First, the cultivation of a large-scale species of breeding fish breeding pond area of ​​3-5 acres, 1.5 meters depth, silt in the bottom of the pool 20 centimeters. Before stocking, do a 50-60 centimeter of water after clearing up the pool. In the slim bottom pool, it is necessary to add fermented organic fertilizer with 200-300 kg of mu. For fertilizers with a richer bottom, compound fertilizer can be used, with 5-7.5 kg of mu, or 1-2 kg of quick-impact water purifying bacteria, in order to cultivate pupate-like openings. Stocking 3-4 cm of summer flower seedlings, 1,500 mu of stocking, feeding live quail, squid, or fresh fish squid, smashed fish. The survival rate at the end of the year is 90% and the specifications are about 15 centimeters.
Second, the second-in-divided species of fish breeding ponds aquaculture pond area of ​​5 to 10 acres, depth of 1.5 to 1.8 meters, ready to clear the pond before the disinfection preparation. The time is between January and February. Before the seeds are released, they must be sterilized with 3 to 4% salt water for 10 to 15 minutes, with 800 mu of stocked fish and 50 to 60 tails of squid and carp. The feeds were mainly buoyant puffs, supplemented by chilled fish, and were fed once in the afternoon. With the bait to be domesticated after normal feeding, generally feeding to 1 to 1.5 hours after eating as a standard. Support a three-kilowatt aerator to prevent floating heads. Disease prevention is mainly aimed at parasites for medical treatment and breeding. By the end of the year, 50% can meet the requirements for listing 750 grams per tail.
Third, raise the fish species in the winter to raise 500-700 grams of fish in each pond, breed in an area of ​​3-5 acres of ponds. Acre stocking amount of 600-800 after 2-3 months of culture to make each end of specifications to reach 750 to 1000 grams, the price of the listing can be increased by 20 to 30%.
