Kishore, IAS कृषि भिन, नई कि쥍ी -110001 Joint Secretary Govt. of India Ministry of Agriculture and Farmers Welfare Department of Animal Husbandry, Dairying & Fisheries Krishi Bhavan, New Delhi - 110001 Message Fisheries touch our lives in countless ways. If well maintained, they can feed millions of people, generate jobs and income, help maintain log-standing community and cultural traditions, and provide a range of products. World Fisheries Day, observed annually on November 21st, is an opportunity to reflect on the importance of fisheries around the world and what we can do to ensure that they stay healthy and productive. Neel Kranti Mission - 2016, envisages “Creating an enabling environment for integrated development of the full potential of fisheries of the country, along with substantial improvement in the income status of fishers and fish farmers keeping in view the sustainability, biosecurity and environmental concerns”. Fishers, the backbone of the Neel Kranti Mission, are going to be benefited through the schemes initiated by the Govt. of India. Fish farmers are covered under insurance scheme and many fishermen are also being provided relief during the non-fishing season. I hope World Fisheries Day celebration will contribute significantly in creating awareness and successful promotion of ‘Blue Revolution’. Date: 10/11/2017 New Delhi (B.

Over the decades, the country made rapid strides in the fisheries sector progressing initially from subsistence fisheries to commercial fisheries and subsequently, with transfer of technology from lab to land, commercial aquaculture in the country recorded exponential growth. Currently, with an annual production of about 10.80 million tonnes India stands second among the leading fishing nations in the world and nearly 70% of this production comes from Inland Capture Fisheries and Freshwater Aquaculture. The overall growth that the country has achieved in Fisheries and Aquaculture Sector is being celebrated on the World Fisheries Day on 21st November 2017 with the participation of a cross section of the stakeholders involved. On this occasion a Souvenir is being brought out with 11 articles written by some of the leading fisheries scientists and academicians in the country. A wide variety of topics of interest, covering some of the issues that the sector is facing as well as the opportunities that are available to enhance fish production and productivity, are presented. The significant points made in the articles are worth mentioning here. The Fisheries sector in India evolved from artisanal fishing to sophisticated technologically advanced fishing industry through excellent scientific innovations and infrastructure. Studies made in the country over the years have led to the need for implementing measures to conserve natural resources using selective fishing gear. Issues of seed quality and disease incidence in shrimp aquaculture were tackled with better management and diversification of species. New technologies such as cryopreservation of gametes, genomics, biofertilization, etc., have made aquaculture more efficient and specialized. In situ conservation, stock enhancement through ranching, ex situ conservation through cryopreservation of gametes and embryos, tissue banking, DNA Bar-coding, development of fish cell lines for fish virology studies would lead to improving the nation’s fish wealth. The Eastern Himalayas are home to rich freshwater fish diversity exemplified by 596 species under 123 genera and 37 families that are threatened by overexploitation, pollution, habitat degradation, climate change and invasion by exotic species. A case study on management of multi-use water bodies in Chhattisgarh reveals the intricacies, conflicts among stakeholders, the nature of technical, socio-economic-cultural-political and environmental interdependencies. Freshwater aquaculture requires diversification of fish species including small and indigenous species, integrated fish farming, cage and pen culture, opening of one-stop aqua shops, and skill development. Fish health issues in aquaculture arise from breakdown of balance between host, pathogen and environment, emerging pathogens, trans-boundary movement of live animals and live feeds, use of antibiotics and veterinary drugs, and there is an urgent need for aquaculture certification. Sea Cage Farming provides immense opportunities for enhancing marine fish production while simultaneously reducing fishing pressure on natural stocks and providing livelihood to coastal communities. Artificial Reefs are found to restore marine ecosystem and enhance marine fish production with community participation and ownership along Tamil Nadu coast. There is immense scope for development of Ornamental Fisheries in the country. Hatchery technology for production of 10 marine ornamental fishes has been standardized at ICAR-CMFRI; success was achieved in the case of Clownfish, Damselfish and Firefish. Also a method has been developed for sustainable trade from wild collection of ornamental fish. Advanced technologies adopted at ICAR-CIFT are being popularized for post-harvest fish processing and packaging to enhance the safety and shelf-life of fish products, and a variety of value-added products, ready to serve fish products, extruded products and fishery byproducts have been developed. I compliment the authors for their valuable contributions that not only trace the growth of the fisheries sector in the country and highlight the technological advances made but also show us the way forward for sustainable fisheries development in the country. I would also like to place on record my sincere appreciation to Dr. K. Ravindranath, Senior Consultant (Technical), NFDB, for the excellent editing. Hyderabad 17 November 2017 (I.

    Playing with Matches

    PLAYING WITHHybrid MATCHES: They can fuel the fires of conservation or burn everything to the ground 62 CORAL Clownfishes by Matt Pedersen RILEY COULDN’T UNDERSTAND IT: her mated pair of “Tomato Clownfish” kept spitting out a strange mix of offspring, some with black ventral and anal fins, others with white tails, but otherwise looking like their red parents. Meanwhile, Brennon struggled to identify the clownfishes he had picked up from a distant aquarium shop on a road trip; the label said “Onyx Percula,” but the fish lacked the bright orange eye that Amphiprion percula should have. Melanie was disappointed when her “True Sebae” clownfish never grew their full vertical bars and always seemed to have black tails with a hint of a yellow tail bar instead of the all-yellow tail she had come to expect. Although Riley, Brennon, and Melanie are not their real names (I am trying to protect the innocent here), these dramatizations are all too real. Hobbyists (and, to be honest, some peo- ple in the marine livestock trade) have often White-Bonnet Anemonefish (Amphiprion leucokranos) in Milne Bay, Papua New Guinea.

    The Maroon Clownfish Sea Hares in the Aquarium

    FREE ISSN 1045-3520 Volume 22 Issue 1, 2005 Sea hares in the Aquarium Photo by Bob Fenner Julie Van Horn Most aquarists regard sea slugs with one idea in mind: algae eaters. It is true that they do eat large quantities of algae, but sea slugs are singular creatures in their own right. First it is important to distinguish among the types of sea slugs. The sea slugs most commonly appearing at an aquarium store near you are likely either nudibranchs or sea hares. Nudibranchs are generally less than a few inches in length, brightly colored and have highly specific dietary requirements. Sea hares are significantly larger, less brightly colored and have more general diet preferences. Responsible aquarium keepers know what they are buying and its proper care. Many people have heard of nudibranchs, but sea hares are a different story. A sea hare in an aquarium store is likely to be of the genus Aplysia (Photo 1). A sea hare from the species Bursatella is shown in Photo2. The largest Aplysia is the California sea hare (Aplysia californica), which can grow to 3 three feet in length! Not to worry though, this kind of growth is unlikely in a Premnas biaculeatus - A beautiful but ornery clownfish home aquarium. Sea hare growth is limited by the quality and quantity of food they receive.

    An Overview of Marine Ornamental Fish Breeding As a Potential Support to the Aquarium Trade and to the Conservation of Natural Fish Populations

    L.M. Domínguez & Á.S. Botella, Int. J. Sus. Dev. Plann. Vol. 9, No. 4 (2014) 608–632 AN OVERVIEW OF MARINE ORNAMENTAL FISH BREEDING AS A POTENTIAL SUPPORT TO THE AQUARIUM TRADE AND TO THE CONSERVATION OF NATURAL FISH POPULATIONS L.M. DOMÍNGUEZ & Á.S. BOTELLA Grupo de Investigación en Acuicultura, ULPGC & ICCM, Telde, Canary Islands. ABSTRACT The aquarium fi sh trade moves more than two billion live fi sh worldwide per year. For fresh water organisms, more than 90% of them are captive bred, but over 90% of commercial marine organisms are wild-caught. Wild-caught organisms come mainly from coral reefs and adjacent areas. Destructive collection techniques, such as cyanide, quinaldine, even dynamite or explosives, are commonly used. These techniques not only affect the target fi sh but causes terrible damages to the ecosystems and the reef habitat itself, as well as coral and crustacean bleaching. This damage has not been assessed globally, but locally, where populations have been overharvested; it has created environmental imbalances due to the selective fi sheries focused on a few species, sexes or ages with high market value. A number of measures can be taken in order to reduce the environmental damage. The most important depend largely on the efforts by local governments, community groups, environ- mental organisations and the private sector. The fi nal objective of these measures is to place the ornamental trade on a sustainable basis. Moreover, new research into aquaculture technology on target species with the aim of diminishing the fi shing pressure on wild stocks as well as increasing the effectiveness of aquaculture facili- ties must be carried out.

    Alarm bells over rising pet trade in wild animals in India INFOCUS feature..... TRAFFIC Post TRAFFIC Post is TRAFFIC’s newsletter on wildlife trade in India. It was started in September 2007 with a primary aim to create awareness on rampant poaching and illegal wildlife trade in India and how it affects the endangered flora and fauna. Since then it has covered not only issues related to illegal wildlife trade but also highlighted policies and trends related to legitimate wildlife trade especially in timber and medicinal plants. The newsletter began as a quarterly e-newsletter available only for online distribution. However after a few issues it was converted into a printed edition with three issues coming out every year. The response to the newsletter over the years has been overwhelming and the subscribers continue to increase with every issue. Besides carrying updates on TRAFFIC’s work in India in a given period, the newsletter focuses on the plight of various species in illegal wildlife trade. It also provides early warning through its various sections on illegal wildlife trade trends. The CITES section and the OUTPOST section especially is meant to keep its readers updated on global news related to wildlife trade. Managing Editor: Dilpreet B.

    Parasites and Cleaning Behaviour in Damselfishes Derek

    Parasites and cleaning behaviour in damselfishes Derek Sun BMarSt, Honours I A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2015 School of Biological Sciences i Abstract Pomacentrids (damselfishes) are one of the most common and diverse group of marine fishes found on coral reefs. However, their digenean fauna and cleaning interactions with the bluestreak cleaner wrasse, Labroides dimidiatus, are poorly studied. This thesis explores the digenean trematode fauna in damselfishes from Lizard Island, Great Barrier Reef (GBR), Australia and examines several aspects of the role of L. dimidiatus in the recruitment of young damselfishes. My first study aimed to expand our current knowledge of the digenean trematode fauna of damselfishes by examining this group of fishes from Lizard Island on the northern GBR. In a comprehensive study of the digenean trematodes of damselfishes, 358 individuals from 32 species of damselfishes were examined. I found 19 species of digeneans, 54 host/parasite combinations, 18 were new host records, and three were new species (Fellodistomidae n. sp., Gyliauchenidae n. sp. and Pseudobacciger cheneyae). Combined molecular and morphological analyses show that Hysterolecitha nahaensis, the single most common trematode, comprises a complex of cryptic species rather than just one species. This work highlights the importance of using both techniques in conjunction in order to identify digenean species. The host-specificity of digeneans within this group of fishes is relatively low. Most of the species possess either euryxenic (infecting multiple related species) or stenoxenic (infecting a diverse range of hosts) specificity, with only a handful of species being convincingly oioxenic (only found in one host species).
