Regular reporting and monitoring of fishery and aquaculture production using genetic information, i.e. using information on stocks, breeds, monosex groups, polyploids, products of modern biotechnology and hybrids, would allow aquaculturists to assess which breeds or strains could be most useful for production, and help fishery managers better manage and trace products from capture fisheries. Genetic information would be useful to both aquaculturists and fishery managers in assessing which stocks are under threat or endangered and in traceability requirements for the origin and handling of aquatic food products. However, the capacity and information requirements for incorporating genetic information into national and global statistics are significant and, in many cases, currently prohibitive. A key source of information for this paper was the reports currently being submitted to the FAO Fisheries and Aquaculture Department by countries as part of the process to produce the first report on The State of the World’s Aquatic Genetic Resources for Food and Agriculture (SoW AqGR). Through this country-driven process, FAO is receiving information on stocks, varieties, strains and other farmed types that are currently being used in aquaculture and fisheries or that are being actively researched for future use. The country reports will further attempt to include relevant policies and constraints relating to the collection and monitoring of genetic data.

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

Atlantic Salmon is a cultural icon throughout its North Atlantic range; it is the focus of probably the World’s highest profile recreational fishery and is the basis for one of the World’s largest aquaculture industries. Despite this, many wild stocks of salmon are in decline and underpinning this is a dearth of information on the nature and extent of population structuring and adaptive population differentiation, and its implications for species conservation. This important new book will go a long way to rectify this situation by providing a thorough review of the genetics of Atlantic salmon. Sponsored by the European Union and the Atlantic Salmon Trust, this book comprises the work of an international team of scientists, carefully integrated and edited to provide a landmark book of vital interest to all those working with Atlantic salmon.

Intraspecific differences in erythrocyte antigens (blood types) were shown to occur in four species of Pacific salmon, the sockeye or red salmon (Oncorhynchus nerka), the chinook or king salmon (O. tshawytscha), the chum salmon (O. keta), and the pink salmon (O. gorbuscha). Antisalmon-erythrocyte sera prepared in rabbits and chickens were used after absorption of species-specific antibodies. Some of these blood types were shown to differ in their frequency of occurrence between different geographic races. In addition, isoimmunizations were prepared and at least eight different patterns of antigenic composition were displayed by the cells tested. These results indicate that considerable antigenic diversity exists in salmon. Reagents to detect valuable markers for the investigation of geographic races of salmon should be obtained through further research.

The joint management of Norway and Russia in the Barents Sea has been successful in conserving the living marine resources and is a major factor contributing to the present rich fisheries in the area. The basis for this conservation success is scientific research, which, to a large extent, has been conducted through a long-lasting co-operation between Russian and Norwegian scientists that has expanded greatly over the past half century. Based on joint Russian-Norwegian authorships, this monumental book celebrates the scientific co-operation by reflecting on the historical development and the scientific methods applied, and by offering a comprehensive presentation of the vast knowledge of the Barents Sea resources and ecosystem obtained through these co-operative efforts.
