Transition of artificial reefs (ARs) research and its prospects

This literature review encompasses more than one-hundred and sixty worldwide studies on artificial reefs (ARs) in terms of their design, application, performance and management. Over the past three decades, research on ARs has increased remarkably, suggesting an increase in social and economic aspects of ARs. The scope of AR research has largely expanded from early AR design and deployment to improve fisheries to various additional purposes. In particular, recent research on ARs has had a tendency to focus on variations in the community structure or composition of ARs, suggesting that the purpose of AR research has shifted from improving fisheries as a resource to rehabilitation of marine ecosystems. Most countries are expected to make active use of AR functions, even if the objective of deployment might be different for each case. Consequently, AR research will most likely expand and evolve to span multiple purposes in the future.
