The snow crab fishing season in Alaska was canceled on Monday.

According to CBS News, an estimated 1 billion snow crabs vanished from the sea. The collapse could cause many fishers to leave the business.

Dean Gribble Jr., a crab boat captain who has fished snow crab since the 1970s, told NBC News that it would be life-changing for people. A lot of these guys with families and kids have no choice but to leave. The hammer will fall on the crew.

The snow crab stock looked promising in recent years, sparking hope amidst the decline of Alaskan king crab. For the second year in a row, the Alaska Department of Fish and Game canceled the red king crab season.

The snow crab population crashed this year and scientists need to figure out what happened.

The polar regions are warming faster than the rest of the planet due to greenhouse gas emissions. Some of the world's most popular crabs may have crashed due to rising water temperatures.

We're on the way. Miranda Westphal, an area management biologist with the Alaska Department of Fish and Game, told NBC that it's difficult to predict the future of a stock that is subject to Mother Nature. They require time and space to rebuild.

Fishermen were hoping for a snow crab surge.

The largest juvenile snow crab spike in the fishery's history was recorded by the ADFG. The juvenile population was still growing. The water temperature in the Bering Sea went up.

A survey was not conducted in 2020 due to COVID-19. The biggest crash we've ever seen in snow crab was discovered when the agency returned in 2021.

The Washington Post reported that the stocks were down.

That was not what I thought it would be. I don't think anyone saw this coming. The warm waters are thought to have contributed to the deaths of young crabs.

The agency requires the stock to be at a certain level.

The condition of the snow crab in the Bering Sea makes it necessary for management to focus on conserve and rebuild.

The stock is held by the company. Efforts to advance our science and understanding of crab populations are underway.
