At present, the construction of artificial fish reefs is widely carried out at home and abroad to repair the habitats and fisheries of offshore marine organisms, and better economic and social effects are achieved.

The artificial fish reef has various structures and materials according to the specific characteristics of the throwing environment and the expected obtained effect. The artificial fish reef material can be mainly divided into 4 types of over 200 types, such as natural material, waste material, building material and other material. Currently, the reef structure is mainly considered to be in accordance with the characteristics of the marine environment and the sea area to be launched, safety, environmental protection, easy construction, economy and the like.

The traditional artificial fish reef main body is located on a hard rock seabed covered by fine sand in a shallow layer. The artificial fish reef is difficult to build on silt, and after the artificial fish reef is put in, the reef body can sink or be buried under the scouring action of ocean currents on the silt, so that the ecological regulation and control function cannot be normally exerted.

The yellow river mouth is used as the largest river mouth in the north of China, the coastal river mouth has wide silt substrate tidal flat, is influenced by tidal monsoon, land silt runoff and the like, the substrate sediment is loose and has strong fluidity, and the silting thickness shows obvious seasonal change of 'summer storage and winter transportation'. Second, the yellow river mouth has a strong tidal action, the tidal nature is an irregular half-day tide, the tidal flat substrate is exposed temporarily, and the substrate organisms are threatened by sunlight irradiation and water shortage for several hours. Thirdly, in the ice season in winter, the coastal sea ice of the yellow river estuary and the river ice when the river is opened have strong damage effect on the water structure. Fourthly, a plurality of ports and wharfs are arranged along the bank of the yellow river mouth, and structures are arranged inside and outside the tidal flat area to ensure the smoothness of the navigation channel, so that the yellow river mouth is not suitable for putting in large cement reefs. Fifthly, the coastal tidal flat areas at the yellow river mouths belong to ecological national-grade marine special protection areas at the yellow river mouths, and the protection areas have high requirements on environmental protection of materials of external structures.

Oyster reefs in large areas are distributed on the coasts of the yellow river mouths and are marine habitats with high biodiversity. However, due to excessive development, the original oyster reef mountain environment loses the natural property, the amount of mud and sand entering the sea from the river mouth is large, shellfish larvae of oysters and the like which grow subsequently cannot be fixed on the soft muddy sediment substrate to continue to grow to form reefs, shells of the shells are damaged by external power such as tide, waves and the like to be carried, and therefore the supplement capability of various fishery resources such as local shellfish and the like is reduced, the resources are seriously declined, and distribution areas are atrophied. And in the ice season in winter, the sea ice drifting along the coast of the yellow river mouth and the river ice at the time of opening the river have strong damage effect on the water structure. The yellow river mouth is also provided with a plurality of ports and wharfs along the bank, and the smooth navigation channel is ensured by built-in structures inside and outside the tidal flat area. In addition, tidal flat areas along the coasts of the yellow river mouths are planned to be ecological national-grade marine special protection areas of the yellow river mouths, and the protection areas have high requirements on environmental protection of materials of external structures. In order to restore the ecological environment of the yellow river mouth, an ecological artificial fish reef device which is environment-friendly, convenient to move, flexible in arrangement, capable of keeping stable on a sludge substrate, free from silting and burying and in accordance with the characteristics of biological attachment in the region needs to be developed.
