Saving Seafood

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.

Study finds lobster population healthy off Maine, poor in southern New England

October 26, 2020 — The American lobster population is in decent shape off of Maine and Canada, but continues to decline in southern New England, according to an assessment by an interstate regulatory group.

The stock assessment released by the Atlantic States Marine Fisheries Commission’s American Lobster Board lines up with previous analyses of the lobster fishery. Lobster fishermen pulled in record catches of the crustaceans off Maine in the last decade, but the catch collapsed off more southern states such as Connecticut.

Environmental changes have made the more southern waters less hospitable for lobsters, scientists have said. Warming temperatures off southern New England have made it difficult for them to grow and reproduce.

Understanding the Impacts of Climate Change on Economically Important Fish Species

October 26, 2020 — The following was released by NOAA Fisheries:

Researchers at NOAA’s Southeast Fisheries Science Center and Atlantic Oceanographic and Meteorological Laboratory are teaming up. They want to understand how changing ocean conditions might be influencing commercially important fish stocks. The project will identify key physical processes that affect the biology and chemistry of waters used by coastal migratory species. They will pool their modeling capacities to investigate factors influencing fish stocks in the Gulf of Mexico and South Atlantic Bight. These stocks are managed by NOAA Fisheries and the regional Fishery Management Councils.

Building on previous research collaborations, the scientists will continue advancing these modeling efforts to support marine resources management and conservation. “We have configured several high-resolution models for the Gulf of Mexico, Caribbean Sea, and South Atlantic Bight,” said Laboratory scientist Dr. Sang-Ki Lee. “Using these models, we have built close collaborations between our laboratory and the science center addressing key scientific questions, including the impacts of increasing ocean temperatures on coral bleaching and spawning of Atlantic bluefin tuna in the Gulf of Mexico and Caribbean Sea, impacts of El Niño and increased rainfall on plankton patterns in the Texas-Louisiana shelf, and seasonal variability in ocean carbon chemistry in the Gulf of Mexico.”

Coastal migratory species, such as king mackerel, greater amberjack, red porgy, and red grouper, are key commercial and recreational species that support a billion-dollar economy. The most recent stock assessments for these species indicated that the stocks began declining in the late 2000s. This indicates either reduced population reproductivity, migration out of the management area, or both.

A stock assessment is the process of collecting, analyzing, and reporting demographic information to determine changes in the abundance of fishery stocks in response to fishing. They are also used to predict future trends of stock abundance. The stock assessments track the age structure of the adult population to determine how many new fish are expected in the future. When the actual number does not match the expected number, it reflects that something other than stock abundance is affecting the population, such as the environment or a predator species.

Ocean climate bill is a grab bag for marine stakeholders

October 21, 2020 — Rep. Raul Grijalva (D-Ariz.), chairman of the House Committee on Natural Resources, today introduced the Oceans-Based Climate Solutions Act of 2020.

We could start with the irony of a representative from Arizona introducing an oceans climate bill, hailing not only from a landlocked state, but one most known for its lack of water.

But let’s instead lead with the fact that the blueprint for this bill was introduced and failed to make it out of committee in California — one of the nation’s most progressive states. Now Gov. Gavin Newsom has made an end run around the legislative process by creating an executive order to effect the changes in the bill that could not pass with votes.

The federal bill is more than a mixed bag. Reading its 324 pages felt like swinging at a piñata packed with a mix of treats and lit fireworks.
