Broodstock Management And Egg And Larval Quality

At present, the supply of eggs and fry is one of the major constraints on future aquaculture development. For the majority of farmed species, production is totally dependent on harvesting of broodstocks or seed from wild populations At present we know little about the control of reproduction of most farmed finfish nor of the detailed nutrient, metabolic and husbandry requirements of the broodstock or the ways in which they might be managed to optimize seed production and improve the quality of eggs and larvae. Newer technologies such as ploidy and gender manipulation, induced spawning and cryopreservation are coming to the forefront of modern broodstock management and all of these topics are considered, in detail, in this new text. Broodstock Management and Egg and Larval Quality has been written as a standard text for commercial practitioners and students of aquaculture, fish biology and fisheries and provides a comprehensive review of current and future methods of broodstock and hatchery management. The range of marine and freshwater tropical and temperate finfish species considered, together with contributions from many of the world's most eminent fish biologists, provide comprehensive and international coverage of this increasingly important area of aquaculture.

The successful development of coastal aquaculture in the opening years of the new millennium will depend upon solution of a multiplicity of economic, sociological, engineering, scientific and environmental issues. The objective of this volume is to update the current status of research in aquaculture in the coastal zone and outline directions for the development of sustainable aquaculture using modern methodologies. It also discusses the application of existing knowledge and the creation of new knowledge to ensure that aquaculture will develop at a sufficient pace to sustain and enhance the availability of high quality foods of aquatic origin in the human diet despite the global decline in the capture fishery.

The large amount of information on fish reproduction available is not always readily accessible to all interested parties. Written to appeal to aquaculturalists, conservation managers, and scientific researchers, Methods in Reproductive Aquaculture provides an overview of available techniques and addresses ways to improve depleted stocks of endange

A comprehensive and authoritative synthesis on the successful production of fish larvae Success Factors for Fish Larval Production is a vital resource that includes the most current understanding of larval biology, in the context of larval production. The text covers topics such as how external (environmental and nutritional) and internal (molecular/ developmental/ physiological/ behavioral/ genetic) factors interact in defining the phenotype and quality of fish larvae and juveniles. The expert contributors review broodstock genetics and husbandry, water quality, larval nutrition and feeding, growth physiology, health, metamorphosis, underlying molecular mechanisms, including epigenetics, for development, larval behavior and environmental conditions. Compiled by members of a European Union-funded consortium of top researchers, Success Factors for Fish Larval Production provides a wide-range of authoritative information for the aquaculture industry and academia. In addition to a wealth of information, the authors review research and commercially applicable larval quality indicators and predictors. The successful production of good-quality fish larvae is of vital importance for fish farming and stock enhancement of wild fisheries: Includes contributions from a consortium of noted researchers and experts in the field Deals with on how to improve egg quality and larval production via broodstock management and nutrition Suggests ways to control the phenotype of juveniles and table-size fish via manipulations of the conditions of larval rearing (e.g., epigenetics) Includes ideas for optimizing diet composition, formulation, and technology Integrates knowledge and practical experience in order to help advancing excellence in aquaculture Success Factors for Fish Larval Production offers fish biologists, developmental biologists, physiologists and zoologists the most current and reliable information on the topic. All those working in fish aquaculture facilities and hatcheries in particular will find great interest to their commercial operations within this book.

With the continuing decline of commercial stocks of wild-caught fish, the interest in the culture of cold-water marine fish is rapidly growing, with much ongoing research into the development of this area. This important and timely book reviews the current and potential future situation concerning the major exploited marine fish species, such as cod, haddock, hake, wolf-fish, halibut, turbot and sole. The editors of Culture of Cold-Water Marine Fish have drawn together and carefully edited chapters from a wide range of international scientists. The contents list includes detailed reviews of abiotic factors, microbial interactions, prophylaxis and disease, live food and first feeding technologies, brood stock and egg production, functional development, weaning and nursery, on-growing to market size, status and perspectives for the species covered, stock enhancement and sea ranching, and an analysis of the finances, economics and markets for the fish species used in marine aquaculture. Culture of Cold-Water Marine Fish is an essential purchase for personnel involved in marine aquaculture, whether managing fish farms, supplying equipment and feed to the industry, or researching, studying or teaching the subject. Marine biologists, fisheries scientists, fish biologists, ecologists and environmental scientists will all find much of use and interest in this timely book. Libraries in all universities and research establishments where these subjects are studied and taught should have copies.

The successful reproduction of cultured brood stock is essential to the sustainable aquaculture of aquatic organisms. This book describes recent advances in the field of finfish reproductive biotechnology. The chapters in this volume are written by eminent scientists who review the progress and assess the status of biotechnology research that is applicable to the reproduction of finfish species for aquaculture. A wide range of topics is included starting with broodstock technologies such as broodstock genetics, broodstock nutrition, environmental control of maturation and impacts of stress on broodstock, gametes and progeny. The volume includes technologies for induction of ovulation and spermiation using synthetic hypothalamic peptides. Gamete technologies which are described include cryopreservation, chromosome set manipulation, disease prevention and control for gametes and embryos and the development of transgenic fish with enhanced production characteristics. Genetic and endocrine technologies for the production of monosex male and female fish stocks are also described. The closing chapter summarizes the discussion of each topic at the workshop, provides recommendations to industry and describes priorities of research and development. Researchers as well as teaching faculty in the aquaculture field will find this volume of great value.
