Abstract Measurements were made of the rates of grazing of the ostracod Cyprinotus carolinensis fed 14C-labelled filamentous blue-green algae (cyanobacteria). The grazing rate was a linear function of food concentration at densities below 1.1 µg dry weight of algae · ml-1 and independent of concentration at densities above 11.5 µg algae · ml-1. Starvation affected grazing rates significantly, but light vs. dark feeding, animal density, and the volume of feeding container did not. Grazing on Nostoc sp. was a linear function of ostracod size. Respiration of C. carolinensis and the blue-green algae was not a significant factor in the tests of grazing.
