This research program investigates the physical factors that influence the return of blue crab (Callinectes sapidus) megalopae (larvae) to Chesapeake and Delaware Bays. Blue crab larvae are spawned at the mouths of the estuaries and spend ~1 month in coastal waters where they go though several stages of development. They re-enter the estuaries in the megalopae stage (pictured to the right). Wind and river flow influence how many return to estuarine nursery areas and, hence, future abundances of juveniles and adults. The goal of our program is to better understand megalopae behavior and use this information with computer simulations to better understand and predict the influence of environmental variability on blue crab populations.
