(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.
