ERIE, Pa. -- The U.S. Department of State’s decision to lift Presque Isle Bay’s designation as an area of environmental concern was based on more than 20 years of research, much of it led by the staff at Pennsylvania Sea Grant, a partnership of Penn State Erie, The Behrend College; the Commonwealth of Pennsylvania and the National Oceanic and Atmospheric Administration.
“It took a lot of work to get to this point,” said Eric Obert, extension director for Pennsylvania Sea Grant. His involvement in the project began in 1990, when he helped tag and track 2,000 brown bullhead catfish for the Pennsylvania Department of Environmental Protection.
Bullheads are a good indicator species. Because they are bottom-feeders and have no scales, they are susceptible to the effects of pollution. The 1990 study, which was designed to estimate the population of bullheads in Presque Isle Bay, found plenty with problems: 65 percent of the fish had skin lesions.
Another 21 percent had liver tumors. That was a key reason the bay was designed an “Area of Concern” under the Great Lakes Water Quality Agreement. Environmentalists supported the move, which brought federal attention – and funding – to the pollution in the water.
