Larval Biology of Invasive Crabs in Delaware Bay

We are conducting laboratory experiments on vertical swimming behaviors of lab-reared larval invasive mitten crabs (Eriocheir sinensis) and shore crabs (Hemigrapsus sanguineus) in response to exogenous environmental factors (e.g., light and pressure), and quantifying endogenous activity rhythms. Data from these experiments are being used in a circulation model of Delaware Bay to better understand the threat of invasion from this species now, and under future conditions of environmental change. This project is funded through Delaware Sea Grant/NOAA.
