The invention discloses quasipaa spinosa tadpole feed and a preparation method thereof. The quasipaa spinosa tadpole feed is prepared from fish meal, earthworm powder, insect protein mixed powder, corn flour, wheat bran powder, bean pulp, rapeseed dregs, strong flour, alpha-starch, wheat flour, enteromorpha seaweed meal, mulberry leaf powder, yeast powder, fish oil, soybean oil, phosphatide oil, 50-percent choline chloride, beta-1,3 glucan, mineral substance premixes, vitamin premixes, lactic acid bacteria and bacillus subtilis through multiple times of mixing and smashing. The feed has the advantages that used raw material sources are stable; a formula is reasonable; a production process is simple and feasible; the whole nutritional requirements of the high-density cultivation of quasipaa spinosa tadpoles can be met; the cost is relatively low; the problems of bait storage difficulty, germ breeding and the like in the cultivation process can be effectively solved; the quality is safe and reliable; the tadpoles can fast grow; the death rate is low; the metamorphosis time is early; the feed conversion rate is high; the cultivation benefits are better.
