Therefore, the feeding and management mainly includes fertilization, feeding and daily management. Fertilizers can be various fermented manures and green manures. Apply manure 200300kg/ acres or green manure 300kg/ acres every week. Generally, the food should be eaten within 1~2 hours after feeding. You can feed more appropriately. If you do not finish feeding on time, you should feed less or stop feeding. The cage uses bamboo and wood frames and polyethylene mesh as the cage to make a rectangular cage with a length of 5m, a width of 4m and a height of 2m. The feed is mainly pellet feed containing 28% or more protein. It is fed twice a day in the morning 9 and in the afternoon 17. The feed coefficient is approximately 1.724 times a day. The daily feeding amount is generally changed appropriately within the range of 310% of the fish body weight.
