| Impact Description | Hybrids between Noturus insignis and stonecat (Noturus flavus) were discovered in the Monongahela River drainage in West Virginia. Noturus flavus is native to both the river drainage studied and the Great Lakes, while N. insignis is non-native to both regions. Two one-day population surveys were completed in this West Virginia drainage. The results of these surveys, though limited, indicated that N. insignis appeared more abundant than the native N. flavus, and hybrid abundance appeared to match or exceed populations of N. flavus. |
