How to prevent autumn plague in fish? Getting the eight key points right is crucial
Eight key points for preventing "autumn plague" in fish
In autumn, fish are highly susceptible to acute diseases with extremely high mortality rates, such as flaccid atrophy disease, small claw worms, gill rot disease, and water mold disease, commonly known as "autumn plague." To prevent and treat "autumn plague" in fish, eight key points should be followed.
1. Improve the ecological environment. Pay attention to ecological prevention and control, appropriately feed full-price concentrated feed, tender grass, etc., start feeding early, and meet the nutritional needs of fish growth as much as possible to improve their immunity.
2. Actively add fresh water. Adding fresh water can bring in oxygen and various nutrient elements, such as iron, manganese, silicon, etc.; it can also dilute organic matter and toxic biological metabolites in the pond water, which is more conducive to disease prevention.
3. Control the water level as much as possible. When pond water is needed to irrigate crops, efforts should be made to maintain a water level of 70-80 cm in the pond.
4. Purify water quality with chemicals. Applying chemical agents to the pond to purify and improve water quality can reduce the breeding of fish diseases. Such as superphosphate, trichlorfon, copper sulfate, bleaching powder, etc.
5. Strengthen deworming of fish bodies. External parasitic diseases of fish are predisposing factors for many diseases. Observation must be strengthened to achieve thorough deworming and eliminate the harm of various complications.
6. Appropriately add medicated bait. Regularly add appropriate amounts of "Yujianling", salt, etc. to fish feed to enhance the ability of fish to resist diseases.
7. Avoid carp stirring. In ponds with a relatively large number of carp, correspondingly add concentrated feed to try to keep the active carp full and lazy, avoiding muddying the pond water.
8. Neutralize the pH. In autumn, ponds are often acidic, and in acidic environments, fish have slowed metabolism, reduced feeding, poor digestion, and weak disease resistance. Therefore, quicklime should be regularly applied in appropriate amounts to neutralize the pH.
