Advocacy, fuelled by concerns about overfishing, has played an important role in the origins of MPA policy (Caveen et al., 2013, 2015). { bidder: 'criteo', params: { networkId: 7100, publisherSubId: 'cdo_mpuslot' }}, syncDelay: 3000 if(!isPlusPopupShown()) Bottom trawling a fishing technique in which the ocean floor is literally scraped by heavy nets to cause confusion and lore fish into the net . },{ Such effects may account for notable increases in the dominance of flatfish in both tropical and temperate systems.

Trawls are fishing nets that are pulled along the bottom of the sea or in midwater at a specified depth. Planning for the designation of marine protected areas (MPAs) and their associated management therefore impinges on fisheries more significantly than on any other marine use. { bidder: 'onemobile', params: { dcn: '8a969411017171829a5c82bb4deb000b', pos: 'cdo_rightslot_flex' }}, { bidder: 'openx', params: { unit: '539971065', delDomain: 'idm-d.openx.net' }}, { bidder: 'criteo', params: { networkId: 7100, publisherSubId: 'cdo_btmslot' }}, { bidder: 'openx', params: { unit: '539971080', delDomain: 'idm-d.openx.net' }}, On side trawlers, the trawl is set and hauled over the side with power winches or manually by a large crew. 3. a.
