The July-September hot season is the golden season for fish growth and the peak period for fish disease. Therefore, we must strengthen the management of ponds, adhere to the principle of prevention, and comprehensive prevention and control in order to effectively control the occurrence and prevalence of fish diseases.
1. Water disinfection. The quality of the water environment directly affects the health of fish. Therefore, regular water disinfection is required. Every 15 days bleaching powder lppm, quicklime 20ppm and copper sulfate 0.7ppm alternating Quanchiposa once.
2. Food field disinfection. Fish ponds fed feed often cause the deterioration of water quality and the proliferation of germs because the remaining feed is not cleared. In the epidemic season of fish disease, besides diligent food, 0.25 kg of bleaching powder and 15 kg of water are used every month to splash around the food market.
3. Feeding baits. In the seasons of bacterial gills and gut inflammation of grass carp and catfish, it is necessary to feed medicine baits every week for prevention. At present, a simpler method is to add 0.5 kg of garlic and 1.0 kg of salt to 100 kg of feed, and add 10 g of sulfonamide to make the bait and feed it for 5 days for 5 days. In addition, loose sticks (10 kg/mu) can be bundled and soaked in fish ponds or sprinkled with buckwheat twigs (30 kg/mu). The prevention of fish diseases with maple leaves, iron leeks, and spicy leeks also has certain effects.
4. Change water regularly. Every 15 days, the pool water will be drained off and fresh water will be injected. This will not only increase the oxygen in the water, prevent fish from floating, but also improve the water environment and reduce the content of parasites and pathogens in the water.
