Over-exploitation of the world's fish resources receives considerable attention and is a source of justifiable concern. However, fishing does much more than simply remove the species of interest. What are the other problems that fishing might cause? Are there knock-on effects caused by removal of the target species for other parts of the system? What incidental damage does fishing cause and how much do we really know and understand about the consequences of our actions? The Effects of Fishing on Marine Ecosystems and Communitites draws together, within one volume, an expert and comprehensive assessment of the problem.

Most of the major impacts of fishing on the ecosystems recorded around the world occur in the Mediterranean. This variety of interactions is due to four main interrelated factors: the wide range of fishing gear and practices; very intensive fishing; a high diversity of exploited habitats, ranging from shallow water to the deep-sea and oceanic domain; and high biological diversity.

Fishing is a major form of ecological disturbance to marine communities throughout the world. In the past, fisheries biologists have concentrated on the studying of the direct effects of fishing on stocks of target species and understanding the processes of recruitment. There is now a growing appreciation of the ecological implications of the wider effects of fishing activities on marine organisms and their habitats. Contributions include articles that consider the physical effects of fishing gears on the seabed; distribution of, and trends in fishing effort; ecological effects on benthic fauna; long-term community changes; the effects of food subsidies in the marine environment; interactions between fisheries and marine mammals; technical measures to reduce impacts of fisheries; conservation issues and priorities; socio-economic implications of wider fisheries impacts.

The impact of pollution on fisheries and the potential health implications of eating contaminated fish are areas of considerable concern for the fishing and aquaculture communities, government bodies and the general public. Pollution, as well as over fishing, may well be contributory to recent serious declines in global fish stocks. Effects of Pollution on Fish brings together the work of many international experts each of whom have examined the literature on marine and freshwater fish and, where appropriate, invertebrates, to produce comprehensive chapters covering all major aspects of the impacts of pollution on fish and fisheries. The book describes these impacts in detail, from the molecular and sub-cellular level, through organism to population and community levels, and subsequently to socio-economic implications. The editors of this thorough and timely book have drawn together contributions encompassing molecular genetics, biochemistry, physiology, population and community biology, and fishery economics. As such, this important book will be of great use and interest to students and professionals studying and teaching in all those subject areas. Fish biologists, environmental scientists and ecotoxicologists, marine and freshwater ecologists, fisheries managers, aquaculture personnel and fish farmers, as well as fish veterinarians will all find much of great value within this book. Libraries in universities and research establishments concerned with these areas should all have copies of this book on their shelves.

Recent scientific literature has raised many concerns about whether fisheries have caused more extensive changes to marine populations and ecosystems than previously realized or predicted. In many cases, stocks have been exploited far beyond management targets, and new analyses indicate that fishing has harmed other species—including marine mammals, seabirds, sea turtles, and sea grasses—either directly through catch or habitat damage, or indirectly through changes in food-web interactions. At the request of the National Oceanic and Atmospheric Administration, the National Research Council conducted an independent study to weigh the collective evidence for fishery-induced changes to marine ecosystems and the implications of the findings for U.S. fisheries management. Dynamic Changes in Marine Ecosystems provides comprehensive information in regard to these findings.

Reef ecosystems extend throughout the tropics. Exploited by small-scale fishers, reefs supply food for millions of people, but, worldwide, there are growing worries about the productivity and current state of these ecosystems. Reef fish stocks display many features of fisheries elsewhere. However, habitat spatial complexity, biological diversity within and among species, ecosystem intricacy and variable means of exploitation make it hard to predict sustainable modes and levels of fishing.

This topical and exciting textbook describes fisheries exploitation, biology, conservation and management, and reflects many recent and important changes in fisheries science. These include growing concerns about the environmental impacts of fisheries, the role of ecological interactions in determining population dynamics, and the incorporation of uncertainty and precautionary principles into management advice. The book draws upon examples from tropical, temperate and polar environments, and provides readers with a broad understanding of the biological, economic and social aspects of fisheries ecology and the interplay between them. As well as covering 'classical' fisheries science, the book focuses on contemporary issues such as industrial fishing, poverty and conflict in fishing communities, marine reserves, the effects of fishing on coral reefs and by-catches of mammals, seabirds and reptiles. The book is primarily written for students of fisheries science and marine ecology, but should also appeal to practicing fisheries scientists and those interested in conservation and the impacts of humans on the marine environment. particularly useful are the modelling chapters which explain the difficult maths involved in a user-friendly manner describes fisheries exploitation, conservation and management in tropical, temperate and polar environments broad coverage of 'clasical' fisheries science emphasis on new approaches to fisheries science and the ecosystem effects of fishing examples based on the latest research and drawn from authors' international experience comprehensively referenced throughout extensively illustrated with photographs and line drawings
