A Comparison Of Fish Assemblages Among Five Habitat Types Within A Caribbean Lagoonal System, Ivan Mateo, William J. Tobias
Gulf and Caribbean Research
Fish assemblages associated with patch reefs, rubble, seagrass, algal plain, and sandy habitats types were studied at St. Croix's Southeastern barrier reef lagoon using underwater visual census techniques. Higher species richness and fish density were observed over patch reefs/rubble habitat followed by seagrass, algal plain, and unvegetated sandy habitat types. Thalassoma bifasciatum, Haemulon flavolineatum, and Acanthuras chirurgus were the most common fishes in highly structured habitat types (patch reef, rubble). Halichoeres bivittatus, Sparisoma radians, newly settled grunts (l.e., Haemulon spp.), and juveniles of Ocyurus chrysurus were mainly associated with vegetated habitat types (seagrass, algal beds), while …
