The growth of worldwide aquaculture has been sustained and rapid, and the explosion of research in genetic biotechnology has made significant impact on aquaculture and fisheries, although potential for much greater progress exists. Aquaculture and Fisheries Biotechnology: Genetic Approaches covers topics essential to the study of fish genetics, including qualitative and quantitative traits, crossbreeding, inbreeding, genetic drift, hybridization, selection programs, polyploidy, genomics and cloning. This fully updated second edition also addresses environmental risk, food safety and government regulation of transgenic aquatic organisms, commercial applications of fish biotechnology and future issues in fish genetics.
