Abstract:

The feasibility of using man-made reefs to concentrate populations of food fishes (Lutjanidae and Haemulidae) was investigated in Bahamian waters. Fourteen reef units, constructed of PVC pipe and concrete blocks, were installed in seagrass beds and sand bottom habitats at depths of 4–5 m in July of 1982. The units were highly successful in attracting the target species, and appear to offer a promising method of substantially increasing the readily available protein supply for islanders throughout the Caribbean at a relatively low cost. Comparisons of the fish communities associated with natural patch reefs and man-made reefs in both habitats suggest that reef structure is subordinate to source of recruitment as a determinant of reef fish community structure.
