As Pacific salmon stocks continue to decline in their native ranges thanks to a toxic environmental cocktail that includes everything from poor fish management practices, fish migration barriers and climate change, it appears some salmon are finding and colonizing new habitat.
Fresh research from the University of Alaska-Fairbanks shows that chum salmon were discovered spawning in the Anaktuvuk and Itkillik rivers on Alaska’s North Slope this year. Both rivers are tributaries of the Colville River, which flows into the Arctic Ocean some 60 miles southwest of Prudhoe Bay.
