The livelihood of 200,000 inhabitants is threatened by declining fishery yields and degraded marine habitats in the Bay of Ranobe, Southwest Madagascar. Reef Doctor proposes to install artificial reefs to provide alternative habitats for marine lives, bolster local fishing yields, and reduce stress on over fished reefs. This project will reveal the effects of artificial reef establishment on ecological communities and fishery output. The potential success of this pioneering effort, indicated by an increase in fish and invertebrate abundance and catch, will offer a low-cost, practical, and reproducible solution to other coastal environments in the region where marine resources are over-exploited.
