Improve the pond
Mainly manifested in:
When the fish pond is lack of oxygen, the aerator can be used to prevent the "floating head" of fish and shrimp. When the upper layer of dissolved oxygen is high on a sunny day, it can accelerate the convection of the water body, increase the dissolved oxygen in the middle and lower layers of the water body, which is conducive 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 the oxygen of the water body, but also to effectively promote the improvement of the primary productivity and self-purification ability 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.
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 water in and out.
Water source status: Whether the water source is abundant and whether the water quality has been maintained well; if the water quality is good, consider less allocation, otherwise, more allocation and change 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: 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, then consider less allocation; otherwise, more allocation.
It is the world’s largest fishery production. In the past two decades, fishery production has been among the top in the world. The total output value of domestic fishery has accounted for 10% of the total agricultural output value. Medium aquaculture has gradually developed in the direction of high density and intensification, and the total aquaculture production has increased year by year. This is inseparable from the gradual realization of mechanization in the aquaculture industry, especially the widespread use of aerators.
