Coastal Blue Crab

The blue crab (Callinectes sapidus) is one of the most important commercial species in the United States, especially in the Chesapeake Bay region on the Mid-Atlantic coast. Its populations are affected by local water quality, overfishing, reproduction dynamics and bycatch amounts, and efforts to protect the region and crab species have been ongoing. Parasites can also affect the commercial viability of the crabs
