Autumn salmon are making their upstream run! You can watch them up close at Totoro-do.👀 Salmon are born in rivers, grow in the sea, and eventually return upstream to their natal rivers. The fry that hatch from eggs in the river head to the sea in spring with the snowmelt, spend summers in the Bering Sea, and winter in the Gulf of Alaska. About four years later, the mature salmon migrate southward from the Bering Sea along the Kuril Islands and, around September through November, return to the rivers where they were born to spawn.
