This important book contains a great wealth of practical
information on trout and salmon, species of fish that are of huge
scientific and commercial interest.
The introductory chapters of Trout and Salmon cover the biology
and environmental variables of importance when considering these
species. Further chapters encompass current information on the
ecology of salmon and trout, with particular emphasis on the
definition and quantification, where possible, of their
environmental requirements and limitations. Comprehensive coverage
of the impacts of human activities on trout and salmon is included,
together with important aspects of relevance when considering
issues of species conservation and habitat restoration.
The book concentrates on the two species of the genus Salmo with
many references and comparisons with the genus Oncorhynchus.
Conclusions drawn within the book apply to both genera and as such
the book will have relevance for both Europe and North America as
well as other areas where these genera occur.
Trevor Crisp has written a book that will be of great interest
and use to fish biologists and fisheries scientists, to aquatic
biologists, conservationists, ecologists and environmental
scientists. The book will be particularly valuable for those
working in government environment agencies and fish and wildlife
departments and to all those involved in the management of these
important species, their fisheries and habitats.
