Book Description
This report summarizes talks, discussions and conclusions from a multi-disciplinary workshop on genetic consequences of fisheries and fisheries management held in Rönne, Bornholm in October 2006. The workshop was intended for fishermen, scientists, decision makers, managers and other stakeholders from the Nordic countries. The main objectives were to improve communication between parties involved in fisheries management present current knowledge regarding genetic consequences of fisheries, and highlight the importance of including genetic/biological data in the management of exploited fish species agree upon recommendations on how genetic considerations could be implemented in management and decision making processes.

Book Description
The collapse of many of the World’s fisheries continues to be of major concern and the enhancement of fish stocks through techniques such as ranching is of huge importance and interest across the globe. This important book, which contains fully peer reviewed and carefully edited papers from the 2nd International Symposium in Stock Enhancement and Sea Ranching is broadly divided into sections covering the following areas: The present situation of stock enhancement Seed quality and techniques for effective stocking Health management of hatchery stocks Methods for evaluating stocking effectiveness Population management in stock enhancement and sea ranching Management of stocked populations Ecological interactions with wild stocks Genetic management of hatchery and wild stocks Socio-economics of stock enhancement Case studies Stock Enhancement and Sea Ranching has been written and edited by some of the world’s foremost authorities in fisheries science and related areas and is essential reading for all fisheries scientists throughout the World. Fish biologists, marine and aquatic scientists, environmental biologists, ecologists, conservationists, aquaculture personnel and oceanographers will all find much of use and interest within this book. All libraries within universities and research establishments where these subjects are studied and taught should have copies of this book on their shelves.

Book Description
Since the first publication of "Population Genetics and Fishery Management" in 1987, significant technological, analytical, and conceptual changes have occurred. By explaining basic population genetics in a fisheries context, the text continues to serve as an excellent starting point for approaching complex recent developments.

Book Description
Fisheries genetics researchers will find invaluable the thirty-eight peer-reviewed contributions in this book, presented at the 20th Lowell Wakefield Fisheries Symposium "Genetics of Subpolar Fish and Invertebrates," held in May 2002 in Juneau, Alaska. Looming over concerns of lost fisheries stocks and persistent erosion of genetic variability are predictions of global warming, which may further tax genetic resources. One consequence is an increased reliance on genetic applications to many aspects of fisheries management, aquaculture, and conservation. The contributions in this book are important to modern fisheries science and genetics, and illustrate the evolution of the field over the past decade. The improved technology provides tools to address increasingly complicated problems in traditional applications and ecological and behavioral studies. The union between molecular and quantitative genetics, where many of the major questions about population structure and evolution remain unanswered, will also benefit from the new technologies.

Book Description
The basic principle of all molecular genetic methods is to employ inherited, discrete and stable markers to identify genotypes that characterize individuals, populations or species. Such genetic data can provide information ori the levels and distribution of genetic variability in relation to mating patterns, life history, population size, migration and environment. Although molecular tools have long been employed to address various questions in fisheries biology and management, their contributions to the field are sometimes unclear, and often controversial. Much of the initial impetus for the deployment of molecular markers arose from the desire to assess fish stock structure based on various interpretations of the stock concept. Although such studies have met with varying success, they continue to provide an impetus for the development of increasingly sensitive population discriminators, yielding information that can be valuable for both sustainable exploitation and the conservation of fish populations. In the last major synthesis of the subject, Ryman and Utter (1987) summarized progress and applications, though this was prior to the wide-scale adoption of DNA methodology. New sources of genetic markers and protocols are now available, in particular those that exploit the widely distributed and highly variable repeat sequences of DNA, and the amplification technique of the polymerase chain reaction.

Book Description
The impact of man on the biosphere is profound. Quite apart from our capacity to destroy natural ecosystems and to drive species to extinction, we mould the evolution of the survivors by the selection pressures we apply to them. This has implications for the continued health of our natural biological resources and for the way in which we seek to optimise yield from those resources. Of these biological resources, fish stocks are particularly important to mankind as a source of protein. On a global basis, fish stocks provide the major source of protein for human consumption from natural ecosystems, amounting to some seventy million tonnes in 1970. Although fisheries management has been extensively developed over the last century, it has not hitherto considered the evolutionary consequences of fishing activity. While this omission may not have been serious in the past, the ever increasing intensity of exploitation and the deteriorating health of fish stocks has generated an urgent need for a better understanding of evolution driven by harvesting and the implications of this for fish stock management. The foundations for this understanding for the most part come from recent developments in evolutionary biology and are not generally available to fisheries scientists. The purpose of this book is to provide this basis in a form that is both accessible and relevant to fisheries biology.
