Coho Salmon

Coho Salmon (Oncorhynchus kisutch) are also known as Silver Salmon. Coho Salmon rear in fresh water for up to five years. In Alaska, Coho Salmon is the last Pacific salmon species to spawn in a calendar year. Spawning takes place throughout the autumn. At this time stream water levels drop and clarity increases as glacial water sources freeze up for the winter leaving clearer groundwater as winter stream flow.
