Accounting for nearly half, 45%, of the world's food fish including fish, crustaceans, molluscs, and amphibians, aquaculture is currently one of today's fastest growing production sectors. Aquaculture Microbiology and Biotechnology examines the advances and research in genetic manipulation and biotechnology that provide the foundation and fuel for this rapid growth. It discusses commonly used methods such as chromosome manipulation and hormone treatment and the application of these techniques to produce triploid, tetraploid, haploid, gynogenetic and androgenetic fish.
