SOCKEYE SALMON, ONCORHYNCHUS NERKA, AN IMPORTANT AQUATIC RESOURCE
FIGURE 8.28 Sockeye salmon, Oncorhynchus nerka, are native to the North Pacific region, where they spawn in river and lake ecosystems from the Klamath River of California and Oregon to Alaska, Siberia, and the island of Hokkaido, Japan. The species is an important source of income and nutrition to local communities throughout its range. For example, in recent years the sockeye salmon fishery of Bristol Bay, Alaska (shown in action here), alone has been valued at over $100 million annually.
