One person's trash is another's treasure. So it is with so-called trash fish or rough fish. I talk about these animals with Scott Leysath, host of the TV show "Dead Meat," which focuses on offbeat fish and game, as well as Tom Dickson of the Montana Dept. of Fish, Wildlife and Parks; Dickson co-wrote a book on rough fish called "Fishing for Buffalo."

We go into why some fish are hated on, as well as why this is, mostly, unjust. We also go into how to catch and eat many of North America's least liked fish.
