1. Pond aerator to improve pond
Mainly manifested in: when the fish pond is hypoxic, the aerator can be used to prevent the "floating head" of fish and shrimp. When the upper dissolved oxygen is high on a sunny day, it can accelerate the convection of the water body and increase the dissolved oxygen in the middle and lower layers of the water body, which is beneficial to the rapid growth of fish and shrimp, reduces the feed coefficient, promotes the oxidation and decomposition of organic matter, and reduces the occurrence of diseases. In addition, the circulation of the water body also promotes the reproduction and growth of plankton and increases the primary productivity of the pond.
It can be seen that the role of the aerator is not only to increase oxygen to the water body, but also to effectively promote the improvement of the primary productivity and self-purification capacity of the pond, thereby improving the water quality and the ecological environment of the pond. The water circulation produced by it is not suitable for the living habits of some cultured objects such as eels and shrimps, but it has a good effect on promoting the healthy and rapid growth of fish and shrimps.
2. Pond aerator shrimp farm configuration
The configuration of the aerator is mainly determined by the water source condition, the breeding density, and the total energy consumption of the intake and drainage.
Water source status: Whether the water source is abundant and whether the water quality has been maintained in good condition; if the water quality is good, consider using less, and vice versa, changing more water only when the water quality is good.

The aquaculture density is the yield per mu: high yields more, and low yields less.
Drainage energy consumption situation: If the energy consumption of the inlet and outlet is less, the aerator can be considered less equipped; the energy consumption is larger, and the amount of configuration should be larger.
Economic analysis: Consider the relative ratio of electricity bills and shrimp prices. If the local electricity bill is relatively high and the price of shrimp is relatively low, consider less allocation; otherwise, more allocation.
