Pacific salmon can now reproduce in Alaska’s Arctic, researchers find

A single juvenile fish found in a lagoon on Alaska's North Slope proved salmon can reproduce in the North American Arctic.

Waist-deep in the waters of Jago Lagoon off Alaska’s North Slope, biologist Vanessa von Biela and her research partners got a big surprise in the summer of 2017 when they were sorting through Arctic fish that had been captured in a test net.  Among the hundreds of Arctic cisco in the net was a juvenile chum salmon — the first direct proof of successful salmon reproduction that far north in North America.
