First juvenile chum salmon confirms successful reproduction for Pacific salmon in the North American Arctic
The distributional extent of Pacific salmon (Oncorhynchus spp.) in the North American Arctic is unresolved. While adult Pacific salmon have a recurring presence across the Alaskan North Slope and into the Canadian Arctic, it is uncertain if these fish are part of established Arctic populations, vagr...
