Total biomass

Zero group fish are important consumers on plankton and prey of other predators and therefore an important element in the transfer of energy between trophic levels in the ecosystem. The total biomass of 0-group (cod, haddock, herring, capelin, polar cod, and redfish), was 1.95 million tonnes in August-September 2016, which is slightly above the long-term mean of 1.76 million tonnes (Figure 3.5.1). The biomass was dominated by capelin and herring. Most of the biomass was distributed in the central and northern-central part of the Barents Sea.
