Channel Catfish Breeding Technology for Adult Fish

Generally, the pond is disinfected with quicklime, bleaching powder, etc. 15~20 days before releasing fish fingerlings, and fish fingerlings are released after a large number of zooplankton appear in the pond water. When raised until the end of the year or 5 months of the following year, the individual weight can reach about 1 kilogram, and the yield per mu can reach 1000～1200 kilogram. Bait feeding and fertilization During production, compound bait should be used as much as possible to improve the quality of feed, and suitable feeding technology should be adopted to ensure stable and high yields. The main raw materials of artificial compound feed for adult fish are: fish meal 13%, soybean cake meal 48.5%, corn meal 13.5%, wheat bran 12%, rice bran Feeding amount and feeding method When the water temperature is 13～20℃, the feeding amount accounts for 2% of the fish body weight. When the water temperature is 20～
