ResumoThe fish fauna of the South Fork Wildcat Creek watershed, Tippecanoe, Clinton, and Tipton counties, was studied at 88 sites to evaluate species diversity and the historical and present distri- bution of fish assemblages. In 2004, we used a targeted watershed survey design (/? = 80) to spatially increase extrapolated data coverage produced by a random probability sampling of the Wabash River drainage. Few historic collections have been made in the watershed, with only three sites collected prior to 1950, seven sites from a survey of Tippecanoe County in 1994, and an additional 1 1 sites from monitoring activities between 1995 and 2003. In all, 73 species have been collected from the South Fork Wildcat Creek watershed, with only 21 species recorded from all sampling events. Dominant species include Semotilus atromaculatus, Campostoma anomalum, and Pimephales notatus. Etheostoma camurum and Luxilus cornutus have not been collected since the 1945 surveys. However, the absence of Luxilus cornutus is likely a result of taxonomic changes that resulted in Luxilus cornutus and Luxilus chrysoce- phalus being recognized as separate species. Six species (Ichthyomyzon unicuspis, Lepisosteus osseus. Notropis volucellus, Notropis wickliffi, Pylodictis olivaris, and Lepomis microlophus) have not been col- lected since 1994. In 2004, an additional 12 species {Campostoma oligolepis, Nocomis biguttatus, Xote- migonus crysoleucus, Phoxinus erythrogaster, Carpiodes velifer, Carpiodes carpio, Ictalurus punctatus, Noturus gyrinus, Gambusia affinis, Lepomis gulosus, Poxomis nigromaculatus, and Aplodinotus grunniens) were the first verified records for the watershed.
