INKSTER, Mich. - Officials say an invasive fish called the round goby appears to be making its way up the Rouge River in southeast Michigan.
Sally Petrella of the non-profit group Friends of the Rouge tells the Detroit Free Press (http://on.freep.com/TqJMhp ) that a team found more than a dozen of the greedy predators while sampling sections Friday of the Lower Rouge River in Inkster. She says there's a "huge potential for wiping out a lot of native fish."
Gobies hang around prime spawning areas and gobble up eggs laid by trout, whitefish and other species important to the Great Lakes region's commercial and sport fishing industries.
The find comes as groups work with cities and businesses to improve fish habitats by reopening sections of the Rouge River that were blocked by dams.
