The feeding ecology of the black sea bass, Centropristis striata, associated with artificial reefs shows seasonal and size-related changes. Monthly collections totaling 520 black sea bass taken from an artificial reef near the Chesapeake Light Tower, Virginia, between August 1975 and May 1976, were analyzed for food habits as revealed by number, volume, frequency of occurrence and a modified Index of Relative Importance.

The black sea bass feeds on the artificial reef as well as the adjacent areas. When food was abundant on the reef, food items from the reef and the surrounding area were consumed. Upon depletion of the food resource on the reef, the black sea bass resorted to feeding primarily from the areas adjacent to the artificial reef. The four overall predominant foods were Ensis directus (IRI'=910), Pagurus spp. (IRI'=7299), Cancer irroratus (IRI'=601) and Mytilus edulis (IRI'=332). The feeding ecology of the black sea bass on the artificial reef suggests that they are attracted to the reef primarily because of the shelter that the reef affords.
