Oxygen Depletion in Ponds

Fish ponds may experience a loss of oxygen at any time of the year, depending on the weather and amount of nutrient enrichment the pond has received; however, most oxygen depletions occur in warm weather and usually follow a period of cloudy, overcast conditions. Low oxygen concentration in pond water means stress and possibly death for the pond fish. When fish die from low oxygen, there can be serious financial consequences for commercial fish operations; for example, largemouth bass, bream and grass carp can be worth more than $3,000.00 per acre. Therefore, pond owners should consider a plan to provide aeration for their ponds before oxygen depletions occur.
