Book Description
Aquaculture is the practice of cultivating aquatic animals and plants in managed aquatic environments. Aquaculture in salt-water or marine environments is called mariculture. Fish culture, or pisciculture, refers to the husbandry of finfish. The most popular aquaculture species are finfish grown in fresh waters, accounting for over 40 percent of total aquaculture production. Aquaculture has a long history, but for much of the world it remains somewhat of a novelty, being practiced less than agriculture or capture fisheries. During the last 30 years of the twentieth century, aquaculture grew at an average annual rate of 10 percent, and emerged as the only growth sector of the fisheries industry. At the beginning of the twenty-first century, aquaculture's share of total fish production worldwide was 25 percent, and that proportion is projected to increase. Even though the production of fish from capture fisheries has not substantially increased over the past decade, capture fisheries nevertheless account for a far greater percentage than aquaculture. Aquaculture is practiced for a number of reasons, chief among them being food production and income generation. Most fresh-water aquaculture production (over 70 percent) comes from low-income, food-deficit countries. Even in the poorest countries, fish farming is seldom solely a subsistence activity. So while farmers may consume some of their product, typically fish are sold, thereby enabling farmers to earn income to purchase other goods and services. Aquaculture has two types, freshwater aquaculture and salt-water aquaculture. With the ever increasing demand of fish and increased fish catching activities, sea is facing shortage of fish and cannot fulfil this much demand. Freshwater aquaculture has also improved economies of many areas by providing new job opportunities. The fish produced there is mostly used by industries for processing which is then made available as canned food item.Handbook on Freshwater Aquaculture is the ultimate guide to freshwater aquaculture, an essential resource for both professional aquaculturists and backyard fish growers.

Book Description
This comprehensive publication “Handbook on Freshwater Aquaculture” is the collective effort of a wide array of eminent people associated with Indian aquaculture. Special emphasis has been given to aquaculture and its prospects and problems in rural India especially the lesser known areas. The book covers almost all important aspects of freshwater aquaculture, both traditional and modern aquaculture techniques, water quality issues, integrated farming practices, environmental, socio-economic and livelihood issues. It is expected that the book will prove to a source of useful information for the needs of students, scholars, farmers and researchers.

Book Description
The revised third edition is a comprehensive and better illustrated book covering the major aspects of freshwater aquaculture within Asiatic region with particular focus on the Indian context. In the present revised edition, an attempt has been made not only to update the information but also three additional chapters such as Biotechnology in Aquaculture, Fisheries Extension Education and Ornamental Fish Production and Management are incorporated for the graduate and postgraduate students in the subject concerned. Hope this book would facilitate the teaching of the subject in Colleges and Universities as per their syllabi.

Book Description
"Freshwater Aquaculture" is the definitive guide to freshwater aquaculture, an indispensable resource for both professional aquaculturists and backyard fish growers. William McLarney, scientist and pioneer in the field, describes every aspect of aquaculture, from the underlying scientific concepts to stepby- step instructions for each type, size, and phase of culture. Numerous species are discussed in detail, from catfish and trout to freshwater shrimp and clams. The emphasis throughout is on energy efficiency and ways to work profitably within natural ecosystems. Using numerous tables, hints, and details of how and how not to do it, McLarney proves fish culture need not be hit or miss, with endless trial and error, financial losses, and discouragement to the prospective farmer. Nothing has been overlooked in this guide. As well as providing all the basic information on the culture of North American freshwater food fishes, the author has explained the various aquaculture systems, including those integrated with plants, land animals, and cage cultures. Pond construction and repair, water quality and chemistry, marketing and shipping concerns, diseases, and legal restrictions are all explored. "Freshwater Aquaculture" includes cooking methods for the different species as well as a large appendix describing qualities such as habitat, ease of culture, and flavor of the thirty-five food fishes discussed. A thorough resource section provides valuable information on publications, supplies, advice, and training.

Book Description
Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.
