Hello, first of all, fish can be raised in deep wells, which is beyond doubt, unless it is polluted well water.

Secondly, fish farming in deep wells depends on what fish to raise and how to raise them. It is best to raise fish temporarily in the well water of deep wells, rather than for a long time. And if you keep edible fish, you can keep it for several months, but if you keep goldfish, it is not suitable. The reasons for not keeping goldfish are as follows:

1: temperature difference. 2. Resist. 3. Trace elements, etc.

So to sum up, it is no problem to raise fish temporarily in deep wells, but there are many disadvantages in raising fish for a long time.

Extended data Deep well refers to a well used to obtain deep groundwater, which is usually found in arid areas, such as northwest China, and is mainly used to obtain deep groundwater (that is, water below 20 meters underground).
