Reef fish populations were found to be dominated by juveniles and small adults with few larger fish. Predatory food fishes were uncommon, and consisted predominantly of graysby, red hind, coneys, yellowtail snapper and mahogany snapper. Some reefs had fairly high numbers of parrotfish, these were generally juveniles and initial phase fish, with few large terminal phase males. The other important herbivorous fishes, the surgeonfishes, also generally occurred as individuals or in very small schools. Large motile invertebrates including lobster and conch were also rare. Invasive lionfish were noted in several locations, but numbers were fairly low (<2/reef) (Fishbase 2014)25.
