Fish farming is a common agricultural production and a good project for rural areas to adjust their industrial structure and increase farmers' income. However, there is a significant risk in the production process of this project, which is that fish ponds are prone to oxygen deficiency. When oxygen deficiency occurs in fish ponds, it can affect the growth of fish in the pond, and in severe cases, it may lead to serious consequences such as "flooding" of the fish pond. After the occurrence of oxygen deficiency in the fish pond, using an "aerator" to artificially aerate the pond is a more effective way to solve the problem of oxygen deficiency in the pond.

The "impeller type aerator", "waterwheel type aerator", and "water jet type aerator" mentioned by the questioner actually have similar oxygenation effects as long as their power is the same. Because their principle of adding oxygen to fish ponds is to stir the water, increasing the contact area between the water and the air, thereby allowing more and more oxygen in the air to dissolve into the water and effectively volatilize toxic and harmful gases in the water, thus solving the problem of fish hypoxia in the water.

In fact, these common aerators all have certain shortcomings, such as not being suitable for fish ponds with large areas and deep water levels; When the fish pond is severely lacking in oxygen, the aerator is only turned on, and the effect of oxygenation is not very obvious; Easy to cause electric leakage accidents, etc. So what kind of oxygenation equipment is better for fish ponds when experiencing hypoxia?

Of course, no matter how good the artificial oxygenation facilities or methods are, they cannot keep the water in the fish pond healthy and maintain high-quality water quality, which is commonly referred to as keeping the water "plump, lively, tender, and refreshing". This not only allows the fish in the fish pond to have more abundant natural bait, but also reduces the risk of oxygen deficiency in the pond. To maintain or control the fertility of the pond water, it is necessary to fertilize or plant aquatic plants. And by adding new water and replacing old water; Alternatively, chemical agents, biological regulators, etc. can be applied to achieve this.

In addition, to prevent oxygen deficiency in fish pond water, the most crucial thing is to have a reasonable stocking density and a reasonable variety combination, especially the proportion of filter feeding fish (silver carp and bighead carp). In short, to solve the problem of oxygen deficiency in ponds, the three types of aerators mentioned by the questioner have similar oxygenation effects under the same power. Therefore, in my opinion, to solve the problem of oxygen deficiency in ponds, we can consider using manufacturers of Qiantang aerators and improving the water quality of ponds.
