Oni fish farming technology

Oni fish has the advantages of good body shape and meat quality, diverse feeding habits, fast growth, high meat production rate, and delicious taste. Fish species of about 5 centimeters can weigh up to about 500 grams after being raised for 5 months. They grow 20%~75kg to 100kg of quicklime per 667 square meters to disinfect. 2.The stocking density of fish species should be determined according to pond conditions, fish species specifications and management level. Raise for a period of time. When the Ooni fish grows to more than 100 grams, put 4cm~6cm California bass or catfish 50 tails~667 square meters. 3.Feeding When the fish species are put into the pond, they feed on plankton in the water and feed a small amount of feed at the same time. Feed normally after 1 week. Generally, before the individual weight 200 grams, the daily feeding amount is 4% to 7% of the fish's body weight. Use pellet feed with a particle size of 3 mm and feed it 3 times a day. The feed is thrown on the food table, which is located 2 meters away from the edge of the pond. There are 3 per 667 square meters. Each time the fish is fed, the fish will be 80% full. 4.Daily management During the breeding period, the pool water should be kept dark green with a transparency of 25cm ~ 30cm. If the water color turns black or smells bad, you should change the water immediately. Drain out 1/3~1/2 of the pool water first, and then inject new water. Sprinkle 1 gram of bleaching powder into the entire pond every month; 1 times every month; use allicin, Yubikang and other drugs mixed with bait every 20 days (operate according to the instructions) and feed 1 treatment courses, each treatment course is
