Episode Info

Regarded by naturalists as one of the greatest environmental tragedies of the late 20th and early 21st centuries, the systematic depletion of Pacific salmon populations seemed to call for a swift and immediate solution. In response, engineers and biologists began a series of attempts to recreate various stages of the fish's life cycle, from spawning through death - with a life history radically redesigned via genetic engineering. This both raised serious ethical and moral dilemmas, and gave rise to a bizarre situation where the majority of consumed salmon were bred in laboratories and/or raised in tanks. Meanwhile, questions still lingered in the background about the most effective way to save the dwindling population of wild Pacific salmon. Nature: Salmon - Running the Gauntlet explores the many facets of this complex and often murky situation.
