| Concrete coastal infrastructures often lack structural complexity, preventing a wide range of organisms from inhabiting them, which leads to the loss of biodiversity in coastal waters surrounded by such grey infrastructures. For sustainable exploitation of coastal water, amelioration of biodiversity on existing grey infrastructures is essential. In this study, we deployed artificial seaweed (AS), imitating a structure of a natural macroalgae, on a sea wall of a fishing port, and investigated its function connected to the enhancement of biodiversity. |
