1. Pond condition The seedling pool is required to be close to the water source, the water quality is good, the water inlet and the water drainage are convenient, the bottom of the pool is flat, there is less silt, and the pool is firm and does not leak. The area of ​​the summer flower cultivation pond is about 667m2. The area of ​​the fish breeding pond is generally 2001m2 to 3335m2, and the water depth is 1.3m to 1.6m. Each fishing pond needs to prepare 1.5kw or 2.5kw aerators, and it is equipped with a pump pump.
2. Clear ponds disinfect fish seedlings before draining the pool water, digging too much silt, so that the sun at the bottom of the pool for 20 days, then the influent water 10cm, with quicklime 75kg ~ 100kg/667m2 watered pulp after Quanchiposa disinfection .
3. Ten days before stocking of fry and fry, the water is filtered to a depth of 0.6m to 1m. Fermented organic fertilizer (manure, cake fat, and the amount depending on the sediment quality of the pond, generally 100kg to 500kg/667m2) To raise the natural planktonic bait in the pool.
4. After fry release fry 3 days to 4 days after hatching, the fry grows to 4cm to 5cm in summer, and similar methods can be used to cultivate the “Four Homes†fry, 30,000 to 50,000 fry per 667m2. It takes about 20 days to 30 days, and then it is sparsely divided into ponds and transferred to the breeding stage. From the summer flowers, about 50g of large-sized fish species are cultivated, 8,000 to 9,000 summer flowers are placed per 667m2, and 600 to 700 fishes of squid and squid are stocked with 6cm to 10cm at the same time.
5. Feed the fish that had just been fished in the pond. Feed the feeds in the pond for 4 days to 5 days, and feed the zooplankton in the pond. When the fry reaches 4.5 cm or more, start feeding the formulated feed. When feeding, tame the food by feeding the fish to the water at the feeding site to send a sound to stimulating the fish before feeding. Then sprinkle a small amount of bait and repeat it repeatedly every 10 seconds. Taming for 10 minutes to 20 minutes, such a cycle of 4 days to 7 days, you can make the fish form the habit of eating groups. With the protein content of the feed is about 40%, fed twice a day, the bait rate of 3% to 5%.
6. Daily management requires dissolved oxygen greater than 3mg/L, pH 6.5-8.3. Every 7 days to 10 days during feeding, new water is exchanged for one time. The depth of water increases with the increase of fish and gradually increases to about 1.5m. Chlorine dioxide is sprayed at a concentration of 0.5mg/L to prevent fish disease. And regulate water quality.
