Moderate
Poor Aeration
Aeration is not just about oxygen — it also drives circulation that prevents stratification, releases harmful gases, and keeps solids in suspension for removal. Undersized or failing aeration is one of the most common, most fixable problems on a fish farm.
Symptoms & Signs
- Thermal or oxygen stratification between surface and bottom
- Persistent algae blooms and murky water
- Fish avoid certain areas of the pond
Common Causes
- Undersized aerator for pond volume and stocking density
- Diffusers clogged or placed too shallow
- No backup aeration for power outages
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.
