Abstract The paper demonstrates the applicability of fluorescent microparticles (FMP) for the determination of cladoceran feeding rates. For this purpose we examined the relation between filtering rate, ingestion rate, gut passage time and body length of Daphnia pulex at different food concentrations in laboratory experiments, and diurnal changes of filtering rates of Daphnia longispina in in situ experiments, using FMPs as tracer particles. Good agreement of our results with published data based on cell counts and radiotracer methods proves the suitability of the FMP-method. Potentials and limitations of the method are discussed.
