NOAA Study: Snow Crab Likely Well Adapted to Projected Ocean pH Levels

Conclusions of a two-year federal study suggests that snow crabs are well adapted to projected increases in ocean acidification within the next two centuries, with no detectible effects on embryo development larval hatching or female calcification. Authors of the study, which was published Oct. 18 in the open access online journal Plos One, said that given the number of strongly negative effects they have documents over the years it is, in all honesty, a nice change to be able to report relatively good news in regard to how high the level of carbon dioxide will affect a commercial crab species. In both years of the study, starvation-survival, morphology, condition and calcium/magnesium content were assessed for larvae. The difference in response to high partial pressure of car...

Federal Fisheries Council Slated to Act on Shellfish Issues

Snow crab and Norton Sound red king crab issues are among the issues before the North Pacific Fishery Management Council, which is meeting from Feb. 6-13 at the Renaissance Hotel in Seattle.  Major issues and final action items include the snow crab rebuilding analysis, a presentation on Norton Sound red king crab, potential of extending a temporary rule to waive vessel use caps in the International Pacific Halibut Commission’s Area 4 in the Bering Sea and measures to reduce the likelihood of data loss in the pot gear catcher/processor fleet in erring Sea and Aleutian Islands groundfish fisheries. The meeting agenda posted online at https://meetings.npfmc.org/Meeting/Details/2975 includes action memos and related documents, plus written comments submitted in advance of the council meet...

Mature Snow Crab Struggling in Eastern Bering Sea, But Immature Numbers Rising

A NOAA Fisheries analysis of the summer survey of Bering Sea crab stocks has concluded that in the wake of consecutive years of record warm temperatures numbers of mature male and female snow crab are still down, but there’s a significant increase in immature snow crab abundance, NOAA revealed Sept. 2. “Depending on how many of these young crabs actually survive to adulthood, this could be one bright spot for the fishing industry in a few years,” said Mike Litzow, survey lead and director of the Alaska Fisheries Science Center’s Kodiak Laboratory. “We are providing these early results to stock assessment scientists and resource managers to inform science and management discussions that will occur over the next few months to identify fishery management measures for the 2023 fishin...
