Abstract: The feeding experimemt of larva Pomoxis nigromaculatus with microzooplankton, fish paste, egg yolk, eel formula feed. The results showed that after 20 days of cultivating, there were significant differences in first feeding rate, growth rate and survival rate of larva P. nigromaculatus (P＜0.05). The group of microzooplankton had the highest first feeding rate, which was 94.44%, and had the highest growth rate, the average daily length reached 0.43 mm, and the final survival rate was 56.03%. The growth rate and final survival rates of the fish paste, egg yolk and eel feed groups were very low, the average daily length reached 0.22, 0.14 and 0.11 mm, and the final survival rate were 15.24%, 12.80% and 8.05%, respectively. In conclusion, under the conditions of this experiment, the best diet of larva P. nigromaculatus was microzooplankton. The nonlinear growth model of logistic could fit black crappie larva of feeding using different initial feed growth curve well (Ｒ2≥0.96).
