During the past years, the molecular biology of fish has been intensively investigated in all aspects of fisheries, including diseases, genetics, nutrition, and ecology. The book covers comprehensive information relevant to the central theme of fish biology and aims to bring together an overall picture of the research in progress and to provide international communication among researchers in many disciplines with a common interest in the biology of fish. Coverage can include articles on any field of fish biology where the emphasis is placed on adaptation, function or exploitation in the whole organism.
