Cold boiled water is water that has been heated. The temperature of boiled water is very high, and the solubility of gases decreases, that is, a lot of oxygen escapes to breathe and absorb oxygen, but there is less of it. oxygen, so the fish cannot survive normally. After high temperature, water also kills some microorganisms, and fish also need to absorb nutrients, so fish cannot be raised in cold boiled water.
So the answer is: you can't raise fish; cold boiled water contains less oxygen and does not contain enough microorganisms, so you cannot raise fish in cold boiled water.
Cold water is not suitable for fish farming.
During the process of boiling water, as water molecules vaporize, gases dissolved in the water (including oxygen, dioxidee of carbon, nitrogen, etc.) also evaporate from the water once the boiled water has cooled. , there is no more gas in it. If there is no oxygen, the fish will die due to severe lack of oxygen.
Detailed information:
The respiratory organ of fish consists of gills, which have a large number of structures resembling to filaments called gill filaments. The gill filaments are rich in capillaries and oxygen dissolved in water passes through the capillary walls of the gill filaments for gas exchange with the blood.
If you want to raise fish in cooled water, you must first add oxygen to the cold boiled water so that the goldfish placed in it can receive enough oxygen. oxygen to survive. In addition to adding oxygen, some necessary conditions must be met for fish to live better, such as: adding quantitys of essential trace elements, maintaining a moderate temperature, continuous supplementation of oxygen, cleaning of dirt and adding appropriate amounts of nutrients. feed, etc.
