dc.description.abstractBlue crabs, Callinectes sapidus, caught from salt marsh, brackish marsh, beach, and nonvegetated bay habitats of Galveston Island, Texas, were examined for deeding behavior and diet. Six types of feeding behavior were observed in the field, which allowed blue crabs to produce a variety of food items (10 categories). Of 409 stomachs with food, 42% contained mulluscs, 29% with vascular plants, 26% fish, 25% benthic algae, and 21% crustacean exoskeleton. Diet appeared to a reflection of both size (large crabs carapace width >60 mm utilized fish, mollusks, fish, and crustaceans more frequently) and food availibility. Based on observations of feeding behavior and stomach analysis, the blue crab occupies detitivore, omnivore, and primary carnivore trophic levels in this coastal ecosystem.en_US
