Qingbeiyan is a new generation of carp species cultivated by Peng Zeyu as a female parent and Jianjian as a male parent under the joint efforts of several researchers from the Fisheries Research Department of Hubei Province and the Science Department of Xiantao City. The greenback has the advantages of fast growth, dark blue scale, resistance to operation, resistance to transportation, low oxygen resistance, and high selling price. For more than a decade, specialized aquaculture farmers in Wuhan, Jingmen, Zaoyang, Ezhou, Harbin, and Zhengzhou have achieved remarkable economic benefits by promoting and breeding this species.
Adult fish raising: an area of ​​5-10 acres, depth of 1.5-2 meters, adequate water, irrigation and drainage facilities. 7-10 acres must be equipped with a 3-kilowatt aerator and a bait feeder.
1, fish stocking. In the "Summer Blossom" of the year, 25 species of fish of about 500 g in size will be cultivated. From December of the year to the month of January to the second year of the year, 2000 backyards will be reared, 300 white lotuses, 100 sea bass, and herring. 10 tails.
2, tame food. Do not feed any feed three days before the taming. Select the center of the pond and fix one point. Feed it artificially every morning at 9:00 in the morning and at 3:30 in the afternoon. Slowly first, make sounds while feeding to form conditional reflections, and the speed of feeding is increased a little when most fish swim. After 5 days, the fish will form a habit of rising and catching food. This will allow the fish to eat full and grow quickly without wasting feed, thus reducing feed costs.
3, daily management. To ensure that the water quality is fat, live, tender and cool, the transparency of fish ponds should be kept at 35cm, and the water depth of the ponds from May to June is kept at 1.3m. During the high-temperature growth season of July, August and September, the pond water depth should be maintained at about 2.5m, and water should be added once a week for 15-20cm each time. The water should be changed every two weeks to maintain the transparency at about 30cm. And to do three times a day tour ponds, timely observation of fish eating and activities, so that training at any time.
4, fish disease prevention. Qingbei grasshoppers are more resistant to disease and less susceptible to disease. However, it is still necessary to sterilize food and water in order to enhance prevention. When the water temperature rose to 20 degrees in May, insecticides were used to kill insects and the water was disinfected and sterilized once every 20 days. In case of illness, oral administration and sterilization of the pool water should be used to prevent aggravation of the disease. Oral administration refers to the addition of 500g/500kg fish in the feed to allow the fish to smoke. The disinfection of the pool water is the use of strong chlorine, extermination of the pool of water disinfection, 3 days for a course of treatment.
