The method comprises the steps of 1 pond culture pre-treatment, 2 fish fry management, 3 fish fry stocking and feeding, 4 screening of fish fries at different stages and 5 daily management. The intestinal tract digestion flora of carassius aurutus is improved by adopting lactic acid bacteria, the feed digestion rate is increased, carassius aurutus can grow rapidly, meanwhile, the lactic acid bacteria have the effect of purifying water, harmful pathogens are restrained, health of the carassius aurutus is ensured, and the culture density is improved to a larger extent; meanwhile, disqualified bodies are removed through screening, the culture and management cost is lowered, and benefits are remarkably improved.

The present invention provides a fish feed for promoting carassius auratus fry growth, wherein the fish feed comprises 5-10 parts of yeast, 20-30 parts of cottonseed cake, 20-30 parts of bean cake, 10-15 parts of corn protein powder, 10-15 parts of bran, 0.1-1.0 part of compound vitamin, and 1-5 parts of a traditional Chinese medicine additive, and the traditional Chinese medicine additive comprises 1-5 parts of codonopsis pilosula, 3-8 parts of acanthopanax senticosus, 5-10 parts of silktree albizia bark, 8-15 parts of milkvetch root, 2-8 parts of aristolochia debilis sieb. et zucc, 2-8 parts of belamcanda chinensis, 2-8 parts of cortex dictamni, 6-15 parts of rhus chinensis mill, 1-5 parts of melia azedarach, 5-10 parts of cortex phellodendri, 3-6 parts of medicated leaven, 3-6 parts of tuckahoe, 2-5 parts of bentonite, 6-15 parts of malt, and 10-15 parts of eucommia ulmoides. According to the present invention, through the reasonable blending, the survival rate of the carassius auratus fry is increased, the resistance of the adult carassius auratus is strong, and the meat of the adult carassius auratus is delicious.
