The conservation, sustainable use and development of aquatic genetic resources (AqGR) is critical to the future supply of fish. The State of the World’s Aquatic Genetic Resources for Food and Agriculture is the first ever global assessment of these resources, with the scope of this first Report being limited to cultured AqGR and their wild relatives, within national jurisdiction. The Report draws on 92 reports from FAO member countries and five specially commissioned thematic background studies. The reporting countries are responsible for 96 percent of global aquaculture production. The Report sets the context with a review of the state of world’s aquaculture and fisheries and includes overviews of the uses and exchanges of AqGR, the drivers and trends impacting AqGR and the extent of ex situ and in situ conservation efforts. The Report also investigates the roles of stakeholders in AqGR and the levels of activity in research, education, training and extension, and reviews national policies and the levels of regional and international cooperation on AqGR. Finally, needs and challenges are assessed in the context of the findings from the data collected from the countries. The Report represents a snapshot of the present status of AqGR and forms a valuable technical reference document, particularly where it presents standardized key terminology and concepts.

Recent advances in molecular genetics and genomics have been embraced by many in natural resource conservation. Today, several major conservation and management journals are now using 'genetics' editors to deal solely with the influx of manuscripts that employ molecular data. The editors have attempted to synthesize some of the major uses of molecular markers in natural resource management in a book targeted not only at scientists but also at individuals actively making conservation and management decisions. To that end, the text features contributors who are major figures in molecular ecology and evolution - many having published books of their own. The aim is to direct and distil the thoughts of these outstanding scientists by compiling compelling case histories in molecular ecology as they apply to natural resource management.

Fish and shellfish comprise annually nearly 70-million tons of the world's edible animal protein. However, because of this demand, previously vast stocks have often been exhausted to the point of near extinction. The first book of its kind in the area of freshwater/marine biodiversity, this extensive work reviews the present status of genetic resource management, its needs and constraints, various intervening human factors such as pollution and overfishing, and problems posed by different species and life-styles. This discussion of the conservation of fish and shellfish resources is illustrated by four diverse groups: Atlantic salmon, cupped oysters, common and Chinese carp, and Nile tilapia. These results, produced by the collaboration of nine leading population and production geneticists, aquaculturists, and behavioral and developmental ecologists should become a fundamental resource useful to biologists, scientists and advisors exploring current issues in the fishery sciences. - Four page color plate section - Database of key organizations for contact purposes - Foreword by Dr. Mike Strauss, Am. Assoc. for the Advancement of Science; and Dr. Peter Day, Rutgers University - Four in-depth case studies by international experts - Editors are major names in marine/freshwater fisheries science - Originally sponsored and reviewed by U.S. National Academy of Sciences

Fish Conservation offers, for the first time in a single volume, a readable reference with a global approach to marine and freshwater fish diversity and fishery resource issues. Gene Helfman brings together available knowledge on the decline and restoration of freshwater and marine fishes, providing ecologically sound answers to biodiversity declines as well as to fishery management problems at the subsistence, recreational, and commercial levels. Written in an engaging and accessible style, the book: considers the value of preserving aquatic biodiversity offers an overview of imperiled fishes on a taxonomic and geographic basis presents a synthesis of common characteristics of imperiled fishes and their habitats details anthropogenic causes of decline examines human exploitation issues addresses ethical questions surrounding exploitation of fishes The final chapter integrates topics and evaluates prospects for arresting declines, emphasizing the application of evolutionary and ecological principles in light of projected trends. Throughout, Helfman provides examples, explores case studies, and synthesizes available information from a broad taxonomic, habitat, and geographic range. Fish Conservation summarizes the current state of knowledge about the degradation and restoration of diversity among fishes and the productivity of fishery resources, pointing out areas where progress has been made and where more needs to be done. Solutions focus on the application of ecological knowledge to solving practical problems, recognizing that effective biodiversity conservation depends on meeting human needs through management that focuses on long term sustainability and an ecosystem perspective.

Genetic sciences have produced a 'blue revolution' in the way we use aquatic biodiversity. By 2020 the world will be eating more farmed than wild fish, marine bacteria may yield the cure for cancer and deep-sea bacteria may be exploited to gobble up oil spills.

As the human population increases and nations become more industrialized, the habitat and water quality required for the survival of fish continues to decline. In addition to these environmental factors, fish populations are directly or potentially affected by harvesting, enhancement programs and introgression with hatchery-propagated or transgenic fish. To our knowledge no other scientific meeting has been assembled to consider the breadth of the problem, to review the technology that is presently available for the preservation of the germ plasm of salmonid stocks and to identify the scientific advances that are required to overcome the problems. Because many salmonids have spawning grounds within the confines of a specific region or county but will spend a large portion of their life cycle within the territorial waters of other countries or in the open ocean, the preservation of unique genes or gene pools in these animals requires international cooperation. This scientific meeting has provided a forum in which to discuss the problems, evaluate the present methods or technology for addressing the problems and suggest new directions or innovations that need to be implemented. During this meeting we limited our discussion to salmonid fishes. However, the general conclusions about the factors that affect the population dynamics of fish stocks and the technical aspects concerning the preservation of germ plasm will be applicable to other fish species.
