There is growing concern that lionfish will affect the structure and function of invaded marine ecosystems. REEF Director of Special Projects, Lad Akins, is a co-author on a recently published paper evaluating these effects. The study was published in the scientific journal, PLoS ONE. Lead author, Stephanie Green, from Simon Fraser University (SFU), along with Akins and other co-authors Aleks Maljković (SFU), and Isabelle Côté (SFU), documented a dramatic 65% decline in 42 species of reef fish eaten by lionfish over a two year period. The study, conducted off New Providence Island in the Bahamas, used data collected during REEF's volunteer lionfish projects to track the explosion of the lionfish population over time, and reveals that lionfish biomass increased from 23% to nearly 40% of the predator biomass on the study sites between 2008 and 2010. This study represents the first documented direct impact of lionfish predation on native reef fishes and highlights the importance of control programs to minimize impacts.
