Code: FZP
Site types that use this protocol: Lakes

The crustacean zooplankton which dominate the open water of lakes form an important link in the food chain between phytoplankton and fish.  Most lakes contain a few species from a small number of genera but marked changes in species composition can occur when there is a progressive change in the trophic status.

Species presence and abundance are determined through fortnightly sampling at lake sites only.
