The practice of Mao Shuliang, a fish farm in the Institute of Agricultural Sciences in Jiangkou County, Guizhou Province, proved that adopting a wheeled catcher, that is, a “stocking at one time, fishing in batches, and a small cup at Pudongâ€, is one of the important measures for raising fish to obtain high yields. Why can steal stealing technology produce roads?
(l) Mitigating the contradiction between polyculture density, feeding and fertilization, and the incompatibility of oxygen in ponds and harbors.
(2) The lack of stocking of the fish in the early feeding period was avoided and the disadvantages of the water body could not be fully utilized.
(3) Achieved a proper year-round cultivation, rational use of feed, and give full play to the annual production potential of the pond. Round-robin rotation generally starts from June each year and ends at the end of the year. For the first time in early June, more than 0.5 kg of squid and squid were caught and listed, and in the later days, squid summer flowers were added at the end of each year, with 100 tails per mu, as the second-year cultivated large fingerlings; the second time in 7 From the beginning of the month to the beginning of August, 0.5 kg of grass carp, 1.5 kg of grass carp, and 0. L kg of tilapia was arrested and put on the market. L-0.2 kilograms of squid, 100-200 per acre, and add 13 cm long carp, 200 per mu, the third time around the Mid-Autumn Festival; the fourth time in mid-late and late October Fish caught in the above specifications will still be caught, but tilapia should be caught in mid-to-late October. Otherwise, it will freeze and die when the water temperature drops.
