1. CAUSE OF DISEASE

White spots in the internal organs disease of snakehead caused by Aeromonas schubertii bacteria.

2. SIGNS AND CONDITIONS OF DISEASE

- Dark color fish, slow-response, rash, bleeding fins, anus, skin, gills, eyes and root (Figure 2).

- Hemorrhagic muscle, red, dark internal hemorrhage. Liver, kidney, spleen have many white pus spots, some cases appear on the fish's intestines (Figure 3).

- The disease appears mostly in the farming period, with strong outbreaks in the dry season, high temperature (January-April).

3. DISEASE PREVENTION AND TREATMENT SOLUTIONS

1. Disease prevention solutions

 - Improve pond water environment:

+ Periodically, water desinfection with GLUMAX (1L/4,000 - 5,000m3 of water).

+ Adding micro-organisms with VB-EM (5L/3,000m3 water) improves water quality and compete with pathogenic bacteria.

 - Increasing resistance for fingerling catfish:

+ Prevention of internal and external parasites, VB-SOL_new (1kg/15 tons of fish)

+ Periodically supplement, BIO-X_pro + VB12_pro (1Kg/L/10-15 tons of fish) to support digestion, enhance liver and kidney function.

2. Treatment solutions

- Case 1: Snackhead just have hemorrhagic disease and white spots in the internal organs disease

+ Using BIO-POND_pro to degassing toxic gases, suspended substances to clean the water environment.

+ Use GLUMAX to disinfect pond water.

+ Reduce the amount of feed (50%) and combine using VB-RIDO_01 + VIBOZYME new.

+ Using BIO-POND_pro to absorb toxic gases, suspended substances, clean the pond water environment.

+ Reduce the amount of feed (50%) and combine using VB-SOL_new (only the first 2 days) + VB-RIDO_01.

+ Use DE AGA to treat parasites after it is discharged into the water environment.
