Description

Technical Field

[0001] The present invention relates to the technical field of artificial fish reefs, and more specifically, to a combined artificial fish reef. Background Art

[0002] Artificial reefs are structures artificially set up in the sea. Their purpose is to improve the ecological environment of the sea area, create a good environment for marine life to live, provide fish with a place to reproduce, grow, forage and shelter from enemies, so as to achieve the purpose of protection, proliferation and increase of fish catch. However, existing artificial reefs have the following shortcomings: artificial reefs are large in size. After being placed on the seabed, the artificial reefs have less oxygen inside the seabed and are easily affected by the flow rate on the seabed, resulting in a shorter stay time of fish after entering the artificial reefs, reducing the effect of fish reproduction inside the artificial reefs. At the same time, large carnivorous fish will also enter the large artificial reefs to attack the fish inside the artificial reefs and the spawning of reproduction, reducing the shelter effect of artificial reefs on fish.
