As we all know, if the fish in the aquarium lack oxygen. It can be saved by blowing air into the water with a straw. What about the high-density fish pond if it is lack of oxygen? It is certainly useless to use this method again! Especially in summer, when it is hot and cloudy, if the fish lack oxygen, the consequences will be very serious. For example, in June this year, Tiktok reported many cases of farmers who "turn sugar" due to lack of oxygen! Caused a loss of more than 500000 yuan! It can be said that once it returned to the "pre liberation"!
Then, the fish in the fish pond lack oxygen! Is there no quick remedy?
Yes, there must be!
Today, let's discuss how to quickly remedy the lack of oxygen in fish!
First aid methods for anoxic fishpond
1、 Biological slow oxygen replenishment
1. Fish pond filling with fertilizer and water
Pour the water with relatively fat water into the fish pond, and add the pond fertilizer water, which is conducive to the growth of phytoplankton. Through photosynthesis, it can effectively improve the dissolved oxygen in the pond.
2. Apply organic fertilizer
Applying organic fertilizer to the pond can promote the growth and reproduction of plankton, thus increasing the photosynthesis of the water body and effectively improving the dissolved oxygen in the pond. When applying organic fertilizer to the pond, apply fertilizer according to the proportion of 200kg decomposed organic fertilizer per mu.
3. Pour wine quicklime
Sprinkle secondary lime on the pond every 20 days, and sprinkle it according to the proportion of 1m per mu of water depth and 10kg of quicklime. Quicklime has the effect of clarifying the water quality and improving the transparency of the water body, so as to increase the amount of sunlight entering the water body, which is conducive to improving the light cooperation ability of the water body.
2、 Rapid oxygen replenishment of mechanical equipment
1. Take circulating water injection measures
Connect the two fish ponds that are relatively close to each other with cement pipes at the corner of the fish pond, and pump the water in the pond to another pond mechanically at the other corner, so as to form the water circulation of the two fish ponds. The main principle is that the increase of the contact surface between the water body and the air makes the oxygen in the air dissolve into the water body, which improves the dissolved oxygen in the water body.
2. Stir the pond bottom regularly
Agitate the pond water up and down, which is conducive to the transportation of dissolved oxygen from the upper water body to the lower layer, and improve the dissolved oxygen in the lower water body to make up for the lack of dissolved oxygen in the lower water body. The annular fans, roots fans and submerged fans produced and sold by our company can stir the pond bottom and quickly supplement the dissolved oxygen in the water! Among them, if the fishpond area is less than 5 mu and the water depth is less than 2 meters, please choose the annular fan to cooperate with the self sinking pipe or aeration plate to increase oxygen! If the fishpond area is more than 5 mu or the water depth is more than two meters, please choose submerged fan or Roots fan for rapid oxygenation! This way of increasing oxygen can not only rapidly increase oxygen, but also help improve the water quality of fish ponds! The following two pictures are the cases of using the fans produced and sold by our factory to oxygenate the fishpond!

The above is the method of [first aid for anoxic fish pond] shared by roots blower manufacturer Shanghai Ruizhe environmental protection! I hope this method can help you breeding bosses! Friendly tips: aquaculture should not only ensure the dissolved oxygen in water! And we should always pay attention to the water quality of fish ponds!
