Trout Farming Handbook

Rainbow trout can be an excellent economic proposition for farming in temperate waters. The husbandry needed is simpler, and the fish take a year less than Atlantic salmon to grow to equivalent size. The fifth edition of this handbook covers the latest developments and new opportunities particularly for rainbow trout farming in the sea. The design and construction of trout farms is outlined and the following stages of trout production are dealt with in detail: hatching and fry production; fish feeds and feeding; hygiene and the prevention and treatment of disease; and the management of brood stock. Processing and marketing are discussed together with ways and means of increasing profitability. Special attention is given to the prevention of pollution and protection of the environment. The book provides not only a primer but a working manual for trout farmers in fresh and salt water, and is intended for the professional fish farmer and student of aquaculture.

Over the past few years, there has been significant growth and development in the salmon farming industry. In order to be successful, practitioners not only need to know how the salmon lives and survives in the wild but, amongst other things have knowledge of disease, production processes, economics and marketing. The Handbook of Salmon Farming is a practical guide that covers everything the practitioner needs to know, and will also be of great use to academics and students of aquaculture and fish biology. The editors have invited contributions from experts in academia, the fish industry and government to provide an up-to-date and comprehensive handbook.

Aquaculture is one of the fastest way to produce animal protein for growing population in the World. Aquaculture is the art, science, and business of producing aquatic plants and animals useful to humans. Fish farming is an ancient practice and date back as far as 2500 BC. In Europe, fish raised in ponds became a common source of food during the Middle Ages. Today, aquaculture plays a major role in global fish supply. Today, the global community faces financial and economic crisis, climatic changes and the pressing food and nutrition needs of a growing population with finite natural resources. As the world’s population continues to increase over the coming decades, and global living standards rise, demand for fish is set to keep on growing. With most wild capture fisheries already fully exploited, much of that new demand will have to be met from aquaculture. According to FAO estimates, more than 50 % of all fish for human consumption now comes from aquaculture. Aquaculture is one of the most resource-efficient ways to produce protein. Fish come out well because, in general, they convert more of the feed they eat into body mass than livestock animals. Salmon is the most feed-intensive farmed fish to convert feed to body weigt gain and protein followed by chicken. Aquaculture is the controlled cultivation and harvest of aquatic organisms. Most commonly grown are finfish and shellfish, but other aquatic organisms are also cultivated such as seaweed, microalgae, frogs, turtles, alligators, and endangered species. There are many similarities between aquaculture and agriculture, but there are some important differences as well. Aquaculture, like agriculture, is necessary to meet the food demands of a growing global population with diminishing natural fisheries stocks. Aquaculture and agriculture are both farming. However, aquaculture is farming in the water and therefore requires a different set of knowledge, skill, and technology.

Of all the species which have been introduced into fish farming, salmon and trout and, in particular, the Atlantic Salmon most clearly represent the outstanding achievements of modern, intensive aquaculture. The successful farming of these species stands testimony to the results of thorough research and development , major advances in technology, investment, and rigorous marketing. However, the very real dangers of uncontrolled and rapid expansion, unrestrained investment, and market saturation have also been revealed. This new handbook is designed as a benchmark reference to the many technical aspects of salmon and trout farming, the varied issues of growth and development, operational and administrative concerns, disease prevention and treatment and much, much more.
