Sea urchin eating-proof artificial algal reef

Abstract

The invention relates to an artificial algal reef which can avoid being damaged by sea urchin. The invention is characterized in that; the reef is formed by several accumulated reef discs into cylinder or square structure, while the section of circumference is in saw shape, and the upper part of reed is concave-convex face. The invention has the advantages in the prevention of sea urchin, to protect the algal, with simple structure, low cost and easy production, while it can add glass slag on the face to apply the growth of algal.

Description

technical field [0001] The invention relates to an artificial algae reef, in particular to an artificial algae reef capable of resisting sea urchins from preying on the algae growing on the reef body. Background technique [0002] At present, due to the destruction of bottom trawls, the development of coastal aquaculture, the discharge of a large amount of land-based pollutants, and the unreasonable development and utilization of the ocean, seabed vegetation has been destroyed, and desertification is becoming more and more serious, which will in turn cause economic fish and shrimp. Spawning grounds and baiting grounds have disappeared, and fishery resources are difficult to sustainably develop. Therefore, the artificial restoration of seabed vegetation is imminent. And the important means of recovering seabed vegetation is exactly in seabed afforestation, namely the artificial construction algae field. The algae field can be used as a purification field for water areas, pr...

Problems solved by technology

[0004] After the algal reef is put into the sea, various algae will slowly grow on the reef, but due to the ingestion of algae by various benthic organisms, especially sea urchins, the growth of algae on the reef is greatly affected, thus affecting the artificial algae farm. If the construction effect is serious, the algae on the reef will die and disappear, and the construction of the artificial algae field will fail, thus failing to achieve the purpose of restoring the water environment and transforming the seabed habitat

At present, there is no very effective solution to this problem. Japan has used nets to cover the outside of the algae field to prevent sea urchins from climbing up to the reef to feed on algae. Although it has achieved certain results, the project is relatively large and consumes manpower, material and financial resources. , so how to design reefs to build artificial algae fields to prevent sea urchins, shellfish and other organisms from ingesting algae has become an important issue for the success of artificial algae field construction
