The invention discloses a feed additive capable of improving the immunity of seawater fishes and a preparation method thereof. The feed additive is prepared from the following components in parts by mass: 4 to 8 parts of methionine, 6 to 8 parts of selenium yeast, 5 to 15 parts of acetic ester, 1 to 5 parts of clostridium butyricum, 5 to 15 parts of carnitine, 5 to 7 parts of calcium hydrophosphate, 0.6 to 1 part of attractant, 10 to 12 parts of mannan oligosaccharide, 3 to 5 parts of inositol, 4 to 6 parts of organic selenium, 2 to 4 parts of crystal taurine, 13 to 15 parts of polyxylose and 3 to 5 parts of photosynthetic bacteria. By adopting the feed additive, the survival rates of certain kinds of seawater fishes can be increased when infected with harveyi bacteria; the cultured seawater fishes have high survival rate, bright body color, high anti-stress capability and low feed coefficient. 本发明公开了种增强海水鱼免疫力的饲料添加剂及其制备方法，由以下质量份数配方成分组成：蛋氨酸4-8份、酵母硒6-8份、醋酸酯5-15份、丁酸梭菌1-5份、肉碱5-15份、磷酸氢钙5-7份、诱食剂0.6-1份、甘露寡糖10-12份、肌醇
