Victor S. Kennedy, Horn Point Laboratory, University of Maryland Center for Environmental Science; Thomas J. Miller, Chesapeake Biological Laboratory, University of Maryland Center for Environmental ScienceTopic(s):
Description:
(1) To test the hypothesis that winter mortality of blue crabs is related to winter severity; (2) To determine mechanism(s) of winter mortality with respect to interactive effects of cold temperature, low salinity, size class, and nutritional condition; and (3) To incorporate the survival and growth functions with the winter dredge survey into spatially explicit and stage-based models of Chesapeake blue crab stock dynamics to improve fishery targets.

Developing a habitat model for mysids, an important link in Chesapeake Bay food webs
Mysids are important mesozooplankton prey for many species of fish in Chesapeake Bay and are an important link in transferring energy from lower to upper trophic levels. Mysids also serve as biological vectors for benthic-pelagic coupling due to their diel vertical migration and omnivorous prey-switching behavior, which makes mysids important regulators of food web architecture. Despite their central role in coastal food webs, surprisingly little is known about mysid ecology and dynamics in Chesapeake Bay.
