Detailed Description
U.S. Geological Survey (USGS) scientists retrieve and process an ecological processing monitoring station. Each station includes a caged native mussel (shown attached to the buoy rope) and a sampler for measuring invertebrate consumers (not shown). Scientists have found that cyanobacteria and cyanotoxins were not associated with mussel mortality at the concentrations present in Lake Erie during a recent study (2013-15), but mussel growth was lower at sites with greater microcystin concentrations.
