Sturgeons are considered “living fossils”, sharing many morphological and biological features with ancestral fish. Furthermore, sturgeons are of the utmost interest from an economic perspective, not only for the caviar but for the flesh. However, the wild populations of the majority of the species are at serious risk of extinction all over the world. So, it is urgent to develop strategies for both farming culture and conservation and recovery in natural habitats. This book provides a comprehensive view of the biology and sustainable development of sturgeons putting emphasis on the Southern Europe autochthonous species such as Acipenser nacarii and Acipenser sturio that share geographical distribution. Other relevant species (such as Huso huso, A. oxyrhinchus, A. ruthenus, A. stellatus) and areas (Germany, Russia, North America) are also considered. The contents are organised in three sections: Taxonomy and Biogeography (including the morphological and genetic analyses that clarify the taxonomy and phylogeny of sturgeons, focused on those from Southern Europe), Biology and Aquaculture (where several aspects of the developmental biology, feeding, and reproduction are considered in relation to the improvement of sturgeon farming), and Recovery and Conservation (that collates and analyses different recovery research actions, the ecology of the rivers for restoration as well as the problems related to the trade of caviar).

A one-of-a-kind book for researchers interested in finfish nutrition Handbook of Nutrient Requirements of Finfish provides a summary of qualitative and quantitative nutrient requirements for almost all cultured finfish for which a significant amount of nutritional information now exists. Information is presented by species and includes how each species is cultured, an index of production, regional locations where each species is being cultured, examples of purified or test diets and special conditions required for laboratory studies, nutrient requirements and practical diet formulation. Discussions of special diets and feeding practices are included for certain species. This book will be a useful guide for students, researchers, practicing nutritionists, aquaculturists, and feed manufacturers interested in fish nutrition.

Current growth in global aquaculture is paralleled by an equally significant increase in companies involved in aquafeed manufacture. Latest information has identified over 1,200 such companies, not including those organizations in production of a variety of other materials, i. e. , vitamins, minerals, and therapeutics, all used in varying degrees in proper feed formulation. Aquaculture industries raising particular economically valued species, i. e. , penaeid shrimps and salmonids, are making major demands on feed ingredients, while relatively new industries, such as til apia farming, portent a significant acceleration in demand for properly formulated aquafeeds by the end of the present decade and into the next century. As requirements for aquafeeds increases, shortages are anticipated in various ingredients, especially widely used proteinaceous resources such as fish meal. A variety of other proteinaceous commodities are being considered as partial or complete replacement for fish meal, especially use of plant protein sources such as soybean meal. In the past five years, vegetable protein meal production has increased 10% while fish meal production has dropped over 50%, since 1989, largely attributed to overfishing and serious decline in wild stock. Throughout fisheries processing industries, traditional concepts as "waste" have given way to more prudent approaches, emphasizing total by-product recovery. Feed costs are a major consideration in aquaculture where in some groups, i. e. , salmonids, high protein-containing feeds using quality fish meal, can account for as much as 40 to 60% of production costs.

Modern North American sturgeons and paddlefish are the result of 100 million years of evolution. Once an integral part of aboriginal culture, their numbers were decimated by overfishing and habitat destruction during the past two centuries. This book details the extensive science aimed at helping these remarkable species recover from the brink of extinction, and describes the historical, biological, and ecological importance of North American sturgeon and paddlefish. The text is enhanced by photographs and detailed line drawings. This comprehensive volume will be an invaluable resource for researchers, educators, and consultants, in academic and government settings, who work to further scientific understanding of these fishes. No other single compilation has documented current information in such detail.
