Problems solved by technology
The most common oxygenation method is mechanical pump oxygenation, which requires a large investment and consumes a lot of energy, and the oxygenation is only on the surface of the water area; at present, people generally use chemical oxygenation agents to be thrown into the pond, and the existing chemical oxygenation agents are generally excessive. Oxides, which react with water to form oxygen
However, the existing oxygen enhancer is a powder, which reacts immediately after being thrown on the water surface, and its effect is similar to that of mechanical oxygen increase. Or, although some oxygen enhancers are not powdery, they can sink into the water or even the bottom of the water, but they react quickly and can only last. Oxygen is released in ten minutes, and the oxygenation effect and efficiency of fish and shrimp are not obvious

Embodiment Construction
[0010] best practice
[0011] The preferred embodiments of the present invention are described below.
[0012] 92 kg of sodium percarbonate was used as the chemical oxygen enhancer, and 8 kg of dextrin was used as the starch adhesive, and the two were fully and uniformly mixed into a mixture of 100 kg. Then put the mixture into the tabletting die of the tablet press. There are many small concave grooves on the surface of the tabletting die. After the mixture is pressed, it is a granular oxygen enhancer. The finished product is obtained by drying the granulated oxygen enhancer naturally.

Description
technical field [0001] The invention relates to the field of fishery (cultivation) additives, in particular to an oxygen enhancer for increasing the oxygen content in aquaculture waters and a preparation method thereof. Background technique [0002] With the continuous improvement of aquaculture technology and aquaculture costs, in order to pursue high yields, the amount of fish and shrimp stocked per unit water area is also increasing. However, high-density farming can easily lead to low oxygen content in aquaculture ponds, especially in areas where fish and shrimp are more concentrated at the bottom of the pond, which can cause suffocation and death of fish and shrimp, especially in hot weather. Therefore, farmers will increase oxygen in the pond within a certain period of time. The most common oxygenation method is mechanical pump oxygenation, which requires a large investment and consumes a lot of energy, and the oxygenation is only on the surface of the water area; at ...
