Shrinking Salmon in Alaska Will Hit the Global Fish Trade

May 3, 2021 — Climate change and other threats to one of the world’s last bastions of wild salmon are already roiling the food supply chain and could alter U.S. export sales of the widely sought-after fish.

About 40% of the world’s wild salmon comes from Alaska, where fishermen are seeing fish size shrink. Scientists are still delving into the precise causes — it’s complicated because there are five different species of Pacific salmon in North America — but the consensus is that climate change is a main culprit.

The size conundrum could end up disrupting global trade flows. American exporters may soon find they’re selling more to Japan, which typically favors smaller fish. Meanwhile, European markets, especially those with heavy demand for smoked salmon, prefer bigger products, according to Elizabeth Herendeen, marketplace manager at Alaska-based Salmon State, which advocates for the protection of Pacific salmon.

It’s the latest example of how climate change is changing how food is produced and where it gets shipped. Rapidly warming temperatures are forcing some lobster boats to move further offshore, and hotter Midwest summers are a threat to yields. Agriculture futures have surged recently as bad weather makes it harder to grow crops at a time when food inflation is already on the rise.

The salmon you buy in the future may be farmed on land

April 29, 2021 — In a series of indoor tanks 40 miles south west of Miami, Florida, five million fish are swimming in circles a very long way from home.

The fish in question are Atlantic salmon, which are far more typically found in the cold waters of Norway’s fjords or Scotland’s lochs.

As the species is not native to Florida, and would be unable to cope with the state’s tropical heat, the water tanks are kept well chilled, and housed in a vast, air-conditioned and heavily insulated warehouse-like building.

The facility, called the Bluehouse, opened its first phase last year, and intends to be the world’s largest land-based fish farm.

Targeting an initial production of 9,500 metric tonnes of fish per year, its owner – Atlantic Sapphire – plans to increase that to 222,000 tonnes by 2031, enough to provide 41% of current US annual salmon consumption, or a billion meals.

The company is at the forefront of a growing movement in Europe, Asia and the US towards land-based, indoor aquaculture. But what could it mean for traditional sea-based salmon farms, and most importantly – what about the welfare of the fish?

ALASKA: Fundraising campaign aims at testing Anchorage salmon streams for toxin traced to tires

April 27, 2021 — Are toxins from road runoff a threat to salmon in Anchorage’s most popular fishing streams? A Go Fund Me campaign has been launched so Alaskans can chip in to find out.

The push stems from an organic compound in tires called quinone that was newly identified by researchers at the University of Washington, said Birgit Hagedorn, a geochemist and longtime board member of the Anchorage Waterways Council.

“The little flakes that rub off of tires, especially larger truck tires, can be transported into the streams via stormwater. And they leach out the compound that they discovered was highly toxic to salmon. They were specifically looking at coho salmon,” she explained.

Hagedorn hopes to raise $5,500 to test the urban waters that run off the Seward and Glenn highways into Ship Creek and Campbell Creek. The Ship Creek salmon sport fishery is the region’s most popular and successful, with anglers targeting stocked chinook and coho salmon. Other stocked coho fisheries have been established in Campbell and Bird creeks, according to the Alaska Department of Fish and Game.

StarKist says all its salmon and tuna now sustainably-sourced

April 26, 2021 — Starkist is now sourcing all of its tuna and salmon from sustainable sources.

The Pittsburgh, Pennsylvania, U.S.A.-based company is now sourcing 100 percent of its tuna and salmon from suppliers that meet the Marine Stewardship Council (MSC) standard for sustainable fishing or are working toward certification, including those participating in a comprehensive fishery improvement project (FIP), the tuna supplier said in a press release.

Trial shows Calysta’s FeedKind can replace 30 percent of fishmeal in yellowtail feed

April 26, 2021 — A trial at Japan’s Kindai University has shown that Menlo Park, California-based Calysta Inc.’s FeedKind bacterial protein meal (BPM) can replace up to 30 percent of fishmeal protein – or up to 20 percent of total feed – in the diet of yellowtail without any impact on growth rate, digestibility, daily feeding rate, or feed efficiency.

The paper, “Methanotroph (Methylococcus capsulatus, Bath) bacteria meal as an alternative protein source for Japanese yellowtail, Seriola quinqueradiata,” written by a group of researchers led by Amal Biswas, was published in the journal Aquaculture. It details two trials – one of 1,500 yellowtail fish, and the second of 800 – analyzed over an eight-week period. In both cases, a control diet was used alongside increasing concentrations of FeedKind. Fish survivability was 100 percent across all tests, with no significant difference between the control diets and the 25 percent inclusion rate across both trial groups.

ALASKA: New report estimates at least $5M cost to replace subsistence salmon with other protein sources in Bristol Bay

April 23, 2021 — A third of the state’s subsistence salmon harvest was caught in Bristol Bay in 2017, according to a new report from the McKinley Research Group. The subsistence economy is critical to Bristol Bay’s culture, and it’s the oldest and most continuous use of salmon.

The report, “The Economic Benefits of Bristol Bay”, attempts to quantify what it would cost to replace subsistence salmon with other protein sources from stores in the region.

Bristol Bay subsistence fishers caught over 500,000 pounds of salmon in 2017, according to the latest data available. The research group estimates that it would cost $5-$10 million to replace that catch with other sources of protein. Rebecca Braun is one of the researchers who worked on the report.

“Because the world speaks in dollars, we tried to translate the subsistence harvest into dollars,” Braun said. “And it’s kind of an inherently impossible exercise because subsistence values goes beyond economics.”

Continuing Species in the Spotlight Initiative Empowers NOAA Fisheries’ Endangered Species Conservation Efforts

April 22, 2021 — The following was released by NOAA Fisheries:

NOAA Fisheries has released nine new Species in the Spotlight Priority Action Plans. These plans highlight the most vital actions that NOAA Fisheries and our partners can take to reverse the declining populations of nine endangered marine species that are most at risk of extinction. Building on the successes of the past five years, NOAA Fisheries is renewing the initiative through 2025 to sustain momentum toward recovery.

The Species in the Spotlight initiative, launched in 2015, focuses time, energy, and resources on the most imperiled marine species. It motivates partners and community members to join the effort to save these species from extinction. The nine species are all listed as endangered under the Endangered Species Act:

These species are at high risk of extinction in the near future because of a rapid population decline or habitat destruction. They face human-caused threats such as construction, development, or other economic activity.

“The Species in the Spotlight initiative is a critical effort by NOAA Fisheries and our partners to leverage our resources and make the greatest impact to reverse the decline of these endangered species. I’m pleased to build upon our successful efforts to date with the renewal of these Species in the Spotlight Priority Action Plans,” says Sam Rauch, Deputy Assistant Administrator for NOAA Fisheries Regulatory Programs.

ALASKA: Commercial and subsistence harvesters speak out against trawler bycatch of Chinook salmon

April 22, 2021 — Alaska’s commercial fishermen have been speaking out against big trawlers for years, complaining that the large vessels in federal waters are scooping up mature and juvenile fish. The regional council that manages federal fisheries recently heard from hundreds concerned about the number of salmon and other species that end up as bycatch in trawl nets.

For Alaska’s troll fleet, king salmon is their money fish. In state waters, small crews on these 40 to 50-foot boats — or even small skiffs — will catch a fish at a time, and it’s worth it: Chinook salmon can fetch $6 a pound from a processor.

But there’s another big-money fish in Alaska: Pollock. It’s the white fish found in a McDonald’s Filet-O-Fish® or an imitation crab stick. And the factory trawlers that ply the Bering Sea and Gulf of Alaska in search of pollock and other groundfish scoop up Chinook salmon and other species in their wide nets.

Federal fisheries data show trawlers in the North Pacific took about a tenth of the Chinook — or king salmon — caught by Alaska’s commercial salmon fleet last year. And those numbers are tracking the same this year. But none of that catch happens on purpose.

Preliminary ADF&G data show about 263,000 kings were commercially harvested last year statewide. As of last week (April 15), bycatch in the Bering Sea and Gulf of Alaska areas for 2021 was around 16,000 fish, over six percent of last year’s statewide commercial harvest. Last year’s trawler bycatch was 26,000 kings, or about a tenth of the 2020 commercial Chinook harvest in-state.
