Are Lionfish Numbers Up or Down?

In talking with others over recent months, and based on my own observations, lionfish population size seemed to be dropping around Abaco.  But much evidence to the contrary this trip.  There was at least 1 lionfish, and as many as 6, on the small reefs we built back in 2009.  And yesterday I checked some of the sites we used in this study.   Here is some video – as many as 15 on small patch reefs.  Parrotfish were the most common prey I found in their stomachs yesterday; for our own stomachs, we went with curry/cumin lionfish.

Craig Layman
My lab’s interdisciplinary pursuits provide for a multi-faceted understanding of environmental change in the coastal realm. We are ecologists, asking questions that span population, community, ecosystem and evolutionary sub-disciplines. We often use a food web based perspective, exploring top-down (e.g., predation) and bottom-up (e.g., nutrient excretion) mechanisms by which animals affect ecosystem processes. All of our efforts are framed within a broader outreach framework, directly integrating science and education, using approaches such as this website.
