Grass Carp Pose a Major Risk to Georgian Bay Wetlands
Scientists in Toledo Ohio are on the front lines in the battle to stem the spread of grass carp, one of four invasive species of fish that fall under the Asian carp umbrella. Although the more public threat is bighead and silver carp near Lake Michigan, grass carp are threatening to spread within the waters of Lake Erie. This species is particularly known for it’s voracious consumption of aquatic vegetation, which could cause serious damage to both the ecosystem and the economy of the Great Lakes.
Although these invasives are not usually afforded the same threat level as the other asian carp species, a spread of reproducing grass carp to Lake Huron would severely impact Georgian Bay wetlands. GBA therefore keeps a sharp eye on the eradication and control measures being primarily carried out by US agencies in Lake Erie. Read more about where matters stand here.
