Background

In the process of marine fish aquaculture, artificial reefs are required to provide sheltering or breeding sites for fish populations. As is well known, artificial fish reefs are artificial facilities for improving the ecological environment of sea areas, and building fisheries and breeding farms. At present, the artificial fish reefs put into the marine ranching in China are almost all prepared from common reinforced concrete, and the artificial fish reefs are often unsatisfactory in durability of a fish reef structure due to concrete cracking and early corrosion and expansion of reinforcing steel bars in a seawater corrosion environment. Most of the existing thrown artificial fish reefs are reinforced concrete hollow frames with the shapes of cubes, cuboids, triangular prisms, pyramid tables and the like, and the fish reefs mostly have sharp chamfers, so that the flow resistance of the fish reefs at the sea bottom is large, and the anti-overturning property (when the fish reefs are thrown on a hard sand substrate) and the flow field effect are not ideal.

In addition, the size of the existing artificial reef or the size of the thrown reef is determined according to the scale of the culture or the scale of the fishing ground. The existing fish reef is of an integral structure, has the characteristics of large volume and heavy weight, and is not beneficial to throwing.
