Abstract

In the mid-1990s, Iowa Department of Natural Resources (IDNR) Fisheries Bureau biologists began receiving reports from anglers of a parasitic lamprey attached to fish taken immediately downstream from Rathbun Lake on the Chariton River in south-central Iowa; these reports have continued to present. In 2002, the IDNR received and identified a chestnut lamprey (Ichthyomyzon castaneus Girard) from an angler who removed the lamprey from a common carp (Cyprinus carpio Linnaeus) he captured. This record was the first for a lamprey from the Chariton River drainage in Iowa. Five additional specimens of chestnut lamprey have been collected and identified since this specimen was found, all from the same location. The Rathbun Lake tailrace is one of only a few locations on Iowa's interior rivers and streams with verified records for chestnut lamprey.
