Book Description

A global assessment of the current state of freshwater fish biodiversity and the opportunities and challenges to conservation.




Threatened Freshwater Animals of Tropical East Asia


Book Description

This book offers a comprehensive account of the current state of inland waters in tropical and subtropical East Asia, exploring a series of case studies of freshwater fish, reptiles, amphibians, birds, mammals and water bodies at particular risk. The book highlights the rich freshwater biodiversity of tropical East Asia and draws attention to the various threats it faces due to human activities and rapid environmental change. It addresses the question of whether the contributions of these animals and habitats, or biodiversity in general, to ecosystem functioning and service provision provide sufficient basis for arguments supporting nature conservation. Drawing on instances from the rivers and lakes of tropical East Asia, the book also asks whether the benefits accruing from intact ecosystems are likely to be enough to ensure their preservation. If the answer to either or both these questions is ‘no’, then what are the prospects for freshwater biodiversity in rapidly changing tropical East Asia? This book will be of interest to students and scholars of biodiversity, conservation, freshwater ecology, ecosystem services and Asian Studies.







Freshwater Biodiversity


Book Description

Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.










A review of the inland fisheries of India


Book Description

India has abundant water resources including rivers, canals, ponds, lakes, reservoirs, upland lakes, and floodplain wetlands covering over 5. [Author]8 percent of the country. [Author] These environments harbour a rich fish fauna of 1 035 species that constitutes the basis for the inland fisheries sector, which annually produces 2 144 452 tonnes of fish – if enhanced and culture-based fisheries are included – corresponding to 21 percent of total fish production. [Author] Rivers like the Ganga, Brahmaputra, and Barak, alongside floodplain wetlands, play crucial roles, especially in the east and northeast. [Author] Lakes are abundant in upland areas. [Author] Reservoirs cover over 1 percent of India's land and hold untapped potential for fisheries development. [Author] Traditionally, fishing in inland water bodies has been a small-scale or subsistence activity. [Author] Fishing practices, crafts and gear used in inland fisheries are still traditional. [Author] Cooperative societies are present in reservoirs and wetlands giving fishers better bargaining power with traders and better prices for the fish. [Author] Inland fisheries are imperative for poverty alleviation, food security, gender empowerment, cultural services, ecosystem function, and biodiversity, and are important for achieving the Sustainable Development Goals. [Author] Important threats to inland fisheries include water scarcity, habitat loss, pollution, climate change and invasive species. [Author] However, several major river conservation programmes have been initiated. [Author] The collection of inland fishery catch statistics remains weak and production appears to be significantly under-reported in many states. [Author] A simplified method for defining water bodies and estimating catch is proposed and all States have been advised to follow the same definition for water bodies. [Author]
