Book excerpt: From reviews of the hardback edition:- No matter how experienced a salmon man the reader is, I cannot believe he will study this extremely informative book without learning a great deal and gaining much enjoyment from doing so.The biology and life of the salmon . . .are all dealt with in a most interesting manner . . .Highly recommended. A book not to be read just once, but often to be consulted.; This book is dedicated to Salar the Salmon and what a tribute it is to this unique fish.

Available in PDF, EPUB and Kindle. Book excerpt: At present fishing for salmon in Norwegian home water is carried out with drift nets, bag nets, bend nets, lift nets and stake nets in the sea, and mainly by rods in the rivers. Catch statistics have been collected since 1876, but reliability of the statistics is questionable. The rates of exploitation on many Norwegian salmon stocks are very high, and data are presented and discussed for River Laerdal, River Eira and River Imsa stocks. As a result of this heavy exploitation with nets, the frequency of net-marked salmon entering rivers is high especially for griIse, although most net-marked salmon are only slightly damaged. It is suggested that mortality of salmon that are net-damaged hear or in brackish water is relatively small compared with salmon that escape from nets on the high seas. Some possible effects of selective fishing are also discussed. 159 Status of Exploitation of Atlantic Salmon in Norway REFERENCES Anon. (l985a) Salmon and sea trout fisheries 1984.

Download or read book Essential Fish Biology written by Derek Burton and published by Oxford University Press. This book was released on 2018 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: Essential Fish Biology provides an introductory overview of the functional biology of fish and how this may be affected by the widely contrasting habitat conditions within the aquatic environment. It describes the recent advances in comparative animal physiology which have greatly influenced our understanding of fish function as well as generating questions that have yet to be resolved. Fish taxa represent the largest number of vertebrates,with over 25,000 extant species. However, much of our knowledge, apart from taxonomy and habitat descriptions, has been based on relatively few of them, usually those which live in fresh water and/or are ofcommercial interest. Unfortunately there has also been a tendency to base our interpretation of fish physiology on that of mammalian systems, as well as to rely on a few type species of fish. This accessible textbook will redress the balance by using examples of fish from a wide range of species and habitats, emphasizing diversity as well as recognizing shared attributes with other vertebrates.

Available in PDF, EPUB and Kindle. Book excerpt: Stock Identification Methods, 2e, continues to provide a comprehensive review of the various disciplines used to study the population structure of fishery resources. It represents the worldwide experience and perspectives of experts on each method, assembled through a working group of the International Council for the Exploration of the Sea. The book is organized to foster interdisciplinary analyses and conclusions about stock structure, a crucial topic for fishery science and management. Technological advances have promoted the development of stock identification methods in many directions, resulting in a confusing variety of approaches. Based on central tenets of population biology and management needs, this valuable resource offers a unified framework for understanding stock structure by promoting an understanding of the relative merits and sensitivities of each approach. - Describes 18 distinct approaches to stock identification grouped into sections on life history traits, environmental signals, genetic analyses, and applied marks - Features experts' reviews of benchmark case studies, general protocols, and the strengths and weaknesses of each identification method - Reviews statistical techniques for exploring stock patterns, testing for differences among putative stocks, stock discrimination, and stock composition analysis - Focuses on the challenges of interpreting data and managing mixed-stock fisheries
