Food of Paralichthys dentatus and P. lethostigma (Pisces: Bothidae) in North Carolina estuaries

The diets of the spatially segregated summer flounder, Paralichthys dentatus, and southern flounder, P. lethostigma, in Pamlico Sound, North Carolina, were composed of crustaceans and fishes. Young flounders fed mainly on mysids and fishes throughout the year, but the ratios of these items differed between species. Feeding was minimal during winter, but summer flounder from near-inlet stations had a high frequency of stomachs with food. Older summer flounder fed equally on shrimp and fishes, while southern flounder fed almost solely on fishes. This difference was probably related to food availability.
