Phase 2 Studies: Impacts of Commercial Navigation Traffic on Freshwater Musselsat the W.H. Zimmer Station, 1989-90 Baseline Studies

摘要

Qualitative and quantitative baseline data were obtained at nine and six sites,respectively, at a mussel bed located on the Ohio River near the W. H. Zimmer Station, in July 1989 and September 1990. This information, in conjunction with data to be collected after the power plant has operated for at least 1 year, will be used to assess the effects of coal deliveries by barge on freshwater mussels. Total species richness (24) was similar to that at other large-river mussel beds.
