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 ARs outside no-take zones, where fish might be subject to enhanced exploitation due to easier catchability Here, we conducted an interdisciplinary study on how ARs impact fish and fishing yields, combining mathematical and sociological approaches. Both approaches confirmed that fishery yields declined when ARs were exploited as if they were open access areas. This situation typically occurs in areas with weak governance, which is common in developing countries. To avoid these adverse effects we recommend to prioritize the onset of a long-term surveillance system against illegal fishing activities, and to adapt design and location of the ARs based on both and local and academic knowledge, before the deployment of ARs. |
