Figure 5.3.1.4. Estimated total biomass of krill in the Barents Sea in August-October 1980-2023 based on pelagic night trawl catches covering the upper water layers (0-60 m). Estimates in 1980-2001 were calculated based on average night catches of all night stations and total surveyed area. Estimates in 2003-2022 were calculated based on an subarea average night catches and covered area within the subarea (Fig. 5.3.1.1). Estimates for 2002 are missing due to mistakes with the weight of krill. In 2023, one catch makes a big difference in estimates: total biomass with this catch (red star) and without blue line are shown.
