Opinion: Columbia Basin Collaborative anything but collaborative
The Columbia Basin Collaborative was introduced last year by the governors of the four Northwest states to help move the region past unending litigation around endangered salmon species. Our initial feedback was that the collaborative should expand beyond the four Northwest states, recognizing that salmon in Canada, Alaska, and Northern California have seen similar Chinook salmon declines the past 50 years by a shocking 65%. This finding was recently confirmed by the region’s Independent Science Advisory Board. Unfortunately, recent developments within the collaborative are causing concern. Instead of looking for new solutions, it seems the collaborative is essentially a recall effort aimed at removing the lower Snake River dams. >click to read< 10:22
Study says predators may play major role in chinook salmon declines
A new study shows that increased populations of seals and sea lions are eating far more of Puget Sound’s threatened chinook than previously known, potentially hampering recovery efforts for both salmon and endangered killer whales. Seals and sea lions are eating about 1.4 million pounds of Puget Sound chinook each year — about nine times more than they were eating in 1970, according to the report, published online this month in the Canadian Journal of Fisheries and Aquatic Sciences. Most of these chinook are small fish migrating to the ocean, which ultimately reduces the number of adults returning to Puget Sound. The study estimates that seals and sea lions are decreasing potential returns by about 162,000 adult chinook each year. That’s twice the number eaten by killer whales and roughly six times as many as caught in Puget Sound by tribal, commercial and recreational fishers combined. Read the rest of the story here 21:16
