The invention discloses a cherax quadricarinatus compound feed for enhancing immunity. The cherax quadricarinatus compound feed comprises the following components in percentage by mass: 6-9% of fish meal, 22-26% of soybean meal, 5-7% of blood powder, 15-20% of peanut bran, 3-5% of beer yeast, 9-11% of cane sugar, 9-11% of corn starch, 0.5-1.5% of shell powder, 0.1-0.2% of sodium chloride, 1.0-3.0%of composite vitamins, 0.5-1.5% of composite minerals, 0.5-1.5% of choline chloride, 1.0-2.0% of calcium dihydrogen phosphate, 1.0-2.0% of an immunopotentiating agent, 1.0-2.0% of sodium alginate, 2.5-3.2% of soybean oil, 2.5-3.2% of peanut oil and the balance of cellulose. The cherax quadricarinatus compound feed disclosed by the invention is comprehensive and balanced in nutrients, and can meetgrowth and immunity requirements of cherax quadricarinatus for various nutrients, wherein the composite vitamins, the composite mineral substances and the immunopotentiating agent which are added canmeet nutritional requirements of the cherax quadricarinatus, and the immunity and the stress resistant capacity of the cherax quadricarinatus can be notably improved; and in addition, animal proteinsuch as fish meal is replaced with vegetable protein such as the soybean meal, the peanut bran and the like, so that the breeding cost can be reduced.
