Abstract

Produced and eliminated biomass ofBosmina longirostris in the River Danube (Hungary) was estimated in 1982. An attempt was made to calculate the rate of immigration and mortality, taking into consideration the hydrological characteristics of the river. Production and immigration influence population change to about the same extent.
