Figure 6.2. Biomass of 0-group fish species in the Barents Sea, August–October 1980–2022. The biomass of 0-group fishes for the period 1980-1992 were estimated based on abundance indices and mean fish weight, while for later years it is ased on fish biomass. Indices were calculated in SAS for the period 1980-2017 and in R since that. Biomasses in 2018, 2020 and 2022 were corrected for lack of coverage.
