Fishing activity in the Barents Sea is tracked by the Vessel Monitoring System (VMS). Figures 184.108.40.206 and 220.127.116.11 show fishing activity in 2017-2020 based on Russian and Norwegian data. VMS data offer valuable information about temporal and spatial changes in fishing activity.
Anthropogenic impact: Fishing activity
The most widespread gear used in the Barents Sea is bottom trawl; but longlines, gillnets, Danish seines, and handlines are also used in demersal fisheries. Pelagic fisheries use purse-seines and pelagic trawls. The shrimp fishery used special bottom trawls.

From 2011 onwards, minimum mesh size for bottom-trawl fisheries for cod and haddock is 130 mm for the entire Barents Sea; previously the minimum mesh size was 135 mm in the Norwegian EEZ and 125 mm in the Russian EEZ. It is still mandatory to use sorting grids. Minimum legal catch size was harmonized at the same time: for cod from 47 cm (Norway) and 42 cm (Russia) to 44 cm for all, and for haddock from 44 cm (Norway) and 39 cm (Russia) to 40 cm for all.
