Aquaculture Rule Changes up for Public Comment in Maine

January 14, 2019 — Maine fisheries managers are looking to make a number of changes to aquaculture rules in the state, and are asking for feedback from the industry and the public about the potential changes.

The Maine Department of Marine Resources is considering a proposal that would make changes to the leasing procedures it uses for farmers of seafood. The new rules would also clarify that an emergency lease could be used when the safety of consumers is threatened, and they would establish minimum lease maintenance standards.

Oregon begins killing sea lions after relocation fails

January 11, 2019 — Oregon wildlife officials have started killing California sea lions that threaten a fragile and unique type of trout in the Willamette River, a body of water that’s miles inland from the coastal areas where the massive carnivorous aquatic mammals usually congregate to feed.

The state Department of Fish and Wildlife obtained a federal permit in November to kill up to 93 California sea lions annually below Willamette Falls south of Portland, Oregon, to protect the winter run of the fish that begin life as rainbow trout but become steelhead when they travel to the ocean.

As of last week, wildlife managers have killed three of the animals using traps they used last year to relocate the sea lions, said Bryan Wright, project manager for the Oregon Department of Fish and Wildlife’s marine resources program.

The adult male sea lions, which weigh nearly 1,000 pounds (454 kilograms) each, have learned that they can loiter under the falls and snack on the vulnerable steelhead as the fish power their way upriver to the streams where they hatched.

ALASKA: Cook Inlet sockeye forecast improves; kings closed in North

January 10, 2019 — After two disappointing sockeye seasons in a row, the 2019 season may look up for Upper Cook Inlet commercial fishermen.

The Alaska Department of Fish and Game’s sockeye salmon forecast, published Jan. 4, predicts a total run of 6 million sockeye to Upper Cook Inlet stream systems, with an expected commercial harvest of 3 million and 1 million for sportfishing and subsistence harvest.

If the forecast proves true, the run will be nearly double the 2018 run of 3.1 million.

The Kenai River, the largest sockeye-producing river in the region, is projected to receive a run of about 3.8 million sockeye, the majority of which are the 1.3 age class (one year in freshwater, three years in saltwater).

The Kasilof River, the second-largest producer, is projected to see about 873,000 sockeye come back, with a slight majority in the 1.3 age class.

The Kenai’s forecast is greater than its 20-year average of 3.5 million, while the Kasilof’s is behind its 20-year average of 979,000 fish.

New Pacific Salmon Treaty cuts chinook catch

January 9, 2019 — The new Pacific Salmon Treaty went into effect on the first of the year after the treaty’s last 10-year iteration expired on its own terms on 31 December.

The Pacific Salmon Treaty is renegotiated every decade between the United States and Canada to govern salmon catch, research, and enhancement in Alaska, Oregon, Washington, and British Columbia.

The Alaska Department of Fish and Game made public last week the sections of the treaty that will directly affect Alaskan salmon fisheries, which deal with Transboundary Rivers, Northern British Columbia and Southeastern Alaska, and Chinook salmon.

In an attempt to battle a dramatic multi-year drop in Chinook stocks off of the Pacific coast, the countries agreed to cut their catch of Chinook salmon, with a reduction of up to 12.5 percent in Canada and up to 7.5 percent in the United States.

Some in the industry are not pleased with the new treaty.

Japanese seafood giants invest in land-based aquaculture

January 8, 2019 — Two of Japan’s largest seafood companies, Maruha Nichiro and Nippon Suisan Kaisha, or Nissui, soon expect to begin commercial shipments of fish farmed in land-based facilities in Japan, reports Nikkei.

At a land-based salmon farm in the town of Yuza, in the northwestern prefecture of Yamagata, Maruha Nichiro farms a variety of salmon known locally as sakuramasu. Maruha, which developed the system with valve maker Kitz, expects to ship its first batch of sakuramasu soon.

Maruha president Shigeru Ito said he aims to market the fish as a Japanese product in a country that relies on imports for 90% of its salmon consumption.

Meanwhile, Nissui plans to begin inland farming of mackerel next year, according to Nikkei, aiming to become the first company in Japan to sell farmed mackerel commercially. The key goal of the project is to cut costs by teaming up with a business in another industry that has a water treatment technology.

Scientists in Alaska are tracking fish by DNA

January 7, 2019 — Have you ever thought about testing your DNA through companies like 23andMe or Ancestry.com?

Geneticists here in Alaska are using that same technology on fish, but they’re not looking for their ancestors. Instead, they’re using it to trace back where marine species are born and where they’re caught.

The administrative headquarters for the Alaska Department of Fish and Game off of Raspberry Road in Anchorage is best known as an office building, but tucked inside is one of the most advanced genetics labs on the Pacific Rim.

“We have one instrument in particular that is the same instrument that is used by 23andMe and Ancestry.com,” said lab supervisor Heather Hoyt.

But unlike those organizations, its not human DNA that Hoyt and her team are testing. They’re focused mainly on fish.

ALASKA: Harvesting the haul

January 4, 2018 — After a steep drop in 2016, seafood harvesting employment rebounded in 2017, growing 8.3 percent and hitting a record of 8,509 average monthly jobs in the state of Alaska.

The employment growth was widespread, covering most species and regions, which was a departure from previous years when certain fisheries’ or regions’ growth tended to offset losses elsewhere.

The 8.3 percent growth for seafood harvesting in 2017 was the largest in percent terms among Alaska industries. Health care, which has been marked by strong job growth for decades and has been one of the few industries to grow throughout the state recession, grew by just 2.3 percent.

Summer and fall brought impressive growth in harvesting jobs after a weak start to the year. Most of the year’s growth came during the summer. July has always been the seafood harvesting peak, and in 2017 it went up by another 634 jobs, bringing the July total to 24,459.

The biggest jumps came on the edges of the summer, however. June, September, and October each gained more than 1,000 jobs from 2016’s levels. June’s employment grew the most, up 1,877 jobs from June 2016.

The year’s few losses came in the early months. January, February and March levels were all down from the year before. Those months are more important for crab fisheries than other species, which is why crab harvesting was one of the few fisheries that lost jobs in 2017.

Washington taking comment on permits for Atlantic salmon fish farms

January 4, 2019 — The state Department of Ecology is taking comment now on permits for four Cooke Aquaculture Atlantic salmon farms — three in Kitsap County and one in Skagit Bay.

Farming Atlantic salmon in net pens is officially banned from Puget Sound starting in 2022.

Ecology is using the investigation from the 2017 Cypress Island net pen collapse to mandate more protective permit requirements.

Cooke Aquaculture, the only company farming Atlantic salmon in Washington state, lost its lease in Port Angeles in 2017.

Ecology is accepting comments on the permit through Feb. 25 and will make a final determination after reviewing them.

Why Does Halibut Cost So Much?

January 4, 2019 — Dishes fly across the galley. Water gushes through the scuppers and onto the deck. Five crew members on the 17.5-meter commercial halibut boat Borealis Iwalk like drunkards, holding onto anything stable. “We’re going to get bounced around a bit,” Dave Boyes, the boat’s captain and owner, deadpans.

My day started at first light, about six hours ago, watching the crew let out 2,200 galvanized circle hooks laced with chunks of pollock, squid, and pink salmon to soak across 13 kilometers of ocean bottom. Then, we ate breakfast and rested in cramped, cluttered bunks while the boat bounced on 1.5-meter waves and—below, in the cold unseen depths—the hooks sunk deep into the lips of the predatory halibut.

Now, the crew readies for battle, cinching rubber rain gear and running crude gutting knives across electric sharpeners—a portent of the bloodshed to come. When Boyes toots the boat’s horn, it’s game on.

My love of halibut got me here—in Hecate Strait, off northern British Columbia—as did my disdain for the price. Salmon are held up as the iconic symbol of the Pacific Northwest, but the way I see it, halibut is king, offering superior flavor and texture. When I can afford it, I serve the white fish baked with a glaze of butter, mayonnaise, and whole grain Dijon mustard.

During a summer visit to my local fish shop—Mad Dog Crabs in the Cowichan Valley of Vancouver Island—fresh halibut fillets sold for CAN $6.38 per 100 grams, compared with $5.28 for sablefish and $3.74 for sockeye salmon. “It’s the prime rib of the sea,” explained fishmonger Scott Mahon, who fished commercially for over 20 years. “Better taste, better quality, and better shelf life.” Unlike the farmed salmon industry, halibut aquaculture remains a relatively nascent enterprise and does not offer a less-expensive alternative to consumers.

OSU scientist studies slimy new way to count salmon

January 3, 2019 — Scientists have published a novel method for counting Pacific salmon – analyzing DNA from the slime the fish leave behind in their spawning streams.

The study, funded by The National Geographic Society, is published in the journal Molecular Ecology Resources.

“When we analyzed the environmental DNA sloughed into water from salmon tissues, including mucus and skin cells, we got very accurate counts,” said Taal Levi, an ecologist at Oregon State University and lead author on the study. “This is a major first step for more informed salmon management decisions because it opens up the possibility to affordably monitor many more streams than the few that are currently monitored.”

Pacific salmon are a keystone resource in the Pacific Northwest, with an economic impact of well over $500 million each year in Alaska alone. Currently, spawning salmon are counted at just a few streams due to the reliance on human counters, or in rare cases, sonar. Five species of Pacific salmon – pink, chum, sockeye, coho, and chinook – are distributed through more than 6,000 streams in southeast Alaska alone. More than 1,000 of those streams host spawning salmon.

Salmon are anadromous: They migrate from home streams to the ocean as juveniles, and return a few years later as adults to spawn. Anadromous fish such as salmon provide a straightforward scenario for testing whether environmental DNA (eDNA) can be used to count fish, because large numbers of salmon release their DNA as they pass a fixed sampling point, either as they swim up a river or stream as inbound adults or swim downstream as outbound juveniles.

In many rivers and streams, including the majority of freshwater systems in Alaska, adult salmon returning to spawn are poorly monitored, as are fry and smolt production resulting from spawning salmon.

For the study, researchers collected water samples in 2015 and 2016 near the Auke Creek research weir, nearly 16 kilometers north of Juneau. Weirs consist of a series of closely spaced bars across an entire stream to prevent the passage of salmon, except through a single, narrow gate over which a human observer tallies and identifies salmon as they file through.

The Auke Creek weir, cooperatively operated by the National Marine Fisheries Service, in collaboration with the University of Alaska and the Alaska Department of Fish and Game, is known as one of the most accurate fish counters in the world, Levi said.
