Intraspecific interference among foraging blue crabs Callinectes sapidus: interactive effects of predator density and prey patch distribution Mary E. Clark 1, *, Thomas G. Wolcott 1 , Donna L. Wolcott 1 , Anson H. Hines 2 Callinectes sapidus (from the Greek calli-= "beautiful", nectes = "swimmer", and Latin sapidus = "savory"), the Blue Crab, Atlantic Blue Crab, or regionally as the Chesapeake blue crab, is a species of crab native to the waters of the western Atlantic Ocean and the Gulf of Mexico, and introduced internationally. Blue crabs Callinectes sapidus are voracious predators in Chesapeake Bay and other estuarine habitats. 33 Blue Crab, Callinectes sapidus (Rathbun, 1896) Life History In the western Atlantic, Blue Crabs are distributed from Nova Scotia south to northern Argentina, including Bermuda and the Antilles. The blue crab, Callinectes sapidus is an abundant predator that is widely distributed throughout the estuarine ecosystems of the eastern United States and the Gulf of Mexico. Biol. Callinectes similis is an omnivore and their diet consists of four main prey; fish, bivalves, crabs and gastropods (Hsueh et al., 1992). Su cuerpo está cubierto de un exoesqueleto color verde oscuro.En los machos, las patas tienen un color gris-azulado, y esta característica es la que les ha dado el nombre común de jaiba azul.. 1984. Taylor DL(1), Calabrese NM(2). Differences in Prey Capture Behavior in Populations of Blue Crab ( Callinectes sapidus Rathbun) from Contaminated and Clean Estuaries in New Jersey HABITAT COMPLEXITY AND PREDATION BY CALLINECTES SAPIDUS 1 07 1 complexity of the habitat, (3) the wide geographic distribution of some predators in both temperate and tropical regions, (4) the mobility of prey and their Journal Animal Ecology … Blue crabs (Callinectes sapidus) are major predators of juvenile oysters (Crassostrea virginica) in Chesapeake Bay, yet little information exists on the foraging behavior and predator–prey dynamics for this predator-prey system. Recently, blue crab (Callinectes sapidus) landings have dramatically increased in the New York region to levels not observed since the 1870s , . Effects of hypoxia on predator-prey dynamics of the blue crab Callinectes sapidus and the Baltic clam Macoma balthica in Chesapeake Bay R. D. Seitz1,*, L. S. Marshall Jr2, A. H. Hines3, K. L.

Mercury content of blue crabs (Callinectes sapidus) from Southern New England coastal habitats: Contamination in an emergent fishery and risks to human consumersTotal mercury (Hg; ppm dry weight) was measured in blue crabs, Callinectes sapidus, collected from Narraganset Bay and adjacent coastal lagoons and tidal rivers (Rhode Island/Massachusetts, USA) from May to August 2006–2016. They This study examined predation by the blue crab, Callinectes sapidus Rathbun, within intertidal Spartina alterniflora (Loisel) marshes of Dauphin Island, Alabama.R.T. Prey preferences of blue crabs Callinectes sapidus feeding on three bivalve species Elizabeth L. Ebersole*, Victor S. Kennedy* University of Maryland System, Horn Point Environmental Laboratory, PO Box 775, Cambridge Significant differences existed between prey types consumed by red drum during fall and spring seasons, which were likely a Caught at Long Point Dock, North Core Banks, North Carolina, USA. Callinectes sapidus has a broad tolerance of temperature and salinity, but may avoid oxygen depletion by swimming away (Hines, 2003). linectes sapidus prey on cultchless oysters up to 40 mm in shell length (Krantz and Chamberlin 1978).

In marine systems, a pattern of preference for small-sized molluscan prey is widespread among crustacean Blue crab landings have been shown to track abundance [17] and so it is likely the increase in harvest reflects population trends. To define general principles of predator-prey dynamics in an estuarine subtidal environment, we manipulated predator density (the blue crab, Callinectes sapidus) and prey (the clam, Macoma balthica) patch distribution in large field 1.
