Alaska salmon have shrunk so much that a famed Seattle restaurant is rejecting some and Whole Foods overhauled its guidelines Author: Kim Chipman, Bloomberg Published 2 hours ago Share on Facebook Print article At OBI Seafoods, a sprawling operation with outposts throughout Alaska, there’s all sorts of extra machinery for workers to master. At Whole Foods Market, there are new guidelines for purchasing salmon from wholesalers. And at Ivar’s, a fixture on Seattle’s waterfront for eight decades, the chef is sending back skimpy salmon delivered to his kitchen. Behind all these changes is an alarming trend that’s been building for years: The giant schools of wild Pacific salmon that can turn Southeast Alaska’s ice-cold waters into a brilliant orange blur are thinning out, and those that do survive are smaller.

Earth's magnetic field may guide salmon, study says

Earth s magnetic field may guide salmon, study says January 14th |   Is it a coincidence that one of the world s largest mineral deposits is located near the world s largest sockeye salmon spawning grounds at Bristol Bay? And if the likes of a Pebble mine removed the bulk of those deep deposits that also create the world s magnetic field, could it disrupt the salmon s ability to find their way home? A study, funded by Arron Kallenberg of Homer, founder/CEO of Wild Alaskan Company and a third generation Bristol Bay fisherman, aims to find out. It s not even been 10 years since we ve discovered that salmon, sea turtles and other marine species are using the Earth s magnetic field as a way to know where they are and to make important navigation decisions. But what is the magnetic environment that they need to thrive, and what might humans be doing that might keep them from thriving, said Dr. Nathan Putman, a senior scientist at Texas-based LGL Ecological Research Associat
