"The one-sided love affair between the California sea lion and the succulent salmon of the Columbia River has been going on since time immemorial, with salmon typically coming out the losers in the affair.
But with many West Coast salmon runs now endangered or threatened, fisheries officials have been struggling to find ways to keep salmon off the menu, at least near Bonneville Dam on the border between Washington and Oregon, where sea lions have learned to gather for easy feasts. In 2007, sea lions ate about 3,800 of the 88,474 salmon that passed through the dam."
