The productivity of a pond depends on various factors, from water quality to oxygen levels. The pond needs to be constantly maintained, cleaned, and cared for in terms of its flora and fauna.
As is known, many people ask the question: “How can we keep fish under the ice?” Most fish farmers believe it is necessary to clear the snow so that the sun can revive the pond vegetation, which produces oxygen. However, just a few cloudy days can cause the pond plants to die again. Simply making holes in the pond won’t saturate the water with oxygen either, as they quickly freeze over. Holes can only be beneficial to the extent that light reaches the water through them. The best solution for keeping fish alive in winter is water aeration (oxygen saturation).
In summer, aerators are used for oxygen saturation of water when there is insufficient oxygen in the water. In winter, aerators help fish survive—they are used for water ventilation in carp farming areas, and most importantly, they are used for air saturation in water bodies.
How do aerators work?
- Water aerators blow a large amount of tiny air bubbles into the water at a regulated height (0.5 to 2 meters).
- By swirling, it mixes air and oxygen into the water.
- At sufficient depth, aeration neutralizes contaminating elements.
- The aerator ensures better oxygen delivery to the water. It can supply pure oxygen without dispersion at distances ranging from 0.5 to 8 meters.
- The aerator removes harmful gases from the water.
- By creating a horizontal water current and a vertical air flow in the water, the aerator prevents all types of stratification, preserving a stable ecosystem.
- The water aerator prevents the formation of gas pockets.
- Depending on the size of the pond, the power of the aerator and the air blower are selected. For example, a 60 W membrane air blower can deliver about 60 liters per minute of air.
Pastaba: Note: To effectively save fish, action is needed when the oxygen level drops to no less than 2.5 mg/l. After that, it may be too late. Additionally, the results will be positive only in small bodies of water of a few ares or hectares. In lakes that cover hundreds of hectares, increasing the flow rate may be the only effective measure.
