520 3 a| Trophic and temporal partitioning studies were conducted on Centropristis striata, Pareques umbrosus, Stenotomus aculeatus, and Haemulon aurolineatum inhabiting a near-shore rock outcrop in Onslow Bay, N. C. C. striata was found to be an opportunistic daytime feeder with Crustacea comprising the bulk of the diet followed in order of abundance by fish, echinoderms, tunicates, molluscs, and polychaetes. Larger individuals preferred crabs, fish, and tunicates while shrimp, crabs, and amphipods were more abundant in the smaller fish. Stenotomus aculeatus also showed an opportunistic daylight feeding regimen with a fairly equal utilization of echinoderms, polychaetes, and Crustacea as food items. Molluscs and tunicates made up the remainder of the diet. Both S. aculeatus and C. striata showed some evidence of a crepuscular habit. Pareques umbrosus was a fairly selective nocturnal feeder with Crustacea making up the majority of the diet while feeding to a lesser extent on polychaetes, molluscs, and echinoderms. Haemulon aurolineatum also demonstrated nocturnal feeding and although the overall diet study for this species was inconclusive, Crustacea appear to be a main component of this diet. Centropristis striata and Pareques umbrosus seem to minimize intraspecific trophic competition through changes in diet with changes in predator size. Direct interspecific trophic and temporal competition among the four species is lessened by adopting different activity periods and to some extent feeding habits.;

Summary	Trophic and temporal partitioning studies were conducted on Centropristis striata, Pareques umbrosus, Stenotomus aculeatus, and Haemulon aurolineatum inhabiting a near-shore rock outcrop in Onslow Bay, N. C. C. striata was found to be an opportunistic daytime feeder with Crustacea comprising the bulk of the diet followed in order of abundance by fish, echinoderms, tunicates, molluscs, and polychaetes. Larger individuals preferred crabs, fish, and tunicates while shrimp, crabs, and amphipods were more abundant in the smaller fish. Stenotomus aculeatus also showed an opportunistic daylight feeding regimen with a fairly equal utilization of echinoderms, polychaetes, and Crustacea as food items. Molluscs and tunicates made up the remainder of the diet. Both S. aculeatus and C. striata showed some evidence of a crepuscular habit. Pareques umbrosus was a fairly selective nocturnal feeder with Crustacea making up the majority of the diet while feeding to a lesser extent on polychaetes, molluscs, and echinoderms. Haemulon aurolineatum also demonstrated nocturnal feeding and although the overall diet study for this species was inconclusive, Crustacea appear to be a main component of this diet. Centropristis striata and Pareques umbrosus seem to minimize intraspecific trophic competition through changes in diet with changes in predator size.
