├┐Aquaculture production systems in developing countries are largely based on the use of unimproved species and strains. As knowledge and experience are accumulated in relation to the management, feeding and animal health issues of such production systems, the availability of genetically more productive stock becomes imperative in order to more effectively use resources. For instance, there is little point in providing ideal water conditions and optimum feed quality to fish that do not have the potential to grow faster and to be harvested on time, providing a product of the desired quality. Refinements in the production system and improvement of the stock used must progress hand in hand. In this paper we deal separately with genetic and non-genetic issues pertaining to the multiplication and dissemination of improved strains. The separation is somewhat arbitrary, and as will be evident from our discussion, there is frequent interaction between the two.

The first edition of this unique book combined an outlining and updating of the traditional areas of fish processing technology with detailed descriptions of important new areas of work. This fully revised and updated edition continues to provide coverage of modern aspects of traditional processes, and highly practical descriptions of important new areas. All the chapters which have been kept from the first edition have been brought up-to-date, and there are four new chapters on: methods of identifying fish species; modified atmosphere packaging of fish; aspects of quality and HACCP in fish processing and temperature modeling in fish transportation.Written as an overview of the field for industrialists in developed countries wishing to improve or diversify their operation and for those teaching this aspect of food science and technology, the book is also of proven value to workers in developing countries which are expanding their fish processing industries to earn important foreign currency.

This publication stands out from many others on fish conservation in that it deals exclusively with freshwater fish of European waters. Thirty-four contributions offer up-to-date reviews on the conservation status of freshwater fish in ten European countries and research results in genetics, systematics and ecology of more than twenty endangered European fish taxa. Selected examples show the changes in the fish communities of whole catchment areas under human influence in the past decades. Not only scientists in fish biology, but also fishery managers and hydraulic engineers will find new insights into the biology of endangered fish species and basic data in order to elaborate specific conservation measures for the local survival of these taxa.

Aquaculture is now recognized as a viable and profitable enterprise worldwide. As aquaculture technology has evolved, the push toward higher yields and faster growth has involved the enhancement or replacement of natural foods with prepared diets. In many aquaculture operations today, feed accounts for more than one-half the variable operating cost. Therefore, knowledge of nutrition and practical feeding of fish is essential to successful aquaculture. This book is not written exclusively for scientists but also for students, practicing nutritionists, and aquaculturists. It covers the known nutrient requirements and deficiency effects for different fishes, and digestion and metabolism of nutrients and energy. It discusses nutrient sources and preparation of practical and research feeds. It gives directions for conducting fish nutrition and feeding experiments. Feeding practices for salmonids, channel catfish, tilapias, shrimps and hybrid striped bass are presented. Since the first edition of this book was printed, the National Research Council of the National Academy of Sciences has revised the nutrient requirements for fish. These revisions are in the present edition. Other additions to this revised edition are chapters on nutrition and fish health, and bioavailability of nutrients. Each original chapter has been meticulously revised and updated with new information. Aquaculture is a dynamic area and new technologies are being introduced continuously; therefore, some of the material discussed in this revised edition may become obsolete quickly. Nonetheless, the material presented has been thoughtfully selected and updated to make it of maximum use to persons whose interests range from general aquaculture to animal nutrition to feed manufacture.

16 pages of colour plates to aid identificationOnly published text available where all relevant material is referenced togtherThis manual enables the isolation and identification of bacteria that are found in aquatic animals (particularly fish). The emphasis is on bacteria from farmed aquatic animals (fish,molluscs and crustacea) but some attention is also given to other marine and freshwater animals such as mammals and birds, both captive (as in zoos) or wild, as well as aquarium fish.
