Chum Salmon
Oncorhynchus ketaAlso known as Dog Salmon, Keta Salmon, Calico Salmon, Silverbrite Salmon
Chum salmon undertake extensive ocean migrations across the North Pacific before returning to their natal freshwater streams to spawn. During their ocean phase, they display a silvery coloration, but spawning adults develop dark olive bodies marked with striking purple and crimson vertical bands, along with hooked jaws fitted with large teeth. Dying shortly after spawning, their carcasses deliver critical marine-derived nutrients that fertilize coastal rainforest ecosystems.
