Settlement type artificial fish reef structure

Abstract

The invention provides a settlement type artificial fish reef structure. The settlement type artificial fish reef structure comprises a cement fish reef base plate and damping pieces, wherein the cement fish reef base plate is erected on a supporting assembly, vertically-arranged mounting columns are fixedly mounted on the two sides of the cement fish reef base plate correspondingly, and a first fish sheltering piece and a second fish sheltering piece which are distributed up and down are mounted on the mounting columns; and the first fish sheltering piece and the second fish sheltering piece are the same in specification, and the damping pieces used for reducing swing of the gravity center of the cement fish shelter base plate are mounted on the second fish sheltering piece. According to the settlement type artificial fish reef structure, water flow can flow smoothly, the problem of flow choking in a seabed local water area is solved, a cement block in the fish sheltering piece is provided with criss-cross through holes and through cavities, the fluidity of the whole water flow is extremely good, besides, the shielding performance of the fish reef structure is guaranteed, the gathering effect of juvenile fishes is extremely good, and an adult fish habitat field, a fish spawning field and a juvenile fish protection breeding field are created.

Description

technical field [0001] The invention relates to the technical field of fishery equipment, in particular to a sunken artificial fish reef structure. Background technique [0002] Artificial fish reefs are structures artificially set up in the sea. The purpose is to improve the ecological environment of the sea area, create a good environment for marine organisms to inhabit, and provide places for fish to reproduce, grow, feed and shelter enemies, so as to achieve protection, multiplication and The purpose of increasing catches. At present, the construction of artificial reefs has been extensively carried out at home and abroad, and the restoration of offshore marine habitats and fishing grounds has achieved certain results. However, many artificial reefs in use now have single functions, and artificial reefs are easy to use after a period of use in the sea. The phenomenon of blockage occurs, which is not conducive to the gathering and living of fish schools. [0003] As far...

AI Technical Summary

Problems solved by technology

The concrete frame part has space for adult fish to inhabit. The cylindrical frame on the top of the artificial reef is filled with hollow cubes in a disorderly manner. The reached part has space for juvenile fish, juvenile fish, larvae and bait organisms to live in. The base of the fish reef is circular and concave. A layer of stones with a diameter of about ten centimeters is laid in the tank to form artificial sea cucumber reefs, sea urchin reefs, etc. However, when the concrete structure of the artificial fish reef sinks, it is easy to cause a large-scale impact on the seabed area, resulting in damage to the seabed base. However, the artificial reef with this structure has a single function, and sometimes it is easy to cause the artificial reef to swing to a certain extent when the current on the seabed is large, reducing its stability.
