The different groups of Artemia sp. were cultured using three diets of Dunaliella salina, Saccharomyces cerevisiae and wheatbran. The results showed a significant difference of growth rate among the groups of Artemia sp. (p<0.05). The group of Artemia sp. fed on wheat bran (group W) was the fastest in growth, While the group fed on Saccharomyces cerevisiae (group S) was the poorest. It was 8 days shorter to reach sexual maturity for the group W than for the others. Besides, The effects of diets on the survival rate was also significantly different (p<0.01). Upon to sexual maturity, the group fed on D. salina (group D) attained the highest survival rate, Group S was the lowest. Further more, The differences of the reproductivity among the groups were great significant (p<0.01). The reproduction frenquency, total numbers of offspring and the average numbers of offspring at each batch of reproduction of group W (5, 320 and 64 respectively) were all higher than those of group S (1.5, 63 and 42). The Artemia sp. of group D didn't reproduce in this experiment. It could be therefore concluded that wheat bran was the best food to culture Artemia sp. and most beneficial to both the growth of the individual Artemia sp. and the population propagation.
