Críticas An extremely valuable book... [W]e believe this to be a very important text for fisheries ecology and management.--Reviews in Fish Biolgy and Fisheries Reseña del editor Quantitative modeling methods have become a central tool in the management of harvested fish populations. This book examines how these modeling methods work why they sometimes fail and how they might be improved by incorporating larger ecological interactions. Fisheries Ecology and Management provides a broad introduction to the concepts and quantitative models needed to successfully manage fisheries. Walters and Martell develop models that account for key ecological dynamics such as trophic interactions food webs multi-species dynamics risk-avoidance behavior habitat selection and density-dependence. They treat fisheries policy development as a two-stage process first identifying strategies for varying harvest in relation to changes in abundance then finding ways to implement such strategies in terms of monitoring and regulatory procedures. This book provides a general framework for developing assessment models in terms of state-observation dynamics hypotheses and points out that most fisheries assessment failures have been due to inappropriate observation model hypotheses rather than faulty models for ecological dynamics. Intended as a text in upper division and graduate classes on fisheries assessment and management this useful guide will also be widely read by ecologists and fisheries scientists. Contraportada This book is the next major contribution to the field of fisheries science. Walters and Martell provide fresh and non-intuitive perspectives on a variety of issues. Their merciless slaughtering of cherished sacred cows is supported by sound scholarship and cogent well-reasoned arguments. This will become a landmark work.--Jeffrey Hutchings Dalhousie University Biografía del autor Carl J. Walters is Professor at the Fisheries Centre at University of British Columbia.
