The forktail is native to North America. Large freshwater fish were introduced to China in 1978. Meat is delicious, easy to breed, and is the main target for freshwater aquaculture in the future. According to relevant data, the yield of cage culture can reach 137.6-156.7kg/?, and its cage culture is introduced as follows:
The fry stocking time is usually arranged in mid-April. It can be raised to 50-60g/tail and transferred to the cage for breeding. The fry is put on 150-200 fishes per square meter cage. Disinfect the fish body immediately after entering the box (with 3% salt water Wash the fish body for 3-5 minutes). After 5-7 days of domestication, normal feeding begins. The feed is a pelleted feed made from fishmeal, peanut, bran and buckwheat. Artificial hand throwing feed, feeding twice a day (9:00 am and 5:00 pm), feeding the amount of 2.5% -4% of fish weight, usually pay attention to observe the fish's activity and eating conditions, appropriate increase or decrease vote Feeding amount. In order to prevent the occurrence of fish disease, every 15-20 days, the cages spilled quicklime 1 time, splashed for 3 days, and fed the bait at the same time for 4-5 days. The bait was added 1g norfloxacin per 500kg of pellet feed + 500g. High stability vitamin + 2g Shanghai multi-dimensional factors.
It can be harvested and put on the market for 5 months, and the weight can reach 500-800kg. The wholesale price at the pond edge is 17-19 yuan/kg, which is a kind of profitable and worthy promotion.
