Study Finds Growing Potential for Toxic Algal Blooms in the Alaskan Arctic

October 6, 2021 — Changes in the northern Alaskan Arctic ocean environment have reached a point at which a previously rare phenomenon—widespread blooms of toxic algae—could become more commonplace. These blooms potentially threaten a wide range of marine wildlife and the people who rely on local marine resources for food. That is the conclusion of a new study about harmful algal blooms of the toxic algae Alexandrium catenella published in the journal Proceedings of the National Academy of Science. Microscopic algae in the ocean are most often beneficial and serve as the base of the marine food web. However, some species produce potent neurotoxins that can directly and indirectly affect humans and wildlife.

Dormant Cysts Could Seed a Toxic Bloom

The study was led by scientists at the Woods Hole Oceanographic Institution (WHOI) in collaboration with colleagues from NOAA’s Northwest Fisheries Science Center and researchers in the United States, Japan, and China. It looked at samples from seafloor sediments and surface waters collected during 2018 and 2019. Samples were taken in the region extending from the Northern Bering Sea to the Chukchi and Beaufort Seas north of Alaska. The sediment samples allowed the researchers to count and map Alexandrium cysts. The cysts are a seed-like resting stage that lies dormant in the seafloor for much of the year, germinating or hatching only when conditions are suitable. The newly hatched cells swim to the surface and rapidly multiply using the sun’s energy. This produces a “bloom” that can be dangerous due to the family of potent neurotoxins, called saxitoxins, that the adult cells produce.

When the algae are consumed by some fish and all shellfish, those toxins can accumulate to levels that can be dangerous to humans and wildlife. In fish, toxin levels can be high in digestive and excretory organs (e.g., stomach, kidney, liver), but are very low in muscle and roe. Although fish can be potential toxin vectors, the human poisoning syndrome is called paralytic shellfish poisoning. Symptoms range from tingling lips, to respiratory distress, to death. The toxin can also cause illness and death of marine wildlife such as larger fish, marine mammals, and seabirds. This is of particular concern for members of coastal communities, Alaskan Native Villages, and Tribes in northern and western Alaska who rely on a variety of marine resources for food.

ALASKA: With low stocks and closures looming, Bering Sea crab fleet braces for another blow

September 23, 2021 — The Alaska Department of Fish and Game announced earlier this month that all major crab stocks are down. And for the first time in over 25 years, the Bristol Bay red king crab fishery will be closed.

The species is world-renowned and was largely made famous by the popular reality tv show “Deadliest Catch.” In the glory days of king crab fishing, locals describe hundreds of boats rushing into the cold Bering Sea to harvest millions of pounds of the crab worth even more millions of dollars.

The commercial fishery has been around since 1966. In the 55 years since then, there have been just two other closures: once in the 1980s and again in the 1990s.

Now, the Bering Sea crab fleet and fishing communities around the state and the Pacific Northwest are bracing for another blow to their industry and are calling for new conservation efforts.

“It’s big news, and it’s hitting our industry really hard,” said Jamie Goen, executive director for Alaska Bering Sea Crabbers, a trade association representing commercial crab harvesters. “We’re disappointed and deeply concerned.”

Valuable crab populations are in a ‘very scary’ decline in warming Bering Sea

September 22, 2021 — Federal biologist Erin Fedewa boarded a research vessel in June in Dutch Harbor, Alaska, and journeyed to a swath of the Bering Sea that typically yields an abundance of young snow crab in annual surveys.

Not this summer. At this spot, and elsewhere, the sampling nets came up with stunningly few — a more than 99% drop in immature females compared to those found just three years earlier.

Biologists also found significant downturns in the numbers of mature snow crab as they painstakingly sorted through the sea life they hauled up.

“The juveniles obviously were a red flag, but just about every size of snow crab were in dramatic decline,” Fedewa said. “It’s very scary.”

This collapse in the Bering Sea snow crab population comes amid a decade of rapid climatic changes, which have scrambled one of the most productive marine ecosystems on the planet in ways that scientists are just beginning to understand. The changes are forcing them to reconsider how they develop models to forecast harvest seasons.

ALASKA: All major Bering Sea crab stocks are down alarmingly this season, surveys indicate

September 14, 2021 — Alaska’s Bering Sea crabbers are reeling from the devastating news that all major crab stocks are down substantially, based on summer survey results, and the Bristol Bay red king crab fishery will be closed for the first time in over 25 years.

That stock has been on a steady decline for several years, and the 2020 harvest dwindled to just 2.6 million pounds.

Most shocking was the drastic turnaround for snow crab stocks, which in 2018 showed a 60% boost in market-size male crabs (the only ones retained for sale) and nearly the same for females. That year’s survey was documented as “one of the largest snow crab recruitment events biologists have ever seen,” said Bob Foy, director of the North Pacific Fishery Management Council’s Crab Plan Team.

Again in 2019, the “very strong” snow crab biomass was projected at over 610 million pounds, and the catch was set at a conservative 45 million pounds for the 2020 fishery. No Bering Sea crab surveys were done that year due to the COVID pandemic, but the 2021 results indicated the numbers of mature male snow crab had plummeted by 55%.

Winter red king crab fishery in Alaska’s Bering Sea canceled

September 9, 2021 — Low stocks have prompted the U.S. state of Alaska to cancel the red king crab fishery in Alaska’s Bering Sea for winter 2021-2022 season.

After a review of the final bottom-trawl survey by the National Marine Fisheries Service, Alaska Department of Fish and Game (ADFG) ADFG made the announcement Friday, 3 September, saying the stock was “below the regulatory threshold for opening a fishery.” ADFG said more details about the closure will be provided during the TAC meeting in early October.

US House bill would add tribal seats to North Pacific Fisheries Management Council

July 27, 2021 — A key Democrat in the U.S. House introduced a bill Monday to renew the Magnuson Stevens Act. Magnuson Stevens is the primary law that covers fishing in federal waters. Past bills have languished in Congress, in part because many in the industry were generally happy with the law as it is.

But Jared Huffman, D-Calif., included a few provisions in his bill that certain Alaska groups have been requesting for a long time. Huffman chairs the Oceans subcommittee of the House Resources Committee.

The bill emphasizes the need to consider the impacts of climate change on marine resources. It would, for the first time, recognize the importance of subsistence fishing. It would also put two tribal representatives on the North Pacific Fisheries Management Council — the committee responsible for fisheries in the Bering Sea and Gulf of Alaska.

Smaller pollock during Alaska’s season B expected to tighten supplies

July 23, 2021 — Alaska’s Bering Sea pollock B season, which runs from June 10 to October 31, is experiencing strong volumes, but smaller fish sizes are causing a shortage of supply for the pollock fillet market.

This season is an improvement over last year’s B season, when a disappointing slog ended with fishermen leaving part of the total allowable catch in the water. Brent Paine, the executive director of United Catcher Boats, told SeafoodSource that the fish are out there, but they are about half the ideal size.

“The fishing is okay, but the fish are small. The fleet would like to see 700- to 800-gram fish, but what they’re bumping into is a lot of 400-gram fish. They’re smaller than we would like to see,” Paine told SeafoodSource.

During a recent 3-Minute Market Insight, Tradex Foods, a Canadian seafood supplier, warned that the smaller pollock size would strain supply for once-frozen pollock fillets.

“Small-size pollock will ultimately minimize the amount of pollock fillets being produced, especially for anything larger than two to four ounces,” said Tradex’s Kyla Hayward.

Alaska’s Dungeness crab prices double, halibut and blackcod also on the rise

July 16, 2021 — Catches for Dungeness crab at Southeast Alaska are going slow so far for 163 boats, but prices of $4.20 a pound are more than double last year’s. The crab fishery will run through mid-August and reopen in October.

Kodiak crabbers were getting $4.25 for their Dungeness, also more than double.

Norton Sound opened for king crab on June 15 with a 290,000-pound catch limit. Concerns over the depleted stock resulted in no buyers and only one participant who is selling crab locally.

Prince William Sound’s pot shrimp fishery remains open until mid-September with a catch limit of 70,000 pounds. A lingcod fishery opened in the sound on July 1 for a catch of nearly 33,000 pounds.

Ling cod also opened at Cook Inlet with a 52,500-pound catch limit. The Inlet also opened July 1 for rockfish with a 150,000-pound harvest.

New app lets Alaska mariners report real-time changes in the marine ecosystem

July 7, 2021 — Fishermen are the ears and eyes of the marine ecosystem as a changing climate throws our oceans off kilter.

Now a new phone app is making sure their real-life, real-time observations are included in scientific data.

The new Skipper Science smartphone app, released June 18, comes from the Aleut Community of St. Paul Island in the Bering Sea as a way “to elevate the thousands of informal-yet-meaningful environmental observations by fishermen and others into hard numbers for Alaska’s science-based management,” said Lauren Divine, director of ecosystem conservation for St. Paul’s tribal government whose team created and owns the dataset for the app.

“How do we take what has historically been called anecdotal and create some structure around it that is rigorous and has scientific repeatability?” Divine told KCAW in Sitka.

“There is a vast body of deep knowledge that fishermen hold from their experience on the water, indigenous and non-indigenous alike, that they use for decision making and risk evaluation and to execute a likelihood on the water. And we have very much underutilized that knowledge for years, especially here in the North Pacific,” she added in a phone interview.

The free app, which works on or off the internet, is an offshoot of an Indigenous Sentinels Network started 16 years ago at St. Paul Island to monitor wildlife and the environment in the Bering Sea.

To broaden its reach, St. Paul partnered with advocacy group SalmonState’s Salmon Habitat Information Program. Through its surveys and other outreach, SHIP quantifies what’s regarded by scientists as fishermen’s “informal observations” and shares the information with managers and decision makers.
