Context

Pacific salmon are salmonids in the genus *Oncorhynchus* that hatch in freshwater, spend most of their lives in the ocean, and return to freshwater to spawn; many species die after spawning [2]. They are anadromous and semelparous [2]. Species include coho, sockeye, chum, Chinook, pink, and cherry [2]. They are found in the North Pacific basin [1]. NOAA describes their lifecycle: born in freshwater streams, migrate to estuaries, enter the ocean, and return to spawn [2]. Britannica notes they are confined to temperate and Arctic waters of the North Pacific [3].
