First, fertilize and promote strong. In autumn, the aquaculture subject relatively slows individual growth and supplies, mainly to meet the body's energy storage, and timely feeding of concentrate feed can meet the needs of farmers. Not only can it increase production, but it can effectively increase the export specifications and aquaculture benefits of aquatic products, such as Crabs currently need to increase the proportion of animal feed to increase their paste yellow, fish, shrimp should increase the delivery of concentrate, fertility and promote strong, reduce the loss of some species such as the mortality of the shrimp. Second, control the water quality. The temperature difference between morning and evening after the fall will be relatively large, it will easily lead to lack of oxygen floating head, pan pool will occur. Therefore, the transparency of the autumn water quality control in the 30 to 35 cm, pH 8.0 to 8.5, the breeding density is too large, the water is not ideal for the day to do a good oxygen increase in the evening, to strengthen the tour pond. Third, science and disease prevention. Autumn is the second highest period of aquaculture disease, mainly ectoparasite and bacterial diseases. It is advisable to use 1-2 times insecticides and one bactericidal drug for Pustsch, and to prevent fish disease by combining internal medicines that improve the immune system against diseases such as immune polysaccharides, VC, and allicin. Shrimp and crab ponds should reasonably control the density and distribution of aquatic weeds. The fish should be fished out as soon as possible and surplus and easy to die, reducing the diseases and oxygen consumption caused by decay of aquatic plants. Fourth, strengthen Xuntang. After September, it is necessary to step up the inspection of the ponds to remove the remaining foods in time, and pay attention to the anti-escape facilities, the anti-escape facilities at the entrances and exits, and whether there are loopholes in the escapeable breeding species such as river crabs and soft-shelled turtles. In the evening, the escape prevention and anti-theft inspections shall be strengthened. Fifth, timely listing. The time-to-market and progress of the sale should be based on factors such as the amount of fish (shrimp) in the pond, the temperature of the catch water, and the production schedule for the next year. Some species such as squid and Californian squid have reasonably controlled the amount of bait and storage pond density, slowed their growth, and started to go public before and after next year's Ching Ming.
