As a kind of aquaculture model adapted to local conditions, fish and duck polyculture has been welcomed by people in some places in our province. This model can make full use of the water behind the house to develop ecological aquaculture, and can achieve considerable economic benefits. It is indeed an effective way to enrich the people and build a strong town. In order to facilitate the promotion, the technical points are introduced as follows.
First, repair pond construction 1. Pond trimming. The east-west direction of the pond is a good rectangle. The ratio of length to width is 2:1 to 3:1, and the slope ratio in the pool is 1:2 to 1:2.5. The bottom of the pond is flat, and the side that is slightly drained can be inclined to facilitate the dry pond. The area of ​​the pond is 2 to 3 mu, and the depth of the pool is 1.5 to 2 meters. The pond is provided with inlets, outlets, and fish-stopping facilities. For the original shallow, small, dry and old ponds, the new ponds can be rebuilt.
2. Duck shed construction. The duck shed should face south to the south and be built in a dry place with high topography and sunshine so that it can be kept warm in the winter, cool down in summer, and drain well in the rainy season. The duck shed covers an area of ​​120-150 square meters and has two activity areas. The first is to use an old mesh to surround the corner of the fish pond (the area does not exceed 1/4 of the total area of ​​the pond) as an active water surface. The second is to use a bamboo fence around the duck shed to surround a piece of pond or pool slope as a dry field activity area, which is twice the area of ​​the duck shed.
Second, the harmonious combination of fish and duck polyculture mode, with the water as the center, mainly fish, fish and duck rational allocation, to duck to promote fish, fish and duck double income purposes. In general, the following two polyculture modes can be adopted. First, 50-60 kg of fingerlings per mu of water surface, 70%-80% of filter-feeding fish, and 60-80 ducks per mu. The second is to put 75-85 kg of fish per acre of water, 70%-80% of filter-feeding fish, and 100-200 ducks per acre of water.
Production experience shows that, in general, every single duck can produce 3 kg of commercial fish.
Third, science polyculture 1. fish culture. (1) Clear pond. In front of the fish ponds, the used ponds should be disinfected, and 70 to 100 kg of lime should be used per acre. The whole pool should be splashed evenly after being used in the slurry. (2) Disinfection of fingerlings. When the fish species is under the pond, the fish is soaked in a 3% saline solution for 5 minutes. The grass carp is immunized with a vaccine. (3) feeding. To Feed palatable full price fish feed, daily feeds can be calculated from 2% to 5% of the fish's total body weight. (4) Water quality. As the saying goes, to raise a pool of fish, we must first manage a pool of water. The water quality should be kept fat, live, tender and cool. (5) Qintangtang. Do a good job of anti-escape, disease prevention, flood prevention, and anti-theft work.
2. Ducks. (1) Adopt scientific breeding to achieve a reasonable mix of feeds, feeding regularly and quantitatively, and not feeding mildew or rotten feed. The temperature, humidity and density are suitable to ensure fresh air in the duck house. (2) Prevention and treatment of diseases is an important part of the development of duck production. Therefore, the first is to do a good job cleaning the duck shed, adhere to disinfection, people do not enter the duck shed, to cut off the source of infection. Second, ducks were injected with a vaccine at 30 days of age and cholera vaccine was given at 70 to 80 days of age to prevent cholera.
