Prehistoric fish could be a weapon against Asian carp

Aug 4, 2016

It has scales so tough Native Americans once used them as arrowheads.

It can grow longer than a horse, and it loves to munch on Asian carp.

It's the alligator gar!

This ancient fish is found in the south, but they're being restocked in rivers and lakes as far north as Illinois in hopes they might control Asian carp and, in turn, protect the Great Lakes. 

Alligator gar expert Allyse Ferrara joined us today to talk about the giant fish and how it might help reduce the number of invasive Asian carp getting into the Great Lakes.
