Flora and Fauna

The Alaska Peninsula and Bristol Bay are home to the world's largest sockeye salmon runs in large part because the Alaska Peninsula is host to so many large lakes, which are an important element in the lifecycle of Oncorhynchus nerka, sockeye salmon. These salmon, after returning from their short life at sea, swim into the lakes and their contributing streams to spawn. Their offspring, or fry, overwinter in the deep and food-abundant depths of these lakes until their migration to the sea in one or two years.
