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.
Commencing with chapters covering genetic variation and how it
can be measured, the authors then look at genetic structure in
natural populations, followed by a new chapter covering genetics in
relation to population size and conservation issues. Genetic
variation of traits and triploids and the manipulation of ploidy
are fully covered, and another new chapter is included, entitled
'From Genetics to Genomics'. The book concludes with a chapter
covering the impact of genetic engineering in aquaculture.
With the inclusion of a wealth of up-to-date information, new
text and figures and the inclusion of a third author, Pierre
Boudry, the second edition of Biotechnology and Genetics in
Fisheries and Aquaculture provides an excellent text and
reference of great value and use to upper level students and
professionals working across fish biology, aquatic sciences,
fisheries, aquaculture, genetics and biotechnology. Libraries in
all universities and research establishments where biological
sciences, fisheries and aquaculture are studied and taught should
have several copies of this excellent new edition on their
shelves.
* Completely updated, revised and expanded new edition
* Subject area of ever increasing importance
* Expanded authorship
* Commercially useful information for fish breeders

Klappentext
The use of genetic and biotechnological techniques in fisheries and aquaculture has expanded massively since the publication of the successful and popular first edition of this book in 2003.
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.
