Genetic Testing Uncovers High Infection Rates in Commercially Vital Bering Sea Crabs

A recent study using advanced genetic testing has revealed alarmingly high infection rates of bitter crab disease in Tanner and snow crabs, two commercially important species in the Bering Sea. Scientists estimate that up to 42 percent of Tanner crabs and 36 percent of snow crabs were infected during the study period, considerably higher than previous estimates.

Bitter crab disease, caused by microscopic parasites, has been shown to be lethal in a lab setting. Traditional detection methods which relied on visual observations and blood sample analysis, suggested infection rates of less than 10 percent. However, the more sensitive genetic methods used in this study show a drastically different situation.

“That is a nearly four-fold increase in the annual prevalence levels previously detected,” said Erin Fedewa, a fisheries biologist at NOAA’s Alaska Fisheries Science Center.

King Crab Fishery in Southeast Alaska Approved

by Nigel Stacey

In a significant policy shift, the Alaska Board of Fisheries has approved a proposal to permit a limited commercial harvest of red king crabs in Southeast Alaska. This decision, approved during the board’s Southeast and Yakutat Finfish and Shellfish meeting in Ketchikan from January 28 to February 9, 2025, changes previous regulations that required an estimated biomass of legal male red king crabs to exceed 200,000 pounds before opening a commercial fishery. This threshold had resulted in only three commercial red king crab seasons in the region over the past two decades.

The Alaska Department of Fish and Game (ADF&G) and commercial fishers agreed that the 200,000-pound requirement was based on outdated market conditions, which suggested that processors needed this volume to operate profitably. Nels Evens, Executive Director of the Petersburg Vessel Owner’s Association, emphasized that this threshold was not biologically necessary but was established due to past market demands.

The newly approved proposal allows regulators to open a small-scale commercial fishery even when the biomass is below the previous threshold. This change will provide economic opportunities for local crabbers while maintaining sustainable management of the red king crab population. Specific details regarding harvest limits and management will be determined by ADF&G as well as stakeholders.

Red King Crab Harvesting Opens in the Bering Sea

by Nigel Stacey

After a two-year closure due to insufficient stock levels for fishing, the Bristol Bay red king crab fishery in Alaska is scheduled to reopen at noon on October 15, 2023. The established quota for this reopening is 2.15 million pounds, slightly less than the 2.6 million pounds set in 2020.

Jamie Goen, executive director of Alaska Bering Sea Crabbers, said members are happy to return to their work on the water. However, they are committed to ensuring minimal impact, aiming for the sustainability of the crab resource for future generations.

“They are tracking closely the science around the health of crab stocks and want to help crab continue to rebound,” she said. We’re adding extra measures this season during our directed pot fishery for crab to reduce our interactions with crab. We’re increasing communication with the fleet on best handling practices, clean fishing areas, and opportunities to share gear.”

Commercial Crab Fishery Closed

by Joseph Stacey

Due to disappointing population surveys once again this year, the commercial harvests of red and blue king crab in Southeast Alaska will remain closed during the 2023–24 season. Stock assessment models have revealed a biomass of just 188,899 pounds, falling short of the 200,000-pound threshold required to authorize the fisheries.

The closure of the fishery, due to insufficient biomass, is not unexpected for those overseeing stocks. Insufficient biomass has prevented the fleet from deploying pots since 2017.

On a positive note, the outlook is promising for the fishery in the upcoming year.

King Crab Hatcheries in Alaska

by Nigel Stacey

Western Alaska has been hit hard economically by the long-term decline in crab stocks. This year, the Bering Sea snow crab total allowable catch was reduced by 90 percent while the Bristol Bay red king crab fishery has been closed entirely. This week, changes were made to House Bill 41, a bill allowing designated non-profits to grow shellfish in hatcheries, moving the bill closer to becoming a law. HB 41 has now passed the Legislature; next, it will move to Gov. Dunleavy’s desk for signing.

This bill would allow for select non-profit organizations to carry out restoration and enhancement projects for specific shellfish species like king crab, sea cucumbers, abalone, and razor clams. Organizations would utilize hatcheries to raise then release shellfish into Alaskan seas in an effort to support and seed commercial fishing in the region.

“HB 41 plays a key role in the building blocks to make mariculture a growing and significant part of the overall Alaska fisheries portfolio,” said Dan Ortiz, an independent Alaska representative who originally presented the bill in February, 2021.
