Successful artificial reefs depend on getting the context right due to complex socio-bio-economic interactions

Abstract Artificial reefs (ARs) are one of the most popular means of supporting marine ecosystem conservation and coastal fisheries, particularly in developing countries. However, ARs generate complex socio-bio-economic interactions that require careful evaluation. This is particularly the case for...
