Why does aquaculture water body have hypoxia?

The negative impact of global warming and rapid economic and social development has worsened the water environment. Pollution of rivers, lakes and rivers, acid rain worldwide, the effectiveness of aquaculture technology, and the abuse of fertilizers, drugs, and antibiotics have also caused severe damage to the microbial environment. The destruction exacerbates the lack of oxygen in the environment.

Second, the majority of farmers have insufficient understanding of the impact of water hypoxia on the breeding environment and the breeding animals. They are limited to solving the floating head and pan pond level of farmed animals. They are still far from realizing that the lack of oxygen in water bodies can lead to serious environmental degradation and ecological degradation. This imbalance will affect the healthy growth and product quality of farmed animals, especially the farming of blue shrimp and river crab. Misunderstood that as long as the aquatic plants are well planted, crabs and shrimps can be raised.

What is not known is that aquatic plants, like all living things, can breathe at night and stop photosynthesis. Therefore, shrimp and crab breeding ponds are often in a state of hypoxia at night. At the same time, the principles, methods, advantages and disadvantages of various aerations are not well understood. In the process of use, there will often be halfway or even counterproductive consequences.
