The studies were conducted to find out the optimum densities of Sccharomyces cerevisraeq as the food of three cladocare, Daphnia pulex, Simocephalus vetuloides and Moina rectirostris , at the temperature 28±0 5℃ and natural illumination in the lab. The results showed that the optimum food density was 2.5×10 6 cell·ml 1 for population growth of Moina rectirostris and Simocephalus vetuloide and 0.1×10 6 cell·ml 1 for population growth of Daphnia pulex respectively under five designing gradients.
