1. The selection area of ​​the pond is appropriate from 2 to 10 mu, the water depth is from 1.2 to 2 meters, the bottom of the pool is flat, the sediment thickness is 10 to 25 centimeters, the water source is sufficient, the water injection and drainage are convenient, and the water intake and drainage are separated.
2. Preparations before stocking (1) 15 days before stocking in clear ponds, fish should be disinfected with quicklime (75kg/mu to 100kg/mu dry pond) to completely kill potential pathogens and predators. (2) Fertilizer fish species should be fed with fermented organic fertilizer 100 kilograms per mu for 7 days before stocking to cultivate bait organisms in the water body. (3) The feedstuff stand is constructed around the pond with reeds or bamboo mats and other materials to construct 1 to 2 feed stands, and a small amount of water grass can be planted.
3. Fish species are stocked with 500 to 1000 tails of 10 cm or more in standard species in winter and spring, and they can also be stocked with 20% of fish and other filter-feeding fish.
4. Daily management (1) There are three types of feeds that can be fed. One is a live bait fish, the size is from 1/5 to 1/2 the length of the white fish of the redmouth fish; the second is the chilled or fresh Fish; The third is artificial feed, requiring feed protein content of 35% to 40%, particle size of 2 mm to 3 mm. (2) Water quality management Within one month after stocking, pool water is added to normal water level. Breeding pond mouth should be equipped with aeration equipment, preferably a water pump. When water is added, it is not directly injected into the pond. After buffering, it slowly flows into the pond to prevent the white fish from jumping and suffers losses. The water injection should be repeated several times to keep the pool water fresh and the oxygen is sufficient. . (3) Disease prevention and treatment shall be mainly prevention. In addition to the disinfection of clear ponds before stocking, the whole pool shall be periodically disinfected with quicklime of 5 kg/mu to 10 kg/mu.
5. After one year of harvesting, the fish can be caught and listed for harvesting. Usually, the catch is used first, and the rest is collected again from dry ponds. Listed specifications for the 0.4 kg / tail or more, the fish did not meet the market specifications should be placed in other ponds fed.
