The Ocean Doctor makes a house call to the ailing Gulf of Mexico, visiting southern Louisiana in the heart of the Mississippi River delta to learn firsthand the damage wrought by the BP Deepwater Horizon oil spill disaster. We visit again with fishing guide Ryan Lambert and also visit East New Orleans’ Vietnamese community — a community especially hard-hit by Katrina, and now the BP spill – where they are considering sustainable, land-based aquaculture as an alternative to fishing the Gulf. Father Vien Nguyen gives us the grand tour.
