A Preliminary Study of the Marine Biota at Navassa Island, Caribbean Sea

A preliminary study of reef fish and sharks was conducted at Navassa Island in the Caribbean Sea during a 24-h period beginning 9 September 1998. Conducting a study at Navassa Island was of particular interest because exploitation of Navassa Island’s fishery resources has been considered minimal due to its remote location (southwest of the Windward Passage, Caribbean Sea) and lack of human habitation. Reef fish (and associated habitats) were assessed with stationary underwater video cameras at 3 survey sites; sharks were assessed by bottom longlining at 5 survey sites. Fifty-seven reef fish identifications to lowest possible taxon were made from video footage. Longline catches produced 3 shark species and 3 incidental catch species. When results from the 1998 National Marine Fisheries Service (NMFS) project are combined with a previous 1977 NMFS survey of Navassa Island, 27 fish families, 79 fish identifications to lowest possible taxon, 4 invertebrate orders or families, 3 coraline families, and 2 macroalgae phyla are reported.
