Book Description
The fishery sector is important from Indian economy view point as it contributes a source of income to a number of fishermen and has huge export potential. The systems and technology used in aquaculture has developed rapidly in the last fifty years. They vary from very simple facilities like family ponds for domestic consumption in tropical countries to high technology systems like intensive closed systems for export production. Much of the technology used in aquaculture is relatively simple, often based on small modifications that improve the growth and survival rates of the target species. Nowadays, the fish and fisheries industry is one of the fastest growing international commodity markets globally. Guaranteeing an adequate supply to this international market requires hundreds of thousands of fishing vessels and fish farms, as well as tens of thousands of fish processing workers, wholesalers and retailers in countries spread all over the world. The fishery sector thus generates employment and income for millions of people and in one of the major fields to venture. A wide range of aspects of fresh water aquaculture such as selection of species of fish and shellfish, construction and preparation of various types of fish ponds, control of aquatic weeds and predators, production of seed fish and their transportation, fish nutrition and fish diseases and their control pertaining to composite fish culture, air breathing fish culture etc. have been dealt with a length for easy adoption. The major contents of the book are classification of fishes, general characters of fishes, techniques in fish identification, cold water fisheries of India, physical and chemical properties of fishery water, chemical constituents of fish, economic importance of fishes, fish in relation to human health, construction of fish farms, etc. In this book you can find all the basic information required on the fundamental aspects of the fisheries and aquaculture technology with detailed information of their applications a wide variety of industrial processes etc. The book is very useful for research scholars, technocrats, institutional libraries and entrepreneurs who want to enter into the field of aquaculture technology.

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]

Book Description
Sustainable water management, food security and water security being some of the most critical issues facing the world in the 21st century - dubbed the Century of Water : this monograph outlines various options for proactive management of fisheries and aquaculture to sustainably meet the growing food requirements of millions of people living in developing countries both in rural areas and in cities. Both freshwater and marine fisheries are covered. Besides giving production statistics calculated by various organisations, the book lists traditional as well as potentially promising newer organisms suitable for aquaculture in swamps, ponds, marshes, lakes and mangroves not only as a source of nutritious food but also as employment avenues for small-scale or marginal fisherfolk. The book can server as an introductory text for courses in fisheries and aquaculture both in traditional universities and in marine and freshwater institutes.
