Lionfish, an invasive predatory fish from the Indo-Pacific, have been altering the native reef fishes communities on coral reefs throughout the Caribbean for the past decade. In Panama, recreational divers with the Clear This Fish Foundation have been removing lionfish from reefs near Portobelo since 2009.

Our goal is to measure the success of these efforts by scientifically evaluating native fish biomass on reefs cleared of lionfish compared to nearby reefs where the lionfish remain.
