Path of the Perch

White perch (Morone americana) is a fish native to the east coast of the U.S. Over the decades it has been introduced to several other river systems in North America, where it has established large populations. But they're not quite sure how dozens of the fish ended up in Barrow Pit, Iowa, part of the Keg-Weeping Water drainage area. It's the first documented evidence of white perch in that state. Read the report here, or the history of the species here.
