Description: Currently the supply of eggs and fry is one of the most important constraints on future aquacultural developments. For many farmed species, production is totally dependent on harvests of broodstocks or seed from wild populations. Little is known about the control of reproduction of most farmed finfish nor of the detailed nutrient, metabolic and husbandry requirements of the broodstock or the ways that they might be managed to optimise seed production and improve the quality of the eggs and larvae. Newer technologies such as ploidy and gender manipulation, induced spawning and cryopreservation are increasingly being used to manage broodstocks and to minimise the risks of disease transfer with seed. All of these subjects are considered in this text, which has been written as a standard textbook for commercial practitioners and students of aquaculture, fish biology and fisheries, providing a comprehensive review of current and future methods of broodstock and hatchery management. The range of marine and freshwater and tropical and temperate finfish species considered, together with contributions from many of the best-known fish biologists in the world, provide a comprehensive and international treatment of a most important subject.
