[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] Marine ranching is a fishery model based on the principles of marine ecosystems. In specific sea areas, artificial reefs, stock enhancement, and other measures are used to construct or restore the habitats needed for marine organisms to reproduce, grow, forage, or avoid predators, thereby increasing and conserving fishery resources, improving the marine ecological environment, and achieving sustainable utilization of fishery resources. The integrated development of marine ranching and offshore wind power is a typical combination of modern high-efficiency agriculture and clean energy industry. By utilizing unused sea areas within wind farms for marine aquaculture, both power generation and fish farming can be carried out in the same sea area, achieving the goals of intensive use of the sea and three-dimensional development and efficient utilization of marine space. Currently, the combination of offshore wind power and marine ranching faces the following problems: (1) limited space for aquaculture and operation; (2) poor overall integration structure stability.
