. The female delivers one single offspring after a gestation period of 14 months. Researchers assume that, just as in other species, males mate with and compete for several females. At birth, the offspring weigh about 10 kilograms and measure about 1 meter. Six months later they are already able to consume fish, and after one year and a half, they are usually completely weaned (Dolphins-World, 2017).

Though the breeding season of the Gangetic dolphin extends from January to June, newly born calves can be seen even in other months. While mating usually takes place between March and June, it has been observed even in July (Harison, 1972). Only a single baby is born after a gestation period of about 9 months. At the time of birth, the neonate is about 70 cm and weighs about 4 kg - 5 kg. The mother and calf remain together for about one year. Maternal care is

17

presumed to be similar to that of other dolphin species, but in this case, after weaning (1 year after birth), the offspring do not maintain ties with its mother. The male attains sexual maturity at an age of about 10 years when they reach a length of 1.7 meters while the females are known to attain sexual maturity at 10 or less years (Kasuya, 1972) when they are around 2m long (Harison, 1972).

Distribution and Abundance

Irrawaddy Dolphins have a discontinuous distribution in coastal waters of the tropical and subtropical Indo-Pacific, and are predominantly associated with freshwater inputs (Stacey and Arnold, 1999; Smith, 2017). Coastal and estuarine populations occur from Borneo and the central islands of the Indonesian Archipelago north to Palawan, Philippines, and west to the , including the Gulf of Thailand. There are also freshwater subpopulations in three large rivers: Ayeyarwady in Myanmar (up to 1,400 km upstream from the river mouth), Mahakam in Indonesia (with a suspected current range between 90 km to 500 km upstream from the river mouth and the area of highest density between 180 and 280 km from the mouth), and Mekong in Cambodia and Lao People's Democratic Republic (a range of less than 200 km between Kampi pool, near Kratie, Cambodia, and Khone Falls, Laos, some 690 km from the river mouth). Within the extent of Irrawaddy Dolphin occurrence in these rivers, their area of occupancy is concentrated in deep pools associated with confluences and above and below rapids. Three other subpopulations inhabit marine-appended brackish water bodies: Chilika Lagoon in India, Songkhla Lagoon in Thailand, and Malampaya Sound in the Philippines. Although the map accompanying this assessment implies a continuous distribution throughout the coastal areas of the species’ range, subpopulations are known to be fragmented and patchily distributed, with long stretches of coastline where the species is now absent, either due to lack of freshwater inputs or likely local extirpation. For example, while Irrawaddy Dolphins are present in the coastal waters of the Trat Province, Thailand, they appear to be absent in the neighboring provinces of Chanthaburi and Rayong in the upper Gulf of Thailand (Hines et al., 2015). Similarly, while populations were documented in Kuching Bay and Similajau in Sarawak, Malaysia, the species was not observed during repeated cetacean surveys off the coast of Miri and the Baram River, where the species is known to have been present historically (Minton et al., 2011; Pilleri and Gihr, 1974).

Ganges Dolphin occurs in the Indus, GBM, and KS river systems of the South Asian subcontinent, from the deltas upstream to where movement is blocked by rocky barriers,

18

shallow water, fast currents, dams, or barrages (low, gated diversion dams). The linear extent of occurrence is now approximately 1,000 km (Braulik, 2006) and approximately 99% of the dolphin population occurs in only 690 km of river, which corresponds to an almost 80% reduction in effective linear range since the 1870s (Reeves, 1991).

The range of the Ganges subspecies (Ganges Dolphin) has declined progressively since the nineteenth century when it was mapped by Anderson (1879). Historically it occurred through several thousand kilometers of free-flowing river in India, Bangladesh, Nepal, and possibly Bhutan. The downstream effects of at least ten dams and barrages constructed in the Ganges main stem and tributaries have severely reduced and fragmented dolphin habitat (Smith and Reeves, 2000). Dolphins have undergone roughly a 100 km decline in their range in the Ganges River since the late 1800s, and disappeared from the upper Ganges between Haridwar and Bijnor, and Narora and Kanpur. Historically, they were found year-round in the Yamuna River approximately 400 km upstream to Delhi (Anderson, 1879), but in recent years, dolphins have not been reported in this river above the Chambal River confluence during the dry season because upstream channels have become too shallow and polluted to support dolphins (Sinha, 2000). In the northern Ganges tributaries, of the six dolphin subpopulations that were isolated above or between barrages, three have been extirpated (in the Gandak River above the Gandak Barrage, in the Sarda River above the upper and lower Sarda barrages and the Sone River) (Sinha et al., 2000) and one has been reduced to insignificant numbers (in the Kosi River above the Kosi Barrage) (Smith, 1993, Sinha and Kannan, 2014). A few Ganges Dolphins were still present during the mid-1990s as far downstream in the Hoogly River as Kakdwip (Sinha, 1997), and more recent surveys suggest their continued presence between Farraka and the Bay of Bengal in West Bengal, India (Chowdhury et al., 2016). The lack of adequate of water being released downstream of Farraka Barrage has eliminated dry-season habitat for more than 300 km, or until the Ganges (Padma)-Brahmaputra confluence in Bangladesh (Smith et al., 1998).

Occasional reports of dolphins in the reservoir behind (built in 1961) of the KS system occurred until the mid-1990s (Ahmed, 2000), but surveys in the late 1990s found no evidence that any Ganges Dolphins survive there (Smith et al., 2001). Thus, the dam's construction likely caused a substantial reduction in the subspecies’ range in southeastern Bangladesh, but the absence of any historical information on occurrence in the upper Karnaphuli makes any quantitative estimate of range reduction impossible Dolphins are expected to have been extirpated from the Subansiri River because of periodic dramatic

19

declines in river discharge from the newly completed Lower Subansiri hydroelectric project (Baruah et al., 2012).

Behavior Irrawaddy dolphins stay in groups of three to six individuals and are social within their pods. They are also social outside of their group and mixing between groups has been reported. When scouting areas, Irrawaddy dolphins raise their heads out of the water and rotate around to see their surroundings. Irrawaddy dolphins swim slowly and display sluggish movements. When they surface to take a breath, only the top of the head is visible and it is done quickly; only 14% of all surfacing between long dives include rolling, splashing, or limb waving and slapping. Before an Irrawaddy dolphin dives, it usually surfaces two times. The longest recorded dive is over six minutes long. Irrawaddy dolphins have also been seen waving or slapping their flippers and tail, breaching or partially leaping from the water, blowing bubbles, rolling sideways, and pausing at the surface. Water spitting has been observed on numerous occasions, but the reason for this behavior is unknown. Local fisherman report that they are able to identify individual dolphins based on unique behaviors. (Mammalian Species Orcaella brevirostris, 1999; Status and Conservation of Facultative Freshwater Cetaceans in Asia, 2002; Dawblin, 1972; Stacey and Leatherwood, 1997).

Ganges River dolphins swim and vocalize constantly. Due to the turbid nature of the Ganges, the underwater activities of Ganges dolphins in the wild are difficult to observe. Their short surfacing time is also a major constraint for behavioral studies. A recent study recorded six types of surfacing patterns, which were dependent on age-class and offshore distance of the individual (Sinha et al., 2010a). Ganges River dolphins exhibit greater preference for the surface than other river dolphins; even when swimming, which they do on their sides, they occasionally keep their beaks out of water. Newborn calves frequently leap completely out of the water.

The Ganges River dolphin is not usually considered to be gregarious. In one of the few quantitative studies of group size, it was observed that 90% of the groups and 80.4% of the total dolphins observed during the dry season in the Meghna and Jamuna Rivers of Bangladesh were solitary individuals. While the calves accompany mothers, adults are normally found alone or in small groups. However, other investigators reported groups of as many as 25 to 30 dolphins at the confluence of the Ganga and Gandak at Patna.

20

Biodiversity and Conservation Currently, the most immediate threat facing Irrawaddy dolphins is drowning in gill nets. The threat of gill net entanglement occurs primarily during the dry season (December to May), when dolphins settle in deep water pools. Dynamite and electric fishing occur in some important habitats. These activities are causing depletion of the dolphin's fish supply and noise from the explosions is potentially dangerous to dolphins. Due to the small population size and their narrow distribution, it is quite possible that dam construction anywhere within their habitat might critically endanger populations. Furthermore, uncontrolled tourism can harass dolphins in important habitats during the dry season and interfere with normal activities, such as feeding, resting, and socializing. Overfishing, collisions with boats and injuries from boat propellers are also threats to their survival. (Facultative river dolphins: conservation and social ecology of freshwater and coastal Irrawaddy dolphins in Indonesia, 2004; Status and Conservation of Facultative Freshwater Cetaceans in Asia, 2002).

Ganges River dolphins are among the most endangered of all cetaceans. With rising human populations in Southern Asia, the natural habitat of Ganges River dolphins has been extensively modified and degraded. Agricultural and industrial discharges are polluting the river systems in which these dolphins live and feed. In certain populations, the accumulation of heavy metals and organochlorides is posing serious health risks to the animals. In addition, dangerously high levels of arsenic in the water are a serious health threat to every animal using the water system, including Ganges River dolphins. Human modifications to river systems are also impacting the habitat of the dolphins. Over fifty dams affect populations of Ganges River dolphins, cutting populations off from one another. Dams have caused the gene pools of Ganges River dolphins to shrink, which could pose detrimental effects in future generations. Some engineering efforts are underway to construct channels around dams for aquatic wildlife, including dolphins. Ganges River dolphins are becoming more and more restricted to a smaller range. In Pakistan, a few hundred river dolphins are restricted to roughly 1200 square kilometers of water. Many local peoples regard these dolphins as a source of meat, oil and bait. Hunting has certainly impacted the numbers of dolphins in the Ganges and Indus river systems. Also, Ganges River dolphins are caught and drowned in fishing lines and nets, causing considerable fatalities. Bull sharks that make their way into South Asian river systems are known to attack waders and fishermen and are highly aggressive. Many of these attacks on local peoples are wrongly blamed on Ganges River dolphins. While it is highly unlikely these dolphins would ever attack

21

a human, their similar size and color to bull sharks results in their persecution by local peoples. (Kannan et al., 1993; Perrin et al., 2002; Reeves and Leatherwood, 1994).

2.1.2 Threats to Dolphin in Bangladesh Sundarbans

Habitat destruction Loss of whale and dolphin habitat is directly linked to increasing human activity in and along marine environments. Landfills, harbours, shipping channels, fisheries and aquaculture (fish farms) may all occupy or destroy areas that cetaceans need for feeding, resting and breeding. Recreational use of marine areas, including resort development and increased boat traffic, may drive away the whales, dolphins and porpoises that would normally use an area.

Habitat loss, particularly from dams in riverine populations, and degradation from declining or altered freshwater flows affecting estuarine populations, is a looming conservation threat with the potential for extirpating subpopulations and further fragmenting the already patchy distribution of the species (Kreb et al., 2010; Peter et al., 2016a; Thomas and Gulland, 2017).

Water development projects such as dams and irrigation barrages (diversion dams) have dramatically affected the habitat, abundance, and population structure of Ganges River Dolphins also throughout its range. Barrages and dams are physical barriers that isolate dolphins into small sections of river, fragmenting the population. In addition to fragmentation, dams and barrages have degraded downstream habitat and created impoundments with high sedimentation and altered assemblages of fish and invertebrate species. Canals branching from the river channels upstream of barrages represent population "sinks", as dolphins enter them with little or no prospect of safe return. Water diversion and use including intra- and inter-basin transfers, will continue to be driven principally by the escalating demands for water from agriculture, industry, and municipalities; by strategic considerations; and by the need to control flooding. Dolphin will probably continue to decline as subpopulations are extirpated due to habitat loss related to escalating water demands, large engineering structures (e.g., high dams, barrages, and embankments), and long-term climate changes (Smith et al., 2010; Chaudhary et al., 2012; Braulik et al., 2014).

2.1.3 Human intervention

Fishing Dolphins mostly live within a few miles of the coast and occasionally venture into some harbours, which can result in an overlap with commercial and amateur fisheries. Like whales,

22

dolphins are susceptible to entanglement in commercial fishing gear. Dolphins are caught accidentally in fishing nets in all areas where they have been studied (Smith et al., 2007). A significant number of dolphins have died through accidental entanglement in nets. Entanglement drowns dolphins when they are unable to reach the surface to breathe. A number of dolphin species are on the verge of extinction for this very reason.

Of 49 Irrawaddy Dolphin deaths recorded in Bangladesh from February 2007 to December 2016, two thirds were judged to be due to entanglement, mostly in gillnets, based on net and rope marks, entangled gear attached to the carcasses, and reports from fishermen (Thomas and Gulland, 2017). Mortality has also been recorded in drift gillnets targeting elasmobranchs in coastal waters of Bangladesh (Smith et al., 2008) and bottom-set gillnets targeting crabs in Malampaya Sound (Smith et al., 2004a). Fishermen in some areas report that dolphins are released if found still alive (Smith and Hobbs, 2002; Peter et al., 2016) but in the case of drowned animals, the oil may be used for medicinal purposes or the flesh eaten (Smith et al., 2004).

Mortality in fishing gear, especially gillnets, is a severe problem for Ganges Dolphins throughout most of their range and is an increasing problem for Indus Dolphins. They are particularly vulnerable because their preferred habitat is often in the same location as the fishing grounds (Kelkar et al., 2010).

Figure 1. Fishing activities in Sundarban areas near dolphin sanctuaries using banned nets (photo curtsey, Md. Modinul Ahsan). Scientific interactions Research on dolphins can potentially generate a threat to the dolphins themselves. This could include tagging (including satellite or other transmitters), taking biopsy samples, or through harassment. Permits and/or approvals are required to undertake research and will not be issued if the research presents undue risks to the dolphins.

23

Construction in marine areas Coastal works and development create noise, potentially masking sounds dolphins use for communication and navigation. They may also introduce pollution into the environment. These activities may displace the dolphins from important habitat and make it harder for dolphins to hunt and successfully produce offspring.

Figure 2. The forest fear: with the construction of a power plant in Rampal and the continued industrialisation in Mongla, the outskirts of the Sundarbans will lose its ecological balance, affecting the lives of humans, animals and plants dependent on the bounty of the forest and its surrounding (Proposed . Photo Courtesy: Bangladesh-India Friendship Power Company (Pvt.) Limited (BIFPCL)). Oil/gas drilling and mineral mining Seabed mining, drilling, and exploration, including seismic testing, is likely to have an impact on dolphins. Potential impacts include:

Discharge plumes and suspended sediments may interfere with marine organisms, as well as disturb the seafloor. This may impact dolphins by reducing or displacing the fish populations they rely on for food. Dolphins might also change movement patterns as a result. Seabed mining and seismic testing both introduce loud man-made noises into the marine environment. Loud noises may overpower the sounds dolphins use to communicate, navigate, and find food. Loud noises may disturb dolphins, causing them to be displaced from certain areas. Fish species may also be disturbed by noise and vessels, leading to a loss of food sources for dolphins.

24

Figure 3. Water of a small canal has turned into pitch black by the oil spilling from the sunken ship in the Sundarbans region Bangladesh, which endangered fish along with dolphin and other aquatic and terrestrial mammals (The Ecomonic Times, Dec 19 2014; The stream, Dec 12 2014). 2.1.4 Natural calamities and environmental changes Climate change has a multitude of effects on the oceans which is having an adverse impact on marine mammals such as dolphins and could become the biggest of all dolphin threats. As ocean temperatures rise from climate change, prey populations can be affected. Climate change also affects ocean currents altering prey distribution, feeding grounds, and migratory pathways.

The effect of Global Warming or seasonal weather changes has reduced their food sources, impacting the survival of dolphins in the wild. Extreme weather events have been a possible reason for the separation of calves from their mothers, resulting in the death of the calf. Increases in the frequency of extreme weather events are predicted due to climate change, which has the potential to adversely affect dolphins.

Other projected impacts of climate change include: reduction of available habitat for several cetacean species unable to move into colder waters (e.g. Ganges river dolphins); an increased susceptibility of cetaceans to diseases, like- a 2014 study of six Irrawaddy Dolphin populations in Malaysia, Bangladesh, and India found varying degrees of presence of cutaneous skin nodules, thought to be caused by a fibropapilloma. The progression of this disease may be associated with environmental pollutants (Van Bressem et al., 2014), and as such may be an indicator of habitat deterioration in the areas where it is detected. Climate change also reduces reproductive success, body condition and survival rates. Carbon dioxide is also dissolving into the oceans and making ocean waters more acidic which reduces the calcification of calcareous skeleton organisms like- Molluscs, crustaceans, corals and some phytoplankton; thus negative impacts on the food chain.

25

2.1.5 Freshwater flow and salinity fluctuations and gold, sand, and gravel mining are causing major changes to the geomorphic and hydraulic features of rivers and marine-appended lakes where Irrawaddy Dolphins occur (Smith et al., 2007). Increased sedimentation resulting from deforestation in surrounding watersheds has resulted in declining water depths. The accumulation of sediments led to shrinkage of the opening channel and a dramatic decline in salinity.

Embankments cause sediments to be deposited in the riverbed instead of on the floodplain, thereby eliminating or reducing the extent of the eddy counter-currents where dolphins are generally found (Smith et al., 1998). They also restrict access to floodplain habitat critical to the reproduction and growth of riverine fish species. Approximately 3,500 km of embankments have been constructed in the Ganges mainstem and the Gandak, Buri Gandak, Bagmati, Kamala, Yamuna, and Son tributaries (Mishra, 1999). Dolphins were apparently extirpated from at least 35 km of the Punpun tributary of the Ganges after embankments were constructed in 1975 (Sinha et al., 2000).

2.1.6 Pollution

Organochlorines Organochlorines are found in pesticides and some building materials, and reach dolphin habitat via coastal runoff. Organochlorines are known to affect the breeding success of some marine mammal species, in some cases resulting in sterility. They may also suppress their immune system. Organochlorine and butyltin concentrations in samples from the tissues of Ganges Dolphins were high enough to cause concern about effects (Kannan et al., 1993, 1994; Kannan, 1997, 2005; Senthilkumar et al., 1999). Pollutant loads can be expected to increase with industrialization and the spread of intensive agricultural practices. River Dolphins may be particularly vulnerable to industrial pollution because their habitat in counter-current pools downstream of confluences and sharp meanders often places them in close proximity to point sources in major urban

Metals Metals such as mercury, lead and cadmium, which have little or no recorded biological function, enter the environment through human activities. They don’t break down, and accumulate over time. These metals are often toxic even at low concentrations. Data on the effects of metal toxicity in cetacean species is sparse, and the risk from metal toxicity is unquantified for dolphins.

26

Oil spills The extraction and transportation of crude oil poses a potential threat for dolphins. Polycyclic aromatic hydrocarbons, such as those found in oil and gas, have been linked to cancers in some species of marine mammals. The risk from these compounds is unquantified for dolphin.

Plastic debris Marine mammals can become physically entangled in loops or openings of drifting plastic debris. Entangled animals may suffer impaired ability to catch food or avoid predators. They may also incur cuts, wounds and infections from the debris. Plastic ingestion could also pose a threat to the dolphins.

Pathogens Dolphins may be exposed to a range of pathogens that end up in the sea from farm run-off, through sewer outfalls or shipping, and through direct or indirect contact with other marine species. While there may be an anthropogenic source for some pathogens. Researches are required to better understand the impacts of these pathogens on dolphins and how any impacts can be avoided.

2.1.7 Degradation of fish biodiversity Modern fishing techniques are vastly more effective than those used one hundred years ago. As a result, many of the species that dolphins traditionally preyed upon have been dramatically reduced in their abundance and about one-third of all fishing stocks worldwide have collapsed like the sustained and heavy exploitation of small fishes of rivers by the wide spread use of the mosquito nets in river may affect the prey base of the Ganges River dolphin. In fact, overfishing has depleted fish populations to the point that in most of the world large scale commercial fishing is not economically viable without government assistance. The fall in fish stocks is a significant concern for humans too, but one that is not widely understood.

Shrinking tiger prawn population The natural abundance of tiger shrimp seeds is fast reaching the threshold limit. It is fast dwindling away from the natural waters of Sundarbans. The reasons too much over fishing at various stages of its life cycle. As its post larval stage in estuaries, it is trapped by fine push and drag nets and fine meshed bag nets (meen jal); the juveniles are trapped by bag nets (behundi jal) in estuaries; the juveniles and pre adults are caught in marine waters by large bag nets; the pre adults and adults by trammel nets. Even the spawns are not spared and are caught from the open seas by trawl nets. (Mahapatra et al., 1999)

27

Indiscriminate seed collection Collection of seeds (post larvae) of tiger shrimp (Panaeus monodon) and freshwater prawn (Macrobrachium rosenbergii) are one of the main sources of earning for the small and landless fisher man and women of this area. (De et al., 1978) found that 7-99 mm post larvae and juveniles were available throughout the year with peaks in June, July and December. This is the preferred species for brackish water aquaculture and a brisk seed trade has developed in the Sundarbans for post larval and early juvenile stages. During collection of economic prawn seeds, the rural people segregate the seeds and destroy other 90 to 95 % of fish and prawn seeds, which is leading towards the destruction of large number of estuarine species. A man- made catastrophe that destroys major parts of a fish community (species) will have importance relative to the fact that a large part of the human population of an area has had its protein source eliminated or reduced. These problems call for immediate steps to bring back a balance between the quantities of seeds produced in the nature and the quantity harvested shrimp and prawn. There is ban on shrimp post larvae (PL) collection from natural water body, but still PL catching is going on. It is necessary to implement the ban strictly with the cooperation department of fisheries, law enforcement agencies and coastal communities.

Poison Fishing Poison fishing is the one of the most primitive approach of catching fish in the many part of the world. Here in Sunderbans, fisherman sometime used different kinds of poisons in the river mouth or canal for catching fishes. Consequently huge amount of unwanted species i.e plankton, fishes, annelids, crustacean, mollusks are died that is directly effect on the food chain. And we know Dolphin is occupying in the top of the food chain, so the declining of those unwanted communities affecting the food chain of Dolphin. On the other hand poison intakes directly occur to the dolphin stomach during eating poison containing fishes and other aquatics poisoned organism.

2.1.8 Trophic structure/ food chain in Sundarbans ecosystem Mangrove habitat is one of the most productive ecosystems on Earth, lying between the land and the sea on tropical and subtropical coastlines (Kathiresan and Bingham, 2001; Kathiresan, 2002). Mangroves in the estuarine ecosystem play important roles in biodiversity and energy flow, and in maintaining functioning food chains, with phytoplankton playing a vital role as a primary producer. Phytoplankton initiates the marine food chain by serving as food to primary consumers such as zooplankton, shellfish, and finfish (Sridhar et al., 2006). In comparison to adjacent marine areas, larval retention and high productivity in mangrove-lined estuaries have

28

generally been attributed to the abundant planktonic food supply (Rajkumar et al., 2009). The distribution and abundance of commercially important fish and shellfish, and their larvae, are dependent on some species of phytoplankton as their main food source (Mitra et al., 2004).

The presence of primary food producers like phytoplankton and zooplankton had decreased sharply in the contaminated water. The food chain of aquatic species living in the world’s single largest mangrove forest, the Sundarbans, has been severely disrupted by the oil spill. The study report conducted by Khulna University (KU) said the presence of primary food producers like phytoplankton and zooplankton had decreased sharply in the contaminated water.

Figure 4. Fishing down the food web impact severely on the food community of dolphin and other predators (Pauly and Reg, 2009).

2.1.9 Disturbances: e.g. unplanned tourism, navigation, net barriers etc.

Interactions with boats and tourism Vessel traffic (for example, recreational boating or commercial vessels) can potentially disturb or strike dolphins. Although single encounters with a boat or a group of swimmers are unlikely to cause major disturbance for dolphin, the ongoing effects of multiple and extended encounters with dolphin watching operations could be harmful. Long-term effects of encounters may include reductions in breeding success, feeding activity, and resting opportunities. Eventually, dolphins may also leave certain areas to avoid disturbance.

Net and other Barriers Habitat loss and population fragmentation in several areas have resulted from the proliferation of fixed fishing gear. Like in the early 2000s, about 27,000 sitting traps and 13,000 barrier traps created more than 8,000 linear kilometres of barrier in multiple rows in the middle and southern

29

portions of Songkhla Lake. These fishing structures were left in place year-round and restricted dolphin movements such that their habitat was substantially reduced and the potential for demographic interaction with dolphins from the Gulf of Thailand was eliminated (Smith et al., 2004).

Obstacles on migratory routs Dams and barrages (low-gated diversion dams) restrict the movement of dolphins, rendering them isolated into separate sub-populations. The has affected the dolphin population in the Ganges, as the barrage has not only created a physical barrier for movement of the dolphin but also the reach of the river has been changed from a lotic to a lentic ecosystem (Sinha, 2000).

Figure 5. The main reason for the initial decline of the Indus river dolphin population was the construction of numerous dams and barrages that began in the 1930s. This construction split the population into small groups, degraded their habitat and impeded migration. Now the major threats include accidental capture in fishing nets, plus they are hunted for their meat, oil and for use in traditional medicines (WWF, 2001). 2.1.10 Management and conservation strategies for Dolphin sanctuaries

National and global existing management policies on Caetaceans Bangladesh has an extensive body of laws and policies for promoting conservation and the sustainable use of biodiversity and natural resources. Besides, the country also have signatory to several international conventions, treaties and multi-lateral agreements/ instruments related to environmental protection/natural resource management (UNDP, 2016). GOB (2010) reported some key international conventions and treaties signed/ratified by the country (Table 1).

There are a number of national policies, legislation and approaches taken by the government which provide provisions for biodiversity conservation and natural resources management in the country that have a bearing by the GEF project in the Sundarbans. Those policies are the: National Environment Policy, 1992; National Forest Policy, 1994; National Energy Policy, 1996; National Fisheries Development Policy, 1998; National Water Policy, 1999; National Agriculture Policy, 1999; Land Use Policy, 2001; Coastal Zone Policy, 2005; Bangladesh Wildlife (Preservation) (Amendment) Act, 2012; Bangladesh Forest Act, 1978 and subsequent amendments; Bangladesh Environment Conservation Act, 1995 and Environment Conservation Rules 1997; Playfield, Open Space, Park and Natural Water Reservoir Conservation Act, 2000; Flood Action Plan, 1990; Forestry Master Plan, 1996; National Biodiversity Strategy and Action Plan (NBSAP); National Conservation Strategy (NCS); National Environment Management Action Plan (NEMAP); and Sustainable Environment Management Programme (SEMP) (UNDP, 2016).

31

Diverse institutional arrangements have responsibilities to govern the natural resources in Bangladesh. The National Economic Council (NEC) is the highest policy making and programme/project approving institution in the country, which is headed by the Prime Minister. The Executive Committee of the National Economic Council (ECNEC), headed by the Finance Minister, reviews the plans and programmes sent by various ministries and endorse them (UNDP, 2016).

The project document of UNDP (2016) also reported that the Ministry of Environment and Forests (MoEF) is entrusted with the overall responsibility for the environment sector and the national focal point of all MEAs. The MoEF works with other ministries to ensure that environmental concerns are given due priority in their development programmes/projects. The implementing organs of MoEF are the Department of Environment (DOE) and the Forest Department (FD). While the DOE has wide ranging responsibilities from enforcement of environmental laws and codes in addition to conducting Environmental Impact Assessments (EIAs) of public and private sector projects, the FD is a specialized body of the MoEF dealing with the management of forest reserves, wildlife and protected areas. The Forest Department works towards ensuring natural sustainability and biodiversity conservation through social forestry, , , , protected area management etc. It is one of the oldest departments of the Government.

Beside above organizations, other ministries/departments/agencies including the Ministry of Land, Ministry of Water Resources, Ministry of Industries, Ministry of Power, Ministry of Energy & Mineral Resources, Ministry of Fisheries & Livestock, Bangladesh Planning Commission, Disaster Management Bureau, Bangladesh Water Development Board, Water Resources Planning Organization, Bangladesh Meteorological Department, Ministry of Agriculture, Department of Agricultural Extension, National Agricultural Research System of Bangladesh, Navy, Coast Guard and Port Authority have defined mandates and jurisdiction over matters concerning aquatic resources (UNDP, 2016).

Many research institutions like the Bangladesh Forest Research Institute (BFRI), Bangladesh National Herbarium (BNH), Bangladesh Agricultural Research Institute (BARI), Bangladesh Rice Research Institute (BRRI), Bangladesh Livestock Research Institute (BLRI), and many university departments are conducting research and implementing programmes on biodiversity and natural resource management. Similarly, various training institutions including the Bangladesh Public Administration Training Centre (BPATC), National Academy for

32

Educational Management (NAEM), National Academy for Planning and Development(NAPD), Forest Academy (FA), Bangladesh Space Research and Remote Sensing Organization (SPARRSO), Institute of Water Modelling (IWM) etc. are also involved with overall environmental management and cross-cutting environmental issues (UNDP, 2016).

The District Administration is headed by the Deputy Commissioner, and includes functionaries responsible for different aspects of district governance. Of note to this project are functionaries responsible for district planning, fisheries, agriculture, forests, tourism, wildlife etc. Related to this is the presence of the local government including the elected members of the Zillas, Upazillas and Union Parishads, which is highly relevant in the context of the project. At the village level, there are also several Community Institutions (CIs) that are supported by the government as well as non-governmental organizations. These are also community or user- group based organizations such as Self Help Groups (SHGs), Women’s Groups, Fishermen’s Associations, tour operator groups, Youth Groups, Co-Management Committees (CMCs), Village Forum (VFs) etc. (UNDP, 2016).

A large number of Civil Society Organizations (CSOs) and Non-Governmental Organizations (NGOs) – both conservation-focused and social service groups are engaged in implementing various programmes on biodiversity conservation, social development and addressing policy issues. These organizations include Centre for Policy Dialogue (CPD), Centre for Nature Resources Studies (CNRS), Centre for Advanced Research in Natural Resources & Management (CARINAM), Nature Conservation Management (NACOM), Bangladesh Centre for Advanced Studies (BCAS), Poribesh Bachao Andolon (POBA), Bangladesh Poribesh Andolon (BAPA), WildTeam, Sushilan, Association for Social Advancement (ASA), PROSHIKA, Wildlife Conservation Society (WCS), International Union for Conservation of Nature (IUCN) etc. (UNDP, 2016).

3 Situation analysis

3.1 Context

3.1.1 National context The People’s Republic of Bangladesh, nestled between the Indo-Himalayas and Indo-Chinese sub-regions (between 20° and 27° N and 88° and 93° E), is the farthest downstream alluvial zone of three major river systems of the Himalayan Range – the Ganges, the Brahmaputra, and the Meghna. The total geographical area of the country is 147,570 km2, of which about 80% is comprised of one of the world’s largest deltas (floodplains and wetlands networked over 300 rivers) bordered by India in the West, North and Northeast; by Myanmar in the Southeast and by the Bay of Bengal in the South (GoB, 2010).

Bangladesh has been reported as the highest densely populated (1,015/km2) country in the world with the total population of more than 160 million (BBS, 2011). Although fertility rates have declined in recent years, at the current growth rate (1.34% per annum), the population is projected to reach 220 million by 2040 (BBS, 2011). Around 75% of the population is rural and a significant proportion (around 35 million or 22%) lives along the 710 km long coastal belt (World Bank, 2010a; PDO-ICZMP, 2004).

Notwithstanding the notable strides made in economic and social development in recent decades, Bangladesh is still among the Least Developed Countries (LDCs) (UNDP, 2013). In the Human Development Index, it ranked 146 (out of 187 countries) in 2012 (UNDP, 2013). During 2012-13, the Per Capita Gross National Income (GNI) was calculated as $923 whereas the Per Capita Net National Income (NNI) stood at $859 (BBS, 2010; World Bank, 2013). An estimated 50 million people still live in poverty, including almost 18% living under extreme poverty (BBS, 2010a). Despite these challenges, the net primary-school enrollment has reached 94.7% and under-five childhood mortality has declined by 58% from 133 to 56 per 1,000 live birth in 1989-1993 and 2005-2009, and the country is on track to meet its United Nations Millennium Development Goals of 48 under-five deaths per 1,000 live births by 2015. Similarly, infant mortality rate has declined by 48% from 87 to 45 per 1,000 births over the same time period (NIPORT, 2012). However, more than two-thirds of the rural population is landless or effectively landless (i.e. own less than 0.2 ha land). More than half of the country’s population directly depends on natural resources for survival and well-being (UNDP, 2016).

37

Bangladesh remains a predominantly agrarian economy with agriculture occupying nearly 76% of the total land area of the country. Other important economic activities related to land/water use and food production include fisheries, aquaculture, and salt production. Over 60 million people depend on aquatic resources with an estimated one million working as full-time fishers and another 11 million engaged in part-time fishing. The latter are especially significant for the nutritional security of the poor (UNDP, 2016). While agriculture employs the largest proportion of the labour force (around 47.3%) (BBS, 2010b), its proportional contribution to GDP has been falling. During 2012-13, the combined share of agriculture and forestry sector stood at 14.3% of GDP (at constant prices) and 13.7% (at current prices). The fisheries sector is estimated to employ around 5% of the workforce and contributed some 3.6% of GDP (at current prices) in 2012-13 (UNDP, 2016). Service sector and Industrial sector contribute around 50% and 30% respectively to the country’s GDP (UNDP, 2016). Foreign remittances and the export-led garment industry have been the dual engines of the national economy in recent times (UNDP, 2016).

Annual consumption of fish in Bangladesh is 11.9 kg per capita (in 2010), accounting for 11.1% of total protein consumption. Altogether, some 76% of the fish consumed are inland species and 18% marine. Urban annual consumption stands at 14.5 kg/capita and rural consumption at 11.0 kg per capita per year, with rural communities eating a larger percentage of inland fish (70%) than urban communities (61%). The most commonly consumed freshwater species include tilapia, catfish and mrigal carp. Hilsa shad is the most commonly consumed marine species and is a valued commodity for export (FAO, 2014).

One of the most disaster-prone nations in the world, Bangladesh experiences frequent, extreme & erratic weather events and storms that cause wide-spread economic, ecological, and social damage (UNDP, 2016). For instance, of the 250,000 deaths reported worldwide due to cyclones between 1980 and 2000, around 60% occurred in Bangladesh (World Bank, 2010a). In the past 200 years, the country experienced at least 70 major cyclones, of which 40 have occurred since 1948 (UNDP, 2016). Floods are major recurring phenomena that affect around 30-50% of the country each year. Around 93 major disasters were recorded between 1991 and 2000 that caused nearly 200,000 deaths and a direct economic loss of approximately US$ 5.9 billion or around 0.5 – 1% of the country’s annual GDP. Women bear a disproportional brunt of such natural disasters (World Bank, 2010b).

3.1.2 Climate and geographic context Bangladesh has a mostly subtropical climate with four pronounced seasons - a hot humid monsoon (June to September); a progressively cooler, drier season (October to November); a cool dry winter (December to February); and a progressively hotter and drier summer (March to May). The average annual temperature varies between 18 and 29°C, with a maximum summer temperature of about 41°C, and winter temperature between 10°C and 20°C. Average annual rainfall ranges from about 1,400 mm to 4,400 mm, with 80% occurring during the monsoon (UNDP, 2014).

Dynamic physiographic, climatic, and hydrologic conditions shape the alluvial delta of Bangladesh as well as the rich biodiversity it supports. This bounty of nature is exemplified by the country’s diverse ecosystems ranging from the mangrove forests of the Sundarbans in the southwest; coastal and marine ecosystems in the far south; deep natural water basins called “haors” and “baors” in the northeast; arid areas in the upper mid-section; hill tracts in the southeast; and flat sandy or marshy deltas of the large rivers of the middle of the country extending south (MoEF, 2010). The country has 29 agro-ecological zones (GOB, 2010) and twenty five bio-ecological zones (UNDP, 2016). Although some 2.56 million ha or 17.8% of the country’s total area is classified as forests, only around 11% is actually under cover (ADB, 1995; UNDP, 2016). Another 20% is classified as ‘other wooded land’, which includes within homesteads and other agricultural tree crops (FAO, 2010). had declined by more than 90% over the past 100 years and per capita forest cover in Bangladesh is amongst the lowest in Asia (UNDP, 2016).

3.1.3 Biodiversity significance Bangladesh is home to over 125 globally threatened species (IUCN Red List) – including 21 Critically Endangered, 34 Endangered and 69 Vulnerable species. It supports Asia’s last two

39

remaining species of freshwater dolphins - the Endangered Ganges River Dolphin (Platanista gangetica), an obligate freshwater cetacean of the South Asian subcontinent; and the Vulnerable Irrawaddy Dolphin (Orcaella brevirostris), a facultative freshwater cetacean found in the estuaries and some large rivers of the Indo-Pacific (UNDP, 2016). The country has established a national system of protected areas to conserve some of its most significant biodiversity. It has, so far, designated 36 protected areas comprising approximately of 2,654 km2 or about 1.8% of the country’s geographical area. These protected areas (corresponding to Category IV of the IUCN Protected Area classification) cover around 11% of the area under the control of the Forest Department (UNDP, 2016).

Bangladesh’s diversity of aquatic ecosystems includes Haors (seasonal wetlands that are formed in large depressions appended to rivers when discharge is high), mangrove forests, freshwater swamp forests, oxbow lakes, rivers, shallow coastal seas and a deep (900m+) submarine canyon called the Swatch-of-No-Ground. Natural mangroves cover an estimated 584,000 ha (representing 39.2% of all classified state-owned forest land) and mangrove around 137,080 ha (UNDP, 2016). The Sundarbans, situated in the southwest of Bangladesh and shared with India, is the world's largest continuous mangrove forests, and it is listed as one of WWF’s Global 200 Eco-regions (UNDP, 2016). Around 62% of the Sundarbans are in Bangladesh and the rest in India. The total area of the Sundarbans in Bangladesh is 6, 01,700 ha of which 411,230 ha is covered by forests; the rest is under water (although this is variable according to seasonal discharge) in the form of rivers and creeks (UNDP, 2016).

The Sundarbans Reserved Forests (SRF) is one of the two RAMSAR sites in the country. Each year about 2.4 billion tons of sediments are transported through the Sundarbans, resulting in dynamic land accretion and erosion processes (Poffenberger, 2000). This in turn creates a complex mosaic of geomorphic, bathymetric and hydraulic features, which support high levels of terrestrial and aquatic biodiversity. Recognizing the global biological significance of the area, in 1997, UNESCO declared the three Wildlife Sanctuaries in the far southern portion of the Sundarbans viz., Sundarbans West (715 km2), Sundarbans South (370 km2), and Sundarbans East (310 km2), covering 139,700 ha, as a ‘World Heritage Site’. Together these sanctuaries encompass about 23% of the Reserved Forest (UNDP, 2016).

Waterways of the Sundarbans are the only place where both the Ganges River and the Irrawaddy dolphins, occur together. While these species are generally threatened with

40

extinction across their range, both occur in the Sundarbans in populations large enough for early conservation interventions to be effective in ensuring their long-term survival. Based on an intensive monitoring programme carried out over three years by the Wildlife Conservation Society (WCS), six five km channel segments that support especially high densities of these two dolphin species were selected as priority habitats or ‘dolphin hotspots’ (Smith et al., 2009). In 2012, the Government of Bangladesh notified these ‘dolphin hotspots’ as three Wildlife Sanctuaries {viz., Chandpai (including three hotspots), Dhangmari (including two hotspots) and Dudhmukhi (including one hotspot)}. These sanctuaries intend to provide safe havens for freshwater dolphins in 31.4 linear km of channels with a total area of 10.7 km2 (UNDP, 2016). The focus of the present study is to develop a sectoral guideline by improving the management effectiveness of these aquatic protected areas though a collaborative approach.

3.1.4 Ecological and biodiversity context of the Sundarbans The Sundarbans, the world’s largest continuous tract of mangroves, is composed of vegetated low-lying islands, with elevation ranging from 0.9-2.1 m above mean sea level, interspersed with a maze of tidal waterways from a few meters to a few kilometers wide (Katebi and Habib, 1989; Iftekhar and Islam, 2004). Even though, the ecological history of the Sundarbans is yet to be understood in detail, it is known to be of relatively recent origin, and the extent of its coverage has changed considerably since its formation. There are three broadly defined ecological zones in the Sundarbans: a) low saline zone; b) the moderately saline zone; and c) the strongly saline zone (Figure 1) (Aziz and Paul, 2015). These zones are based on the complex interplay of factors such as spatially and temporally variable fresh-water flow, micro-climate, hydrology, edaphic factors, local rainfall, tidal flows, humidity, geographic aspect, sunshine etc. The zones are affected by daily changes in tidal flux, seasonal changes in hydrology and climate, and long-term degradation due to human impacts including the construction of upstream dams, alterations in the watersheds and sea-level rise (MoEF, 2010).

41

Figure 7. (A) Three saline zones of BSMF in 1983 (Chaffey et al., 1985) but divided in to two zones with approximate Curtis demarcation in 1930’s, by a dotted line (Curtis, 1933); (B) A largely different distribution pattern of the three zones was found after about 10 years (Siddiqi, 1994); (C) Seasonal variation of salinity in the Passur River water (at Mongla) and surface soil of Sarankhola, Chandpai and Satkhira ranges in the late 1980s (Hassan et al., 1990). Dynamic erosion and accretion processes, which determine the physiographic character of the Sundarbans, are buffered by the relative stability provided by the mangrove forests (Smith and Mansur, 2012). These changes are further driven/shaped by a complex interaction of sea-level changes, sedimentation and neo-tectonic subsidence (Barlow, 2008). Together these have profoundly influenced the ecological processes, and the flora and fauna (both relict as well as nascent) in the Sundarbans. Sculptured through the ecological landscape of the Sundarbans are large human populations in fringe villages who depend on the forests and waterways for vital ecological services, and meeting subsistence and livelihoods needs (MoEF, 2010).

Some of the key ecosystem goods and service functions (both tangible and intangible) provisioned by the Sundarbans, which are highly relevant at local, regional and global scales, inter alia include: (1) entrapping sediment and land formation; (2) coastal protection against wave action and wind erosion; (3) protection of human lives and habitation from frequent & extreme storms and cyclones; (4) shelter and habitat for diverse life-forms; (5) nursery for fish and other aquatic life; (6) supplying oxygen; (7) nutrient cycling; (8) timber and small timber production; (9) supply of food, NTFPs and building materials; (10) carbon storage, sequestration and cycling; (11) opportunities for education, scientific research, recreation and ecotourism; and (12) act as vital migration corridor for anadromous species such the highly valued hilsha shade (UNDP, 2016). The Sundarbans also represents the largest single carbon sink in the country (MoEF, 2010).

42

3.1.4.1 Faunal and floral diversity According to various records, the Sundarbans supports around 49 species of mammals, 59 species of reptiles, eight species of amphibians, 400 species of fishes and 315 species of birds. As many as 20 globally threatened species inhabit the Sundarbans. Historical records suggest the loss in recent times of at least six large mammal species from the Sundarbans viz., Javanese rhinoceros (Rhinoceros sondaicus), one horned rhinoceros (Rhinoceros unicornis), wild buffalo (Bulbulus bulbulus), gaur (Bos gaurus), swamp deer (Cervus duvaucali) and the hog deer (Axis porcinus) (MoEF, 2010). Aquatic ecosystems of the Sundarbans also support a significant number of globally important species – including IUCN Red List globally Critically Endangered and Vulnerable species (UNDP, 2015).

Some of the Critically Endangered species found in the aquatic environs of the Sundarbans include the knifetooth (Anoxypristis cuspidate), imperial heron (Ardea insignis), River terrapin (Batagur baska), freshwater sawfish ( pristis, may be regionally extinct) and possibly the Ganges River shark (Glyphis gangeticus). Endangered species dependent on the aquatic ecosystems include the Asian masked finfoot (Heliopais personatus), Cantor's giant soft-shell turtle (Pelochelys cantorii), Northern River Terrapin (Batagur baska), fishing cat (Prionailurus viverrinus) and as noted above the Ganges River dolphin (UNDP, 2016).

The Sundarbans also supports a great diversity of terrestrial mammals (49 species) (Gopal and Chauhan, 2006). It is a well-known habitat of the Royal (Panthera tigris), with one of the world’s largest surviving population estimated between 350 and 500 individuals (Ahmad et al., 2009). Other carnivores include the leopard cat (Prionailurus bengalensis), fishing cat (Prionailurus viverrinus), jungle cat (Felis chaus), small-clawed otter (Aonyx cineria – both terrestrial and aquatic) and jackals (Canis aureus) (Barlow, 2008). The main ungulates are spotted deer (Axis axis), wild boar (Sus scrofa), and barking deer (Muntiacus muntjak). Rhesus macaque (Macaca mulatta) is the only non-human primate present (UNDP, 2016).

Another hallmark of rivers and near-shore waters of the Sundarbans is the presence of a diverse cetacean community. Ganges River dolphins and Irrawaddy dolphins are commonly found in the waterways of the forests whereas Indo-Pacific hump-backed dolphins (Sousa chinensis) and finless porpoises (Neophocaena phocaenoides) are occasional visitors (Ministry of Environment and Forests, 2010). The most frequently sighted reptiles are monitor lizard (Varanus salvator) and estuarine crocodile (Crocodylus porosus). Less often seen are various snakes including the dog-faced water snake (Cerberus rynchops), red-tail pit viper

43

(Cyptelytrops erythrusus), king cobra (Ophiophagus hannah), Indian spectacled cobra (Naja naja), and the Indian python (Python molurus). Nine species of turtles have also been recorded in the Sundarbans including two marine turtles (Rashid and Swingland, 1997).

Around 400 species of fish, whose distribution is highly dependent on salinity gradients, have been catalogued in the Sundarbans. Crustaceans, such as crab, shrimp, prawns and lobster, comprise a substantial proportion of the overall aquatic (Islam and Haque, 2004). Among a diverse array of terrestrial invertebrates, the giant honey bee (Apis dorsata) is of particular economic importance and represents an important livelihood component of the local communities of the Sundarbans (Gopal and Chauhan, 2006). The coast of the Sundarbans is a breeding ground for threatened marine turtles including the Olive Ridley turtle (Lepidochelys olivacea) and Green turtle (Chelonia mydas). A total of 145 fish and 33 crustacean species were recorded during ecological investigations of freshwater dolphin hotspot and non-hotspot segments in 2010. Among these fishes, 67 were found in both hotspot and non-hotspot segments, 46 were found only in hotspots and 32 were found only in non-hotspot segments. Among the crustacean species, 23 were found in both segment types, whereas seven were found only in hotspots and three were found only in non-hotspot segments (WCS/BCDP, 2014).

As the largest forests in the country, and with extensive aquatic and marine components, the SRF represents a significant storehouse of floral biodiversity. In late 1990s, it was reported that 245 genera and 334 species of plants are present in Sundarban Reserve Forest (SRF) (IFMP, 1998). The Sundarbans flora has an abundance of Heritiera fomes, Excoecaria agallocha, Ceriops decandra, Sonneratia apetala and Nypa fruticans. While most mangroves in other parts of the world are characterized by members of the Families Rhizophoraceae, Avicenneaceae or Laganculariaceae, those of Bangladesh are dominated by Sterculiaceae and Euphorbiaceae (UNDP, 2016). A survey conducted by IUCN Bangladesh in 2003 listed 108 non-tree plant species including 17 orchids, 21 fern and fern allies, six algae and 16 lichens in the Sundarbans. Of the reported 66 species of “mangroves” in the SRF, 25 have been identified as ‘true mangroves’, while the others are considered as ‘mangrove associates’ (Siddiqi, 2001).

3.1.4.2 Status and distribution of Ganges River and Irrawaddy dolphins in Sundarbans The Sundarbans is the only environment that supports the Endangered Ganges River dolphin and Vulnerable Irrawaddy dolphin, the last two remaining species of freshwater dolphins in Asia (UNDP, 2016). In 2002, the population of Ganges and Irrawaddy Dolphins in the Bangladesh portion of the Sundarbans was estimated to be around 225 and 451 individuals respectively (Smith et al., 2006). The density of Ganges River dolphin is particularly high in

44

the low-salinity eastern portion of the mangrove forests with greater concentrations found at channel confluences. The density of Irrawaddy dolphins is high in the high-salinity western portion but the range of both species overlaps in the eastern side. At a waterscape scale, both Ganges River and Irrawaddy dolphins prefer low salinity waters. However, both species also partition themselves such that Ganges River dolphins generally occupy the northeastern portion (which receives freshwater input from the Ganges River), while Irrawaddy dolphins generally occupy the southwestern part with more salinity (Smith et al., 2009).

According to a series of surveys conducted in 2011-12, the highest density of Ganges River dolphins was found in the Dhangmari wildlife sanctuary during the pre-monsoon and the lowest density was found in the Dudhmukhi wildlife sanctuary during winter/dry seasons. Ganges River dolphin calves were found in the Chandpai wildlife sanctuary during all seasons; in the Dhangmari wildlife sanctuary during the dry, pre-monsoon and monsoon; and in the Dudhmukhi wildlife sanctuary during the pre-monsoon and monsoon seasons. In all three sanctuaries, Irrawaddy dolphins were observed much less frequently compared to Ganges River dolphins. For Irrawaddy dolphins, the highest density was found in Dudhmukhi wildlife sanctuary during the monsoon. No Irrawaddy dolphins were found in Dhangmari during the pre-monsoon season; in Chandpai during the dry, pre-monsoon and monsoon seasons; and in Dudhmukhi during the post-monsoon season (Figure 8). No Irrawaddy dolphin calves were observed in the sanctuaries (WCS/BCDP, 2014).

3.2 Administrative and governance context

The Sundarbans Reserve Forest is managed by the Bangladesh Forest Department. From a forest administration point of view, SRF lies in one Circle divided into two Divisions (Sundarbans East and Sundarbans West), four Forest Ranges and 55 compartments. The three dolphin sanctuaries fall under the Sundarbans East Division, which is headed by a Divisional Forest Officer. The Sundarbans East Division has two Range offices - Chandpai and Sarankhola - headed by Range Officers. There are 77 permanent posts in this area under the Forest Department including five sanctuary centers, 16 stations, and 53 patrol posts (29 in the ESRF and 24 in the WSRF) (UNDP, 2016). In addition to the three wildlife sanctuaries that were declared as UNESCO World Heritage Sites, the ten-kilometer periphery of the SRF has been declared as Ecologically Critical Area (ECA) under the Bangladesh Environment Conservation Act of 1995. The ECA intend act as a buffer area also. Further, as mentioned above, in 2012, the Government of Bangladesh notified three more protected areas viz., Chandpai, Dhangmari and Dudhmukhi Wildlife Sanctuaries in the river channels in the Sundarbans, bringing the total extent of protected areas to almost 1,400 km2 or 23% of SRF (UNDP, 2016).

3.3 Socio-economic context

The Sundarbans Reserved Forest covers 52% of the forest of the country and contributes about 41% of the total forest revenue. Interfaced with cultivated lands and intersected by tidal rivers, canals and streams, the Sundarbans forms a resilient buffer for the lives and assets of the three million people who live in its vicinity, as well as a protective shield for the infrastructure and urban populations in Khulna and Mongla international shipping port (MoEF, 2010). In addition to its immense ecological value, the Sundarbans is also a valuable source of timber, fuel , medicinal plants, honey, palm leaves, bees-wax, fish, shells and crustaceans apart from supporting recreational and tourism industry (UNDP, 2016). These forests supply around 45% of the country’s demand for timber and fuel wood (Manju, 2001). During 2008-09, the Government of Bangladesh earned BDT 55.17 million revenue from the Sundarbans, mainly from permits for NTFPs including fish (MoEF, 2010). The 12,000 km of river in the SRF produce large quantities of fish (40 commercially important species) and several species of

46

crustaceans. Among them hilsha shade, catfish, white fish, prawn, shrimp and crab are commercially most valuable. It has been estimated that fisheries in the Sundarbans account for approximately 2% (18,150 metric tons) of the total inland open water capture fishery in Bangladesh (FRSS, 2010; Hossain, 2010). In 2001, there were about 25,000 registered fishing boats to catch fish and crustaceans in the Sundarbans, whereas about 18% households in and around the SRF were dependent on harvesting natural resources, 35% shrimp fry collectors, 33% fishermen, 22% wood cutters, 4% boatmen, 3% Nypa palm frond collectors, 2% crab and shell collectors, and 1% honey collectors (Bernacsek and Haque, 2001; SBCP, 2001). People have migrated to the Sundarbans in recent years in pursuit of better livelihoods, while some communities (e.g. Munda - estimated around 4000 people) have been living in this region for at least 250 years (UNDP, 2016).

3.4 Profile of fishers in the sundarban area

Wildlife Conservation Society provided valuable insights on the socio-economic status of local fishers who strongly depend on natural resources. The families consisted of 0-8 children (average 2.1) of which 52% were male. The level of education among the fishers was poor (39% had no formal education; 47% went only to primary school; 13% went to secondary school but did not complete their education; 1% completed secondary school; and only one fisher completed a higher education certificate). Among school-age children (4-16 years), 75% were enrolled in schools with the remaining having left due to poverty (15%), marriage (7%) and lack of interest or merit (3%). Most of the boys reportedly left schools due to poverty (83%) while girls due to marriage (57%) (UNDP, 2016).

The average monthly income among the fishermen was 3,744 BDT of which 74% came from fisheries and the rest from non-fishery activities. While about 48% had some secondary occupation, only 24% of their income was derived from it. Interestingly, only 4% of their secondary occupations involved harvesting resources from the Sundarbans. A few womenfolk (16%) earned additional income through animal husbandry, bawali, manual labor, fishing, handicrafts, poultry, and tea vending, and tailoring. The fishers use a variety of fishing gears that include: Cast net, Crab line, Crab trap, Creek net, Drag net, Drifting gill net, Fixed floating gill net, Long line, Hook & rod, Long-shore net, Otter fishing, Set-bag net, Post-larvae box net, Post-larvae hand drag net, Post-larvae hand push net, Post-larvae pole net and Post-larvae set- bag net. Of these, gillnets and set-bag nets are the most commonly used gears in the wildlife sanctuaries. Species that are particularly overexploited include the commercially valuable giant

47

tiger prawn or bagda chingri (Penaeus monodon), pangas catfish (Pangasius pangasius), hilsha shade or (Tenualosa ilisha), gray eel-catfish or kainmagur (Plotosus canius) and giant mud crabs (Scylla serratta) (Huda, 2003; Hoq, 2003).

About 77% of the fishermen, used to engage in fishing year-round and 60% of the head fishermen owned boats, mostly non-mechanized. However, only 33% of the fishers owned land (averaging about one tenth of an acre), with 66% of those owning land using it exclusively for their homestead and a few owning additional land for agriculture, aquaculture or poultry. About half (47%) of the fishing operations were conducted by single fisherman, while the others required a crew of 2-4. Of the crew, 82% were paid shares of the catch, whereas the others paid the crew a salary or had family members working without a wage. Permits issued by the Forest Department for fishing trips generally last for a week coinciding with spring tides. Expenses for fishing permit averaged 431 BDT per fishing boat though the official amount was reported to be only 145 BDT. The fishermen generally have to pay to pirates who extort money from them. Most of the fishers live in poor housing conditions - katcha buildings (temporary huts made of mud, bamboo, and Nypa palm thatching with a dirt floor) and pacca buildings (permanent homes made of bricks or tin sheets). Many live on khas (government land) and on channel embankments (UNDP, 2016).

Around 39% of fisherfolk were associated with 30 different NGOs, clubs and societies for loans (95%) and education (5%). Most fishers (58%) sold their catch for a fixed price to either fish depots (54%), fish collectors (31%), money lenders (8%), directly to consumers (4%), or to fish or shrimp farms (3%). Only 9% of their fish catch was reportedly consumed by the fishermen and their families (UNDP, 2016).

Overall, the fishers of the sundarban areas have a highly backward socio-economic status that strongly influences their resource-use practices. The available natural resources are already being intensively used by the local people for eking out day-to-day livelihoods including basic nutritional requirements. The complex interplay of the natural ecology and human systems (the latter including local use as well as the upstream freshwater diversions and climate change) is the primary driving factor behind the rapid degradation of the Sundarbans as witnessed today (UNDP, 2016).

3.5 Fisheries in Sundarbans

Sundarbans being the nursery for nearly 90% of the aquatic species of eastern coast, the coastal fishery of eastern India is dependent upon Sundarban. Jhingran (1977) recorded a total of 172

48

species from a variety of sources and also mentioned that the diversity of the Hooghly-Matlah estuary increases along an increasing salinity gradient. Numerous species (estimated to be 400) are known to use mangrove swamps as nursery grounds (Gundermann and Popper, 1984; Lowe-McConnell, 1987). Apart from fish species, there are 20 identified species of Prawns and 44 species of crabs including two edible ones. For fishes, the Sundarbans function as nursery grounds for important commercial species of the continental shelf that are harvested in India and neighboring countries. The Sundarban delta provides physiologically suitable environment with respect to temperature, salinity and other physico-chemical parameters. Generally estuary receives abundant supply of nutrients from land drainage and large quantities of organic detritus which is an important source of energy for a wide variety of estuarine consumers.

3.5.1 Fish species Lates calcarifer (Bloch), Tenualosa ilisha (Hamilton-Buchanan), Liza parsia (Hamilton), Liza tade (Forsskal), Harpadon nehereus (Hamilton-Buchanan), Plotosus canius (Hamilton- Buchanan), Pampus argenteus (Euphrasen), Rhinobatos annandalei Norman, Pangasius pangasius (Hamilton-Buchanan), Polydactylus indicus (Shaw), Chanos chanos (Forsskal), Eleutheronema tetradactylum, Polynemous indicus, Polynemous paradiseus (Linn.) and Pama pama (Hamilton).

3.5.2 Crustacean species Panaeus monodon (Fabricius), Panaeus penicullatus (Milne-Edw) and Metapenaeus monoceros (Fabricius). Edible crabs mainly Scylla olivacea (Forsskal) and Neptunus pelagiens.

3.5.3 Common gears

The common gear used in the Sundarbans are dragnets (sarengijal, berjaal), shore seines (jaqnga jal, kochal jal), stakenets (charpata and khalpatta), gillnets (galsha), and fixed bagnets (beoundi ja, bindi jal) (Mukherjee, 2007) These are used in the inland waters of the Sundarbans and in the inter-tidal waters.

3.5.4 Destructive gears

The fishing gears that are considered destructive include the small mesh-sized beoundi jal and other fine-meshed nets. Besides these, castnets and hooks-and-line are also used. The common fish caughtin the inter-tidal waters are bhetki (Lates calcalifer), shimur, gandu or medha mach, chingree (shrimp), selia, chadba, bavta and red shrimp. The significant inland fish landing centres in the Sundarbans include Canning, Herobhanga and

49

Gosaba. Fishers in most of the remote islands do not have access to ice or other means to preserve their catch, and are often forced to travel to Canning or Gosaba to sell their catch on the same day itself, or transfer the catch to fish merchants who come to the villages. The fish depot owners, as the fish merchants (Aratdars) are called, also play the role of money lenders, serving fishers who often do not have the money to buy boats and nets and to cover the running costs 41 of fishing. The Aratdars, besides lending money, also arrange for the marketing of the catch from the villages.

3.5.5 Illegal fishing

Poison fishing: Fishing by poisoning and explosives sporadic reports have been filed on fishing by poisoning with certain chemicals in some areas of the Sundarban. This practice, however, is not permissible by law. A few drops of poison are all it takes to decimate fish and crustacean stocks in a Sundarbans canal. The poachers who cruise the waterways of the world's largest mangrove forest in search of valuable shrimp and crabs regularly use poison. Crustaceans clamber ashore within minutes to escape the toxin and are easily collected. Fish die en-masse, carcasses left to float away on current and tide (Wikipedia-2).

3.5.6 Livelihoods of Sundarban resource users A large number of Sundarbans populations are engaged in fisheries and allied activities. Fisheries remain to be the sole livelihood of fisherman and their family residing in Sundarbans. Collection of fish seeds and adults especially of Paeneus monodon, from the nature is one of the main sources of earning of the coastal fisher folk. The fisher folk are using mechanized as well as non-mechanized crafts. Trawlers, gill-netters, purse seiners, etc. are among mechanized

50

crafts and plank built boats, dug-out canoes and catamarans are under non mechanized crafts. A number of fishing gears are being used in Sundarbans viz. trawl nets, purse seines, drift/gill nets, boat seines, fixed bag nets, hooks and lines, shore seines, traps, scoop nets, etc. Most fishing is undertaken by men, crab fishing and prawn seed collection are practiced by both men and women in the inter-tidal waters. Besides fishing, most people have other sources of livelihood, also seasonal, such as small businesses and mono-crop agriculture (Jalis, 2007). Some work as daily labours. Prevalent cultural belief systems and myths of traditional communities in Sundarbans are predicated on a deep respect for nature.

3.5.7 Killing fish stocks in Sundarbans Fisherfolk in the Sundarbans wilfully ignore the government ban on the use of fine-mesh current nets which is fast depleting various species of fish in the area. The livelihoods of a few hundred fishermen and their families operating in Khulna's Dacope upazilla depend on their catching fish and juvenile shrimp. Although it is the job of the forest department to work with the Coast Guard to enforce the ban on the use of illegal variety of net, there is little by way of enforcement of the law. Unfortunately, some unscrupulous forest department officials and traders which lets this unhealthy practice to continue. We are disheartened to see authorities turning a blind eye to the rampant use of banned fine-mesh fishing nets in the protected mangrove forest of the Sundarbans, home to many unique species of fish. With the gradual reduction of fish that are indigenous to the waterways in and around the Sundarbans, environmental experts calculate that fisherfolk are destroying on average around 200 fish fry to catch one juvenile shrimp. The result of such irresponsible behaviour is the havoc that is caused to the natural breeding patterns of many types of fish and the decline in fish stocks is a natural result. The government should help these few hundred fishermen and their families to adopt alternative means of livelihood and haul up the corrupt officials who connive in this illegal activity and make examples of them (Wikipedia-1).

3.5.8 Sundarbans: Fisheries and Fishing Communities

Fishers in the Sundarbans are organized largely into two unions—the United Fishermen’s Association and the Sundarban Matsajibi Joutha Sangram Committee. The 24 Parganas South District has 6,205 mechanized craft, 1,028 motorized craft and 6,046 non-motorized craft fishing in marine waters (CMFRI, 2005). The mechanized fishing vessels in the 24 Parganas South District include trawlers, large gillnetters and dol-netters, fishing outside the Sundarbans forest area, in the Bay of Bengal. Naukas are the traditional boats used in the inland waters of

51

Sundarbans, which range from 24 ft to 42 ft in overall length. Some of the motorized boats fishing in the reserve forest area have motors of 12 hp to 24 hp.

3.6 Gaps in existing management and conservation

1. Wildlife protection act 2012: in section 14 article 35, if any person does any act prohibited under section 14, he shall be deemed to have committed an offence and shall be non-bailable for such offence and be punished with imprisonment for a term not exceeding 2 (two) years or with a fine of Taka not exceeding 1 (one) lac or with both, and in case of his repetition of the same offence, he shall be punished with imprisonment for a term not exceeding 5 (five) years or with a fine of Taka not exceeding 4 (four) lac or with both (Annexure 1). At present this act might be reasonable. But it is important to ensure the implementation of punishment, sometimes social or political influential person escape from this punishment. This kind of act could be updated after few years (12-15 years). 2. Fish hatchery act, 2010 and Fish hatchery rule, 2011: beyond the article no. 4-12 mentioned in the fish hatchery act-2010 and fish hatchery rule-2011, further improvement should be considered: Brood bank development, reducing brood fish/ shrimp collection from nature, banning brood collection in spawning season, discharge treatment etc. 3. Protection and conservation of Fish Act, 1985, Modification (2000): “(1A) No person shall catch or cause to be caught fry or post larvae of fish, shrimp and prawns of any kind, in any form and in any way in the estuary and coastal waters of Bangladesh.” Wild fry and PL are available in local market. Should have a strict regulation on many other exotic species (Annexure 2). 4. Protection and conservation of Fish Act, 1985, Modification (2011): Article 13: Catching of all kinds of fishes prohibited in certain period in particular areas (1), no person shall catch or cause to be caught-all kinds of fishes in the Hilsha fish sanctuary area mentioned in column (2) during the period mentioned in column (4)…. (five different hilsha fish sanctuary areas) (Annexure 3). Like hilsha fishery, separate fish sanctuaries should be developed for other commercially and biologically important fish species in Sundarbans area, or the area of existing fish sanctuaries can be expanded for better conservation. At this moment, it is important to identify dolphin feed, determine the breeding boundary of those fishes (dolphin feed) and declared the boundaries as fish sanctuary.

5. Protection and conservation of fish Act, 1985: In article 12-16, it has been mentioned that using net (e.g. current net, Japanese current net, fash net, fandi net, kappa net, badha net and kathi net) with the mesh size 4.5 cm of below is prohibited (Annexure 4). In contrast, Forest Department mentioned in Integrated Resource Management Plans for the Sundarbans (page 116, section 5) reported that fishing net with mesh below 15mm/1 inch (knot to knot at stretch condition) will not be allowed for fishing. However, fishing traps and hooks will not have any limit. This regulation is contradictory with the Protection and conservation act 1985. 6. Marine Fisheries Ordinance, 1983, (XXXV of section 55, rule 7, modification 2004): no fishing vessel shall throw any of its catch of fish or any aquatic resource, except marine turtle, in the sea. Marine Fisheries Ordinance, 1983, (XXXV of section 55, rule 14A, modification 2006): use of turtle extruder device-Every shrimp trawler shall use Turtle Extruder Device with net/nets during trawling. Same kinds of rules should be developed and implemented for dolphin and other aquatic mammals. 7. Fisheries act 1995 section 112(1) Use of explosives, poisons, substances or equipment for fishing (1) unless authorized under this Act or under any other Act, a person must not use, or attempt to use, any explosive in Victorian waters. Penalty: 100 penalty units or imprisonment for 6 months or both. (2) Unless authorized under this Act or under any other Act, a person must not use, or attempt to use, any poison, substance or equipment in Victorian waters if the use of the poison, substance or equipment can reasonably be expected to result in— (a) the taking or killing of any fish, fishing bait or protected aquatic biota; or (b) damage to the habitat of any fish, bait or protected aquatic biota. Penalty: 100 penalty units or imprisonment for 6 months or both. (3) If a court finds a person guilty of an offence against this section, the court may, in addition to any other penalty imposed by it, order the person to pay compensation for any damage or loss caused by the offence to any person. Poison fishing is not only destructive for fish but also huge loss for food chain and aquatic system. Therefore, punishment could be increase, for first time offence punishment could be 300 penalty unit or imprisonment for one year or both 2nd time its double. 8. According to East Bengal Protection and Conservation of Fish Act, 1950: in section 2 and 3, the rules have been mentioned that- (2) The Provincial Government may, by notification, apply rules or any of them to any water or waters, provided that no such rules shall apply to any private water except with

53

the consent in writing of the owner thereof and of all persons having for the time being any right of fishery therein. (3) Such rules may- a) Prohibit or regulate all or any of the following matters, that is to say,-(i) the erection and use of fixed engines; (ii) the construction, temporary or permanent, off-weirs, dams, bunds, embankments and other structures. b) Prohibit the, destruction of, or any attempt to destroy, fishes by explosives, gun, bow and arrow in inland water or within coastal territorial waters; c) Prohibit the destruction of, or any attempt to destroy, fishes by the poisoning of water or the depletion of fisheries by pollution, by trade effluents or otherwise; (d) Prescribe the seasons during which the killing or catching of fishes of any prescribed species shall he prohibited; These rules are key points for managing any natural fish stock, however, proper implementation is the question of its failure throughout years. Different Governments and countries do not follow the rules of fish protection, or often break the international laws of natural water flow by developing huge dams, and other structures. For proper conservation of Dolphin and its foods, proper implementation of these rules might be perfect initiatives. 9. No. 3281-Fish.-27th March 1951—In exercise of the power conferred by section 3 of the East Bengal Protection and Conservation of Fish Act, 1950 (East Bengal Act XVIII of 1950), the Governor is pleased to make the following Rule:— Rule: No person shall catch or cause to be- caught carp fishes (i.e., Rohu, Mrigal, Katla; Kalbaus and Ghunia) daring the period from the first April to the 30th June in any year in the places mentioned in different Schedule (Annexure 5). 10. No. 12889 FiSh.-27th December 19th—In exercise of the powers conferred by section 3 of the East Bengal Protection and Conservation of Fish Act, 1950 (East Bengal Act XVIII of 1950), the Governor is pleated to Make the following Rule:— Rule: No person shall catch or cause to be caught carp fishes (i.e., Rohu, Katla, Mrigal, Kalbaus and Ghunia) during the period from 15th March to the 30th June in any year in the places mentioned in the Schedule below: River Halda from its mouth in the river Karnafully near katurghat bridge up to Sattarghat ferry, police station, Hathazari and Raozan, District (Annexure 6). 11. In East Bengal Protection and Conservation of Fish Act, 1950: No. 6497 (Annexure 7), 6972 (Annexure 8), 15107 (Annexure 9), 15135 (Annexure 10), 14356 (Annexure 11),

54

2501 (Annexure 12); different rules on embankments, provisions on sizes of fish to be caught, fishing nets (new rules Protection and Conservation of Fish Rules, 1985, Act XVIII of 1950, section 3(5)) etc. have been mentioned, which need to be implemented strictly through government bodies, or need to be regulated strictly by more penalties and imprisonment.

4 Guidelines for biodiversity friendly Dolphin sanctuaries effectiveness

4.1 Guidelines for fisheries

4.1.1 Mesh size regulation

Existing rules for fisheries management and conservation (e.g. gear restriction) shall be imposed properly. Mesh size of different nets shall be controlled strictly. All kinds of nets shall be banned in the sanctuary areas according to the Protection and Conservation of Fish Act, 1985; such as (e.g. current net, Japanese current net, fash net, fandi net, kappa net, badha net and kathi net). Mesh size of the nets shall not be below 15 mm in catching fish in SRF (IRMP, 2010). Mesh size regulation according to IRMP shall be specified considering other fish biodiversity, and circulated to fishers and other associated personnel for proper implementation of regulation. However, different resource users and public have different opinion on strengthening this regulation.

4.1.2 Habitat restoration

The forest department and respective authorities shall take necessary action for implementation of habitat restoration programs, including development of fish pass or fish screen, instream habitat structure (e.g. boulder or log weirs, dams and deflectors, cover structures, rootwads and brush bundles, gabions, etc.), and development of artificial reefs for improvement of fish and crustacean spawning habitat.

4.1.3 Controlling upstream river flow and tidal river management

River management sector, water development board or other responsible authorities of the country shall ensure adequate freshwater flow from the upstream by implementing mega projects through dredging and managing tidal river flow across the SRF and other coastal rivers for protection of breeding and nursery grounds of fish, crustaceans and dolphins, conserving their habitats and establishing food web structure in SRF.

4.1.4 Identification of fish and dolphin feeding, nursery and breeding ground Forest department shall specifically identify the feeding and nursery ground of major fishes and dolphin in sundarbans. Besides, major breeding grounds of those fishes shall be identified through extensive research. Following their finding the forest department shall make new decision to expand or to create new sanctuaries.

57

4.1.5 Expansion of sanctuary areas

Forest department will indicate more protected areas or identify additional buffer zones to provide further support for increased aquatic biodiversity. Forest department will decide to expand the area of existing sundanban aquatic sanctuaries, or they shall create new sanctuaries based on the fish and dolphin hot-spot areas. Even whole sundarbans can be declared as the sanctuary areas for fish and other wildlife animals.

4.1.6 Fisheries stock assessment

Forest department by the assistance of Department of Fisheries, Fisheries Research Institute, Universities and experts shall urgently assess the present fisheries stocks in SRF, thereby, they shall determine the Total Allowable Catch (TAC) beyond the sanctuary areas. Mathematical models shall be developed for future estimation or assessment of fish stocks during uncertainties. DOF will also consider the sustainability of SRF resource management for future generations through ecosystem approach.

4.1.7 Catching fish larvae beyond SRF

Department of Fisheries shall strictly control massive non-selective catch of fish fingerlings and crustacean larvae in small mesh mosquito nets beyond the SRF areas in the coastal rivers.

4.1.8 Control of pollution and industrial development

Biggest concerns shall be taken for protection of Sundarban biodiversity on chemical and sound pollution, and toxic contamination from oil tankers, coastal industries, Mongla port, Rampal power plant station, EPZ, coastal power plants, agriculture and fisheries, navigation, tourisms, and large upstream human population centers. BIWTA and Ministry of Navigation shall be combindly empowered vessel registration power, controlling navigation routs, minimizing transportation across sundarbans and controlling the registered vessels through Global Positioning Systems (GPS). City corporations and municipal authorities shall be responsible for waste management and its safe disposal into open waters. Government shall be well aware of municipal sludge and faecal sludge treatments. All the industries beyond 10 km of SRF periphery shall be categorized as red listed and other industries outside this area without waste treatment facilities shall be banned. In 2017, the High Court already directed the

58

government not to allow any industrial unit to be set up within 10 kilometers of the Sundarbans mangrove forest (The Daily Tribune, 24 August 2017).

4.1.9 Fishing ban

Fishing shall be prohibited in the sanctuary areas. Beyond the sanctuaries fishing shall be controlled during breeding seasons according to IRMP (2010), for instance, fishing ban in all canals during the months of July and August and fishing ban in the Beels/Chatals of the Sundarbans during February-March. However, the forest department shall have more research based evidence on reorganizing ban in breeding seasons. Fisherman shall be encouraged about not to use any kind of fishing trap in the sanctuary areas. By imposing gear restriction regulation overall fisheries and biodiversity of Sundarban fish sanctuaries will be increased, thereby enhanced habitat and food availability of dolphin will be ensured.

4.1.10 Sustainable fisheries

Farmers shall be encouraged for sustainable fishing from natural stocks for future generation. Fishing shall be done in the shallow water because dolphins are found in the deep water.

4.1.11 Illegal fishing

All kinds’ illegal fishing, like fishing using poisons, explosives, chemicals or plant extracts shall be prohibited by laws and implemented accordingly.

4.1.12 Navigation routs There has to be an alternative navigation route and the drivers shall be aware of the fact that not to make much disturbances in the aquatic environment. The ministry of navigation shall take care of the entire navigation root through Sundarban and check the fitness of the crafts. In sanctuary areas any types of disturbing motorized vessels shall be prohibited, or the speed of the vessels shall be controlled while passing through protected areas. Any ships drowned in protected areas or natural conserved areas shall be rescued immediately to minimize oil spilling or other polluted waste materials.

59

4.1.13 Disposal of industrial wastes There shall have strict regulation for the disposal of industrial wastage to the Sundarban adjacent water bodies. Industrial wastage is full with different types of toxic chemicals and heavy metals. Those pollutants are responsible for indiscriminant killing of fish, shellfish and aquatic mammals. Thereby, through restricting the disposal of industrial sewerage into the rivers might greatly improve the natural biodiversity and dolphin habitats in Sundarbans.

4.1.14 Livelihoods The government will create alternative livelihood options for Sundarban resource users (e.g. fishers, aquaculturists, agriculturists, etc.) for better management of dolphin resources. In the vulnerable coastal Sundarban areas the government will emphasis on involvement of fishers on small scale agricultural productions (e.g. rice, vegetable, or other food items), rearing livestock or poultry, day labour, small scale grocery, transportation (land and water), tourism with small boat, tailoring, handicrafts, etc.

4.1.15 Physical construction in water ways Strict regulation shall be implemented in dam and bridge construction in flowing rivers having dolphin and other fish’s migratory routs.

4.1.16 Task-force and volunteer committee A task-force committee shall be formed by participation of different sectors to protect the natural resources of sanctuaries or other nature reserved areas. The forest and fisheries department shall develop volunteer groups to rescue trapped dolphins in their habitat.

4.1.17 Licensing and fishing permit Licensing power for fishing from the Sundarban areas or from declared sanctuaries shall be according to IRMP 2010; e.g. maximum number of boat license certificate (BLC) issuance will annually be 12,000 for the Sundarbans and it will be equally distributed for the two Divisions of East and West (6,000 each). Fishing permits shall be set based on IRMP (2010), for instance, one BLC holder boat will get fishing permits a maximum of 8 times in a year for all gears or fishery type with a maximum limit of 3 times in a month and maximum 7 days per permit. Besides, catching of hilsha and Pangasius below 23 cm is prohibited during November-April and for male crab, the minimum weight size for catch is 200g and for female as 120g (IRMP, 2010).

60

4.1.18 Empowering mobile court Government Forest and Fisheries officers shall be empowered with executive magistrate to conduct mobile court more frequently when necessary. Limit of punishment through mobile court shall be increased from two years to maximum five years. The penalty shall be also increased up to double or triple of the existing amount.

4.1.19 Inter-sectoral responsibilities Different stakeholders shall take key responsibilities for protection of aquatic biodiversity. Policies shall be developed and implemented through integrated approach of inter-sectoral involvement of different ministry. All the sectors of aquatic resource management (e.g. aquatic mammals, fisheries, plants) shall be incorporated under broad researches. The roles of stakeholders are given below: Table 2. Responsibilities of stakeholders for protecting aquatic biodiversity in Bangladesh Sundarbans sanctuary areas.

5 Conclusion

Dolphins and cetaceans are the beauty in aquatics system and valuable resources in our oceans. So for the protection and conservation of this precious resource in Sundarban sanctuaries combine effort and action is very necessary among the resources users. A good collaboration among the direct resources user more especially the fisherman and other users i.e. local and international NGOs, governments bodies and stakeholder can play significance role on protection of dolphins in Sundarban estuaries. It is also necessary to proper implement of existing rules and regulation for the conservation of dolphins. Finally awareness program should be continued among the beneficiaries of Sundarban estuaries.
