Moderate
Monitoring During Hot Weather
Warm water holds less dissolved oxygen at exactly the moment fish metabolism (and oxygen demand) is highest. Summer is when most oxygen crises occur. Continuous temperature monitoring and proactive aeration are your best defenses.
Symptoms & Signs
- Morning DO readings near or below critical thresholds
- Fish gasping at dawn during summer
- Reduced feeding during the hottest part of the day
Common Causes
- Warm water holds less dissolved oxygen
- Higher metabolism increases fish oxygen demand
- Decomposition rates rise with temperature
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.
