Invasive grass carps have reached three of the Great Lakes, posing a serious environmental risk to the lakes and wetlands of the Great Lakes Basin (GLB), according to a new study released by Fisheries and Oceans Canada.

The voracious grass carp is one of four carp species threatening to invade the world’s largest surface freshwater system. The grass carp feeds on aquatic vegetation that provides spawning and crucial habitat while the bighead and silver carp are actually the most feared of the species. They compete with native fish and eat microscopic plants and animals.
