PREVENTION AND TREATMENT OF BLACK SPOT DISEASE IN SHRIMP

Black spot disease in whiteleg shrimp can appear from 20–90 days old, and is particularly common when shrimp are 25–45 days old. The disease often breaks out during seasonal transitions, when abrupt weather changes cause shrimp to be easily stressed and the pond environment becomes imbalanced.

PREVENTION AND TREATMENT OF BLACK SPOT DISEASE IN SHRIMP

Causes of Black Spot Disease in Shrimp

  • Water environment: High organic matter, toxic gases, high opportunistic bacteria.
  • Vibrio and shell-fouling fungi: Attack the epidermis, causing damage and black spots.
  • Lack of trace minerals and beneficial probiotics: Poor molting in shrimp, shells are easily damaged and susceptible to disease.
  • Poor pond management: Fluctuations in pH, alkalinity, and oxygen weaken shrimp.

Solutions:

  • Disinfect to reduce pathogens:

Morning: Vibrio Clear, Evening: Aquadine New.

  • Introduce beneficial probiotics:

The next day, use SoilMax/Bacwat to restore the microbial system.

  • Maintain long-term prevention:

Use Soilmax/Bacwat periodically to stabilize the pond bottom and prevent Vibrio outbreaks.

  • Supplement minerals and environmental management:

Maintain stable pH, alkalinity, and oxygen to support healthy molting in shrimp.
