How much does it cost to raise ducks in fish ponds?
It costs about 30 thousand yuan to raise ducks in fish ponds. \x0d\ Duck culture technology in fish ponds: \x0d\ 1. Choose suitable water surface \x0d\ Generally, adult fish ponds and second-year-old fish ponds with an area of more than 667 square meters and a water depth of more than 1.5-2 meters are selected as water surfaces, and suitable rivers, lakes and reservoirs can also be selected. Slope protection should be built for sand ridges on newly dug fish ponds, pond ridges with loose soil and duck pens. In addition, ducks are generally not suitable for one-year-old fish ponds, and rice fields are not suitable for mixed culture of fish and ducks. \x0d\ 2。 Choose the right way \x0d\ At present, there are three main ways to implement integrated management of fish and ducks: one is grazing. Is to scatter the ducks on the surface of the pond or lake and rush back to the duck shed at night. This method is beneficial to large-scale fish farming and can save a duck feed, but it has little effect on fish yield. The second is to raise ducks outside the pond. That is to say, build a duck shed near the fish pond, set up a cement activity field and an activity pool, and wash the duck manure and residual materials from the activity field into the fish pond every day. This method is convenient for centralized management of ducks, but it can't give full play to the advantages of symbiosis and mutual benefit between fish and ducks. Third, fish and ducks are mixed. That is, a duck shed is built on the dike of the fish pond, and a part of the dike is enclosed as an activity place for ducks to be directly stocked on the fish pond. This way can give full play to the ecological effect of symbiosis and mutual benefit between fish and ducks. Farmers can choose appropriate management methods according to local conditions to maximize benefits. \x0d\ 3。 Reasonable collocation \x0d\ It is generally appropriate to raise 100- 150 ducks per 667 square meters in fish ponds. If more than 200 fish are released, filter-feeding and omnivorous fish such as silver carp, bighead carp, tilapia or crucian carp are the main ones, and grass, bream or herring are not the main ones. In addition, pay attention to changing water and increasing oxygen. It is not advisable to raise more than 250 ducks per 667 square meters fish pond, otherwise the fish yield will drop significantly. According to the annual output of 40-50 kilograms of manure per duck, the fish pond with ducks increases the fertilizer by 4,800-7,500 kilograms per 667 square meters compared with the fish pond without ducks, which can effectively fertilize the pond water, breed a large number of plankton and provide sufficient feed for the growth of silver carp and bighead carp. Fish ponds for ducks can be mainly silver carp and bighead carp, and 50-75 kilograms of fish can be put in every 667 square meters, 1000- 1500 fish. Grass and herring are the main species, and 75- 1500 kg and 1000- 1500 pieces are released every 6667 square meters. Properly raised, 667 square meters, the net fish production can reach more than 400 kilograms. \x0d\ 4。 Strengthen feeding management \x0d\ In order to facilitate centralized management of ducks, some fish ponds can be enclosed with old nets, screens and other materials as duck activity pools. It is best to raise 2-4 ducks per square meter of water surface, and the height of the net is 40-50 cm above and below the water surface to allow fish to enter and leave freely. Every morning and evening, the ducks are fed in the pond field. At night, after the ducks enter the shed, the duck manure and leftovers in the field are cleaned up in the pond. Drive the ducks out of the shed in the morning, pick them up and clean up the duck manure in the shed into the pool. In summer, ducks discharge a lot of feces, and the water quality is too fat, so it is necessary to replenish fresh water and reduce the amount of fertilization.
