1, water selection. The cages are required to set sheltered waters to sunny areas with wide water surface and sunshine conditions. The perennial water depth is not less than 2 meters. The water quality is non-pollution, the environment is quiet, and the dissolved oxygen is more than 4 milligrams. 2, cage specifications. The use of 0.6-1 cm net clothing, cage area of ​​10-16 square meters, 3.2-3.5 meters high. The frame structure of the cage floats, and the frame is made of bamboo. The heavy metal such as round steel and masonry is used as the sinker to shape the net clothes. The cage setup can be in the form of "product" or "two", with a row distance of 1-2 meters and a box distance of 0.6-1 meters. 3, fish stocking. Ten to 15 days before stocking, cages should be tested for water. Fish species should be disease-free, non-injury, robust and well-defined, with a general stocking density of about 60 per square meter. For the natural wild pupae collected in nature, the specifications are about 2 cm, and they should be raised in a transitional cage for 7-10 days, and fishponds should be used for adaptive breeding. 4, raising grass and summer heat. The amount of water peanuts and other aquatic plants to be stocked in cages is controlled at about 20%. Practice has shown that raising grass can not only be used as a hiding place for fish, but also can prevent water temperature from being too high, regulate water quality, avoid direct sunlight, and facilitate the growth of mullet feeding in summer. 5, scientific feeding. For different growth stages, feed fish should be treated accordingly. In the early stages, the animals should be chopped and fed. Afterwards, according to the individual growth of the mullet, they should be adjusted gradually. The principle of improving palatability and facilitating food intake should be adopted. The daily feed amount is generally 5-6% of the fish's body weight. The number of feedings per day is 2-3 times a day, that is, about 9:00 a.m. and once a time at 4-5 p.m., feeding once a night in the peak season. When feeding, the small smelts are placed on the food table suspended in the cage to reduce feed wastage. The food table can be made by meshing the sides of the small mesh mesh with smooth bamboo clips, and adopting the method of eating while eating, until the fish stop feeding. 6, timely education. During the first 1-2 months of feeding, the squid should be picked up promptly in order to grow quickly, and the individual should be raised. The specifications should be adjusted to avoid competition for food and mutual food. May be consistent. Usually divide 1-2 times before the species reaches 20 cm. 7, prevent disease and escape. Fish species must be strictly sterilized and disease-prevented before they are stocked, and soaked in 3-5% of saline for 10-15 minutes; use disease-free bait fish to feed, use as much as 3-5% of the time before feeding or before storage (refrigerator) Soak in salt water for about 20 minutes; regularly splash lime, once a month; July-September octopuses Wang Shilong season, use wormling powder mixed feed to prevent squid enteritis and other diseases; timely clean up the cage in the dead Fish and feed residue and other rot, to prevent contamination of water quality and water rat bite the net. 8, daily management. Do check 3 times a day, 1 time in the morning, evening and evening. Mainly check whether the feed fish in the cage is completely taken out; check whether the cage is damaged, and timely repair; check the fluctuation of the river, adjust the depth of the cage in time to ensure safe production.
