The invention discloses a puffing carp feed. The puffing carp feed is prepared from the following components in parts by weight: 5-10 parts of fish meal, 20-40 parts of dehulled soybean meal, 10-30 parts of rapeseed meal, 15-20 parts of flour, 10-15 parts of rice bran, 1-4 parts of soybean oil, 1-3 parts of bentonite, 1-3 parts of calcium dihydrogen phosphate, 0.1-0.5 part of choline chloride, 0.1-0.5 part of composite vitamins, 0.1-0.5 part of composite trace elements, 0.1-0.5 part of a powdery microecological preparation and 0.5-2 parts of a liquid microecological preparation. The microecological preparations contained in the puffing carp feed disclosed by the invention can purify water bodies, can reduce the content of ammonia, nitrogen and nitrite in water bodies, can complement the defects of endogenous digestive enzymes of carps, can improve the feed transformation efficiency, can strengthen the disease resistance of the carps and can increase the survival rate. Compared with a feed in a control group, the puffing carp feed added with the powdery microecological preparation and the liquid microecological preparation disclosed by the invention has the advantages that the growth rate is increased by 8% or above, bait coefficients are obviously reduced, and growth promotion effects are obvious.
