Yes. Oxygen is not easily soluble in water, about 30ml of oxygen is dissolved in 1L of water, and the water in the pond is still water when fish are raised, and the oxygen content is not enough to support the daily consumption of fish.
Let the water circulate. It's okay to flow, but it's not as good as oxygen, because oxygen dissolves in very small amounts of water.
The principle of the oxygen pump is to press the air into the water, so that the oxygen in the air is in full contact with the water, so that the oxygen is integrated into the water, so as to increase the amount of dissolved oxygen in the water body, so as to ensure the growth needs of aerobic organisms.
Because of its convenient and efficient use and low cost, oxygen pumps are widely used in modern fish farming.
Oxygen is most widely distributed in nature, and the mass of the earth's crust is abundant.
The highest element. In the oxidation of hydrocarbons, the treatment of wastewater, rocket propellants.
and oxygen is needed for animals and humans to breathe in aviation, aerospace and diving. Animal respiration, combustion, and all oxidation processes, including the decay of organic matter, consume oxygen.
But the oxygen in the air can pass through the photosynthesis of plants.
Constantly being replenished. In the cutting and welding of metal. It is made with pure oxygen and combustible gas (such as acetylene.
mixing, creating a flame at extremely high temperatures, which melts the metal. Metallurgical processes are inseparable from oxygen. To fortify nitric acid.
and the production process of sulfuric acid also requires oxygen.
Oxygen and water vapor are used instead of air.
The mixture is blown into the gas gasifier to obtain gas with high calorific value. Medical gas is extremely important.

You have to have gas to get into the water. That's because there are many fish and not enough oxygen.

If there is circulating water, there is no need for oxygen.

Flowing water usually contains oxygen. Oxygen is one of the components of air and can be dissolved in water. When water flows, it comes into contact with oxygen in the air, causing oxygen molecules to dissolve into the water.
The amount of dissolved oxygen in water can be affected by a variety of factors, such as water temperature, pressure, and oxygen concentration in the surrounding environment, among others. Normally, flowing water will have a higher solubility of oxygen. This is because the flowing water is in full contact with the air, causing the gas exchange to be more frequent, thus increasing the amount of dissolved oxygen in the water.
Oxygen in water is very important for biological survival and ecosystem health. The oxygen in the water supplies the aquatic organisms for respiration and sustains their survival. For aquatic ecosystems such as rivers, streams, and oceans, flowing water provides more oxygen replenishment and maintains the ecological balance of aquatic life.
It is important to note that the solubility of oxygen in water is not constant and is affected by various environmental factors. For example, high temperatures, the presence of contaminants, and other factors can affect the oxygen content in water. Therefore, in some cases, hypoxia may occur in water bodies, which can have a negative impact on the health of aquatic organisms and the Cyclophyllum ecosystem.

The presence of oxygen in the water is dissolved oxygen, and it is not the water flow that has oxygen.
The molecular oxygen in the air dissolved in water is called dissolved oxygen, and the content of dissolved oxygen in water is closely related to the partial pressure of oxygen in the air and the temperature of the water. Under natural conditions, the oxygen content in the air does not change much, so the water temperature is the main factor, and the lower the water temperature, the higher the dissolved oxygen content in the water.
The molecular oxygen dissolved in water is called dissolved oxygen and is usually denoted as do, expressed in milligrams of oxygen per liter of water. The amount of dissolved oxygen in the water is an indicator of the self-purification ability of the water body.
There is oxygen in the water, of course. Fish and other creatures in the water live by breathing oxygen from the water, but their respiratory organs are different from those of us humans. Fish, for example, generally use their gills to breathe. >>>More
