Bigmouth Shiner

Notropis dorsalis

Bigmouth Shiner occurs in medium-sized streams with clean gravel. It is native to five watersheds in the western half of the state. It has also become established as a non-native in the Chemung watershed, with records since 1981. This species still inhabits most of its range in the Genesee, while there may be decreases in the Erie watershed. Its range also appears stable in the Allegheny, where it is labeled as an Allegheny subspecies. Bigmouth Shiner appears to be gone from the Oswego and Ontario watersheds where it was thought to have been a relict. Since 1977, it can still be caught in about half of its former range.
