Here’s a story in National Geographic about Russian Kamchatka salmon that has many similarities to what happened to Northwest salmon and underscores the importance of habitat and fisheries management.
“Russia’s remote Kamchatka Peninsula has some of the richest salmon runs in the Pacific, sustaining animals and communities. Now the fish need help.
…It’s a wild place, in which brown bears and Steller’s sea-eagles thrive on a diet rich in fatty fish. About 350,000 people inhabit Kamchatka Krai (its label as a governmental region), and they too are highly dependent on fish. In fact, you can’t begin to understand Kamchatka without considering one extraordinary genus: Oncorhynchus, encompassing the six species of Pacific salmon.”
