Notes
Grazing rate measurements were performed in the laboratory on Brachionus calyciflorus by using two different techniques: cell counts on a hematimeter (Thoma cell) and the radiotracer method (14C-labelled Chlorella). Results obtained by means of these two methods had no significant differences. After freezing the labelled animals, we found that the clearance rate of the young Brachionus was three times less than that of adult females; yet younger animals filtered more actively than the adults in terms of dry weight.
