Crayfish engulfed in Zebra Mussels
Destructive zebra mussels have gotten into a second Kansas lake, state wildlife officials say. Zebra mussels, an invasive pest that can wreak havoc on water systems, have been found in Winfield City Lake, three years after they were found in El Dorado Lake. No one knows how zebra mussels were introduced into either Kansas lake. The Eurasian natives entered the Great Lakes region in the late 1980s, before making their way on boats and barges to other lakes and rivers in the Mississippi River basin. Zebra mussels can clog utility pipes and motors, coat rocks with sharp shells and outcompete young fish for the plankton on which they feed.
