The diversity (species composition and their relative abundance) within the assessed trophic guilds (primary and secondary producers) in the International North Sea is not harmed by anthropogenic stresses. Indicator(s) and (reference): FW5 Changes in phyto- and zooplankton (OSPAR) Thresholds: Not anticipated, assessment by trend analysis linked to pressures (OSPAR)

The balance between the total densities of assessed trophic guilds (phytoplankton, zooplankton, fish) in the International North Sea is not impaired by anthropogenic stresses. Indicator(s) and (reference): FW5 Changes in phyto- and zooplankton (OSPAR). Thresholds: Not anticipated, assessment by trend analysis linked to pressure factors (OSPAR) FW7 Fish biomass and abundance of food guilds (OSPAR) No threshold, trends (OSPAR)

The size distribution of specimens across the assessed trophic guild (demersal sub-apex predators) of the International North Sea is not impaired by anthropogenic stresses. Indicator(s) and (reference): FC2 Share of large fish (OSPAR): Thresholds: 0.17 (LFI) (OSPAR) FC3 Mean maximum length of fish (OSPAR): No threshold, trend (OSPAR) FW3 Size composition in fish community (OSPAR): No threshold, trend (OSPAR)

The productivity of the assessed trophic guild (primary producers) is not negatively affected by anthropogenic pressure factors. Indicator(s) and (reference): FW2 Production of phytoplankton (OSPAR): No threshold, trend (OSPAR)
