Preparing shrimp farms for wet weather

Preparing shrimp farms for wet weather


Rain presents a major challenge for shrimp farming. When the rainy season arrives shrimp production will naturally reduce.


Some recommendations are from Alune.



  • Use weather forecasts to monitor local weather conditions
  • Ensure that all aeration equipment and the electricity set-up is in good working order
  • Ensure your farm has drainage pipes that would allow surface water to be discharged or flowed out properly
  • It may be necessary to have power generator ready in case of power outage due to severe rainfall.


Countermeasures during the rain

  • Ensure all aeration equipment is working properly to maintain acceptable DO levels, ideally above 5 ppm
  • If possible, flow out the surface water to prevent significant salinity drop
  • Regularly monitor key water quality parameters, such as DO, pH and alkalinity
  • Apply CaO, CaCO3, or CaMg(CO3)2, or other treatment to increase alkalinity
  • Reduce feeding rate and monitor pond conditions. Adjust the feeding rate accordingly

Measures after the rain

  • Ensure aeration is maintained
  • If salinity drops below optimal levels, add new treated seawater (depending on your water condition)
  • Administer probiotics to increase decomposition and nitrification rate. This will also inhibit the growth of pathogens
  • Increase feeding rate in accordance with key parameters like temperature, pH and DO
  • Sample the pond to estimate the shrimp populationand to detect any mortality events
  • Apply minerals to counteract dilution effects
  • Check water samples collected near the pond bottom to monitor the bacterial count. Use TCBS agar plates if available or send the samples it to your local laboratory.
  • If you haven’t already, implement a regular pond cleaning routine. Siphon the pond bottom to reduce organic matterand dead phytoplankton.

Hopefully above information are helpful for pond management. For paddlewheel aerator inquiry, kindly do contact us through email at  or phone call.
