Summer survey shows strength in Pacific halibut resource

Pacific halibut stock appears to be on an upswing and could result in increased catches for most regions in 2022.

At the interim meeting of the International Pacific Halibut Commission last week, scientists gave an overview of the summer setline survey that targets nearly 2,000 stations over three months. The Pacific resource is modeled as a single stock extending from northern California to the Aleutian Islands and Bering Sea, including all inside waters through British Columbia and Alaska.

The survey showed that coastwide combined numbers per setline increased by 17% from 2020 to 2021, reversing declines over the past four years. The coastwide weights of legal sized halibut (over 32 inches) increased by 4%.

“We’re seeing some new trends this year,” said Ian Stewart, lead scientist for the IPHC which has managed the fishery for the U.S. and Canada since 1923.

“The first is we saw some improving trends from our survey that correspond to a shift both in the fish and in the fishery to younger fish,” he said. “The current stock reflects less productivity from the growth of fish that are already in the stock than from the numbers of fish that are recruiting into the stock,” Stewart explained.

“This is the opposite of what we’ve seen over the past several years. The survey and the fishery have been accessing fish that were growing older. That’s now reversed for this year, reflecting this change from older fish to younger fish moving into the stock,” he said.

The younger fish are from a 2012 class that will be increasingly important to future spawning projections.

“However, we are just now getting a more solid read on the magnitude of this year class and the information in the upcoming years will continue to improve our understanding of just how strong it is,” Stewart said.

Another trend is a shift in halibut distribution back to the Central and Western Gulf of Alaska (Region 3) where most of the stock occurs.

“That stock distribution is more similar to 10 to15 years ago than we’ve seen over the past several years,” Stewart said, adding that the survey showed a 28% increase in halibut abundance in that region.

“We started to see an increase in 2020 but it’s become much more pronounced leading up to a proportion of the stock in Region 3 that is larger than anything we’ve seen in almost a decade, and particularly in the Western Central Gulf,” he said.

Stewart called the 2021 survey “the most effective we have put on the water with the largest information content.”

The coastwide halibut catch limit for 2021 was increased by 6.5% to 39 million pounds for all users. For commercial fishermen in Alaska, the catch limit was set at 19.6 million pounds and all regions except for the Bering Sea saw increased catches.

IPHC data through Nov. 1 show the total take by all users was nearing 38 million pounds. Alaska commercial fishermen had taken 92% of their allotment and recreational catches were estimated at 7.6 million pounds, up by 43% from 2020. Halibut bycatch for this year was at 3.5 million pounds, down 23%.

Final halibut tallies for 2022 will be set at the IPHC annual meeting Jan. 24-28 in Bellevue, Washington.

Bycatch begone

The IPHC sets annual halibut catch limits but federal fishery managers set Alaska’s bycatch caps in waters from three to 200 miles offshore.

Twenty-five Alaska state legislators have submitted a letter to the North Pacific Fishery Management Council asking them to choose an option that will reduce the more than four million pounds of halibut bycatch that can be taken by bottom trawlers in the Bering Sea.

The NPFMC will continue its six years of discussion Dec. 9-13, and take final action on a suite of options, one of which (Alternative 4) would remove the trawl fleet’s fixed cap and have them abide by the same rules as all other users whose catches vary each year depending on the health of the halibut resource.

“It is clear that bycatch is an issue of blatant wanton waste that is impacting our Alaska fisheries like never before! That is the reason I’ve penned this fourth letter to the NPFMC,” said Rep. Sarah Vance, of Homer, who submitted the letter along with Rep. Jonathan Kreiss-Tomkins, of Sitka.

Planet-friendly packaging

OBI Seafoods, which operates 10 processing plants in Alaska, has met its goal for 100% recyclable packaging on all of its nine canned salmon brands.

Starting in January, all cans, lids, labels, holding trays and shrink wrap will be 100% recyclable, and any plastics will contain at least 30% recyclable materials.

“The company is committed to ensuring that its packaging has the lowest possible impact on the planet, and will help their customers reach their sustainability goals,” said CEO Mark Palmer.

The move also means OBI’s canned products are exempt from a new overseas tax in the U.K. on single-use plastics that goes into effect in April.

Meanwhile, packaging made from chitosan, that multi-use biopolymer found in crab shells, has caught the eye of investors.

Cruz Foam, a California-based packaging company, has attracted $2.5 million in seed money to begin producing fully compostable packages to replace petroleum-based Styrofoam at a similar price.

The crab shell-based material provides the same strength and protective properties but features a nearly 98% average bio-breakdown with no adverse effects to the soil, the company said in a press release.

Cruz Foam said that they are taking on plastic pollution “at the root” by inventing a versatile, Earth-compatible product that requires no recycling and “will help set the standard for the future of packaging and sustainable materials.”

The crab shells come from Alaska fisheries and are provided by Tidal Vision, said Tidal CEO Craig Kasberg.
