Science View S2014E20 - Uncovering the Mystery of Salmon Ecology

Salmon are a well-known food fish, yet there is a lot we don't know about their ecology. We know they return to their natal river, but how exactly do they pinpoint it? A new technique makes individual identification possible, allowing researchers to gather new information. And a small measuring device reveals the salmon's unusual behavior as they near the river of their birth. Join us to learn more about the ecology of the salmon that migrate through the North Pacific Ocean.
