Description

Technical Field

[0001] The utility model relates to the technical field of fish breeding, in particular to a water changing device for fish breeding. Background Art

[0002] There are many ways to raise fish, such as pond farming and cage farming. The difference between the two farming methods is that one is artificial water source, and the other is to use natural lakes for farming. The latter natural water source has the ability to purify itself, while when the former is raised, the water source cannot be processed in time because the fish feces and uneaten feed in the water source cannot be processed in time, and they deteriorate and dissolve in the water source, affecting the health of the fish, so it needs to be replaced regularly. When replacing the water source, most of the methods are to replace the water in the breeding pond with clean water sources, and the fish feces and uneaten feed will adhere to the inner wall of the breeding pond after a long time. Simply changing the water cannot completely purify the breeding pond, which increases the probability of fish getting sick to a certain extent. Utility Model Content
