LUDINGTON -- A bug-eyed fish that snuck into the Great Lakes in the ballast tanks of ocean freighters two decades ago is now laying siege to Lake Michigan, according to new research data.
The round goby population enjoyed a population explosion in 2008. The invasive species accounted for nearly one-quarter of all prey fish in the lake last year, by weight, according to data compiled by the U.S. Geological Survey's Great Lakes Science Center.
"We're seeing a dramatic increase in gobies," said Chuck Madenjian, a research fishery biologist with the USGS. "Round gobies are now a substantial part of the total biomass of prey fish species ... we caught gobies in 300 feet of water."
