Warm water boosts the metabolism of cod, causing them to eat more, and this increased demand on the food supply led to smaller fish, making the cod more susceptible to predation and environmental factors. The council also reduced the allowable catch for arrowtooth by about 23,000 metric tons to protect halibut stocks, which have declined by 20%. The North Pacific Fishery Management Council hit the pause button after studies found a roughly 70 % decline in Pacific cod. Regulators chopped the fishery’s total allowable catch by about 80 percent Saturday, following a dramatic decline in Gulf of Alaska Pacific cod stocks.

Cod is Alaska’s second largest commercial fishery by volume, bringing in $186 million in 2015. Scientists believe the decline is likely due to “the blob,” a deep body of warm water that moved into the Gulf three years ago. Stocks are expected to continue declining as warm temperatures were tough on the juvenile cod, with the effects of high mortality and poor recruitment hitting bottom in 2020.
