Mixed fish and duck can make reasonable conversion of water and maintain a virtuous cycle of substances. Ducks move in water to cool down and grow healthily. Fish can use the waste discharged from ducks to keep the water clean and provide quality consumer products. Diversification of fish and ducks must be based on the law, in particular to strengthen the aquaculture management, so as to bring benefits to farmers. Specific should do the following:
1, adjust the water quality. Due to the activities of ducks, the evaporation of fish and duck polyculture pool water is often relatively large, combined with the discharge of duck manure and residual feed, the water quality is very apt to deteriorate. Therefore, the fish-duck mixed-culture pool should always be treated with water and water to maintain the water depth. Above 1.2 meters, the water level should be kept stable. Try not to go up or down. In the hot season, the number of water changes should be increased, preferably once a day, to prevent the occurrence of hypoxia, floating heads and flooding. If the water quality is found to be changed, new water should be added immediately, or it can be treated with sprinkling oxygenation agent, water conditioner, etc., and temporary first aid.
2, feed feeding. The duck feed should be fed regularly according to normal conditions. If necessary, it can be fed once at night to prevent starvation. Feeds should not be fed too much to prevent over-saturation and increase the gastrointestinal burden. Fish feed can be appropriately determined according to the amount of fish. In a pond with few fish rearing, it is not necessary to feed bait. Only the duck manure and residual feed in the pool are sufficient for fish needs. For ponds with more fish, the principle of “quadriregulation†should be adhered to, and artificial feed should be added appropriately. According to the weather conditions, the amount of feeding is adjusted at random, and the principle is not left.
3, duck droppings into the pool. The duck house and duck farm should be regularly cleaned every day, and the amount of duck dung should be determined according to the thinning condition of the pool water. In principle, the residual feed of the duck can be directly swept into the pool for fish to eat. The excess duck dung is accumulated and fermented, and it is applied as appropriate. . In this way, the environmental hygiene of the breeding place can be maintained without polluting the water body.
4, disease prevention and treatment. Water should be disinfected and sterilized with quicklime, bleach and other drugs every 15 days. The duck and duck farms should be kept dry and cleaned. When feeds are fed, it is possible to add fluocic acid, flavomycin, gentamycin and other drugs to feed the baits, which can effectively prevent the occurrence of duck diseases and fish diseases. When fish diseases, duck diseases and abnormal conditions are found, the technicians should be invited immediately to perform on-site diagnosis and treatment. Dead fish, diseased fish and dead ducks should be fished out of the pond at any time and buried deep away from the water to prevent the spread of germs.
5, strengthen the tour pond. The fish-duck mixed-pool shall adhere to the system of touring ponds, especially in the seasons of fish disease, duck disease, and high temperatures. It is necessary to maintain two inspections, morning and evening, with the purpose of observing the water color and water quality. According to the observed conditions, Adjust feed and duck dung feed and pond intake, keep the number and interval of fresh water exchange; observe fish and duck activities, find problems, and solve problems immediately; timely remove residual feed and water surface pollution to ensure water quality Good; prevent theft and invasion of predators.
Mushrooms are one of the familiar "mountain treasures". To obtain this reputation, mushrooms are not only dependent on taste, but also related to their rich nutrition and excellent health care value. Mushrooms are very rich in minerals, and especially worth mentioning is potassium. Potassium prevents strokes, assists normal muscle contraction, and reduces hypertension. What we usually call a "potassium star" banana, the potassium content is 256 mg / 100 g, and the potassium content of common mushrooms are: Tricholoma (white mushroom) 1655 mg / 100 g, mushroom 312 mg / 100 g, Agaricus 307 mg / 100 g, far more than bananas.
