Reproductive Biotechnology in Finfish Aquaculture

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.
