Most demersal fisheries in the ecoregion are bottom-trawl fisheries. Abrasion by towed bottom-contacting gear causes damage and loss of potentially important benthic habitat. Figure 6 maps the effort by bottom trawlers in the recent decade (2009–2019) for the main targeted species. Mapping of benthic habitats is currently limited. Preliminary data indicate a high degree of overlap between the trawl footprint for cod and redfish and the habitats of corals and sponges (Figure 7).
