This field experiment was conducted on coral patch reefs to test for the effect of lionfish presence on native fish abundance both on main reefs where lionfish resided and in habitats surrounding the main reefs (satellite coral heads, open areas, and standardized habitat units [SHUs]). The experiment used 16 main reefs which were manipulated so that 8 reefs had few lionfish present (low lionfish treatment) and 8 had lionfish present at naturally-observed densities (high lionfish treatment). Complete censuses of the native prey fish populations on each reef and in the surrounding habitats were conducted weekly for 7 weeks during the summer recruitment season.
