River habitat has been so destroyed that, though rainbow trout and Southern California steelhead are biologically the same fish, the latter has been on the federal list of endangered species since 1997. And that’s also why, any time I wanted, I could glide my fingers over the embalmed scales of a 34-inch rainbow trout—the inland sister to the steelhead—nailed to my father’s wall. Not because they’re native to the Midwest, but because they adapted to thrive all over the world.

As I reported this story, it finally dawned on me that steelhead and trout were being used interchangeably by my sources. Growing up, I thought trout belonged to my native Wisconsin. On the contrary, its progenitors are steelhead, these native Pacific Ocean residents who fight river currents to mate in the cool headwaters of Western rivers. “These fish all began as ocean-dwellers, just as life itself is derived from the ocean,” says Mark Capelli, the South-Central California steelhead recovery coordinator for the National Marine Fisheries Service. “They evolved with
