Notes

Changes in dry weight, carbon, nitrogen, hydrogen and ash content of the rotifer Brachionus plicatilis were investigated during population growth in culture. Also caloric equivalent was estimated from carbon content. Body dry weight and weight of C, N, and H increased with increasing the egg/female ratio of the population, while ash content remained constant and ash content decreased. The caloric equivalent ranged from 1278 ucal to 4406 ucal for rotifers from 314 ug to 846 ug of dry weight.
