Pollock ranging further north?

The NOAA trawl survey of the southern Bering Sea has completed and preliminary results suggest lower abundances of pollock and cod than anticipated. The Cordova times recently released an article by Margaret Bauman with an interview of Lyle Britt, a research fisheries biologist with NOAA’s Alaska Fisheries Science Center in Seattle. Data collected suggest a warming trend and showed pollock collected much further north than expected. Researchers believe that this may be due to the lack of a cold pool that normally functions as a barrier to dispersal. Formal results have yet to be released, but if you are interested in Alaska Research Surveys a wealth of information can be found on NOAA's website
