Highlight: Lionfish Invasion!

Mark Albins conducting underwater Lionfish researchInvasion of Atlantic Coral Reefs by Pacific Lionfish

In 2007, our long-term research on the ecology of coral-reef fishes in the Bahamas was interrupted by a population explosion of invasive Pacific lionfish. Protected by cryptic color and form, as well as by venomous spines, these voracious predators of small fish and other reef animals had been introduced to the Atlantic, probably as a result of aquarium releases in the early 1990s.

Funded by the National Science Foundation, my lab is actively studying this invasion, focusing mostly on the ecological effects of lionfish on Atlantic coral-reefs ecosystems.  Our first field experiment, conducted by Ph.D. student Mark Albins (left), demonstrated that a single lionfish can reduce recruitment of native fishes on a small coral patch reef by about 80% is just 5 weeks (Albins & Hixon 2008). To the extent that such effects are typical, this could very well become the most disastrous marine invasion in history (Albins & Hixon 2013).

An important recent finding is that raw lionfish (and scorpionfishes in general) may give false positive tests for ciguatera (a kind of fish poisoning) (Wilcox & Hixon 2014).  If so, then efforts to control the invasion by eating lionfish via community derbies and targeted fisheries may be unnecessarily impeded.  The easy solution is to test for ciguatera after the fish is cooked, which prevents false positive tests.
