Scale explosion disease in koi fish is mainly caused by Pseudomonas punctata infection. Pseudomonas punctata is a conditional pathogen. Conditional pathogens are bacteria that may cause diseases under certain conditions. The normal flora in this fungus may cause disease when its aggregation site changes and the body's resistance decreases. So we should also strengthen the resistance of koi fish when breeding in koi fish.

Treatment of fried fish scales in koi fish;

1, you can use saline bubble, and the treatment effect is still very good, just like the treatment of congestion.

2. Furacillin can be used for treatment. Dissolve 1g furacilin in 10kg water and soak the fish for about 20 to 30 minutes.

3. Gentamicin can also be treated. Choose 3 to 5 gentamicins, dissolve them in 65,438+00 kilograms of water, and soak the fish for 65,438+00 to 65,438+05 minutes, or soak the fish with 0.02 salt solution and 0.02 sodium bicarbonate solution for 65,438+00 to 65,438+05 minutes.

4. Strengthen the pre-winter work in koi fish, shorten the fasting period in koi fish as far as possible, and feed some live bait such as Daphnia and earthworm after the water temperature rises in early spring, so as to enhance the resistance of koi fish and reduce the occurrence of this disease in koi fish.
