The Longest Journey

From March 7, 1994 (update #20)

A rainbow trout stocked in Chicago at Lake Michigan's Diversey Harbor turned up this fall in the Mississippi River in Lousiana. The trout's long and surprising journey served as a reminder how easily organisms like fish and zebra mussels can spread via the inland commercial navigation system from the Great Lakes into the Mississippi River. Apparently, high waters and cooler temperatures this summer encouraged the 5.5 pound trout to head 1,200 miles south.

The Zebra Mussel Update was a 4- to 8-page quarterly national newsletter published by the University of Wisconsin Sea Grant Institute from May 1990 through May 1997. The ZMU documented the spread of the zebra mussel -- an exotic nuisance mussel -- through North America's freshwater environments, especially the Great Lakes, and on efforts to control it.
