| dc.description | Concerns about the impact of towed fishing gears such as trawls and dredges on benthic habitats and organisms have increased over the last two decades. This publication reviews the most recent experimental studies of the impact of towed fishing gears on benthic communities. Otter trawls, beam trawls and scallop dredges are likely to have different physical impacts on the sea bed owing to their different catching principles. The most noticeable physical effect of otter trawling is the furrow crea ted by the doors. Beam trawling and scallop dredging cause a flattening of irregular bottom topography by eliminating natural features. The long term effect of fishing activities have not been investigated, but several studies provide clear evidence of short term effects. The difficulty in conducting impact studies that produce clear conclusions results mainly from the complexity and natural variability of benthic communities. | |
