Biologists have been working on eliminating northern pike from Kenai Peninsula lakes and streams for years. Northern pike are native to Alaska north of the Alaska Range in areas like Bristol Bay and Fairbanks, but they were introduced to lakes in Southcentral in the mid-20th century. Since then, they’ve been stuffing themselves on salmon fry and degrading salmon runs in the Mat-Su Valley, Anchorage, and the Kenai Peninsula.
"You get down in Southcentral where pike have been on the landscape 60 years or so—we have a before and after picture," said Krissy Dunker, who manages the Southcentral Alaska Invasive Species program for the Alaska Department of Fish and Game. "We know certain systems that used to produce coho, chinook and other things, and those are gone now. It’s just pike."
