Description

Technical Field

[0001] The utility model relates to the technical field of wuzi cultivation pools, in particular to a drainage auxiliary device used in wuzi cultivation pools. Background Art

[0002] In the process of fish seed cultivation, using ponds to cultivate water flowers into blackfish or summer flowers for sale is an important production method for many breeding practitioners. When the fry are first put into the pond, the water level of the pond is maintained at 50-60cm. After that, new water needs to be added to the pond every 3-5 days to increase the activity space of the fish. However, the continuously rising pond water level makes it difficult to catch blackfish, especially in ponds with high stocking density and long cultivation cycle. Because blackfish are small, tender and weak, their scales have not all grown out, and the fish body is relatively tender, they are easy to stick to the mesh when draining before being caught, which is not only inconvenient to operate, but also easy to cause death. In order to solve this problem, a drainage auxiliary device for blackfish breeding ponds is proposed. Utility Model Content
