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.

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.

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.

Concerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout the marine waters of the United States. Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Many experimental studies have documented acute, gear-specific effects of trawling and dredging on various types of habitat. These studies indicate that low mobility, long-lived species are more vulnerable to towed fishing gear than short-lived species in areas where the seabed is often disturbed by natural phenomena. Trawling and dredging may also change the composition and productivity of fish communities dependent on seafloor habitats for food and refuge. The scale of these impacts depends on the level of fishing effort. This volume presents color maps of fishing effort for all regions with significant bottom trawl or dredge fisheries-the first time that such data has been assembled and analyzed for the entire nation.
