Ooni fish breeding and breeding technology

When the water temperature rises above 25℃, it is put into an earthen pond and raised, with 300-500 male and female fish per acre; when the water temperature rises to 28℃, the male and female fish are fertilized in the mouth of the female fish. Under the regular stocking of bighead carp, silver carp, catfish, dace, carp, and crucian carp, 700-1,000 onii fish per acre should be raised in fertilizer ponds, and 300-500 fish should be raised in wastewater ponds. The number can be increased to 2,000 in fish ponds that combine fish and pig fertilizer with rich feed. The feed is mainly pellet feed containing more than 28% protein. It is fed twice a day at 9 am and 5 pm. Each kilogram of fish requires about 1?７-2 kilograms of feed.
