Zooplankton

In zooplankton countings mostly rotifers, cladoceras and copepods are counted. The result is an abundance (pcs/l or pcs/m3), which can be converted into biomass (mg/l or mg/m3). Knowledge of zooplankton density, size and of the different species helps to understand zooplankton’s role in aquatic environment and it’s ability to control phytoplankton.
