Grazing and food size selection by crustacean zooplankton compared to production of bacteria and phytoplankton in a shallow Norwegian mountain lake

Knut Yngve Børsheim and Sissel Andersen

Department of Microbiology and Plant Physiology, University of Bergen Allegt 70, 5000 Bergen, Norway

Received on May 1, 1986; accepted on October 1, 1986 Food size selection by suspension-feeding crustaceans in a shallow mountain lake was investigated with radiolabelled algae and bacteria, and with a series of monodisperse fluorescent latex beads with diameters ranging from 0.25 to 5.18 µm. Juvenile Daphnia longispina was a more efficient grazer on bacteria-sized particles than adults. Bosmina longispina and Cyclops scutifer were both able to ingest bacteria-sized food particles. The crustaceans harvested {small tilde} 100% of the primary production during the day investigated, but only 20% of the bacterial production. To keep the bacterial biomass in or near steady state, the microzooplankton must be harvesting most of the bacterial production.
