Fish and ducks are good for neighbor breeding
Fish and duck polyculture can make full use of the water surface, achieve resource sharing, benign circulation, and superb economic benefits.
Pond selection
The ponds that are supported by fish and ducks should be selected where there is no pollution, good water quality, adequate water supply, and convenient transportation. The ratio of length to width of the east-west direction of the pond is 2-3:1, and the inner slope of the pool base is 1:2-2.5. The bottom of the pond is required to be flat. The slope of the pond can be gently slanted toward the direction of the outlet to facilitate dry ponds. The pond area of ​​3-7 acres is good, the water depth is 2-3 meters, and the pond is equipped with separate facilities for entering, draining, and stopping fish.
Duck Shed Construction
The duck canopy should be chosen to face south to the south, where the terrain is high, the sun is abundant, and it is relatively dry. The slope of the pond is gentle, which is conducive to the places where the ducklings come out of the pond and walk and feed. In winter, it can seal and insulate, in the summer, it can be ventilated and cooled, and in the rainy season, it can discharge water and drain well Each duck shed has an area of ​​120-150 square meters. There are two other duck group activities. One is a corner of a net pond, which is used as a foraging site for growing ducks, and the other is a pool base or pool slope near the duck shed. Activity field.
Fish and duck polyculture ratio
50-60 kg of fish per acre, 70%-80% of quail, other omnivorous fish, supporting 80-100 ducks per acre of water, fish species increased 7-8 times, breeding yield per mu Up to 400-500 kg. Or put 75-85 kilograms per mu, 70%-80% eel, 150-200 ducks per acre, fish species gain 6-7 times, mu yield up to 550-650 kilograms. There are also culturable omnivorous fishes, including Rophia, Aza, and Earthworms, which account for 60%-70% of the population. Others are filter-feeding fish. According to the long-term experience in aquaculture production, generally, each year of raising a duck can produce more than 3 kilograms of fish, and farmers can flexibly apply it according to specific conditions.
Fish Management
The first is clear pond disinfection. In front of the fish pond, 1 meter deep water per mu, tea bran 50 kilograms of water is used to break the water, and then the whole pond is splashed on one day and then limed 100 kilograms of water is used to dissolve the whole pond. After 7-10 days of toxicity, the fish can be released. Breeding. The second is the disinfection of fingerlings. Before the fish species falls, the fish body is bathed with 3% saline for 5 minutes to kill bacteria and parasites; grass fingerlings are injected with vaccines for immune prevention and falling pond culture. The third is scientific feeding. Feeding and feeding shall be done in “four setsâ€, that is, timing, qualitative, quantitative, and fixed points, and feeds should be fed in sufficient quantity, quality, and palatable feed. In summer and autumn, the total body weight of fish can be fed 3%-5%. Spring can be cast 1%-3%. The fourth is water quality management. Pool water should be kept fat, live, tender, and cool. The transparency should be controlled at about 30 centimeters, and the pool water pH should be maintained at 7-8. The fifth is prevention and treatment of fish diseases. Change the water every 7-10 days in summer and autumn, discharge 30 centimeters of old water and pour in 30-40 centimeters of new water to keep the water quality relatively stable. Every 710 days, use 10,000 units of bleached and pulverized water. 1 meter deep water per acre is treated with 20 kg of quicklime to dissolve the entire pond. Aerators should be activated at the right time to prevent fish floating. Feed the baits at the right time to enhance the fish's disease resistance and promote growth.
Duck management
Scientific breeding, do a reasonable mix of feed, regular quantitative feeding, do not feed rotten degenerate feed, drinking water clean enough, temperature, humidity, density appropriate, fresh air. Do a good job in cleaning the duck shed, adhere to disinfection, cleaning duck shed, people can not easily enter the duck shed to eliminate the source of infectious diseases. Ducks were injected with a vaccine at 30 days of age to prevent duck plague, and were vaccinated against bird flu at 70-80 days of age.
