Pacific salmon ‘more abundant than ever’, new study claims
Pacific salmon are generally “more abundant than ever.” That is the provocative conclusion of a new paper published in Marine and Coastal Fisheries by Greg Ruggerone of Seattle’s Natural Resources Consultants and James Irvine of the Department of Fisheries and Oceans. The study used historical commercial catch and escapement data for the entire Pacific region for both wild and commercial hatchery salmon over a 90-year period, up to 2015. There is one caveat, however: Ruggerone and Irvine analyzed only data for pink, chum and sockeye salmon. >click to read<09:13
PInks are out competing sockeye salmon for food at sea, report says
Growing numbers of pink salmon are out competing sockeyes for food in the ocean, causing the reds to grow slower and smaller. That’s the claim of a new study by Seattle and British Columbia researchers, who say the race for food ultimately affects sockeye abundance and survival. Greg Ruggerone is a senior scientist at Natural Resources Consultants in Seattle and study co-author. He says it was aimed originally at finding causes for declining sockeye runs at British Columbia’s Fraser River in 2009. Audio, Read the rest here 18:34
