Currently 20,000-30,000 species of fish are identified in the diverse aquatic ecosystems globally, as a result in a freshwater ecosystem everyday new species are including by the researchers in the area of Ichthyology diversity. Generally, 24000 fish species listed scientifically in the global scenario, in that, nearer to 11% are available in Indian aquatic environment. Among them, 2200 species so far recorded, 3.32% belongs to the cold freshwater ecosystem, 24.73% belongs to the warm fresh waters bodies, 6.50% belongs to the brackish waters and 65.45% belongs to the ocean system. In that, the fish biodiversity of the Karnataka shares the richness of species around 240, in Cauvery river belt of Southern Karnataka share around 109 species, in Krishna river belt of Northern share around 168 species, in Kali river belt of Western Karnataka share 124 species and Karnaja river belt of Eastern Karnataka share 59 species of fishes distributed as a 102 genera, 38 families and 14 orders covering whole Karnataka fish diversity. Among these total fish species, 3 orders dominating with diverse species richness by the composition of Cypriniformes covering 5 families, 45 genera and 140 species, whereas order Siluriformes covering 9 families, 24 genera and 51 species and in Perciformes covering 9 families, 15 genera and 26 species. It has been also recognized as around 40 species under the list of threatened, 5 species are critically endangered, 22 species are endangered and 13 are vulnerable as per the red data book. As conservation strategies, researchers were involved with selective breeding method to enrich the native fish species and it may help to reduce or mitigate the problem of fish species diversity in Karnataka.

Biodiversity is declining at an alarming rate due to anthropogenic activities around the world. This book is the first volume in the new series Biodiversity Hotspots of the World, which highlights the 36 hotspot regions of the world, regions that were designated as reaping maximum benefit from preservation efforts. This series is our humble attempt to document these hotspots as a conservation and preservation measure. This first volume in the series focuses on the Western Ghats and Sri Lanka, construed as forming a community of species because of their shared biogeographical history. The volume explores the diversity and conservation efforts of the extraordinarily rich species found here, including plants, many of which are found nowhere else in the world; forests, which face tremendous population pressure and have been dramatically impacted by demands for timber and agricultural land; as well as the hotspot’s diverse mammals, birds, insects, and amphibian species, and more. The volumes in this series will be essential resources for researchers and practitioners in the fields of conservation biology, ecology, and evolution.

Biodiversity Conservation - Challenges for the Future is a multidisciplinary book, linking topics on biodiversity, conservation, food and nutrition, organic farming, food security and sustainable management. The book summarizes the key ideas for meeting the challenges of biodiversity conservation. It presents suggestions and recommendations and reiterates the need for raising awareness among a range of stakeholders about conservation and sustainable management of biological resources and associated traditional knowledge resources along with ensuring appropriate capacity building at individual and institutional levels. The book also brings a wealth of knowledge about the local marine ecosystem and Western Ghats biodiversity. Readers will find an a overview of several aspects of biodiversity ranging from: a) The diversity of flora and fauna which will be of immense benefit to the local community. b) Laws and regulations related to access and benefits of sharing Bio-resources.(please check if the yellow highlighted term is correct) c) Sustainable management models for marine and wetland environmental conservation. d) Case studies of human participation in biodiversity conservation programmes. e) Key ideas for meeting the challenges of biodiversity conservation and for planning conservation programmes. Biodiversity Conservation - Challenges for the Future is a handy resource for the local conservationist community consisting of policy makers, academicians, scientists, environmentalists, students and grass root level conservationists.

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]
