Abstract

The invasive lionfish (Pterois volitans), native to the Indo-Pacific region is currently established along the North, South and Central American coasts, the Gulf of Mexico and the Caribbean islands. A gluttonous generalist diet coupled with high growth, reproductive and feeding rates and the absence of natural enemies bequeaths lionfish with vast potential to wreak havoc and decimate native ecosystems. Throughout the invaded region, attempts have been made to quell the lionfish invasion and mitigate further impacts. Bonaire, an island within the Southern Dutch Caribbean is one island that can boast of a successful lionfish management strategy. Since the confirmation of the first lionfish in October 2009, Bonaire utilised the early and rapid response technique in managing this invasive species. The easy access shore diving sites along with the availability of dedicated volunteer divers and a research institute has allowed Bonaire to successfully manage and monitor their lionfish population. Since 2009, > 6000 specimens have been submitted to CIEE Research Station Bonaire so that their general, feeding and reproductive ecology could be assessed. This research was extended to neighbouring islands; Klein Bonaire and Curacao in 2012 so that comparisons could be made. This research has achieved great insight into lionfish feeding ecology and preferences and what their perfect prey item may be and the consequent impacts. Furthermore, the research highlights how instrumental volunteers are to successful management of invasive species.
