Pond fish and duck polyculture is one of the integrated farming and animal husbandry modes. Through the formation of an artificial composite ecosystem, the water surface is fully utilized, and production and consumption are increased. The aquaculture efficiency is very obvious. Here, we mainly introduce the technical specifications of fish and duck mixed with more than 350kg per mu.
I. Breeding facilities
1. The pond area is 3000-4500m2 (about 5-7 mu), the water depth is more than 1.5m, the water source is sufficient, drainage and irrigation are convenient, and the facilities are perfect.
2. Ponds on the north side of the pond are built with duck sheds and pond slopes are used as playgrounds, and Tong Kok Wai Swimming Pool. The area of ​​sheds, poplars and ponds was set at 6 feathers/m2, 3-4 feathers/m2, and 2-3 feathers per m2.
Second, fingerling duck breeding
1. Fish species stocking
In order to use oysters, non-cockroaches, cockroaches, white pebbles, and other filter-feeding fish, take care of grass, green, squid and so on. The main fish stocking specifications 50-70 grams / tail, the total amount of 50-75kg for each 667m2, stocking more than seven species, require winter, medium-term appropriate sets of summer flowers.
2. Each 667m2 of water is bred with 100-120 ducks. The selection of improved varieties or combinations of hybrids is preferred. In spring and summer, ducks are mainly raised in meat and autumn.
Third, feeding and management
1. Fish culture management
(1) Fertilizing and feeding fish species 5 to 7 days before stocking Mushi quail cooked duck manure 100kg as base fertilizer. After stocking, the average daily fish and duck manure is about 8% of the fish's body weight. Pay attention to a small amount of ground facilities, 25 °C below the next day. Application, fertilize every day above 25°C, spread evenly throughout the pool; 0.15 mu of green fodder is allocated per acre of water surface, winter species of black eucalyptus, summer species of Sudan grass, and green fish are cut; in addition, depending on the growth of fish, 3 to 5 % feeding rate supplement feed or batch material.
(2) Water quality management Duck manure water has high oxygen consumption. Observe the water color normally, adjust the water quality, clean up the water and remnants in time, make the water and fertilizer thin and moderate, and the dissolved oxygen is sufficient. The transparency is about 25-30cm; Once every 5-7 days, change the amount of water is about 15% of the pond water.
(3) Disease prevention measures Before the pond is used, use 75kg/mu quicklime to clear the pond before the suntan pond is used. The fish species should be immersed in the pool and sanitized with 3% salt water. A grass rack and food table should be set up in the pond. From April to November, every half month Once the medicine has been hung on the bag (bag), 30ppm quicklime will be splashed once, and the fish and medicine ingredients will be taken internally to prevent diseases. In the high temperature season, less manure will be applied, and new water or mechanical oxygenation measures shall be taken to prevent flooding.
2. Shed Duck Management
According to the different living habits and growth patterns of ducks, ducks and ducks, scientific feeding and management. The first is to keep the duck houses well ventilated, clean and dry, place mat grass in due course, timely grazing ducks group activities, swimming; the second is a reasonable mix of duck feed (to use the full price material is better), keep the feed diet relatively stable, do not Replacement affects the digestion, absorption and growth of ducks. Daily feeding should be performed regularly, quantitatively and qualitatively to maintain constant drinking water. Third, strict anti-epidemic measures should be implemented. All kinds of vaccines should be injected on time, and diseased ducks should be isolated and removed in a timely manner. Drugs; four is to pay attention to weather, animal pests and pesticides and chemical poisoning.
