Salmon breakthrough was driven by chance

November 25, 2015 — It was the early 1980s, and a group of Canadian fish farmers was hoping to find a way for salmon to thrive in the region’s frigid waters. So scientists in Newfoundland began experimenting with how to inject them with antifreeze proteins from an eel­-like creature known as ocean pout.

Instead, they found a way to make the fish grow more quickly.

That work, more than 30 years ago, led to the controversial breakthroughs that allowed AquaBounty Technologies, a biotechnology company in Maynard, to produce a rapidly growing salmon, which the Food and Drug Administration last week declared the first genetically altered animal fit for consumption.

“We thought if we can enhance the growth rate, that’s good for the industry, which can get fish to market faster,” said Garth Fletcher, a researcher at Memorial University in Newfoundland, who did the initial experiments that led to the creation of salmon that can grow twice as fast as those in the wild. Fletcher’s technique of inserting growth hormone from Chinook salmon and a “promoter gene” from ocean pout is now considered antiquated technology. But scientists say its commercial application heralds a new era of genetic engineering.  

Federal regulators on Thursday approved a Massachusetts biotechnology company’s bid to modify salmon for human consumption.

Fletcher’s technique of inserting growth hormone from Chinook salmon and a “promoter gene” from ocean pout is now considered antiquated technology. But scientists say its commercial application heralds a new era of genetic engineering.

New techniques have allowed scientists to more precisely alter animal genomes by editing DNA to include or exclude beneficial or harmful traits. Researchers are now experimenting with modifying the genes of chickens so they don’t transfer avian flu, for example. They also want to develop pigs and cattle that are resistant to foot and mouth disease, and goats that produce a higher level of a microbial protein that may help treat diarrhea in people.

Blumenthal wants GMO salmon labeled

November 24, 2015 — HARTFORD — U.S. Sen. Richard Blumenthal joined consumer advocates in the Capitol on Monday to criticize last week’s approval of genetically modified salmon and to advocate for mandatory labeling changes.

“The genetically engineered salmon is bigger, it can be grown faster,” Blumenthal said, stressing the Food and Drug Administration will require no special labeling for the engineered fish at grocery stores and fish markets, even though it will contain the genetic material of a bottom-feeder fish called the ocean pout to speed its growth.

“I believe strongly that the consumers have a right to know,” Blumenthal, D-Conn., said during a morning news conference.

The FDA recently said its scientists “rigorously evaluated extensive data” from fish grower AquaBounty Technologies, along with peer-reviewed data.

“The data demonstrated that the inserted genes remained stable over several generations of fish, that food from the GE salmon is safe to eat by humans and animals, that the genetic engineering is safe for the fish, and the salmon meets the sponsor’s claim about faster growth,” the agency said.

FDA OK’s genetically modified salmon

November 20, 2015 — For the first time, Americans will be able to dine on a genetically altered animal, after federal regulators on Thursday approved a Massachusetts biotechnology company’s bid to modify salmon for human consumption.

After years of testing the company’s modified fish, regulators said there are no “biologically relevant differences” between the so-called AquAdvantage salmon and other farm-raised Atlantic salmon. Still, for the time being the FDA has barred the fish from being cultivated in the United States and has issued strict regulations to prevent the modified salmon from breeding with those in the wild.

The decision was a big win for AquaBounty, which began seeking approval in the 1990s for its technique of inserting growth hormone genes from Chinook salmon and an eel-like creature called ocean pout into the DNA of Atlantic salmon. The faster the fish grow, the more the company can produce and sell, potentially reducing overfishing of the oceans and developing a new source of food for a growing global population.

Company officials said the federal approval would create a new industry in the United States, which they say imports 95 percent of its Atlantic salmon. But it was unclear how long it might take before the fish appear in supermarkets.

“AquAdvantage salmon is a game-changer that brings healthy and nutritious food to consumers in an environmentally responsible manner, without damaging the ocean and other marine habitats,” Ronald L. Stotish, the chief executive of AquaBounty, said in a statement.

Efforts underway to ensure ‘Alaskan’ seafood is authentic

November 11, 2015 — As a result of international tracking difficulties, seafood marketed as “Alaskan” is often anything but, sparking legislative calls to make the Alaska label a privilege, not a right.

Wild-caught Alaska seafood is marketed as sustainable and healthy for local economies, strong selling points for the modern U.S. consumer. The labels aren’t always accurate, however, as pirate fishing and outright fraud often put foreign or untracked seafood under the Alaska banner.

International agreements and national legislation aim to impose more stringent tracking requirements for seafood landings, which are often the root of mislabeled fish. Other legislation simply pushes for marketing changes to make sure the label “Alaska” means what it says.

Marketing and international traceability issues haunt Alaska pollock, crab, and salmon, the largest and most valuable of Alaska’s federal and state fisheries.

In Congress, Rep. Don Young and Rep. Jaime Beutler, R-Wash., introduced legislation on Oct. 22 to amend the Federal Food, Drug, and Cosmetic Act to change the term “Alaska pollock” to “pollock.”

According to a GMA Research consumer report, up to 40 percent of what is currently sold as “Alaska pollock” is in fact from Russia waters, which do not have the same controls and management frameworks as U.S. North Pacific fisheries governed by the North Pacific Fishery Management Council, particularly concerning marine habitat protections and preventing overfishing.

Pollock is the largest fishery in the U.S., producing 2.9 billions pounds and accounting for 11 percent of U.S. seafood intake. In the North Pacific management region, pollock accounted for $406 million worth of landings.

Big Trouble Looms For California Salmon — And For Fishermen

November 6, 2015 — The West Coast’s historic drought has strained many Californians – from farmers who’ve watched their lands dry up, to rural residents forced to drink and cook with bottled water. Now, thanks to a blazing hot summer and unusually warm water, things are looking pretty bad for salmon, too – and for the fishermen whose livelihoods depend on them.

Preliminary counts of juvenile winter-run Chinook are at extreme low levels. These are salmon that are born during the summer in California’s Sacramento River and begin to swim downstream in the fall.

Unusually warm water in recent months has caused high mortality for the young salmon, which are very temperature sensitive in their early life stages. Most years, about 25 percent of the eggs laid and fertilized by spawning winter-run fish survive. This summer and fall, the survival rate may be as low as 5 percent, according to Jim Smith, project leader with the U.S. Fish and Wildlife Service’s Red Bluff office.

“That’s not good,” Smith tells The Salt.

Worse, it’s the second year in a row this has happened. Most Chinook salmon live on a three-year life cycle, which means one more year like the last two could essentially wipe out the winter run. To protect them, fishing for Chinook in the ocean may be restricted in the years ahead, when winter-run fish born in 2014 and 2015 have become big enough to bite a baited hook. The hope is that the few young fish that survived the recent warm-water die-offs will make it through adulthood and eventually return to the river to spawn.

In the Dry West, Waiting for Congress

November 6, 2015 — KLAMATH FALLS, Ore. — Drought in the West is an ugly thing. Rivers trickle away to nothing, fires rage, crops fail, ranchers go broke, tribal people watch fish die. As Westerners fight over the little water left, tempers crack, lawsuits fly and bitterness coats whole communities like fine dust.

As the climate warms, the West gets meaner.

The Klamath River begins in southern Oregon and meets the Pacific Ocean among the redwoods in Northern California, draining nearly 16,000 square miles. Until recently, who got water and how much had been deeply contentious issues. In particular, the irrigators and the Indian tribes were angry at one another, and the users in the river’s upper basin were angry with users in the lower basin.

But in recent years, something changed. Hostility gave way to compromise. Just about everybody who wants some of that precious river flow has made nice, given and taken, sat down and compromised.

Three major agreements have been wrapped up in Senate Bill 133, introduced by Senator Ron Wyden, Democrat of Oregon, and several colleagues. The bill is supported by tribes that want to protect the fish; ranchers who want to feed their cattle; farmers who grow alfalfa and potatoes; fly fishermen and duck hunters; ecologists; a power company; and many local politicians of various ideological stripes.

Lingering drought heightens worries of extinction for salmon

October 28, 2015 — SAN FRANCISCO (AP) – Another deadly summer of drought has heightened fears of extinction in the wild for an iconic California salmon, federal officials said Wednesday.

Officials with the National Marine Fisheries Service said preliminary counts indicate that hot, shallow waters caused by the drought killed most of this year’s juvenile winter-run Chinook before they made it out to the Pacific Ocean.

It “doesn’t look very good,” said Garwin Yip, a federal fisheries spokesman.

If a final count this winter confirms the bad news, it would mean a second straight summer in which 5 percent or less of the young fish survived California’s drought.

Since the fish spawn on a three-year cycle, the die-off would make management of next year’s water critical for the salmon’s survival in the wild.

Gulf of Maine’s cold-craving species forced to retreat to deeper waters

October 27, 2015 — For 178 years, dams stood across the Penobscot River here, obstructing salmon and other river-run fish from reaching the watershed’s vast spawning grounds, which extend all the way to the Quebec border.

Now, two years after the dam’s removal, the salmon’s proponents fear the fish face a more fearsome threat: a warming sea.

In recent years, the Gulf of Maine has been one of the fastest-warming parts of the world’s oceans, and climate change models project average sea surface temperatures here to increase by another 5.5 degrees Fahrenheit by 2065, a development that could extirpate Atlantic salmon and other cold-loving species, many of which already find Maine at the southern edge of their ranges.

“We’re all for taking down the dams and all the things that are going on to restore habitat, but how much are they looking at the evidence?” asks Gerhard Pohle of the Huntsman Marine Science Center in St. Andrews, New Brunswick, co-author of a study predicting how the changes are likely to affect 33 commercial species over the next 75 years. “Distribution of salmon in the Gulf of Maine would be such that there wouldn’t be many left at all.”

The warming gulf is already presenting challenges to many of its cold-loving denizens. Scientists at the National Marine Fisheries Services, or NMFS, have recorded the steady retreat of a range of commercially or ecologically important fish species away from the Maine coast and into deep water in the southwestern part of the gulf, where bottom water temperatures are cooler.

The retreat, which intensified over the past decade, includes cod, pollock, plaice, and winter and yellowtail flounder. Other native species that once ranged south of Long Island – lobster, sand lance and red hake – have stopped doing so, presumably because the water there is now too warm.

“You can imagine that when you have species at the southern end of their ranges, they will be really sensitive to these changes,” says Michael Fogarty, chief of the Ecosystem Assessment Program at the NMFS Northeast Fisheries Science Center in Woods Hole, Massachusetts. “They will either shift distribution or their survival rates might change.”

Court Says Antibiotic Use in Chilean Fisheries Should be Public Knowledge

September 20, 2015 — The organization Oceana won a landmark case last week against the Chilean government. The appeal, which went up against the National Fisheries and Agricultural Services (Sernapesca) found the judges unanimously decided that the Council for Transparency had to release its data regarding antibiotic usage in Chilean salmon.

The lawsuit began some time back, when reports were released that showed staggeringly high amounts of antibiotic usage within Chilean salmon fisheries. Salmon in Chile is susceptible to a disease called Piscirickettsiosis which can cause hemorrhaging, organ failure and death in salmon. A report by Reuters earlier this year showed Costco, along with a number of U.S. chains, had cut the amount of Chilean salmon it was buying in favor of salmon from Norway – which generally uses fewer antibiotics (although it should be noted that numbers for last year’s antibiotic use were not available from Norway).

However, those within the industry contest this accusation. They say the antibiotics used save these fish and heal them from the bacteria. They maintain that the fish are then weaned off these medications until no traces remain, before being shipped to market. Ricardo Garcia, the chief executive at Camanchaca, a large salmon producer in Chile, told Reuters that, “The final product consumers eat has no antibiotics.”

Salmon that will get you baked: weed-infused fish the latest in cannabis cuisine

September 17, 2015 — Sliced thin with flecks of dill peeking out, the salmon looks like any other of gravlax you would have for brunch. But put it on a bagel with a schmear of cream cheese, and you will get pretty stoned eating this delicacy.

The mastermind behind the THC-infused salmon – cured in salt, dill, lemon, sugar and a weed tincture – is Josh Pollack, owner of Rosenberg’s Bagels and Delicatessen in Denver.

“I love bagels and lox, and I love cannabis,” Pollack said.

Pollack, a New Jersey native who grew up going to establishments like Russ and Daughters, moved to Colorado for college. He loved the state, but missed the bagels from back east. After graduating, he worked in finance for a while, but tired of that and moved on to a more fulfilling passion: food.

“I’ve always been food obsessed,” Pollack said. “Bagels and lox has always been a comfort food.”

It was tough to find his favorite comfort food, so specific to the New York and New Jersey area, in Denver. So last year, Pollack opened Rosenberg’s Bagels and Delicatessen to serve up classics like bagels and lox.
