Composite type artificial algal reef

Abstract

The invention discloses a composite type artificial algal reef comprising a mature algal reef and a seedling reef. The mature algal reef comprises a solid base. The upper surface of the solid base is embedded with a metal frame, wherein the shape of the metal frame is identical to that of the upper surface of the solid base and the size of the metal frame is identical to that of the upper surface of the solid base. A conch net bag is arranged in the metal frame. The center of the upper surface is embedded with a metal stand column. A steel ring is welded to the upper end of the stand column. A plurality of seedling ropes are fixed between the metal frame and the steel ring. The seedling reef is fixed to the side face of the solid base of the mature algal reef, and algal seedlings are attached to the seedling reef. By the adoption of the composite type artificial algal reef, the attaching effect of alga is guaranteed, the repair period of an algae field is shortened, the success rate of repair and reconstruction of the algae field is improved, the adhesive rate of the seedlings is increased, and the seedling reef is firm, durable, small in size, light, and convenient to carry; the net bag made of waste conches is placed in the metal frame, and a biophile reef can be composed through diffusion and attachment of spores of fronds on the seedling ropes; resource utilization of the waste conches is achieved, and composite type artificial algal reef has the advantages of being economical and easy and convenient to use.

Description

technical field [0001] The invention relates to a composite artificial algae reef combining algae transplantation and seedling attachment. Background technique [0002] Algae farms are an important part of marine ecosystems, which can provide habitats, spawning, brooding, baiting and avoiding enemies for a variety of marine organisms. It plays an important ecological role in improving the carbon sequestration capacity of the ocean. However, since the 1980s, my country's coastal natural algae farms have been severely degraded, mainly due to land reclamation, land-based pollution, and unreasonable fishery production. Therefore, the restoration and reconstruction of the algae farm is urgent. The placement of artificial algae reefs is an important measure for the restoration and reconstruction of algae farms. In recent years, a series of related researches have been carried out on the materials, shapes, and functions of reefs. [0003] Currently commonly used algae reef mater...

AI Technical Summary

Problems solved by technology

Due to the low affinity between concrete and seaweed seedlings, the attachment rate of algal reef seedlings with concrete surface is low; in order to increase the attachment area of ​​spores, most algal reefs are designed into a large cylindrical or box shape, which is not easy to carry , and most of the algae reefs are still in the form of single seedling attachment or algae transplantation, and the efficiency and success rate of repairing and rebuilding the algae field are low
