Shrimp Pond Water Quality

VIRKON™ AQUATIC – FORMULATED DISINFECTION POWER

Not all disinfectants are effective against the wide range of viral, bacterial and fungal disease-causing organisms that affect shrimp, especially within harsh pond environments. Even disinfectants with similar chemistry can have widely different spectra of activity and effective dilution rates. Selecting the correct disinfectant for shrimp production biosecurity is therefore critical for effective disease prevention and control.

Virkon™ Aquatic has been independently proven to be highly effective and rapidly kills major shrimp disease-causing organisms in variable water conditions including, White spot syndrome virus (WSSV), Vibrio harveyi, Vibrio parahaemolyticus, and Taura syndrome virus.

Virkon™ Aquatic does not negatively impact the shrimp’s food source, phytoplankton, or leave residues of concern within the shrimp itself.

DISINFECTANT DEGRADATION RATES

Some disinfectants, whilst effective against pathogens, can have a negative residual toxic effect on developing shrimp, due to their inability to degrade rapidly within water.

In simple terms, Virkon™ Aquatic effectively kills the shrimp disease-causing organisms and then rapidly degrades leaving no residue of concern. Other disinfectant technologies take longer to eliminate the pathogens and leave harmful chemicals in the water.

The graphs below clearly demonstrate the rapid degradation of Virkon™ Aquatic, when compared to Calcium Hypochlorite (Under test conditions designed to simulate a shrimp pond environment), over a 7-day period from the initial introduction of the disinfectant to the shrimp pond water.

DEGRADATION RATE IN SHRIMP POND WATER

VIRKON™ AQUATIC FOR CONTINUOUS POND WATER BIOSECURITY

Disinfect the newly prepared and refilled pond water with Virkon™ Aquatic at a dilution rate of 1.2ppm – 2ppm one day before post larvae stocking.

Shrimp disease-causing organism counts can be kept below the maximum acceptable threshold of 103 (CFU/ ml) by adding Virkon™ Aquatic at 1.2 ppm to the pond at 7-day intervals from day one, and throughout the remaining production cycle.

Use a mechanical filtration system to help remove large particular matter during the production cycle; this will help improve and maintain water quality.

Ensure standard continuous disinfection biosecurity procedures are adhered to as part of the overall pond water management process.

These include:

  • Disinfectant foot & wheel dips
  • Boat and vehicle disinfection
  • The disinfection of movable equipment & tools
  • Hard surfaces (path & roadways)
