Carp Advance
Clip: Season 1 Episode 18 | 8m 9sVideo has Closed Captions
Invasive Asian carp have infested many U.S. waters, but not the Great Lakes — for now.
Since their introduction years ago, invasive Asian carp have infested rivers and lakes around the U.S. But they’ve been kept out of the Great Lakes — so far. Some steps have been taken to protect the lakes system, but many believe that more effective policies — and more substantial barriers — are needed to keep the fish from spreading and to reduce the numbers where they’re already established.
