| Abstract: | The grazing characteristics and biomass of a marine ciliate, Euplotes vannus fed by bacteria and microalgae were observed and discussed. The results exhibit that the natural rate of increase (r) of E. vannus feeding on bacteria is 0.64/d, and the energy transformation rate is around 44.2%, while in another experimental population fed with algae they are 0.37/d and 21.6% respectively. The population growth began almost immediately after the ciliate was inoculated and no lag phase was recognized in the culture of populations provided with sufficient food. |
