SHOULD PROBIOTICS BE USED IN SHRIMP PONDS DURING HOT WEATHER?
High temperatures also accelerate the decomposition of shrimp waste, leading to localized oxygen shortages at the pond bottom. Harmful gases such as H₂S, NO₂, and NH₃ build up, and harmful bacteria proliferate. Algae—especially blue-green algae (Cyanophyta) and dinoflagellates (Dinophyta)—tend to bloom rapidly, releasing toxins that are detrimental to shrimp health. As algae bloom and die off quickly, they destabilize the pond's pH levels and increase suspended solids in the water, deteriorating water quality.
Hot weather not only increases the water temperature in shrimp ponds but also triggers a cascade of negative impacts on shrimp health. Therefore, farmers must frequently monitor water quality parameters to detect anomalies early and respond promptly.
Controlling algae blooms in shrimp ponds is a critical task during this season to prevent worsening conditions.
Pond water with green algae bloom
To manage algae levels in the pond:
Perform water exchange with proper dosage and frequency
Use biological products that cleanse the water, improve water clarity, and reduce viscosity
Chemical algaecides may be used but are generally discouraged due to safety concerns.
