Abstract

Introduced in the 1980s, Indo-Pacific Lionfish (Pterois volitans and P. miles) are the first established marine invasive fish species off the Atlantic Coast, Caribbean, and Gulf of Mexico. In 2010, lionfish were ranked among the top fifteen greatest threats to global biodiversity, capable of removing over 90% of native reef fishes. Once established, an invasive marine species is nearly impossible to eradicate; however, we can aim to suppress the population through organized control efforts. Here we present results from preliminary pilot-surveys from stakeholder groups influential in developing a lionfish fishery in Aruba. In 2014, individuals (n = 117) were surveyed about their awareness of lionfish and willingness to utilize it as a food resource. In addition, 734 lionfish were removed to obtain length-weight relationships – the first to be reported for the island. Our preliminary approach uses results from pilot-surveys to determine the interest and feasibility of creating a lionfish fishery, while we use catch-per-unit-effort estimates to determine if commercial divers can contribute to a viable seafood market. Fifty-six percent of government officials viewed lionfish positively providing they can be utilized as a food resource. Eighty percent of individuals surveyed (locals and tourists) were willing to eat lionfish, with 61% of them never having tried it. Sixty-two percent of fishermen were willing to participate in a lionfish fishery. Preliminary survey results suggest Aruba is willing to support dedicated lionfish removal teams. We acknowledge that creating a lionfish fishery is beyond traditional fisheries management goals; however, employing a long-term, ecologically and economically sustainable removal effort will be necessary to effectively combat lionfish in their invaded region
