Nowadays, more and more people like to keep fish. Some people think that it is better to keep fish in autumn. So, what are the aspects of the experience of raising fish in autumn? Next, let's take a look at what the pet editor said.

Clear ponds and fertile water, according to the analysis of a large number of cases in recent years, the main reason for the increase of fish diseases during the high temperature period in autumn is due to excessive organic matter in the water body, resulting in poor water quality. To this end, it is necessary to insist on using quicklime to clear the pond every year, and insist on not using or using less organic manure. In spring, when the water quality is thin and the water body transparency is large, nitrogen fertilizer and phosphorus fertilizer can be used to adjust the water. In the case of high water temperature in summer and autumn, such as sudden changes in water quality, death of algae, and increased transparency of water bodies, nitrogen fertilizers must not be used to fertilize water. Turn on the aerator to reduce the content of organic matter, ammonia, nitrogen and nitrite in the water, and at the same time prolong the time of using the aerator.

Change the traditional treatment method. In terms of fish disease prevention and control, the traditional method is to use the method of killing insects first, then disinfection, early prevention without disease, and early treatment with disease. In the case of high temperature in summer, this method is not only impractical, but also often causes the water quality to deteriorate. Environmentally-friendly substrate improvement drugs and oxygen-enhancing drugs are often used to adjust the water quality, and an aerator is added during the day, even if there is an outbreak of fish disease, it must be Treated with water transfer and oral medication. The prevention and control of fish diseases in high temperature seasons should not be used in large areas to prevent water quality changes and aggravate the disease. The cause should be investigated. When feeding fish, an appropriate amount of drugs should be dissolved in water and then sprinkled near the feed table to form a medicated bath environment. It is better to use the main service, supplemented by the disinfection of the food court, combined with the treatment method of water transfer. 养殖密度要科学合理，池塘的水质在有机质污染和自净能力相平衡的情况下是稳定的，当养殖密度上升，鱼类排泄物增多，有机质污染量超过池塘自净能力时， The water quality is unstable and easily deteriorated, and fish diseases increase. Therefore, the breeding density should be scientific and reasonable, so that the self-purification capacity of the pond and the amount of organic matter pollution are basically balanced. Choose high-quality feed. In the whole breeding process, high-quality feed should be selected to increase the fish's own resistance, reduce fish excrement, and promote the healthy growth of fish. On the one hand, high-quality feed with moderate protein, good amino acid balance, and excellent processing technology should be selected; on the other hand, the feeding amount should be controlled, and the fish should be fed until 80% full. In the event of fish disease, one is to feed bait, and the other is to reduce the feeding amount to 60%. No feed containing harmful substances and various hormones. Adding vitamin C to the feed, about 300 grams per ton of feed, can improve the ability to resist stress and disease.

Strengthen the ability to resist stress. The high water temperature in autumn reduces the digestion and absorption rate of the fish, the growth rate of the fish slows down, the physiological metabolism is poor, and the anti-stress ability decreases. For ponds with inflow and drainage conditions, well water can be added to the pond before or after the aerator is turned on at noon, and the upper layer of high-temperature water can be discharged from the other side of the pond; in ponds without water inlet and drainage conditions, water hyacinth, float Ping and other aquatic plants can cover 1/10 of the water surface, which can not only degrade the organic matter, ammonia, nitrogen and nitrite in the water, but also reduce the water temperature. Change the feeding time to before 11:00 am and after 4:00 pm, avoid the time when the surface water temperature is high at noon, and reduce the energy consumption and stress response of the fish.
