1 pond conditions Qihe River pond culture area, generally 2000-3300 square meters, the depth required 1.5-2.5 meters, the bottom of the pool is flat, retain about 10 cm of mud. Adequate water supply, convenient drainage and irrigation, and good water quality.
2 Before clearing the fish ponds for fertilization, drain the pool water, thoroughly clear the pond, and remove the debris. In the 7-10 days before the fish seedlings in the pond, 150kg/667m2 of quicklime was used to dilute and disinfect the whole pool. Then apply enough basal fertilizer to compost 500-800 kg/667 square meters of human and animal manure, and then inject fresh water.
3 The stocking time of the fish breeding Qihe oysters is best in the late autumn or early winter, when the stocking is conducive to early fry and early growth. Stocking density: 2,000 to 3,000 tail fish stocks of about 50 grams per 667 square meters, about 100 grams of Qihe carp fingerlings of about 1500 to 2000 tails, about 1,000 fish seeds of about 100 grams, and about 150 grams of carp seeds. Squid 250-300 tail. Fish species require a healthy body. No disease or injury. When the fingerlings are in the pool, soak with 10-30 g/L salt water for 4-5 minutes to prevent the bacteria from entering the pond.
4 daily management
4.1 Feeding In the winter and spring weather, it is necessary to feed some concentrate feeds, and the amount of each feed will account for 1% to 2% of the weight of the whole carp. At the end of autumn and early winter, due to the drop of water temperature, feeding two times a day, each feeding amount accounts for 3%-5% of the carp's weight; from May to September, the water temperature is high, the fish eats strongly, 3-4 times a day feeding, casting The bait accounts for 5%-7% of the fish's body weight. How much to feed, but also depending on the season, the weather and the fish's food intake flexibility. The feeds are mainly rice bran, bran, cakes, corn flour and pellet feed.

Normally every 10 to 15 days. Once every 7 to 5 months, fill every 5 to 7 days. If water is found Thick, timely change old water 1/4. At the same time, after every 10 days, 40kg/667 square meters of lime are used to churn out the whole pool to regulate water quality and prevent fish diseases.
5 Fish disease prevention and prevention takes a precautionary approach. During feed management, it is necessary to regularly spill drugs to prevent fish disease. Use 90% crystal trichlorfon 0.5 g/m3 per month and effectively disinfect 0.6 g/month. Cubic or fish and shrimp 0.5 g/m3 aqueous solution shall be splashed alternately in order to prevent the occurrence of parasitic diseases and bacterial fish diseases. In the season of fish disease, bacon is prepared by feeding 40 kg of sulfa drugs to 100 kg of fish, and the course of treatment is 6 days.
