Gulf of Alaska cod stocks at all-time lows
Pacific cod numbers in the Gulf of Alaska are at all-time lows, according to early looks at data collected from the 2017 summer survey. Steve Barbeaux, a fisheries biologist for the Alaska Fisheries Science Center in Seattle, said scientists believe that the warm water mass known as the blob may be responsible for the low numbers. “It seems that this warm water that occurred that we’re calling the blob may have increased natural mortality for the 2012 year class and probably 2014, 2015, and 2016 as well,” Barbeaux said. click here to read the story 13:32
