Abstract:

Seasonal changes of food consumption rate of planktivorous fish (vendace, smelt and bleak) in two lakes with significantly different fish density, were compared with seasonal changes of (1) elimination of planktonic crustacean biomass, (2) mortality, (3) age structure in crustacean populations and (4) mean body weight of crustaceans. It was found that factors other than fish predation must be responsible for the seasonal and spatial changes of crustacean populations. This has been also confirmed by the results of an extensive analysis of zooplankton communities in 30 lakes with fish predation of varied intensity.
