Temporal Variation in Black Spot Disease in Three Common Species of Cyprinids From the Susquehanna River

Elaine Langone Center, Terrace Room

We examined spotfin shiner (Cyprinella spiloptera), spottail shiner (Notropis hudsonius), and bluntnose minnow (Pimephales notatus) for black spot disease. These fishes were collected from seven years of seine samples from the Upper Susquehanna River. Our goals were to assess variation in the prevalence (=Nhost/Nfish), mean intensity (=Nspots/Nhost), and abundance (=Nspots/Nfish) of disease among the years sampled.
