Blue Crabs

We collaborated with population geneticist, Dr Joe Neigel, University of Louisiana at Lafayette to investigate the effects of the Deepwater Horizon Oil spill on Blue crabs. Our Blue crab project is funded by the Gulf of Mexico Research Initiative.

Blue crabs, Callinectes sapidus, are one of the most economically and ecologically important species in the Gulf of Mexico. Population sizes fluctuate greatly from year to year for reasons currently unknown. We are currently investigating how larval dispersal changes during a year and from year to year and how population connectiv
ity was affected by the Deepwater Horizon oil spill. This study included field experiments, lab-based ecotoxicology experiments, mathematical modeling and development of a high-resolution particle-tracking model to simulate larval dispersal in the GOM.
