Abstract: | Feeding experiments were carried out on the harpacticoid copepods Tisbe 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-1, indicating a carbon requirement of 1 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. |
