More research needed to protect Great Lakes from Asian carp

In order to truly assess the threat to native fish species, there needs to be much more research into just how Asian carp and similar invasive species impact local and regional ecosystems. John Chick, a researcher whom IISG has provided past funding for, is one of the people working to gain a clearer picture of just what’s happening under the surface. 

"'We suspect at some point there will be a real crash in the populations of some of these native fishes,' said John Chick, an aquatic ecologist with the National Great Rivers Research and Education Center on the Mississippi River near St. Louis.

While years of study have turned up ominous signs that the carp are capable of crowding out other species and changing ecosystems, the worst-case scenario scientists expect to unfold hasn't yet been realized. Some scientists say that dire predictions about the damage carp can do may be premature. That makes the research Chick and his colleagues are conducting critical: It likely will influence how the debate over managing waterways made vulnerable by carp plays out in Congress and the courts."
