1. Control the water source, change the water, change the water, and maintain good water quality. Strict dredging and disinfection of the pond that occurred over the blood, to eliminate residual pathogenic aerobic bacteria.

2, reasonable stock, control too high stocking density. The density is too large, the stress effect of the fish is large, and it should be excised to induce the disease.

3, use physical fitness seedling or disease-resistant seedling, or immunize soaking, injection. 4, use high quality feed, give the bait to regulate, quantitative, positioned, and timed.
5, regularly check the fish, eliminate weeds, bait, deadfish and parasitic intermediate hosts in the pool, and prevent the disease and spread.
