Pond improvement
The main performance is: when the fish pond is hypoxic, the oxygenator can prevent the "floating head" of fish and shrimp. When the upper layer of dissolved oxygen is high on sunny days, it can accelerate the convection of the water body, improve the dissolved oxygen in the water body and the lower layer, which is conducive to the rapid growth of fish and shrimp, reduce the bait coefficient, promote the oxidation and decomposition of organic matter, and reduce the occurrence of diseases. In addition, the circulation of the water body also promotes the reproduction and growth of plankton and improves the primary productivity of the pond.

The role of the aerator is not only to increase the oxygen of the water body, but also to effectively promote the improvement of the primary productivity and self-purification capacity of the pond, thus improving the water quality and ecological environment of the pond. The water circulation flow generated by it is not suitable for the living habits of some cultured objects such as eel and shrimp, but it has a good effect on promoting the healthy and rapid growth of fish and shrimp.
