WebAug 20, 2024 · Dissolved oxygen management is the most important aspect of aquaculture pond water quality management. Dissolved oxygen concentration below 3 mg/L are stressful to shrimp and most warmwater fishes and result in lower survival and production. Concentrations below 1.0-1.5 mg/L for a few hours can kill warmwater animals. WebIn the open ocean photosynthesis can occur to an average depth of ______ m. 150-200 m.
