Duane Chapman is a researcher with the US Geologic Survey exploring high tech ways to control the exploding Asian carp population. But he wasn't always working to contain the invasive species.

Dan Collision and Elizabeth Meister are two journalists who went out on the Illinois River to look into that argument. Plus, Rachel Friedman's protest.
