This book was released on 2002-08-09 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2005 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

These include physical effects such as burial by dredge spoil and chemical effects from the release of contaminants. The final sections discuss safeguards to reduce the negative effects of dredging & dumping operations as well as the role of Fisheries & Oceans Canada in protecting fish & fish habitat.
