October weather starts to turn cooler water temperature gradually decreased the occurrence of the National Aquaculture Disease will be relatively reduced, especially the the Northern Aquaculture Disease high incidence period has expired, the most farmed species into the harvest period and pool into the winter period. But in the south, the aquaculture water water temperature gradually decreased, the temperature difference between day and night, to go through a growth of more than six months, the increase in the storage pond, farmed aquatic animals, aquaculture water quality declined, and created favorable conditions for the breeding of pathogens, some The species may peak incidence around still attaches great importance to the prevention and control of aquatic animal diseases. At the same time, in most parts of the country, October is also a fish wintering growth before last month, should be strengthened feeding and water management, pay close attention to changes in the weather, and take effective measures to do late feeding and management of fish and wintering Ready to work.

Prevention and control measures recommended

(A) preventive measures

. Strengthen aquaculture water quality management, to maintain a good breeding environment, the prevention of the occurrence of disease. Water temperature changes in October exacerbated by increasing changes in water quality, farmed animals could easily lead to stress, the breeding water level should remain deepest fed high-quality feed, regular disinfection of aquaculture water disinfection preparations, probiotics regulate water quality, timely start aerobics machine, timely removal of the bait to improve the water quality of aquaculture water, to prevent the occurrence of various diseases.

2. Strengthen management insisted Xuntang prevention floating head and Pan Tong.

Most parts of the country, October is the last growing season before winter breeding animals, to strengthen nurturing; unit area is relatively large storage pond, the water quality perishable. To do so, we must pay close attention to changes in the weather, strengthen Xuntang and timely change the water aerobics, to prevent breeding animals from lack of oxygen caused by the floating head and pan-ponds phenomenon.

3. Timely harvesting and standardizing operations, good wintering preparations.

In the the wintering process of harvesting listing and pond in, be careful operation, avoid breeding animals injured; pond disinfection and disinfection of breeding animals to do before breeding animals into the winter pool, and raise the water level for the breeding animals wintering good fully prepared.

(B) treatment

This section relates to the fishery drugs are GB fishery drugs, aquatic animals class practicing veterinary guidance, to be used in accordance with the specification requirements. Promote ecology, health, breeding, no or little medication, to avoid the risks of drug residues.

Bacterial disease: can be improved water quality, Quanchiposa disinfectants and the bait mixed feeding sensitive antimicrobial drug combination treatment. Disinfectant, as farmed species and incidence optional chlorine lime, povidone-iodine solution, of trichloroisocyanuric acid powder, BCDMH powder, sodium hypochlorite solution, benzalkonium bromide solution one. Should be carried out prior to the selection of the antimicrobial drug susceptibility testing.

Parasitic diseases: protozoosis to depending on the farmed species incidence optional sulfate, zinc powder, zinc sulfate trichloroisocyanuric acid powder, copper sulfate ferrous sulfate powder, hydrochloric acid Robenidine powder, ground grams Diclazuril premixes one; helminthiasis depending on breeding varieties and morbidity can choose one of albendazole the powder, soft gliquidone of premixes, mebendazole solution, refined trichlorfon powder.
