Aquaculture And Conservation Of Inland Coldwater Fishes

This book provides the latest information on trans-Himalayan Hindu Kush Region (HKR) fisheries including the Indian Himalayan Region (IHR) as well as the historical context of its sustainable development for improving livelihood and nutritional security. The book serves as an important document to provide knowledge and information about the major concerns of environmental and anthropogenic factors that have impacted the population of certain important fishes in the ecosystem and the strategies and policies required for the conservation of these important groups of fishes, viz., Mahseer, snow trout, minor carp, catfishes, etc. The chapters describe the information to the readers on potential cold water and cool water fish species suitable for large-scale farming and propagation addressing the issues of diseases, nutrigenomics, and nanobiotechnology. This book also addresses the prospects and potential of recreational fishing in India and the scope for its improvement to generate more employment and income citing the success stories and primary information from reputed anglers. Finally, the book also elucidates a comprehensive yet representative description of many challenges associated with inland coldwater- cool water fisheries and aquaculture in HKR, IHR, and its way forward.

The trans-Himalayan region covers the countries of the Himalayas, Karakoram and in Hindu Kush and Pamir. Fisheries play an important role in providing food and income to the mountain people. This volume contains papers presented at a meeting, held in July 2001 in Nepal, to review information, experiences and findings related to fish and fisheries in the region, including fish species distribution, fishing intensity, socio-economic conditions and livelihoods of fisher communities, as well as to the impacts of environment degradation, conservation measures and aquaculture technologies on indigenous and exotic cold water fish.

"The book covers fishery assessments, habitat and community manipulations, and common practices for managing stream, river, lake, and anadromous fisheries. Chapters on history; ecosystem management; management processes; communications with the public; introduced, undesirable, and endangered species; and the legal and regulatory frameworks provide the context for modern fisheries management."

The thirteen papers presented in this publication review fish stocks and fisheries of mountainous areas of Asia: Himalayas (Bhutan, Nepal, northern states of India within the Himalayas), Western Ghats (India), Karakoram-Hindu Kush (Pakistan, Afghanistan), Pamir (Tajikistan), Tien Shan (Kyrgyzstan, Kazakhstan), Altai (Kazakhstan, Mongolia, China), high altitude lakes of Mongolia and those of western China (provinces of Qinghai and Xinjiang [Uighur Autonomous Region] and Xizang [Tibet Autonomous Region]) and Caucasus (Armenia, Georgia, Azerbaijan). From south to north, fish fauna complexes change from Oriental to Palaearctic. Cool and coldwater streams and rivers support subsistence and/or recreational/sport fisheries, with commercial fisheries practised only in some lakes and reservoirs. While fishing of streams and rivers is largely unmanaged, considerable management effort has gone into some lakes and reservoirs, especially in Kazakhstan, Kyrgyzstan and India in order to maintain reasonably high fish catches. The management measures have included translocation and stocking of exotic fish species and regulation of fisheries. For recreational fishery, brown trout has been stocked in rivers and streams of the southern slopes of Himalayas, rainbow trout in some streams of Western Ghats ... etc.

This book is a rich resource of important information on coldwater fish farming and coldwater fisheries management, including new research and recent technological advances. It aims to provide an understanding of the underlying mechanisms of coldwater physiology of fishes, which is essential for effective fishery management and for taking advantage of their vast potential application in aquaculture. Coldwater Fisheries and Aquaculture Management: Technology for Sustainable Food Production elaborates on key aspects associated with reproductive biology and endocrinology of coldwater fishes, such as gonadal development and maturation, vitellogenesis, steroidogenesis, whole genome information of fishes, transcriptomics, proteomics, and more. It also looks at genetic modification of coldwater fishes, phytobiotic-based feed to attain profitability in aquaculture, and the nutritional requirements of coldwater fishes, such as plant-based proteins in fish diets and feeding carbohydrates to fish. It also describes the beneficial dietary nutrition of fish consumption by humans. Several chapters address the various challenges to coldwater fish and fishery management, such as fish bacterial diseases (along with their immune components and defense mechanisms), unpredictable nature of climate change on fish, water pollution, etc. The volume also offers strategies on the sustainable management of fish that include looking at pollution in freshwater ecosystems, biotechnological interventions, predicting threats to fish from climate change, and other factors. This volume will be of value to those in fishery management and fish science as well as to marine researchers, faculty and students, and other involved with aquaculture science and management.

This report discusses the need and methodologies for the utilization and conservation of genetic resources of aquatic animals. More than a review of genetic principles and technologies, the report addresses the application of such principles and technologies in development and conservation projects and research. Specific recommendations are made with regard to the genetic resources contained in natural populations, fisheries stocks, and aquaculture. Recommendations concerning regulatory, policy and legal aspects of aquatic genetic resources are also presented.
