[0002] Aquaculture is an activity in which humans utilize water areas available for aquaculture (including planting), and according to the ecological habits of aquaculture objects and the requirements for water area environmental conditions, apply aquaculture technologies and facilities to engage in the breeding of aquatic economic animals and plants.

[0003] Cage aquaculture is a production method in which a cage made of netting is placed in a certain water area for fish farming. The cages are mostly set in waters such as lakes, rivers, and reservoirs with a certain water flow, fresh water quality, and relatively high dissolved oxygen content. High-density intensive farming can be implemented. Calculated by the bottom area of the cage, the yield per square meter can reach more than a dozen to dozens of kilograms. The main fish species cultured are carp, tilapia, rainbow trout, etc. In China, silver carp, bighead carp, grass carp, and blunt snout bream are also cultured.

[0004] The existing cage devices for aquaculture are usually made up of an installation frame and a fishing net. However, the structural stability of the fishing net is limited, and the fishing net is usually made of a whole piece of fishing net. As a result, when the fishing net is damaged, the entire fishing net structure needs to be replaced, resulting in a relatively high maintenance cost. In addition, it is not convenient to divide the area within a breeding area surrounded by a piece of fishing net, resulting in poor flexibility and applicability of the device.

[0005] In view of this, the present utility model is specifically proposed. Summary of the Utility Model
