Abstract

During the last 45 years, the blacknose shiner (Notropis heterolepis) has been restricted to a three county area in northwestern Iowa. We surveyed locations where this siltation-intolerant species had been captured to update the status of the fish in the state. Streams were blocked with nets on both the upstream and downstream ends of sample areas, and fish were collected with a backpack electrofisher and seines. Lakes where the blacknose shiner had been found were also sampled. No blacknose shiners were found and several possible explanations are offered for their absence from historical sites.
