Book Description
Ocean harvests have plateaued worldwide and many important commercial stocks have been depleted. This has caused great concern among scientists, fishery managers, the fishing community, and the public. This book evaluates the major models used for estimating the size and structure of marine fish populations (stock assessments) and changes in populations over time. It demonstrates how problems that may occur in fisheries dataâ€"for example underreporting or changes in the likelihood that fish can be caught with a given type of gearâ€"can seriously degrade the quality of stock assessments. The volume makes recommendations for means to improve stock assessments and their use in fishery management.

Book Description
This important and informative new book outlines and discusses details of the basic principles and methods that are central to any study of fish condition, from a fish ecology and fisheries biology perspective. Condition and Health Indicators of Exploited Marine Fishes describes the potential capacities of condition indicators, providing examples showing the use of these indicators to solve practical problems in connection with fish ecology and fisheries research. By focusing on wild fish populations, the book complements the increasing number of scientific works that are contributing to show how fish condition studies are key to reveal problems in marine aquaculture, the effects of pollution, fish disease, and the importance of fish in human nutrition and medicine. Condition and Health Indicators of Exploited Marine Fishes provides a comprehensive introduction to the study of fish condition that will assist advanced undergraduate and postgraduate students, researchers and professionals, working in marine ecology and biology, fisheries biology, environmental sciences and fish pathology. All universities and research establishments where biological and environmental sciences, fisheries and aquaculture are studied and taught should have copies of this book on their shelves.

Book Description
Fisheries are in a state of crisis throughout the world. While there has been some success, truly effective fisheries management seems beyond our grasp. The knowledge needed for proper management contains a broad array of facts and connections from statistical stock assessments, to the information that allows government agencies to track compliance with rules and beyond.This book describes the state-of-the-art knowledge about fishery systems. Seldom seen in a scientific publication regarding fisheries science, this book presents a multidisciplinary perspective of fisheries management. Leading fisheries scholars with backgrounds in biology, ecology, economics and sociology ask how management institutions can learn and put their lessons to use. The Knowledge Base for Fisheries Management offers a unique overview of the world of fisheries management and provides the background to draw conclusions of what is needed to improve management.Covering a wide range of regimes, case studies and professional perspectives, this publication will be an obliged reference to anyone involved on fisheries management, assessment, policy making or fisheries development all over the world. * The only book on the market that analyzes fisheries in a biological, sociological and economic way* Fills a gap, focusing not only on the production of knowledge for fisheries management but also on how it is used in all steps of the management system and the decision making processes * Focuses on the hot topic: scientific knowledge and society-science based policies * Documents disseminated research from many different management systems, both European and world wide

Book Description
This is the ninth volume of ten in the The Natural History of the Crustacea Series. The chapters in this volume synthesize the diverse topics in fisheries and aquaculture. In the first part of the book, chapters explore worldwide crustacean fisheries. This section comes to a conclusion with two chapters on harvested crustaceans that are usually not within the focus of the mainstream fisheries research, possibly because they are caught by local fishing communities in small-scale operations and sold locally as subsistence activity. In the second part of the book, the authors explore the variety of cultured crustacean species, like shrimps, prawns, lobsters, and crabs. Chapters in the third part of the volume focus on important challenges and opportunities, including diseases and parasitism, the use of crustacean as bioindicators, and their role in biotechnology.
