Synopsis
North America is under attack by a sly and wily aquatic invader. Introduced in the ‘70s for the purpose of cleaning up algae in fish ponds, the aggressive Asian carp escaped into the Mississippi river system during floods. The 50-kilogram bottom feeders have advanced north at a surprising rate, becoming a familiar sight with their frenzied and often physically threatening mass leaps into the air. Despite their fascination with this newcomer, scientists on both sides of the Canada-U.S. border agree this invader is a threat we need to take seriously.
