• Sommario/riassunto: The recent development of molecular biology and genetic techniques, in particular those that are increasingly being used in practical situations in fish biology, fisheries and aquaculture, has led to a gap in the understanding by many of the science behind these techniques and their correct implementation for maximum results. The authors of this important book, Andy Beaumont and Kate Hoare, have written a text of great clarity, which carefully explains the science and application of molecular and genetic techniques to fisheries and aquaculture situations and what these new technologies h
