General Information

The monitoring of zooplankton covers abundance, biomass and species composition and concerns the water column habitats.

Sub-programme: Zooplankton species composition, abundance and biomass

The aim of monitoring zooplankton is to assess the state of the Baltic Sea for the pelagic habitats where zooplankton form a link between the primary producers and fish.

This sub-programme covers three parameters: Species abundance (numbers or cover), Species abundance (biomass) and Species present (whole community or selected species only). It covers the whole Baltic Sea area.

The species composition, age distribution, abundance and biomass are used to calculate HELCOM core indicator ‘Zooplankton Mean Size and Total Abundance‘.
