SHELLTOWN, MD, USA - 1997/09/25: Menhaden fish with open sores from the flesh eating Pfiesteria disease outbreak in the Pocomoke River along the Chesapeake Bay September 25, 1997 in Shelltown, Maryland. The outbreak caused a loss of $43 million dollars in fishing revenue and is believed to be caused by the runoff of chicken manure from farms in the area. (Photo by Richard Ellis)
