Water-Quality Changes After Rain
Heavy rainfall is one of the most underestimated events in pond aquaculture. It dilutes salinity, crashes pH, flushes in nutrients that feed algae blooms, and can introduce agricultural chemicals. Post-rain monitoring is essential.
Symptoms & Signs
- Sudden drop in pH and salinity after storms
- Algae bloom or crash within days of rainfall
- Fish going off feed after heavy rain
Common Causes
- Watershed runoff introduces nutrients and sediment
- Large freshwater volume dilutes dissolved salts
- Agricultural chemicals carried in from adjacent land
Species & Temperature Context
Water-quality parameters vary significantly by species, water temperature, production system, and local regulations. The ranges shown throughout this site are general guides based on common aquaculture species (tilapia, catfish, shrimp, trout). Always verify parameters for your specific species with a local aquaculture extension service or research institution before making management decisions.
