The microcomputer revolution and the imperative to improve fishery management have accelerated the pace of technological innovation and the application of new technologies to practical fishery management problems. This volume was developed from a symposium held in February 2000, at which scientists working in all oceans of the planet presented research results from diverse marine species and habitats. The proceedings contain the results of research intended to define critical habitat, to monitor behaviour and physiology, and to synthesize tracking results into population models.

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.

The 2nd international tagging and tracking symposium was held in San Sebastian, Spain, in October 2007, seven years after the first symposium was held in Hawaii in 2000 (Sibert and Nielsen 2001). In the intervening seven years, there have been major advances in both the capability and reliability of electronic tags and analytical approaches for geolocation of tagged animals in marine habitats. Advances such as increased data storage capacity, sensor development, and tag miniaturization have allowed researchers to track a much wider array of marine animals, not just large and charismatic species. Importantly, data returned by these tags are now being used in population analyses and movement simulations that can be directly utilized in stock assessments and other management applications.Papers in this volume are divided into three sections, the first describing insights into behavior achieved using acoustic, archival, and novel tags, the second reporting on advances in methods of geolocation, while the final section includes contributions where tag data have been used in management of marine species. Accurate documentation of animal movements and behaviors in critical marine habitats are impossible to obtain with other technologies. The management and conservation of marine species are critical in today’s changing ocean environment and as electronic tags become more accurate and functional for a diversity of organisms their application continues to grow, setting new standards in science and technology.

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.

The microcomputer revolution and the imperative to improve fishery management have accelerated the pace of technological innovation and the application of new technologies to practical fishery management problems. This volume was developed from a symposium held in February 2000, at which scientists working in all oceans of the planet presented research results from diverse marine species and habitats. The proceedings contain the results of research intended to define critical habitat, to monitor behaviour and physiology, and to synthesize tracking results into population models. This is the first synthesis of tagging and tracking methods used on marine fish and documents the state of the art of modern electronic tagging and tracking techniques. It will be the standard reference in this field for years to come and will be consulted by researchers planning to use these techniques in the future. Seasoned researchers as well as beginning graduate students will find this volume indispensable.

The papers in this volume cover exciting developments in new tagging applications in marine animals. This includes new analyses of geolocation techniques using remote tags and new documentation of animal behaviour in marine habitats.
