Multi-nutrition-level artificial fish reef

Abstract

The invention provides a multi-nutrition-level artificial fish reef which comprises an artificial fish reef body and is characterized in that the artificial fish reef body is divided into a sea treasure proliferation layer, a fish protection layer and an algae attachment layer from bottom to top. The sea treasure proliferation layer is a solid body of a quadrangular pyramid trustum, the bottom surface of the quadrangular pyramid trustum is square, and a plurality of vertical through holes are uniformly distributed in the quadrangular pyramid trustum. The fish protection layer is a tetragonal transparent structure, the algae attachment layer is a multilayer grid platform, the fish protection layer is fixed to the sea treasure proliferation layer, and the algae attachment layer is fixed to the fish protection layer. The exchange of nutrient substances in the upper and lower water bodies can be promoted, suitable habitats are provided for algae, reef-loving fishes, sea treasures and attached organisms, and the biodiversity level and the community structure stability of the artificial fish reef ecosystem are improved. The problem is solved that an existing artificial fish reef is single in function, simple in food net structure, low in diversity level of biological communities in reef areas and the like.

Description

technical field [0001] The invention relates to an artificial fish reef, which belongs to the technical field of seawater fishery breeding infrastructure, and specifically relates to a multi-trophic artificial reef that provides breeding, baiting, and growth habitats for sea treasures, reef-loving fish, and algae. fish reef. Background technique [0002] Overfishing, water pollution, and global climate change have brought enormous pressure on marine fishery resources and the ecological environment. In order to improve the declining fishery resources and restore the ecological environment in coastal waters, my country's fishery industry is changing from traditional fishing and breeding to resource conservation. . As an important measure to conserve resources and restore the environment, the construction of artificial reefs has become one of the important directions for the development of marine fisheries in my country. At present, all coastal provinces in my country have car...
