The invention relates to an environment-friendly organic fish feed made from wheat bran. Wheat a bran additive, a humic additive and a rotten worm additive are taken as main additives, and then a fermentation agent made from bacillus subtilis, lactic acid bacteria, saccharomycetes, photosynthetic bacteria, actinomycetes, phosphate-solubilizing bacteria and potassium-solubilizing bacteria is added for fermentation and a vitamin additive and an amino acid additive are added; the ingredient source is safe, green and environmentally friendly; the environment-friendly organic fish feed is nutritional and efficient, is capable of increasing the survival rate of fish, reducing bacterial virus in fishpond and promoting the disease resistance of fish; and the high-fiber high-starch effect of the environment-friendly organic fish feed can increase the growth rate of the fish and improve the fish taste.
