Description
Summary:Goldman, S. F. and Sedberry, G. R. 2011. Feeding habits of some demersal fish on the Charleston Bump off the southeastern United States. - ICES Journal of Marine Science, 68: 390-398. The feeding habits of several demersal fish on the upper continental slope were investigated to determine the trophic relationships of these ecologically dominant and commercially important species, and to determine food sources for slope fish off the southeastern United States. Stomach contents were examined from 534 fish, including wreckfish (Polyprion americanus), barrelfish (Hyperoglyphe perciformis), and red bream (Beryx decadactylus). Fish fed on 46 prey taxa, and there were dietary differences among predators. Wreckfish predominantly consumed teleost fish and squid; barrelfish had a diet dominated by pelagic tunicates and some mesopelagic fish and squid; red bream consumed mainly fish, squid, and crustaceans. Seasonal shifts in diet were observed in all three species. Many of the prey items encountered were vertically migrating organisms, which are a critical link between surface waters and the slope ecosystem.
