Alaska officials have cancelled the upcoming snow crab season, due to population decline across the Bering Sea. The fall Bristol Bay red king crab harvest will not happen. The winter harvest of smaller snow crab has also been cancelled for the first time. The causes of the population collapse are being researched but likely include increased predation and stresses from warmer water, which the US Environmental Protection Agency (EPA) believes may have prompted the crabs to shift away from coasts.
