Improvements to the pond
When the fish pond is deficient in oxygen, turn on the aerator, which can prevent the fish and shrimp from "floating head". When the upper layer of dissolved oxygen is high on sunny days, 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 bait coefficient, promotes the oxidative decomposition of organic matter, and reduces the occurrence of diseases. In addition, the circulating 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 function of the aerator is not only to increase the oxygenation of 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 ecological environment of the pond. The water circulation flow produced by it is not suitable for the living habits of some aquaculture objects such as eels and shrimps, but it has a good effect on promoting the health and rapid growth of fish and shrimp.
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 intake and drainage.
Water source status: whether the water source is abundant, and whether the water quality has been maintained in good quality; if the water quality is good, less allocation can be considered;
Breeding density is the yield per mu: if it is high, it will be more, and if it is low, it will be less.
Drainage energy consumption: If the energy consumption of water intake and drainage is low, the aerator can be configured less; if the energy consumption is large, the configuration amount should be large.
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, allocate more.
