A University of Alaska Fairbanks team last month found about 100 chum salmon that were spawning or had just spawned in the Anaktuvuk and Itkillik rivers.
Peter Westley of the University of Alaska Fairbanks holds two chum salmon at the Anaktuvik River on Sept. 22. Westley, an associate professor at UAF’s College of Fisheries and Ocean Sciences, led a team that found about 100 of the spawning fish last month on the North Slope. The discovery backs up the hyphothesis that climate change is causing salmon to shift their range north.
“I was just really happy to see it all come together,” said Westley, who is studing salmon population shifts. “It felt like we were kind of looking for a needle in a haystack.” If liquid water remains there throughout the year, there is support for a more permanent chum salmon presence, he said. “If they freeze solid, it’s pretty much the end of the road,” he said. “Salmon eggs can’t survive if they freeze.”
The catalyst for the spawning-salmon project was an Arctic salmon workshop held by the Alaska Sea Grant program in Anchorage last December.
