Description

Technical Field

[0001] The utility model belongs to the technical field of aquaculture, and in particular relates to a circular fish escape prevention device with an observation window. Background Art

[0002] Most wild fish have a large stress response in the early stage of domestication, and are prone to jumping out of the breeding pond and dying. During the breeding period, the broodstock in the temporary holding pond are in estrus and are more active. They often jump out of the breeding pond, leading to accidental death. In the prior art, in the process of aquaculture, in order to prevent the escape of adult fish in the breeding pond and broodstock in the temporary holding pond, a large fishing net is often used to set up an interception net or an escape prevention net around the breeding pond, and then a heavy object is used to press the edge of the breeding pond to fix the net so that the net is in a taut state. There is no small net with the same diameter as the breeding pond on the market. The interception net or escape prevention net used is often much larger than the breeding pond. The excess nets are piled around the breeding pond, affecting the safety of operation. There is a certain risk of placing heavy objects on the edge of the breeding pond. If the heavy objects fall into the pond, it is easy to hurt the fish in the pond; this temporary escape prevention net is also inconvenient to check the fish in real time; at the same time, the interception net is made of soft material and has poor escape prevention performance. Fish with strong jumping ability still escape. If the escaped fish is not found in time, it will die, and the loss is too great. Utility Model Content
