‘Frankenfish’ is coming, but opponents vow to fight on

March 18, 2019 — If all goes as planned, a Massachusetts biotechnology company will soon begin importing salmon eggs from a Canadian hatchery to its plant in Indiana, where they’ll grow into the first genetically modified salmon ever produced in the United States.

AquaBounty Technologies Inc. won approval for its long-delayed plan last week when federal regulators lifted an importation ban that had prohibited the eggs from entering the country.

But opponents, who deride the new salmon as “Frankenfish,” say the fight will go on and that they’ll ultimately block the company, either in the courts or Congress.

Critics fear the fish might escape and damage wild salmon, and they’re particularly angry that the federal government plans to allow the genetically engineered salmon to be made and sold in the United States without clearly marked labels. The fish’s proponents have said those critics are just being protective of the existing industry’s market share.

Taking the sea out of seafood

March 15, 2019 — Land-based aquaculture can sound like a mirage — shrimp farms in the desert, salmon swimming “upstream” in an alpine village tank, tilapia swishing over the plains. And for a long time, ample production of sea delicacies in recirculating aquaculture systems (RAS) has been more dream than reality. Yet the technology and its innovators steadily have gained momentum and finally may be hitting their tipping point.

The allure of fish grown on land is easy to understand: Like all aquaculture, it reduces demand for wild fish, but unlike with sea-based pens, closed-loop RAS farms (PDF) run no risk of fish escaping to dilute the native gene pool, spread diseases or discharge waste and antibiotics into the wild. RAS farmers have near-full control over growing conditions, so they can optimize for growth and quality. And with its amenability to unlikely locations, RAS can sit near major consumer markets, providing fresh local seafood even when the shore is hundreds of miles away.

So why aren’t we eating it already? RAS entrepreneurs face three big challenges: energy; contamination risks; and money. Mimicking a natural system within strictly regulated parameters is an energy-intensive endeavor, and sustainability (not to mention costs) demands locating RAS facilities next to cheap, abundant energy sources. A pathogen let loose in a closed system can be a disaster, so RAS farmers have to be extra scrupulous about avoiding contamination.

Money may be the biggest hurdle: RAS operations need high volumes and relatively long ramp-ups to reach profitability, and the pile of patient capital needed to build and grow large, high-tech facilities can be as elusive as Moby Dick.

Cardiorespiratory fitness of farmed Atlantic salmon unaffected by virus

March 14, 2019 –The respiratory systems of Atlantic salmon function normally even when carrying large loads of piscine orthoreovirus (PRV), new UBC research has found.

“We didn’t find significant harm to the fish’s respiratory physiology despite the virus replicating to a load equal to, if not higher, than those seen naturally in wild or farmed fish” said Yangfan Zhang, a Ph.D. student in UBC’s faculty of land and food systems and lead author of the study published today in Frontiers in Physiology.

PRV is present in nearly all farmed Atlantic salmon on Canada’s west coast, and various strains of PRV have been detected in many salmonid species around the world. Consequently, the results are a positive step in reducing the uncertainty about the potential of infected farmed Atlantic salmon in marine pens to negatively impact migrating wild Pacific salmon.

Fisheries Managers Face Mixed Forecast For Northwest Salmon, Concerns Over Endangered Orca

March 12, 2019 — About this time every year, the Pacific Northwest gets a report card from the natural world. It comes in the form of salmon run forecasts and gives us an indication of how healthy the Pacific Ocean and our rivers and streams are.

The grades are in, and here’s what you need to know about our scores.

How’d we do this year?

It’s definitely looking like we’re in for a “there’s room for improvement” kind of year.

Every spring, a group called the Pacific Fishery Management Council gets together and look at the salmon forecasts from the Puget Sound all the way down to the Sacramento River in California. They use this data to decide at a week-long meeting in April what overall catch limits will be. This catch allowance is then split between commercial, recreational and tribal fishermen in the Pacific Northwest. The goal is to make sure we don’t catch more salmon than the numbers can actually support.

Feds inch closer to approving Alaska mining project seen as a threat to Pacific Northwest

March 11, 2019 — Over the past several decades, fishermen, business owners, Alaska Native organizations and environmental groups have protested a proposed open-pit copper and gold mine at the headwaters of Bristol Bay — a pristine salmon habitat.

Now the federal government is inching toward approving the mining project.

Nestled in southwest Alaska, Bristol Bay is home to the world’s largest wild salmon run. The watershed supports a teeming ecosystem of eagles, grizzlies and beluga whales.

It’s also an economic engine for the Pacific Northwest. Each year, the fishery contributes thousands of seasonal fishing and processing jobs and millions of dollars in economic activity to Washington, Oregon, and California, according to the University of Alaska Institute of Social and Economic Research.

Bristol Bay is where the Pebble Limited Partnership, the company developing the mine, plans to build a 10.7-square-mile open-pit mine to dig up copper, gold, molybdenum, and other minerals. The mine would require new infrastructure, including roads, a port and a 188-mile-long natural gas pipeline.

Trump Administration Shortcuts Science To Give California Farmers More Water

March 11, 2019 –When then-candidate Donald Trump swung through California in 2016, he promised Central Valley farmers he would send more water their way. Allocating water is always a fraught issue in a state plagued by drought, and where water is pumped hundreds of miles to make possible the country’s biggest agricultural economy.

Now, President Trump is following through on his promise by speeding up a key decision about the state’s water supply. Critics say that acceleration threatens the integrity of the science behind the decision, and cuts the public out of the process. At stake is irrigation for millions of acres of farmland, drinking water for two-thirds of Californians from Silicon Valley to San Diego, and the fate of endangered salmon and other fish.

Farmers will only get more water after federal biologists complete an intricate scientific analysis on how it would affect endangered species. But an investigation by KQED finds that analysis will be done under unprecedented time pressure, with less transparency, less outside scientific scrutiny, and without, say federal scientists, the resources to do it properly.

“It’s a very aggressive schedule,” says a former federal biologist familiar with the matter who did not want to be named for fear of retribution. “And I think it runs the risk of forcing them to make dangerous shortcuts in the scientific analysis that the decisions demand.”

Maine can have both environmental stewardship and aquaculture innovation

March 11, 2019 — There is a 90 percent deficit in fresh seafood trade in the U.S. A large amount of the fresh salmon consumed in the U.S. is flown in from Europe, Chile, and New Zealand, leaving a considerable carbon footprint. Along with an expected 7 to 8 percent annual growth in seafood consumption, there is a strong incentive for creating new, sustainable food systems in the U.S.

While the demand-supply gap keeps growing, there is no growth in sight from wild catch fisheries or net pen operations. Thus, solutions must take a new approach to fish farming and be sustainable. This is where local, land-based aquaculture comes into the picture.

Nordic Aquafarms was started in Norway with a mission to create a more environmentally sustainable way of producing fish — a solution for the future. Nordic Aquafarms is an international front-runner in the land-based fish farming industry. Land-based facilities are indoor production facilities where fish are raised to harvest size in a series of independent tank systems. It is not possible for the fish to escape from our facility, while other potentially harmful effects on wild salmon populations are eliminated.

Scientists see improved ocean conditions for young salmon

March 11, 2019 — Ocean conditions are improving for salmon entering the ocean this year, several years after The Blob, an unusually warm water event that began forming in 2014, scientists announced Friday.

Research surveys in 2018 confirmed tiny animals that stoke the food chain were nice and fatty. Anchovies, an important forage fish, were increasing in number. Sea lion pups were numerous and growing well, and fish-eating sea birds going strong.

However, subsurface sea temperatures were still warmer than average in some areas. Pyrosomes, a warm-water animal that is not supposed to be in Northwest waters, were still numerous.

Forecasts for chinook salmon in 2019 also were for below-average salmon returns to the Columbia River. Extensive ocean acidification and poorly oxygenated waters off both Washington and Oregon also were predicted for this year.

US government seeking to buy large quantity of wild salmon

March 6, 2019 — The United States Department of Agriculture is asking for bids on 324,000 pounds of frozen wild salmon fillets.

Bids on the salmon, which will be used for the National School Lunch Program and other Federal Food and Nutrition Assistance Programs, must be made by 29 March.

The USDA wants the frozen salmon fillets delivered in cases of 40, one-pound packages.

CALIFORNIA: Fishermen cautiously optimistic for strong salmon season

March 4, 2019 — After three difficult years when Chinook salmon population numbers were down and fishing opportunities were limited, commercial fishermen are hoping that the upcoming season will be better.

“What we’re seeing is a better forecast of salmon in the ocean this year than we saw last year,” said Harry Morse, public information officer for the California Department of Fish and Wildlife, following a meeting with about 85 commercial and recreational anglers on Wednesday in Santa Rosa. “We’re cautiously optimistic.”

Commercial anglers who traditionally rely on salmon fishing for their livelihood have contended with three curtailed seasons in a row, a ripple effect of the drought that lasted from 2013 to 2016. Diners and restaurants have also experienced the aftereffects in terms of high prices and scarce supplies of salmon, turning what was once a spring and summer staple into a luxury item.

What’s different for the coming season, which is scheduled to start in May, is that there is a much larger estimated number of salmon in the ocean, meaning that catch limits will likely be somewhat looser when they are announced in April.

“It’s been a tough couple years for commercial fishermen,” said Jimmy Phillips, 37, of Half Moon Bay, who attended the meeting in Santa Rosa. A commercial fisherman for 19 years, he was struck by the fact that sports fishermen, who get a longer season and are allowed to keep smaller fish, were allowed to catch more fish than the commercial anglers. “We just want to see some fairness. We as a whole feel like it really has not been fair.”
