Biotech firm close to scaling up fishmeal alternative made from industrial emissions

November 23, 2020 — Having secured EUR 2.5 million (USD 3 million) from EU Horizon 2020 – European Innovation Council (EIC) accelerator funding – young U.K.-based carbon recycling biotechnology company Deep Branch is scaling up the development of new proteins for the aqua- and agri-feed sectors, produced from carbon dioxide (CO2) captured from industrial emissions.

Deep Branch’s new “Proton” single-cell protein is created through a fermentation process that uses microbes to convert CO2 into protein. The result is a low carbon feed ingredient with a nutritional profile comparable to fishmeal, which can be produced year-round, and at a price that’s on par with the traditional but finite marine ingredient market, but sporting a lower carbon footprint.

Russian and American Scientists say warming water is pushing Bering Sea pollock into new territory

November 20, 2020 — In a new study, scientists have linked warming Arctic temperatures, changing wind patterns and shifting currents to movement of commercially valuable Alaska pollock in the Bering Sea.

The Bering Sea has seen the loss of a summer cold water barrier in recent years, which used to keep pollock from spreading out and moving north.

But while scientists are seeing drastic shifts in pollock movement patterns, further research needs to be conducted to know what the changes mean for communities like Unalaska and Dutch Harbor and the billion-dollar pollock industry.

“This research is really critical because pollock are a key ecological component of the Bering Sea shelf food web supporting the largest commercial fishery in the U.S. by biomass,” said Robert Foy, NOAA’s Alaska Fisheries Science Center director. “To get an accurate assessment of pollock abundance so that resource managers can set sustainable catch limits, we have to be able to understand pollock distribution, which certainly looks different under a warm water regime.”

Coalition of seafood industry members oppose new Ocean-Based Climate Solutions Act

November 17, 2020 — A coalition of more than 800 members of the U.S. seafood industry have signed a letter opposing a new bill that they say will undermine the nation’s “world-class system of fisheries management.”

The bill, the Ocean-Based Climate Solutions Act, was introduced in the U.S. House of Representatives in late October. The 300-page-long bill was co-authored by U.S. Rep. Raul M. Grijalva (D-Arizona) and U.S. Rep. Kathy Castor (D-Florida) and contains sweeping rule-making that touches on fisheries sectors.

Late-season Arctic research cruise reveals warm ocean temperatures, active ecosystem

November 12, 2020 — Arctic researchers Jacqueline Grebmeier and Lee Cooper have been visiting the Bering and Chukchi seas off Alaska for nearly 30 years, collecting information about the biological diversity of the watery world under the sea ice to understand how marine ecosystems are responding to environmental changes. This year, a late-season research cruise in October revealed a surprise. At a time of year when an ice-breaking ship is usually required to get them to some of the data-gathering outposts, scientists found nothing but open water and an unusually active ecosystem.

“The water and air temperatures were warmer, and we had ecosystem activity that normally doesn’t occur late in the season,” said University of Maryland Center for Environmental Science Research Professor Jacqueline Grebmeier, chief scientist on the research cruise and a national and international leader in Arctic research.

Grebmeier and Cooper were part of a small team of researchers from the University of Maryland Center for Environmental Science, the University of Alaska Fairbanks, and Clark University that completed an unusual late-season Arctic research cruise due travel challenges presented by COVID-19 pandemic. They found an ecosystem—expected to be powering down to low-level winter activity with sea ice forming—to be still active, likely due to unseasonably warm ocean temperatures. Sea ice formation was still a number of weeks away.

“2020 turned out to be the second lowest minimum sea ice extent, meaning that sea ice retreated back closer to the North Pole,” Grebmeier said. “We had warming water up to 3 degrees Celsius higher than typical all the way through . That means you can’t cool it down that quickly to build ice.”

MASSACHUSETTS: ‘Dock to dish’ aids net zero plan

November 11, 2020 — There is a simple way to help combat climate change, and it tastes good: Eat local fish.

More than 90 percent of the fish consumed in this country comes from overseas, creating an enormous carbon footprint.

“The average seafood eaten in the United States travels 5,500 miles from dock to dish,” said Brett Tolley, adding that even in coastal communities, the numbers aren’t that different. “If that doesn’t wake you up, I don’t know what will.”

Tolley, national program coordinator for Northwest Atlantic Marine Alliance, was one of four fishing industry panelists participating in Net Zero, a virtual conference sponsored by the Cape Cod Climate Change Collaborative.

The conference in late October brought together public and private leaders in all sectors, from construction to creative arts, who are growing jobs and the economy while moving the region to “net zero,” meaning the amount of greenhouse gas produced and the amount removed from the atmosphere is a wash.

Eat More Kelp campaign launched by climate change activists in North America

November 10, 2020 — Climate change is the impetus driving the new Eat More Kelp campaign in North America, which seeks to “change the trajectory of culinary culture in the United States and Canada to include more carbon-capturing, ocean-grown domestic sea vegetables,” according to its organizers.

A collaboration of activists, regenerative ocean farmers, and climate groups are behind the campaign’s creation. The initiative was announced in tandem with the founders of The Kelp Fund, Inc. launching a new website and e-commerce platform, which offers Eat More Kelp-branded merchandise for “concerned citizens and organizations around the world who are seeking impactful ways to raise awareness about how to fight climate change,” it said in a press release.

Could Listening to the Deep Sea help Save it?

November 10, 2020 — You might know what a hydrothermal vent looks like: black plumes billowing from deep-sea pillars encrusted with hobnobbing tubeworms, hairy crabs, pouting fish. But do you know what a hydrothermal vent sounds like?

To the untrained ear, a hydrothermal vent — or more precisely, one vent from the Suiyo Seamount southeast of Japan — generates a viscous, muffled burbling that recalls an ominous pool of magma or a simmering pot of soup.

To the trained ear, the Suiyo vent sounds like many things. When asked during a Zoom call to describe the Suiyo recording more scientifically, Tzu-Hao Lin, a research fellow at the Biodiversity Research Center at Academia Sinica in Taipei, Taiwan, took a long pause, shrugged, and laughed. People always ask him this, but he never has the answer they want to hear. “I usually tell people to describe it with their own language,” Dr. Lin said. “You don’t need to be an expert to say what it sounds like to you.”

Dr. Lin adores acoustics; in his official academic headshot, he wears a set of headphones. He has listened to the sea since 2008, and to the deep sea since 2018. He has deployed hydrophones, which are microphones designed for underwater use, in waters off Japan to eavesdrop on the noises that lurk thousands of feet below the surface. He published these recordings in August at the a conference of the Deep-Sea Biology Society.

MASSACHUSETTS: Lobster Stocks Found in Steep Decline, With Future in Doubt

October 30, 2020 — Southern New England lobster stocks, once robust, have declined to record lows in recent years according to scientists and regulators, jeopardizing the future of a storied fishery even as Vineyard lobstermen continue to report strong seasons on the water.

In a benchmark assessment released late last week, an interstate regulatory agency found that lobster populations in southern New England are “significantly depleted,” reaching their lowest levels on record and threatening the lobster industry from the southern Cape through Long Island Sound.

But some Vineyard lobstermen said that despite the decreasing abundance in the entire southern New England region — which stretches from south of New York to Monomoy and Nantucket — their catch around the Island remains healthy.

And interestingly, just as lobster populations have declined in more southern waters in recent years, scientists have seen a historic boom in the Gulf of Maine, where lobster abundance and fishery performance have reached record highs, according to the report. The Vineyard sits just south of the halfway point between the two American lobster stock units, which are divided by geography and small differences in the biology of the crustaceans.

Leaving more big fish in the sea reduces CO2 emissions

October 29, 2020 — An international team of scientists has found leaving more big fish in the sea reduces the amount of carbon dioxide (CO2) released into the Earth’s atmosphere.

When a  dies in the ocean it sinks to the depths, sequestrating all the carbon it contains with it. This is a form of ‘blue carbon’—carbon captured and stored by the world’s ocean and coastal ecosystems.

“But when a fish is caught, the carbon it contains is partly emitted into the atmosphere as CO2 a few days or weeks after,” said Gaël Mariani, a Ph.D. student at the University of Montpellier in France.

Mr Mariani led a world-first study showing how ocean fisheries have released at least 730 million metric tons of CO2 into the atmosphere since 1950. An estimated 20.4 metric tons of CO2 was emitted in 2014—equivalent to the annual emissions of 4.5 million cars.
