The blue crab is a highly sought-after shellfish. Molting begins when a thin line appears down their backs. | See temporary closures and business changes, Texas Farm and Ranch Land Conservation Program. habitat was defined as a large, continuous, dense bed that could potentially harbor natural predators, including blue crabs. causes algal blooms. Its life history involves a complex cycle of planktonic, nektonic, and benthic stages which occur throughout the estuarine-nearshore marine environment in a variety of habitats. The blue crab has two, stalked, compound eyes, Distributional and experimental evidence suggest that blue crab (Callinectes sapidus) megalopae may preferentially settle into vegetated habitats. Callinectes sapidus (Blue Crab) Order: Decapoda (Shrimps, Lobsters and Crabs) ... HABITAT AND ACTIVITY. Blue crabs (Callinectes sapidus) are the second highest valued fishery in Georgia yet little is known about their essential habitat requirements within either subtidal or Habitat Occupy a range of estuarine habitats as well as coastal bays, sounds and nearshore waters; often in association with submerged vegetation or oyster reefs. 2006), adults are bottom dwellers found from nearshore marshes down to depths up to 40 m/130 ft. Bay mainly, shallow Gulf, prefers muddy and sandy bottoms. C. sapidus is widespread in a variety of habitats ranging from freshwater to saltwater areas where their distribution is based on sex, age and season. Like insects, blue crabs have stalked compound eyes and can see in almost every direction at once. (2014) estimated the potential value of additional habitat created by oyster aquaculture to increase commercial and recreational fisheries by approximately $925 and $632 yr-1 ha-1 respectively.

Most research on the early life history oft he blue crab, Callinectes sapidus, has been conducted in large partially stratified estuaries such as the Chesapeake Bay.

Other Common Names. ABSTRACT We examined how post-larval blue crab (Callinectes sapidus) dispersal occurs within Pamlico Sound, NC, USA, a predominantly wind-driven system. Adult Callinectes similis occur in the oceanic littoral zone in salinities above 15‰ at a depth of 100 meters along the eastern seaboard from Delaware Bay to Key West, Florida and southern coasts of the United States, to the Yucatan, Colombia and northern Jamaica (Williams 1984, Piller et al.
