Norton Sound residents have reported salmon die-offs in unusually large numbers during the last week. According to the Norton Sound Economic Development Corporation (NSEDC), dead pre-spawned pink salmon were found in multiple river systems over the weekend.

Dead salmon and whitefish found along the banks of the Yukon River.

As record high temperatures swept Alaska, many people said that the heat was killing them. For Kuskokwim salmon, it was actually true.

Warm water near Golovin is hurting pink salmon. Many salmon caught had red speckled dots on flesh, raising concerns about food safety. Female pink salmon were seen dead in the bay.

"Over 40 dead dog salmon, one shee fish, one lush fish, and two delmaga all dead along the river going towards the creek opening."

“The exact reasons why the return fell at the lower end of the forecast range are unknown at this time, but poorer than average marine survival is a leading candidate.”

Dead chum salmon have been spotted floating down the Yukon river. Water temperatures are measuring at 70 degrees, the warmest in recollection.

"Our temperatures reached 83 degrees, and seem to be getting hotter! We think that maybe the warm water has something to do with the humpy die-off?"

We observed more than 50 otherwise healthy (not spawned out) dead fish including pink and chum salmon and white fish

Salmon are dying along the Andreafsky River and Lower Yukon River before spawning out. Water surface temperatures have been unusually warm, at one point reaching 70 degrees Fahrenheit.
