Advisor. Garber, Nikola Marie Though these traps are successful in capturing larger decapods that cannot escape through the meshing around the trap, they are not suitable for other smaller species (adults or juveniles that are generally <5cm carapace width) that can escape. Habitat. Callinectes sapidus, the blue crab, is a bottom-dweller found in a variety of habitats ranging from the saltiest water of the gulf to almost fresh water of the back bays. Especially common in estuaries, this species ranges into fresh water, and may be found offshore. Fish such as mullet , flounder (Paralichthys lethostigma), shad (Alosa sapidissima), and blue crabs (Callinectes sapidus) migrate ... zooplankton and phytoplankton take that role in the estuarine habitat. Population ecology of the blue crab, Callinectes sapidus Rathbun, in a subtropical estuary: population structure, aspects of reproduction, and habitat partitioning [1994] Steele, P. Bert, T.M. The overall objective of this research, conducted by Paul Jivoff, Ph.D. of Rider University, was to examine the effect of bulkheading on marine and estuarine habitats, the diversity of species and the relative abundance of individuals, particularly the blue crab, Callinectes sapidus. Stocks of estuarine migrant species can be challenging to assess due to a relative lack of abundance data in offshore areas and complex interactions between spawning behavior and estuarine geomorphology.

Mollusks gather at the St. Johns estuary in large numbers, feeding on the bottom of the river and ocean floors. Predation in estuarine systems is an important source of mortality for benthic organisms. Florida Marine Research Institute (USA) [Corporate Author] 2020-04-23 Author.
Their scientific name, Callinectes sapidus, means "savory beautiful swimmer." The blue crab, Callinectes sapidus Rathbun (1896), is a commercially important brachyuran crab species throughout the Atlantic and Gulf Coasts of the United States, with 2007 landings totaling over 62,000 metric tons ().Catch data indicate that large-scale fluctuations in annual abundance are characteristic of blue crab populations, yet the underlying causes are unknown. Major Professor: Richard W. Heard (Research Director: Chet F. Rakocinski). Blue crabs Callinectes sapidus are voracious predators in Chesapeake Bay and other estuarine habitats. While blue crabs do … Prey selection by juvenile crabs, Callinectes sapidus between two micrograzing gastropods, Astyris lunata and Bittiolum varium, within estuarine seagrass habitat. The blue crab (Callinectes sapidus) is known for its color and delicious flavor.The crab's scientific name means "savory beautiful swimmer." Date. Thesis, Marine Science.
