Effects of Trawling and Dredging on Seafloor Habitat

Jeremy Collie, Professor of Oceanography, University of Rhode Island, Narragansett, and Member, Committee on Ecosystem Effects of Fishing: Phase 1 -- Effects of Bottom Trawling on Seafloor Habitats, Ocean Studies Board, Division on Earth and Life Studies, The National Academies
At the request of the National Marine Fisheries Service, this new report from the National Research Council looks at the effects of bottom trawling and dredging on seafloor habitats.
Specifically, the report summarizes and evaluates existing knowledge on the effects of bottom trawling on the structure of seafloor habitats and the abundance, productivity, and diversity of bottom-dwelling species in relation to gear type and trawling method, frequency of trawling, bottom type, species, and other important characteristics. It examines knowledge about changes in seafloor habitats associated with trawling and the cessation of trawling. It summarizes and evaluates research on the indirect effects of bottom trawling on non-seafloor species and recommends how existing information could be used more effectively in managing trawl fisheries. Finally, the report recommends research needed to improve understanding of the effects of bottom trawling on seafloor habitats.
These briefings were for members of Congress and congressional staff only. The report was publicly released on March 18, 2002 and can be found, in its entirety, on the Web site of the National Academies Press.
