The invention relates to the field of large yellow croaker culture, and discloses a feed, a preparation method and application thereof, and a large yellow croaker culture method. The feed comprises fish meal, defatted hermetia illucens powder, krill powder, corn protein powder, fermented soybean meal, wheat gluten, fish oil, wheat flour, alpha-starch, soybean lecithin, vitamins, minerals, monocalcium phosphate, choline chloride, taurine, cuttlefish paste and a preservative, wherein the content of the fish meal is 20-40 wt%, the content of the defatted hermetia illucens powder, the fermented soybean meal, the wheat gluten and the wheat flour is 5-15wt%, the content of the krill powder, the corn protein powder, the fish oil and the alpha-starch is 2-10 wt%, the content of the soybean lecithin and the monocalcium phosphate is 0.5-3wt%, the content of the vitamins, the minerals, choline chloride and the taurine is 0.5-2wt%, the content of the cuttlefish paste is 0.1-1wt%, and the content of the preservative is 0.01-0.2 wt%. After the feed is adopted to culture the large yellow croakers, the growth performance, body composition, serum biochemical indexes, antibacterial and antioxidant results of the large yellow croakers are good, and the culture effect of saving the feed cost and ensuring the health of the fish bodies is achieved. |
