What is oxygen depletion? (ufl.edu)
Oxygen depletion refers to low levels of DO and may result in fish mortality. (ufl.edu)
Sensitivity to low levels of dissolved oxygen is species specific, however, most species of fish are distressed when DO falls to 2-4 mg/L. Mortality usually occurs at concentrations less than 2 mg/L. The number of fish that die during an oxygen depletion event is determined by how low the DO gets and how long it stays down. (ufl.edu)

Oxygen depletion occurs when oxygen consumption exceeds oxygen production. (ufl.edu)
Why are oxygen depletion events most troublesome in the summer? (ufl.edu)
