The feed used for pond intensive culture of grass carp is based on fish feed and supplemented by green feed. The compound feed consists mainly of fishmeal, soybean meal, wheat bran, sub-powder, corn, and refined grass, and is compounded with mineral salt, multi-dimensional and amino acid compound additives, requiring comprehensive feed nutrition, including crude protein 20%, crude fat 4%, 40% of carbohydrates, 8% to 10% of cellulose, green feed fed alfalfa, ryegrass, Sudan grass, dry grass, aquatic grass, etc., require fresh grass for the grass carp to digest.
Feeding high-quality feed can cause grass carp to have less disease and rapid growth. Intensive culture ponds should strictly adhere to the "quality, quantity, timing, and fixed-point" feeding. Routine feeding is from 2 to 4 times daily from mid-March to May, 3 times daily from mid-June to August, and 4 times from mid-August to October. From June onwards, feed green feed once a day. The amount of feed should not be too large. It is advisable to use 7-8 to prevent overgrowth or hunger.
Grass carp eat fierce and bulimia, one-time feeding too much prone to feed in the intestines to expand the fish to death. The daily feeding amount is 1.5%~1.8% of the weight of grass carp, which is fed in three times.
