Visual surveys conducted in shallow-water (<10 m depth) reef habitats were used to compare juvenile epinepheline grouper density, size distribution, and diversity in the Exuma Cays Land and Sea Park (ECLSP), Bahamas and in the northern region of the Florida Keys National Marine Sanctuary (FKNMS). The community of juvenile groupers in an area closed to fishing (ECLSP) and in an area with extensive fisheries exploitation (FKNMS) were contrasted for specific reef habitats. Across habitats, the mean density of groupers was three times higher in the ECLSP compared to the FKNMS. Sites in the FKNMS had a significantly lower grouper density. While the ECLSP site had a higher overall percent frequency of groupers in the larger size classes, there were no significant differences in the length-frequency distributions between the two areas. The composition of species observed in each area was remarkably different and was attributed to differences in habitat requirements among species. At the FKNMS sites, graysby Epinephelus cruentatus, red hind E. guttatus, red grouper E. morio and black grouper Mycteroperca bonaci comprised the majority of individuals observed. At the ECLSP sites, Nassau grouper E. striatus and coney E. fulvus were dominant. -from Authors
