Book Description
This book serves as an advanced text on fisheries and fishery population dynamics and as a reference for fisheries scientists. It provides a thorough treatment of contemporary topics in quantitative fisheries science and emphasizes the link between biology and theory by explaining the assumptions inherent in the quantitative methods. The analytical methods are accessible to a wide range of biologists, and the book includes numerous examples. The book is unique in covering such advanced topics as optimal harvesting, migratory stocks, age-structured models, and size models.

Book Description
The Global Atlas of Marine Fisheries is the first and only book to provide accurate, country-by-country fishery catch data. This groundbreaking information has been gathered from independent sources by the world's foremost fisheries experts. Edited by Daniel Pauly and Dirk Zeller of the Sea Around Us Project, the Atlas includes one-page reports on 273 countries and their territories, plus fourteen topical global chapters. Each national report describes the current state of the country's fishery; the policies, politics, and social factors affecting it; and potential solutions. The global chapters address cross-cutting issues, from the economics of fisheries to the impacts of mariculture. Extensive maps and graphics offer attractive and accessible visual representations.

Book Description
In 1989 we were asked by Dr Vidar Wespestad (National Oceanographic and Atmospheric Administration. National Marine Fisheries Service. Alaska Fisheries Science Center. Seattle. USA) to prepare and convene a session at the 1992 World Fisheries Congress in Athens. Greece on computer appli cations in fisheries. We agreed that the idea was a good one and the computer session turned out to be very successful. The computer session was organized in three parts: training classes. informal demonstrations accompanied by posters. and oral presentations of scientific papers. We were both amazed by the high level of interest and the high quality of contributions presented at the paper session. Returning from the World Fisheries Congress. we suggested to the International Council for the Exploration of the Sea (ICES) in Copenhagen to hold a theme session on the topic 'Computers in Fisheries Research' at their statutory meeting the fol lowing year in Dublin. Ireland. The proposal was very positively received by ICES and we began organizing this new meeting with Dr John Ramster of the Ministry of Agriculture. Fisheries and Food. Fisheries Laboratory. Lowestoft. England. Based on our experience with the World Fisheries Congress. we expected a maximum of 15 titles would be submitted to the ICES theme session. Accordingly. the ICES symposium was originally allo cated one half-day time slot. The response we received from the call for papers. however. exceeded our most optimistic expectations. A total of 62 abstracts were submitted. Consequently.

Book Description
The workshop referred closely to the results of a first workshop held in Bangkok in 2002 (The International Workshop on Factors Contributing to Unsustainability and Overexploitation in Fisheries) but aimed more specifically at answering the following three major questions: What are the major obstacles to the implementation of major legal instruments? What are the main lessons learned and the possible paths to solutions for improved implementation? What are the possible gaps that may exist in these instruments to guide the international community in improving the management of marine fisheries? The workshop was based on a review of eleven case studies, each relating to one of the following categories of fishery: large volume small pelagics; tuna and tuna-like species; large volume demersals; and coastal fisheries. This publication contains the report of the Workshop, discussion papers containing case studies and notes submitted by participants. The document, and in particular the conclusions adopted by workshop participants, will serve as a basis for further analytical work aimed at improved fisheries management and a more effective implementation of major international fisheries instruments.

Book Description
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.
