Abstract
The filtering rates of14C labelledChlamydomonas sp. by 3 dominant species of rotifers were studied in eutrophic Lake Aydat. They varied from 4 to 53 µl ind−1 h−1 forKeratella cochlearis, from 2 to 56 µl.−1h−1 forKeratella quadrata and from 3 to 52 µl ind−1 h−1 forKellicottia longispina. Their maximum assimilation efficiency was 32%. At the measured grazing rates, these populations could clear the water in less than two days during July. In Lake Aydat, the rotifers community could play an important role in the regulation of seasonal succession of phytoplankton and bacteria.
