Feeding crabs in the spring, summer and autumn, the amount of pig blood in the crab feed amount of 10% to 20%. During the wintering period of the crabs, in order not to reduce the body weight of the crabs, appropriate palatability feeds should be properly fed during the holding period. The feeds can be made of cooked pig blood, wheat, corn, and sorghum. The amount of feed decreased with the decrease of temperature, which accounted for 4% of the total weight of the crab in the initial period, and decreased to 2% after the frost fell. The water temperature below 8°C can be fed less or no more every other day.

Feed adult fish into ponds with a large proportion of lean water or large proportions of fertilizers. Sprinkle the pig's blood with stubble quails that are removed from the pig's stomach when the pigs are slaughtered, both as feed and as fertilizer. Practice has shown that, in the adult fish ponds fed with pig blood, the weight gain of the fish is better than that of ponds fed with rapeseed cake.

It is worth noting that the pig blood used must be fresh blood that has just been slaughtered to prevent pig blood from spoiling and causing fish and shrimp poisoning, and to use blood from healthy pigs to prevent the spread of certain diseases; in addition, pig blood The low content of calcium and phosphorus in the fish can not meet the growth needs of fish and shrimp. It is best to add 2% to 3% of minerals in the feed at the same time. The soluble calcium and phosphorus should be periodically poured into the pool.
