The blue crab Callinectes sapidus has played a central role in the ecology, economy, and culture of Chesapeake Bay since the colonial era. Researchers at the Virginia Institute of Marine Science (VIMS) study all aspects of this species—including its ecology, physiology, and population dynamics—with an eye to conservation and a sustainable fishery.
Summer brings crab feasts—and concerns for Chesapeake blue crabs (June 2014)
NSF-funded research at VIMS shows that infectious diseases play a part in decline of crab population.
Research shows denser seagrass beds hold more baby blue crabs (September 2013)
Study is first to link habitat quality and juvenile-crab density over large areas.
Scientific survey shows dip in blue crab population (April 2013)
Number of spawning-age females up, but poor reproduction means fewer crabs overall.
VIMS researchers unravel life cycle of blue-crab parasite (Oct 2012)
Knowledge of complex life history of Hematodinium may help watermen and growers curtail spread of disease.
