Description:

Lipofuscin (LF)-based age determination of blue crabs will be used to measure the rate at which juvenile blue crabs grow and recruit into Chesapeake Bay peeler and hard crab fisheries during summer and fall months. We seek to develop a temperature-based growth model for juvenile blue crabs and apply this model to predict monthly fishery yield patterns.
