Following the structure of the first edition, this carefully revised and updated new edition includes much new information of vital importance to those working in the fisheries and aquaculture industries. As well as the inclusion of a new chapter covering the emerging fields of genomics, transcriptomics, proteomics and metabolomics, this exciting new edition provides much new and enhanced information on all major areas of importance in this field, including the following: conservation genetics, forensic applications, identification of animals to family level, genome mapping, disease identification, the use of triploidy in reducing the genetic impact of escapees, and the use of GMOs in the industry. With so much new information included, the addition of a further well known and respected co-author and many new better quality illustrations, this second edition of Biotechnology and Genetics in Fisheries and Aquaculture will be of great use as a reference to upper level students studying fisheries, aquaculture, genetics, biotechnology, aquatic and biological sciences. Personnel working in the fish farming and fisheries industries management and research sectors will find much of use and commercial interest in this important book. All libraries in universities and research establishments where biological sciences, aquaculture and fisheries are studied and taught should have copies of this excellent new edition on their shelves. Zusammenfassung Following the extremely well-received structure of the first edition, this carefully revised and updated new edition now includes much new information of vital importance to those working and researching in the fisheries and aquaculture industries.
