Unusual weather in Alaska’s Interior is causing a slowdown of an expected sockeye run on the Copper River. On Wednesday, state Fish and Game fisheries managers issued a notice delaying the start of the Copper River personal use, or dipnet, fishery in the Chitina subdistrict. Mark Sommerville is the area management biologist in Glennallen. He says an unusually late breakup on the Copper and recent soaring temperatures are combining to create conditions that fish don’t like.
