Understanding Dissolved Oxygen in Aquaculture

Dissolved oxygen (DO) is the single most critical water quality parameter in aquaculture. Fish depend on DO for respiration, and low levels lead to stress, reduced feed intake, poor growth, increased disease susceptibility, and mortality. DO levels fluctuate with temperature, salinity, atmospheric pressure, photosynthesis, and biological oxygen demand. Continuous monitoring and adequate aeration are essential for successful aquaculture operations.
