VIDEO: How Many Sport Fish Can Lake Michigan Support?
Who’s eating whom in Lake Michigan?
The emergence of a few bad actors has made it difficult to answer that question.
That’s why University of Wisconsin-Milwaukee researchers are studying the impact of aquatic invasive species — specifically round gobies — on Lake Michigan food webs.
Gobies are a ravenous and aggressive fish species that invaded Great Lakes in the early 1990s. They subsist on tiny bottom-dwelling organisms and feed on baby quagga mussels for a side dish, scientists say.
Food web research from Wisconsin, Illinois and Indiana may determine whether Lake Michigan has reached its carrying capacity or if it can support a legion of gobies without further environmental degradation.
