Salmon: Running the Gauntlet

Season 29 Episode 12 | 53m 19s

The parallel stories of collapsing Pacific salmon populations and how biologists and engineers have become instruments in audacious experiments to replicate every stage of the fish's life cycle. Our once great runs of salmon are now conceived in laboratories, raised in tanks, driven in trucks, and farmed in pens. Here we go beyond the ongoing debate over how to save an endangered species.
