Here's an article I though interesting about an out of place Catfish: Amazon River Catfish Found In Minnesota DULUTH, MN--Minnesota Department of Natural Resources personnel netted a surprise during a routine fisheries census of Caribou Lake near Duluth this past summer. "We were completely startled," says John Meerbeek, one of two DNR employees who netted a Lima Shovelnose catfish, an Amazon River native. "Even before we untangled it, we could tell it wasn't native. We figured it was an aquarium fish from the Ictaluridae (catfish) family." The fish was held at the French River Hatchery, where it died a few days later.
