[01] The invention relates to an artificial marine habitat, belonging to the technical field of marine aquaculture infrastructure. More specifically, it is an artificial marine habitat with multi-trophic levels, providing habitats for breeding, feeding, growth and the like for sea treasures, reef-loving fish and algae.
[02] Overfishing, water pollution and global climate change have brought great pressure on marine fishery resources and ecological environment. In order to improve the declining fishery resources and restore the ecological environment of coastal waters, the mode of fishery industry in China is changing from traditional fishing and breeding to resource conservation. As an important measure to conserve resources and repair the environment, the construction of artificial marine habitats has become one of the important directions in the development of marine fisheries in China. At present, artificial marine habitats have been built in all coastal provinces of China, and the marine habitats are mainly rock reefs and concrete reefs. Although these have played a certain role in the improvement of marine resources, there are some problems such as simple reef structure and single ecological function in reef area. Taking the construction of artificial marine habitats in the Yellow Sea and Bohai Sea as an example, which is mainly aimed at proliferating choice rare sea food such as Stichopusjaponicus.In order to save costs and pursue economic value, the reefs are basically made of natural stone and simple square and round concrete. It only pays attention to the habitat needs of the breeding objects, but not fully considers the biological community structure and functional group configuration of the artificial reef ecosystem, resulting in the death of proliferating species, simple food web structure and low level of biodiversity caused by the lack of biological carrying capacity.
