Large blooms and their subsequent decay could significantly alter the carbon and nitrogen in the estuary. Such alterations could in turn upset the production and abundance of fish and shellfish. The researchers: Hans Paerl, Institute of Marine Sciences, University of North Carolina at Chapel Hill Donald Stanley, Institute for Coastal and Marine Resources, East Carolina University Robert Christian, Department of Biology, East Carolina University Two costly diseases The problem: contaminated shellfish and red-sore disease in fishes Contaminated shellfish and disease-ridden fish are lost resources to North Carolina's fishermen. Fishermen are prohibited from harvesting contaminated oysters and clams. And fish stricken with diseases such as red-sore usually die or are unsellable to seafood processors. Shellfish contaminated by discharges from sewage treatment plants, faulty septic systems, land run-off and boat waste discharges can carry serious viruses. Hepatitis A is one of the most serious viruses they transmit. Last year in the state of New York, forty people contracted hepatitis A after eating contaminated clams. Another 300 to 400 people came down with gastroenteritis. After finding a portion of the clams harvested from approved open waters, state health officials warned New Yorkers not to eat any raw shellfish. While the outbreak was limited to New York state, officials from the Center for Disease Control believe outbreaks may be occurring in other areas, yet going unreported. The research: studies into how shellfish are con- taminated with hepatitis A and how fish are afflic- ted with red-sore disease Being surrounded by vials of cultivated viruses might make some folks nervous, but for Mark Sobsey it's part of the job. Sobsey has been conducting Sea Grant studies into the detection, occurrence, survival and fate of e
