Ichthyomyzon Gagei - Geographic Distribution

Geographic Distribution

Ichthyomyzon gagei occurs in slow moving rivers and streams from Florida to southern Mississippi, Georgia, and Arkansas along the Gulf Coast west to Oklahoma and Texas (Beamish 1982). I. gagei ranges as far north as Minnesota and Wisconsin. Specifically, I. gagei have been reported to occur in the Chattahoochee river system and the Conecuh river system in Alabama, the Sabine river system in Texas and Louisiana, the Illinois river system in Oklahoma, and the Neches river system in Texas. I gagei was thought to be restricted to the southern United States; however, Becker observed I. gagei in Wisconsin in 1983 (Cochran 2000). I gagei has also been reported to occur as far north as the Spruce river and the Tamarac river in Wisconsin and Minnesota (Cochran 2012). Unpublished findings have also shown that I. gagei inhabits tributaries of Choctawhatchee Bay and the Ochlockonnee river system in Florida, the Chattahoochee river system in Georgia, and the Trinity and San Jacinto river systems in Texas (Dendy 1953).
