OverviewConcerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout marine waters. This title describes how the assessment of fishing 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 on various types of habitat. These studies indicate that low mobility, long-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 colour maps of fishing effort for all regions with significant bottom trawl or dredge fisheries.
