To conclude on the total impact of trawling, an extensive mapping of fishing effort and bottom habitat would be necessary. In general, the response of benthic organisms to disturbance differs with substrate, depth, gear, and type of organism. Seabed characteristics of the Barents Sea are scarcely known and the lack of high-resolution maps of benthic habitats and biota is currently the most serious impediment to effective protection of vulnerable habitats from fishing activities.
