Figure 4 : Estimated Spawning Stock Biomass (SSB) for some of the most important fish stocks in the Norwegian EEZ for the time-period 1988-2024 (ICES 2024b). Total biomass decreased during the period 2017-2020, but since then continued to increase at a steady rate. From 2023 to 2024 the biomass of Northeast Atlantic mackerel (Scomber scombrus), blue whiting (Micromesistius poutassou ) and NSS herring (Clupea harengus) in the Northeast Atlantic all decreased. Total biomass is estimated to constitute short of 13 million tons in 2024.
