Invading Species: Asian Carp Take Over American Lakes and Rivers | Global 3000

Millions of Asian carp are wreaking havoc in the Mississippi River. They were originally imported by fish farmers, who used them to eat algae in their fish ponds. But some of the fish managed to escape into the Mississippi, where they reproduced rapidly.The Asian carp are taking over the river and disrupting the balance of the species there. Now fishermen have been brought on board to help. It's not an easy job - Asian carp can jump up to two meters out of the water, and have even injured fishermen.
