Abstract:

Recent stream survey results and historical records compiled in the Minnesota Natural Heritage Program database were reviewed to determine the distribution and sampling gear vulnerability of the crystal darter (Crystallaria asprella) in the Mississippi River Basin of southeastern Minnesota. Including Wisconsin boundary rivers shared with Minnesota, the species has been reported from five major watersheds within the basin at 22 localities which encompass five Minnesota and six Wisconsin counties. Survey gears which have successfully sampled crystal darters include seines, boom and stream electroshockers, and deep water trawl nets.
