Asian grass carp have invaded the Great Lakes

grass carp

That’s the conclusion of a Fisheries and Oceans Canada (DFO) report on grass carp, 48 examples of which were found in open waters or Great Lakes tributaries last year. The problematic fish have “arrived” in Lake Michigan and Lake Erie and are “very likely” to become established within 10 years, according to the peer-reviewed study, which lays bare in frank terms an unfortunate reality.

That’s the bad news. The good news is that grass carp, while problematic, are not the same level of threat posed by the plankton-gobbling, leaping bighead and silver carp that are advancing toward the Great Lakes through Illinois waters.
