Abstract : Proper management of water quality variables in aquaculture operations, including those in dredged material containment areas, is imperative if success is expected. Dissolved oxygen, perhaps the most critical factor in fish culture systems, can be managed with mechanical aeration. Carbon dioxide may be harmful to fish when oxygen concentrations are low. Hydrated lime is effective in removing carbon dioxide from water. An imbalance between calcium hardness values and alkalinity concentrations may cause high pH levels lethal to fish. Ammonia and nitrite often accumulate in aquaculture systems. A pond treatment of sodium chloride protects fish from nitrite toxicity. Filter alum may be used to remove colloidal clay particles from water, eliminating turbidity that may limit photosynthesis.
