Adapting to Warming Waters Will Have Role in Future Pacific Cod Spawning
Pacific cod have expanded their summer travel range into the northern Bering Sea due to warming waters to the south, but appear to be migrating back to their typical spawning grounds in winter where their eggs are more likely to survive and hatch.
That’s what scientists at the Alaska Fisheries Science Center in Seattle say they’re observing in their ongoing research on how Pacific cod will find suitable spawning habitat as new climate conditions in the ocean evolve in the 21st century.
“There is always potential for adaptation, but it is typically slow,” said ecologist Lauren Rogers, also a co-author and colleague of Jennifer Bigman, the lead in the latest NOAA Fisheries research release on spawning habitat in the Bering Sea.
“I think the bigger question is whether they will adapt to ...
