✦ Synopsis

Feeding experiments were carried out on the harpacticoid copepods ~s b e holothuriae and Paramphiascella vararensis, using various species of marine and brackish water bacteria as food. Short-term experiments with 3H-labelled bacteria are described, as well as experiments covering longer periods of time using non-labelled, dried bacteria. Results show that for both T. holothuriae and P. vararensis, the amount of dry bacteria consumed ranged from 2.06 to 7.07 #g copepod-1 day -I, indicating a carbon requirement of I to 3.5 ~g copepod-1 day-1. The food value of the bacteria strains tested is given in terms of the generation time of the copepods raised on these bacteria.
