Claim: "Alaskan fish defecting to cool Russian waters"

Not all scientists agree. Some suggest that other factors need further study, including different migration patterns of older and younger fish, whether trawl data provide a complete picture of fish populations and whether these waters are becoming overfished despite the Marine Stewardship Council's eco-label certifying that the pollock fishery is managed sustainably.

Federal scientists pointed out recently that their sampling showed the Bering waters were colder the past three summers. And yet pollock continue to appear mostly at the northwestern edge of their range.
