The invention relates to a mixed feed for mixed aquaculture of freshwater fishes. The mixed feed includes a basic material. The basic material includes fish meal, soybean meal, wheat, cottonseed meal, rapeseed meal and soybean oil, and also includes by weight: 1.5-2.2% of calcium phosphate, 1.5-2.2% of bentonite, 1.5-2.2% of zeolite powder, 0.1-0.25% of choline chloride, 0.1-0.25% of salt, 0.02-0.05% of compound probiotics, 0.04-0.08% of vitamin C, 0.005-0.02% of allicin, 1.0-2.0% of compound vitamins and 1.0-2.5% of compound mineral salts. The feed is suitable for intensive culture or polyculture of megalobrama amblycephala, black carp, grass carp, common carp and the like, so that the freshwater fish feed is generalized, the return rate of the feed is improved, the aquaculture water eutrophication and fish liver and gallbladder diseases are reduced, the output of unit aquatic products is raised, and the economic benefits of farmers are significantly improved.
