The Conservation Action Plan the Ganges River Dolphin
THE CONSERVATION ACTION PLAN FOR THE GANGES RIVER DOLPHIN 2010-2020 National Ganga River Basin Authority Ministry of Environment & Forests Government of India Prepared by R. K. Sinha, S. Behera and B. C. Choudhary 2 MINISTER’S FOREWORD I am pleased to introduce the Conservation Action Plan for the Ganges river dolphin (Platanista gangetica gangetica) in the Ganga river basin. The Gangetic Dolphin is one of the last three surviving river dolphin species and we have declared it India's National Aquatic Animal. Its conservation is crucial to the welfare of the Ganga river ecosystem. Just as the Tiger represents the health of the forest and the Snow Leopard represents the health of the mountainous regions, the presence of the Dolphin in a river system signals its good health and biodiversity. This Plan has several important features that will ensure the existence of healthy populations of the Gangetic dolphin in the Ganga river system. First, this action plan proposes a set of detailed surveys to assess the population of the dolphin and the threats it faces. Second, immediate actions for dolphin conservation, such as the creation of protected areas and the restoration of degraded ecosystems, are detailed. Third, community involvement and the mitigation of human-dolphin conflict are proposed as methods that will ensure the long-term survival of the dolphin in the rivers of India. This Action Plan will aid in their conservation and reduce the threats that the Ganges river dolphin faces today. Finally, I would like to thank Dr. R. K. Sinha , Dr. S. K. Behera and Dr. -

Species Composition and Invasion Risks of Alien Ornamental Freshwater
www.nature.com/scientificreports OPEN Species composition and invasion risks of alien ornamental freshwater fshes from pet stores in Klang Valley, Malaysia Abdulwakil Olawale Saba1,2, Ahmad Ismail1, Syaizwan Zahmir Zulkifi1, Muhammad Rasul Abdullah Halim3, Noor Azrizal Abdul Wahid4 & Mohammad Noor Azmai Amal1* The ornamental fsh trade has been considered as one of the most important routes of invasive alien fsh introduction into native freshwater ecosystems. Therefore, the species composition and invasion risks of fsh species from 60 freshwater fsh pet stores in Klang Valley, Malaysia were studied. A checklist of taxa belonging to 18 orders, 53 families, and 251 species of alien fshes was documented. Fish Invasiveness Screening Test (FIST) showed that seven (30.43%), eight (34.78%) and eight (34.78%) species were considered to be high, medium and low invasion risks, respectively. After the calibration of the Fish Invasiveness Screening Kit (FISK) v2 using the Receiver Operating Characteristics, a threshold value of 17 for distinguishing between invasive and non-invasive fshes was identifed. As a result, nine species (39.13%) were of high invasion risk. In this study, we found that non-native fshes dominated (85.66%) the freshwater ornamental trade in Klang Valley, while FISK is a more robust tool in assessing the risk of invasion, and for the most part, its outcome was commensurate with FIST. This study, for the frst time, revealed the number of high-risk ornamental fsh species that give an awareness of possible future invasion if unmonitored in Klang Valley, Malaysia. As a global hobby, fshkeeping is cherished by both young and old people. -

Coldwater Fish Diversity of India and Its Sustainable Development A
Coldwater Fish Diversity of India and Its Sustainable Development A. K. Singh* and M. S. Akhtar ICAR-Directorate of Coldwater Fisheries Research, Bhimtal-263136, Nainital, Uttarakhand *Email: [email protected] Introduction India is one of the mega biodiversity hotspots in the world and occupies the 9th position in terms of freshwater mega biodiversity (Mittermeier et al., 1997). Biodiversity is essential for stabilization of ecosystems, protection of overall environmental quality, for understanding intrinsic worth of all species on the earth (Ehrlich and Wilson, 1991). The country is bestowed with vast and varied coldwater/hill fishery resources which are spread over the Himalayan and peninsular regions as upland rivers, streams, high and low altitude natural lakes and reservoirs. There are around Fig. 1 : Number of species present in the North-East India 8,243 km long streams and rivers, 20,500 ha (Ali, 2010) natural lakes, 50,000 ha of reservoirs, both natural and manmade, and 2500 ha brackish water lakes in central Himalaya and 91 from the Deccan plateau the high altitude (Mahanta & Sarma, 2010).

Seasonal Hydrology Shifts Production Sources Supporting Fishes in Rivers of the Lower Mekong Basin
1342 ARTICLE Seasonal hydrology shifts production sources supporting fishes in rivers of the Lower Mekong Basin Chouly Ou and Kirk O. Winemiller Abstract: Seasonal hydrology is assumed to be an important reason why the Lower Mekong Basin supports highly productive and biodiverse inland fisheries. We used C and N stable isotope ratios of tissue samples to estimate primary production sources supporting fish biomass in the Mekong and three large tributaries in Cambodia. We used a Bayesian mixing model to estimate relative contributions of four alternative production sources — seston, benthic algae, riparian grasses, and riparian macro- phytes. There was little seasonal variation in isotopic signatures of riparian plants, but benthic algae and seston showed large seasonal shifts in carbon ratios. Seston and benthic algae were the most important production sources supporting fish biomass overall during the dry season, and riparian vegetation was the most important source during the wet season. Sources contributed differentially to biomass of trophic and habitat guilds, especially during the dry season. A dam on the upper Sesan River has changed hydrology, channel geomorphology, and other factors and, compared with the other three rivers, its fish biomass appears to derive from algae to a greater extent. Résumé : L’hydrologie saisonnière est présumée être une importante raison expliquant le fait que le bassin du cours inférieur du fleuve Mékong supporte des pêches continentales très productives et d’une grande biodiversité. Nous avons utilisé les rapports d’isotopes stables du C et du N d’échantillons de tissus pour estimer les sources de production primaire qui supportent la biomasse de poissons dans le Mékong et trois grands affluents au Cambodge. -

Learning More About the Ganga River Basin's Golden Mahseer Fish To
© John Brown Learning more about the Ganga river basin’s golden mahseer fish to better protect it India is home to 15 of the world’s approximately 47 species of mahseer, freshwater fish from the Cyprinidae family, which Read this case study also includes carp and tench.1 The name mahseer roughly Contact the WWF-India team translates as ‘mahi’ (fish) and ‘sher’ (tiger), hence it being known as the tiger of the river.2 The golden mahseer (Tor putitora) is listed as ‘endangered’ on the IUCN Red List.3 The golden mahseer is the mahseer species on which WWF-India is primarily focusing its conservation efforts, due to the species’ conservation status as well as its declining population trends. Golden mahseer typically live in fast-moving, relatively cold waters, inhabiting hill streams with a rocky and stony substrate, although they’ve also successfully adapted to Map of the Ganga river basin introduction in lakes and reservoirs. The golden mahseer is found in the Himalayan foothills, the Indus, Ganga and Brahmaputra basins as well as in the south of India. Most of India’s golden mahseer are found in Uttarakhand state, where it is the official state fish. The mahseer can grow to a large size, 1 A tiger among fish: the Ganga’s golden mahseer up to 275cm and 54kg, and can live over 17 years; due to its size, appearance and behaviour, the mahseer is particularly prized by sports fishers, and has been since the time of British rule.4 The golden mahseer’s lifecycle is intimately connected with the river’s flow: adult fish inhabit foothill rivers and migrate upstream in monsoon conditions to reach suitable spawning grounds; as such, the fish’s survival is dependent on the A view of the Kolu river near preservation of habitat connectivity and adequate flows. -
