In an industry full of booms and busts, the Kotzebue commercial chum salmon fishery is exploding.

After decades of fluctuation, including a point where the fishery all but ceased to function, it's back this year, and fishermen are slaying.

So far, about 80 permit holders -- about 69 of which fish on a consistent basis -- have brought in 4.45 million pounds of salmon. On July 28, those fishermen brought in 534,000 pounds of fish to the fishery, 10 times more than the average of 50,000-70,000 pounds of fish that usually get caught each day.
