Description

Technical Field

[0001] The invention belongs to the technical field of artificial fish reefs, and in particular relates to a corrosion-resistant assembled artificial fish reef and an assembly method thereof. Background Art

[0002] Artificial reefs are structures set up in the sea by humans. Their purpose is to improve the ecological environment of the sea area and create a good environment for marine life to live. Its main functions include: 1) Providing a place for reproduction, growth, feeding and shelter from enemies: artificial reefs can provide a place for reproduction, growth, feeding and shelter from enemies for fish and other marine life, which is conducive to the survival and reproduction of fish and other organisms. 2) Forming an upwelling effect: artificial reefs can make the ocean current move upward, forming an upwelling effect. This process can bring nutrients from the seabed to the surface, promote the large reproduction of plankton, and provide sufficient bait for aquatic organisms such as fish and shrimp. 3) Producing eddy currents: eddies can be generated in irregular terrains such as islands, reefs and capes. Terrain eddies of various sizes can cause the upper and lower water layers to mix, enriching dissolved oxygen and bait, and become a good feeding place for fish and shrimp. In addition, the lateral line of fish is sensitive to changes in low-frequency wave pressure, which is also a major factor in fish gathering. 4) Increasing fishery resources: artificial reefs can attract a variety of fish to live and live, which is conducive to artificial fishing, thereby increasing fishery resources. Artificial reefs play an important role in improving the ecological environment of the sea, providing habitats for marine organisms, and increasing fishery resources.

[0003] Traditional artificial reefs have been found to have shortcomings during use. First, their production cost is high, which is not conducive to mass assembly production. When they are partially damaged, they are not conducive to rapid replacement and often need to be replaced as a whole, resulting in high maintenance costs in the later stage. Second, they cannot be assembled into structures of different structures according to needs, and cannot be folded and stacked during transportation, resulting in low transportation efficiency. Third, their corrosion resistance is poor and their service life is not ideal. Therefore, it is necessary to optimize and improve the traditional artificial reef structure. Summary of the invention
