Salmon: Running the Gauntlet
Season 29
Episode 12
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.
