Barents Sea ecoregion

Pressure: Abrasion

Vessel monitoring system (VMS)-based maps show that the most widespread gears used in the central Barents Sea are bottom trawl and lines. Bottom trawling produces abrasion on the seafloor.

​​​​​​​​​Using VMS and logbook data it has been estimated that mobile bottom trawling techniques used by commercial fisheries in the 12 m+ vessel category have been deployed over approximately 35000 km2 of the Barents Sea in 2013, corresponding to ca. 1.6% of the ecoregion’s spatial extent.​ The proportion of swept seafloor increased by ca. 1% from 2009 until 2013. The pressure is mainly concentrated close to the coastline and in the central Barents Sea.
