In order to increase the yield, the tadpoles were safely evacuated to the metamorphosis pool and then the survival rate of the metamorphosis young Rana chensinensis were improved through the complementary feeding. The survival condition of the tadpoles in the different metamorphosis stages was studied using the oxygen aeration experiment. The starvation tolerance of the young Rana chensinensis was studied. The young Rana chensinensis was fed with two-day-old housefly larvae to observe the effect of complementary feeding. The results showed that the concentration of dissolved oxygen in the water increased with the liquid prepared with hydrogen peroxide, which was favorable for the evacuation of the tadpoles. It was optimal that the metamorphosis tadpoles were evacuated before they grew forelimbs. The starvation tolerance of the metamorphosis young Rana chensinensis was 6-8 d. The survival rate of the young Rana chensinensis was improved through the complementary feeding with two-day-old housefly larvae to increase the yield.
