What are the basic uses of aerators?
Improvement to pond
Mainly manifested in:
When the fish pond is short of oxygen, turn on the aerator to prevent the "floating head" of fish and shrimp. Start up when the dissolved oxygen in the upper layer is high on a sunny day, which can accelerate the convection of the water body, increase the dissolved oxygen in the middle and lower layers of the water body, facilitate 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 cyclic flow of the water body also promotes the reproduction and growth of plankton and improves the primary productivity of the pond.
It can be seen that the role of aerators not only aerates water bodies, but also effectively promotes the improvement of primary productivity and self-purification capacity of ponds, thereby improving pond water quality and ecological environment. The water circulation flow produced 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.
Shrimp farm configuration
The configuration of the aerator is mainly determined by the conditions of water source, breeding density, total intake and drainage energy consumption, etc.
Water source status: Whether the water source is abundant and whether the water quality has always been good; if the water quality is good, you can consider less allocation, otherwise it is more, and only change the water when the water quality is good.
The breeding density is the yield per mu: the higher the more, the lower the less.
Drainage energy consumption: If the energy intake and drainage energy is less, the aerator can be considered less; the energy consumption is large, and the configuration should be large.
Economic analysis: Consider the relative ratio of electricity price and shrimp price. If the local electricity price is relatively high and the shrimp price is relatively low, consider less allocation; otherwise, more allocation.
