Green and novel mode of mixed culture of fish and duck how to manage the mixed culture pond of fish and duck

Mixed culture of fish and duck, reasonable transformation of substances in water, maintain a virtuous circle. Duck activities in the water, can cool the body, healthy growth, fish can make use of the waste discharged by the duck to keep the water clean. The mixed culture of fish and duck needs to strengthen the culture management, which will bring high benefit.

Fish and duck

1. Adjust the water quality. Due to the activities of ducks, the evaporation of water in fish-duck mixed culture ponds is often larger, coupled with the discharge of duck manure and residual feed, the water quality is very easy to deteriorate, therefore, fish-duck mixed culture ponds should frequently add water to change water, keep the water depth above 1.2 meters, and keep the water level as stable as possible. Don't go up and down. In the high temperature season, the frequency of changing water should be increased, preferably once a day, to prevent fish from anoxia, floating head and pan pond. If the water quality changes, you should immediately add new water, can also be sprinkled with oxygenators, water quality regulators and other drugs, temporary first aid.

2. Feed. Duck feed is fed regularly according to normal conditions and, if necessary, can be fed once more at night to prevent starvation. Do not feed too much feed to prevent overfilling and increase the burden on the stomach and intestines of ducks. The amount of fish feed can be properly determined according to the number of fish in the pond. For ponds with less fish culture, it is not necessary to add bait, but only rely on duck dung and residual feed in ponds with more fish; ponds with more fish should adhere to the principle of four fixed feeding, properly add artificial feed, and randomly adjust the feeding amount according to weather conditions, with no leftover as the principle.

3. Duck dung is put into the pond. The duck house and duck farm are cleaned regularly every day, and the amount of duck dung into the pool is determined according to the fat and thin of the pond water. in principle, the residual feed of duck can be swept directly into the pond for fish to eat, and the excess duck dung is accumulated and fermented, as appropriate. In this way, the environmental hygiene of fish-duck mixed culture ponds can be maintained and the water will not be polluted.

4. Disease prevention and treatment. Every 15 days, the water body is sterilized with quicklime and bleach. Duck houses and farms should be kept dry and cleaned frequently. When feeding, flumaric acid, carbendazim, gentamicin and other drugs can be added irregularly, and bait feeding can effectively prevent the occurrence of diseases. Fish disease, duck disease and other abnormal conditions should be diagnosed and treated immediately and prescribe the right medicine. Dead fish, sick fish and dead ducks should be fished out of mixed culture ponds at any time and buried deep away from the water surface to prevent the spread of germs.

5. Strengthen pond patrol. The mixed culture pond of fish and duck should insist on patrolling the pond, especially when the fish disease and duck disease are high and the temperature is high. The main purpose is to observe the water color and water quality, adjust the feed and the amount of duck dung into the pond according to the observation, maintain the frequency and interval of adding new water, observe the activities of fish and duck, find problems, and solve them immediately. The residual feed and dirt on the water surface are fished out in time to ensure good water quality.
