ABSTRACT: Fish and decapod community structure and catch per unit effort (CPUE) were assessed within a mangrove previously impacted by a hurricane and an adjacent seagrass bed in St. John, United States Virgin Islands. Diel sampling utilizing minnow traps showed significantly greater total fish CPUE in the seagrass habitat with few individuals using the mangrove regardless of the time of day. Decapods showed no difference in CPUE and were equally distributed between mangrove and seagrass habitats. When individual species were analyzed, Haemulon flavolineatum, H. sciurus, Calcinus elegans and Panulirus argus had significantly higher CPUEs in seagrass beds compared to the ... <25%), but strong dissimilarities among all sampling combinations (>
