Figure A.26.3. Comparison of trend in average biomass density (kg/km2) of cod in the Arctic part of the Barents Sea with densities in the Sub-Arctic part and with total stock biomass estimates (from ICES). A) Ratio of the mean density (kg/km2) of cod in the Arctic vs. the Sub-Arctic part within the Norwegian sector of the Barents Sea, from BESS in August-September. All values are larger than 1, indicating overall higher densities of cod in the Arctic compared to the Sub-Arctic part. B) Mean biomass density (kg/km2) trends in Arctic (solid) and Sub-Arctic areas (stippled), from BESS in August-September. C) Total cod stock biomass estimates for the entire Barents Sea, from ICES.
