The mutual enrichment between fish and duck is a new way to increase farmers' income. Ducks can eat water in the water to eat frogs, clams, aquatic insects and other harmful organisms on fish; fish can use duck dung, residual baits and other ducks produce waste, so that the water is fresh and the environment is good. Polyculture can eliminate the disadvantages of fish and duck breeding. Mixed fish and duck should master the following main technologies.
First, the construction of fish ponds and duck houses. The fish ponds are required to choose near-water sources, where the water quality is good and where there is no pollution. The pool-shaped east-west direction is required, the depth of water storage is 1.5 meters or more, and the pond is wide and sloped, covering an area of ​​5 acres. The duck house should be built on the northern slope of the fish pond to keep the light. Before the house is used, the sheds with a height of about 0.7 meters are surrounded by mesh or bamboo pieces. The underwater part is about 0.5 meters away from the surface of the fish pond. Activity venues.
Second, fish, ducks stocking with. Fish species are dominated by large-scale fertilized waters and omnivorous fish, with no or less herbivorous fish. Under normal circumstances, cod, eel accounted for 45%, cod, eel accounted for 50%, grass, cockroaches can account for 5%, acre stocking in the 1500-2000 tail, according to Tangkou conditions, management conditions flexible learning system. Each acre pond can raise about 120 ducks, with a duck house of 25 square meters.
Third, daily management. Observe the ponds on a daily basis and observe the feeding and activities of fish and ducks. Usually, it is necessary to add water and change water to keep the water quality fertile, live, tender, and cool. In summer and autumn, it is necessary to prevent the floating of fish heads and flooding phenomenon. The duck feed should be kept fresh and not mildewed and fed 3 to 4 times a day. According to the amount of fish stocks, fish feed should be fed as appropriate. The duck house must be cleaned and kept clean. Excess duck manure can be accumulated and fermented. The water is fat and thin, and it is thrown into the pool in divided times.
Fourth, disease prevention and control. Fish and duck diseases adhere to the principle of prevention. Before the fish species are stocked, the fish ponds shall be cleared of excessive silt, and the whole pool shall be disinfected and disinfected with quicklime. The fish species shall be soaked in 2.5%-4% saline solution and then entered into the pool. In May-September, every 15 to 20 days, lime slurry is splashed once every 1 to 5 times. Before the onset of fish season, it is fed with baits such as oxytetracycline and furazolid for 5-7 days. The duck playground is well padded with straw and is frequently disinfected with bleaching liquid. Young ducks are injected with immunization vaccines to enhance their resistance to diseases. Regularly add norfloxacin, erythromycin, furazolidone and other drugs to the duck feed to prevent intestinal diseases in ducks.
