Synopsis Effects of Trawling and Dredging on Seafloor Habitat by : National Research Council
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.

Synopsis Ecosystem Effects of Fishing in the Mediterranean by : Sergi Tudela
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.

Synopsis Impacts of Trawling and Scallop Dredging on Benthic Habitats and Communities by : Svein Løkkeborg
This publication examines recent experimental studies of the impact of towed fishing gears, such as trawls and scallop dredges, on benthic habitats and communities (organisms that live at or near the bottom of the sea). The review gives a critical evaluation of the methodological limitations of impact studies, given the complexity and natural variability of benthic communities.
