Why Monster Fish are Canaries of the Colorado River

Deep in the Colorado River, monsters lurk in the murky waters — monster fish, that is, some the size of large person. But they aren’t invulnerable. Today on City Cast Las Vegas, co-host Dayvid Figler talks with National Geographic channel host Zeb Hogan, co-author of Chasing Giants, a new book about the world’s biggest freshwater fish. Zeb grew up on the Colorado, but by the time he was paddling on its waters, most of the truly big fish on our stretch of the lower Colorado had already died out. Zeb explains why monster fish are indicator species of our river’s health, and how some of our massive native fish have recently started to make a comeback.
