Why such avoidance of a simple and very basic question I would say over fishing over a period of time would have FAR more effect on the population. Crab have survived this long with changing WEATHER. Couple degrees up top don't mean shit at 8,000FT deep. Also crab are a moving biomass which is allows them to move where conditions suit them Quote Link to comment Share on other sites More sharing options...

Gold Member Stephen Hawking Posted May 3, 2023 Gold Member Share Posted May 3, 2023 1 hour ago, BOHICA said: High water temps, highest recorded mortality rate. Hmmm. Interesting. Dots are pretty simple to connect. “In those two years, 2018 and 2019, the Bering Sea was very warm,” Ben Daly, with the Alaska Department of Fish and Game, said. In 2019, Fish and Game recorded the crabs’ highest mortality rate. How exactly are they recording the mortality rate? Probing the bottom with a mini sub? Underwater listening equipment to record the crab death screams? 2 Quote Link to comment Share on other sites More sharing options...

Underwater listening equipment to record the crab death screams? They do surveys, estimations, and such. For example snow crab declined like 90% over 3 and it’s why that fishery is closed. “Clearly, there’s no smoking gun,” says Stichert. “We’ve been in this trend for quite some time, and something is preventing the young crab from entering the fishery.” Among theories considered by biologists, ocean temperature fluctuations and subsequent seasonal sea ice formation could have an adverse effect on the survival of larval crabs during the first month or two after they hatch, when they live as pelagics and are subject to the whims of ocean currents. “Water temperature affects currents,” Stichert says, “and they may get dropped into a less complex bottom structure.” That can mean falling into a land of starvation or a land of predators—or both. The total mass of sea ice in the northern hemisphere has declined by 13 percent in the last decade, and the lack of ice affects water temperatures. While cold north winds dominated northern regions of the Bering Sea, a prevailing trend of warm, southerly winds prevented ice formation south of Bristol Bay and the Pribilof Islands. “Ten years ago, it was not uncommon for ice to hit the north side of the Alaska Peninsula as far south as the Pribilof Islands,” Stichert says. At the same time oceanographic data notes the shrinking of the “Cold Pool,” a body of water with temperatures of 0 degrees to 2 degrees Celsius. The Cold Pool serves as a barrier separating species such as pollock and cod from the northern reaches of the Bering Sea. Its absence from 2017 to 2019 has had a profound effect on species distribution, according to the 2021 Eastern Bering Sea Ecosystem Status Report, put out by the National Oceanic and Atmospheric Administration. Some of the same ecosystem changes are suspect in the opilio crab crash. Last year the industry had expected a TAC of around 45 million pounds, which would have been similar to 2020-2021, but trawl surveys revealed a 99 percent drop in mature females and a substantial drop in the abundance of mature males. The North Pacific Fishery Management Council set the TAC for the 2021-2022 season at 12.4 million pounds, but the State of Alaska which jointly manages the fishery, opted for a much-lower TAC and set it at 5.6 million pounds. “We saw an 80 to 90-percent decline in all sizes within the population,” says Stichert. The trawl surveys also found more than 50 percent of Pacific cod biomass had migrated to the northern Bering Sea. Those fish are normally held south of the crab rearing areas by the Cold Pool. But in its absence, cod moved in and have been blamed for predation on the opilio crab. Another oddity is that the crab had marched westward, into deeper water, suggesting they were looking for colder subsurface sea temperatures. Though some speculated that the crab traveled outside of the survey areas, scientists who advise the council are convinced that the crabs’ disappearance is linked to a cataclysmic mortality event. https://www.nationalfisherman.com/alaska/surveys-bode-bad-seasons-ahead-for-bering-sea-crabbers Quote Link to comment Share on other sites More sharing options...
