Among butter clams, which pose toxin dangers to Alaska harvesters, size matters, study indicates • Alaska Beacon
Butter clams, important to many Alaskans’ diets, are notorious for being sources of the toxin that causes sometimes-deadly paralytic shellfish poisoning.
Now a new study is providing information that might help people harvest the clams more safely and monitor the toxin levels more effectively.
The study, led by University of Alaska Southeast researchers, found that the meat in larger butter clams have higher concentrations of the algal toxin that causes PSP, than does the meat in smaller clams.
“If you take 5 grams of tissue from a small clam and then 5 grams of tissue from a larger clam, our study suggested that (in) that larger clam, those 5 grams would actually have more toxins — significantly more toxins — than the 5 grams from that smaller clam,” said lead author John Harley, a research assistant professor at UAS’ Alaska Coastal Rainforest Center.
Partners in the study were the Sitka Tribe of Alaska, which operates one of only two laboratories in the state that test shellfish for algal toxins, and with other organizations.
It is one of the few studies to examine how toxin levels differ between individual clams, Harley said.
The findings came from tests of clams collected from beaches near Juneau on five specific days between mid-June and mid-August of 2022.
The 70 clams collected, which were of varying sizes, yielded a median level of saxitoxins of 83 micrograms per gram, just above the 80-microgram limit. Toxin concentrations differed from clam to clam, ranging from so low that they were at about the threshold for detection to close to 1,100 micrograms per gram.
And there was a decided pattern: Toxin concentrations “were significantly positively correlated with butter clam size,” the study said.
Among the tested clams in the top 25% size, 81% had concentrations above the regulatory threshold, while among the quartile with the smallest size, only 19% came in at above the threshold.
The typical butter clam has a shell that is about 3 inches wide and up to 5 inches in length; clams in the study ranged in shell width from less than 1.5 inches to more than 4 inches. The mass of meat inside the shells of tested clams ranged from 3.87 grams to 110 grams, the study said.
The detections of toxins were in spite of the lack of significant algal blooms in the summer of 2022 – making that year an anomaly in recent years.
In sharp contrast, the summer of 2019 — a record-warm summer for Alaska — was marked by several severe harmful algal blooms. Near Juneau, toxin concentrations in blue mussels, another commonly consumed shellfish, were documented at over 11,000 micrograms per gram, and the toxins killed numerous fish-eating Arctic terns in a nesting colony in the area.
Just why the butter clams tested for the new study showed concentrations of toxins in a low-bloom year is a question for further review.
Butter clams are known to pose special risks because they retain their algal toxins much longer than do other toxin-affected shellfish. Like other species, butter clams do detoxify over time, but they do so much more slowly, Harley said. The clams in the study were all at least a few years old, and there are some possible explanations for why they still retained toxins in the summer of 2022, he said.
“Maybe these larger clams, because they’ve been consistently exposed to harmful algal blooms several years in a row, maybe they just haven’t had a chance to detoxify particularly well,” he said.
The unusual conditions in the summer of 2022 mean that the results of this study may not be the same as those that would happen in a summer with a more normal level of harmful algal blooms, he said. “It still remains to be seen if this relationship between size and toxin is consistent over different time periods and different sample sites and different bloom conditions,” he said.
Research is continuing, currently with clams collected in 2023, he said. That was a more typical year, with several summer algal blooms.
The algal toxin risks in Alaska are so widespread that experts have coined a slogan that reminds harvesters to send samples off for laboratory testing before eating freshly dug clams and similar shellfish: “Harvest and Hold.”
Harley said the fact that there are toxins in clams even when an active bloom is not present “is a very real concern” for those who have depended on harvest. The Southeast Alaska Tribal Ocean Research Network, known as SEATOR, has been monitoring shellfish in winter and other times beyond the usual months of algal blooms, he noted.
That monitoring has turned up cases of toxin-bearing shellfish well outside of the normal summer seasons. Just Tuesday, SEATOR issued an advisory about butter clams at Hydaburg, collected on Saturday, that tested above the regulatory limit for safe consumption.
GET THE MORNING HEADLINES.
Two US soldiers were wounded by a brown bear during a training exercise in Alaska on Thursday, the US Army stated.
Anchorage Daily News reported that the soldiers were from the 11th Airborne Division, and that the exercise had been a “land navigation training event” near Joint Base Elmendorf-Richardson.
State wildlife officials said that the bear attack seemed to be a defensive one, from a bear which had recently emerged from its den. Staff members from the Alaska Department of Fish and Game collected evidence at the scene in an attempt to learn more about the bear, such as its species and gender.
“The incident is currently under investigation, and we are working closely with installation authorities and local wildlife officials to gather all relevant information and ensure the safety of all personnel in the area,” the 11th Airborne Division said in a statement, reported ABC News.
ABC News also cited an 11th Airborne Division spokesperson, Lt.-Col. Jo Nederhoed, who said that the two soldiers had been seriously wounded, but were receiving care at a hospital in Anchorage, and had shown improvement by Saturday morning.
“We hope both individuals have a full and quick recovery, and our thoughts are with them during this time,” Fish and Game Regional Supervisor Cyndi Wardlow said in a statement reported by Anchorage Daily News. “In this case, having bear spray with them in the field may have saved their lives.”
Both of the soldiers reportedly had and used bear spray during the attack.
The bear’s condition and whereabouts are currently unknown.
Up, up and away … that’s where most travel prices are going.
It’s true. Not only are our nation’s geopolitical thrusts in the Mideast affecting the cost of your fill-ups, every component of your trip from airfares to car rentals and hotel stays are subject to price hikes.
Imagine filling up a jetliner with jet fuel that’s doubled in price. It’s enough to melt your credit card, regardless of the number of points you get for every dollar spent!
Because the price of oil affects everything, higher prices are eating away at your travel budget in many ways.
Bag fees
There’s lots of press on this. All airlines are increasing their checked-bag fees because of the jump in fuel prices.
Back in 2009, Alaska Airlines instituted a $15 fee for the first checked bag and $25 for the second bag. At the time, there was no charge for the first bag and a second bag was $25.
Last week, Alaska Airlines, along with other major airlines, increased its fees to $45 for the first checked bag and $55 for the second bag. Delta Air Lines charges the same.
Even if the cost of oil comes down, I don’t expect bag fees will ever be reduced.
Travelers who live in Alaska are somewhat insulated from the new hikes because both Delta and Alaska Airlines offer two free checked bags, with conditions:
1. Alaska offers two free checked bags for travelers flying to or from Alaska who are enrolled in Club 49. This does not affect other flights on Alaska. Separately, ATMOS credit card holders can get a free checked bag. Also, elite members of the ATMOS scheme get one or two free checked bags systemwide.
2. Delta offers two free checked bags for travelers flying to or from Alaska who are SkyMiles members who live in Alaska. Again, this does not apply to other Delta flights. Separately, Delta American Express cardholders can get a free checked bag.
3. Elite-level travelers with the oneworld airline cartel, including Alaska Airlines, can get one or two checked bags on American, British Airways, Japan Airlines, Qantas or other oneworld carriers.

Main Cabin vs. Basic Economy
The spread between the lowest available price, Basic Economy, and a more flexible ticket, Main Cabin, has increased. While the difference used to be $20-$30 each way when the Basic Economy scheme was introduced in 2018, the round-trip upcharge now can exceed $100.
For example, the lowest Basic fare to Portland is $337 round-trip on Alaska Airlines. The upcharge to Main Cabin, with full loyalty points, pre-assigned seats and more flexibility on changes and cancellations, is $447, a 33% upcharge.
This trend is not specifically attributable to the new Iran War. It’s just a cost that continues to rise.
New fees
I’m impressed at the creativity of airline people who dream up new fees. Here are some of my favorites from Alaska Airlines:
1. Phone reservations: $15
2. Partner award booking fee: $12.50
3. Pet travel fee: $100 in the cabin, $200 in the baggage compartment with a kennel
4. Left on board item return fee: $20
On Condor Airlines, operating the only nonstop service from Anchorage to Europe, travelers can choose from four different bundles in economy class. The least-expensive, Economy Zero, from $840 round-trip, features fees for travelers:
1. Carry-on bag fee, up to 8kg: $35; a small bag like a purse always is included for free
2. Checked bag: $75
3. Airport check-in: $30
All three of these fees are included in the next-highest fare bucket, Economy Classic, from $900 round-trip. It’s cheaper to buy the bundle than it is to buy the components a la carte. Seat assignments are additional, from $25 for economy.
Airfares on the rise
There are a few good deals available for travel to select West Coast/Intermountain destinations in May, including:
1. Anchorage-San Francisco on Alaska Airlines, from $307 round-trip. Fly May 15-28 only. Add $90 round-trip for Main cabin.
2. Anchorage-Los Angeles on Alaska Airlines, from $317 round-trip. May 15-25 only. Add $90 round-trip for Main.
3. Anchorage-Phoenix on United, Delta or Alaska, from $267-$287 round-trip. Fly May 8-June 9 only. Add $90-$100 for Main.
4. Anchorage-Denver $357 round-trip on Delta. Fly May 8-June 9 only. Add $90 round-trip for Main.
For travel to other destinations, or later in the summer, be prepared to pay more.
Flying to Hawaii? Alaska Air’s nonstop prices out at $706 round-trip between May 30 and June 6. Add $110 round-trip for Main.
Nonstop flights from Anchorage to Salt Lake City start at $669 round-trip with Delta on May 17. That’s $100 more than the cost for the same flights last month. Add $90 more for Main.
Hotel costs continue to rise, accompanied by pesky resort fees.
The Outrigger on the Beach in Waikiki is a very nice beachfront hotel. It’s not plush, or the nicest property. But it’s solid. The cost is $334 per night.
But there’s more: a $50 per night resort fee, plus a variety of taxes and charges, totaling $112.55 per night.
Down in Seattle, the Sound Hotel in the Belltown neighborhood is marketed by Hilton. The discounted rate for “Honors” members — it’s free to join — is $313.34 per night for a king room in late May. Taxes and fees add an extra $56.40 per night.
There’s no appreciable bump yet for hotel rates as a result of the oil price surge. Yet. But if these hotel rates seem high, they’re in line with hotel rates in Anchorage this summer. At the Sheraton in Anchorage in June, it’s $450 per night, plus $54 in taxes and fees, when booked at Expedia.
Car rentals are not cheap
My go-to site for car rentals is the Costco site, which compares major brands and automatically includes Costco discounts.
In Las Vegas, for a one-day rental in May, Budget charges $67 per day, which includes taxes and fees of $22.77. In Anchorage, the same kind of car, medium SUV, costs $92.97 with Alamo.
The biggest differences so far in car rental rates seems to be the bill you’ll pay when you fill up the tank before returning. There’s no appreciable jump in prices because of the new war.
When it comes to making travel arrangements for the spring and summer, it’s more risky making completely non-refundable arrangements.
I made the decision to purchase most of my summer travel plans in advance, but only after determining I would not need to change the dates. Particularly with airline tickets, it’s expensive to change your dates.
There’s lots of uncertainty regarding travel arrangements, particularly international travel. As fuel prices go up due to oil shortages, travel companies will look for ways to recoup the increased costs. In most cases, those higher costs will be borne by travelers.
ANCHORAGE, Alaska (KTUU) – The reopening of the Strait of Hormuz has led to a decrease in oil prices nationally, but Alaska’s senior senator said the state faces a different situation that could threaten rural communities.
“If you can’t produce power because you don’t have the diesel or you just can’t pay the prices, your little communities can collapse,” Sen. Lisa Murkowski, R-Alaska, said at a Friday press conference at the Arctic Encounter Summit in Anchorage.
The price of oil has been a double-edged sword for Alaska. On one hand, the increased price of North Slope oil brings more revenue to the state, but consumer prices can also rise.
North Slope oil prices were $106.36 a barrel on Thursday.
“This is a very precarious time,” Murkowski said. “Our state has enjoyed a bounty because we have benefited from the higher prices of oil that goes into our treasury, but it’s the Alaskans in … the off-road communities that are threatened to be hit most hard.”
