The invention discloses a fish feed, which consists of 99.98 to 99.995 weight percent of basic high-sugar feed and 0.005 to 0.02 weight percent of betulinic acid, and the basic high-sugar feed contains 30 to 48 weight percent of crude protein, 5 to 12 weight percent of crude fat and 20 to 40 weight percent of starch. The invention also discloses a method for inhibiting the liver injury of the cultured fish induced by the high-sugar feed. According to the method, the high-sugar fish feed containing betulinic acid is fed. The high-sugar fish feed containing betulinic acid is fed to inhibit the generation of excessive fat in the liver tissue of the cultured fish, the fatty liver and inflammation induced by the high-sugar feed are avoided, the normal physiological function of the liver tissue is maintained, and the healthy growth of the fish is promoted. 本发明公开了一种鱼类饲料，由99.98～99.995wt％的基础高糖饲料与0.005～0.02wt％的桦木酸组成，所述基础高糖饲料含有粗蛋白30～48wt％、粗脂肪5～12wt％、淀粉20～40wt％。本发明还公开了一种抑制高糖饲料诱导养殖鱼类肝损伤的方法，该方法为喂养含有桦木酸的高糖鱼类饲料。本发明采用喂养含有桦木酸的
