Aquarium program offers food for thought on eating sustainably

May 4, 2016 — For decades, the National Aquarium has entertained millions of visitors while also teaching them about the need to conserve aquatic resources. The Baltimore institution has rescued marine animals off the coast of Ocean City, built floating wetlands to help clean the Inner Harbor’s water and featured Chesapeake Bay creatures in its tanks and exhibits.

But the aquarium was nearly silent on the subject of seafood consumption. The dark, serpentine halls told the story of precious resources being overfished. But that story didn’t have an ending — a solution for how to stem the decline. It had no programs to guide visitors on where to buy local fish caught sustainably, or how a customer could even understand what that meant.

That’s starting to change. A year ago, the aquarium hired its first director of sustainable seafood: T. J. Tate, who built a sustainable seafood program in the Gulf of Mexico. Tate is bringing together chefs, watermen and others in the seafood industry to talk about catching, raising, buying and eating locally caught fish, crustaceans and shellfish.

It is increasingly part of the story told by aquariums everywhere, at a time when overfishing is rampant worldwide while customers often overlook local products. Even fish that customers think is sustainable comes from far away — farm-raised salmon from Norway, or wild varieties from Alaska — and those distances have ramifications for air and water quality, too. Visitors often ask what they should eat, and the aquarium wanted to find an engaging way to guide them.

“Telling the local seafood story in an integrated fashion — I mean the sustainable aquaculture supply and wild supply — is one of the most important things we can do to get people connected to oceans and the Bay,” said Eric Schwaab, who hired Tate when he was chief conservation officer at the aquarium. “There’s no better place to do that than Baltimore.”

MAINE: Mild winter heats up efforts to protect Casco Bay’s clams

May 2, 2016 — Soft-shell clams are a summer tradition around Casco Bay, both for the tourists and residents who love steamers and for the clam diggers who turn long, backbreaking hours on the mud flats into cold, hard cash.

But an infestation of invasive green crabs ravaged juvenile clam stocks in the past four years, adding to ecological changes, competition for coastal access and other pressures facing the state’s second most valuable fishery. Clam landings in the Casco Bay communities of Freeport, Harpswell and Brunswick, some of the state’s leading clam producers, plummeted to historic lows in 2015, and the scarcity of soft-shell clams contributed to all-time high prices.

While some shellfish managers say clam populations have rebounded thanks to a few cold winters that killed off green crabs, harvesters are anxious that the mild winter this year could produce a resurgence of green crabs and throw the fragile industry into a tailspin.

Those fears have clam diggers and scientists stepping up efforts to defend clam beds with boxes and nets. And they are fueling calls for a sea change in the management of soft-shell clams by leasing clam beds so that clammers can better protect the resource from predators.

Some are sounding alarms that without human intervention, the resource faces total collapse.

“Unfortunately, it doesn’t look like people are just going to be able to go out and dig clams like they have without the protection element,” said Sara Randall, a Freeport researcher working with clammers in that town.

Others worry about an overreaction. Although most agree that active management and conservation efforts will be required in the future, not all believe the industry is facing a doomsday.

“We realize there is a bunch going on, but we don’t see it as the end of wild harvest,” said Darcie Couture, a marine scientist working with Harpswell clammers.

MSC labelled products reach 20,000

February 23, 2016 — The following was released by the Marine Stewardship Council:

LONDON – Today the Marine Stewardship Council (MSC) reached an important milestone with the launch of the 20,000th MSC labelled product, Las Cuarenta Paella. The ready-made frozen meal is now available in Netto stores across Germany. The paella contains pollock from Alaska and Russia, blue shell mussels from Denmark, and shrimps from Suriname.

A growing trend in new seafood products

The paella’s seafood mix comes from a diverse range of fisheries, from a developing world fishery in South America, to some of the world’s largest fisheries in North America and Europe. Each of these fisheries is committed to ensuring the health and sustainability of the fish stocks they harvest

“The 20,000th MSC labelled product, Las Cuarenta Paella, illustrates the growing trend in new seafood products. Over the last decade, we’ve seen new and novel ways MSC certified seafood is being used. From ready-made meals such as paella to sandwiches, pizza and baby food. Las Cuarenta paella is a fine example of how retailers and manufacturers are exploring new trends to attract more sustainable seafood lovers,” said Nicolas Guichoux, MSC’s Global Commercial Director.

Thanks to the efforts of these and over 280 other certified fisheries, consumers in over 100 countries can choose from a variety of MSC labelled products covering more than 100 different species. Consumers can also be assured that MSC certified seafood has an effective, traceable supply chain which ensures the integrity of MSC labelled products.

“Nine years ago only 1,000 labelled products were on the market globally. So we celebrate this new important milestone, and honor all fisheries and retail partners whose commitment to sustainability has contributed to the growth of the MSC program around the world and played a part in securing a healthy future for our oceans,” added Nicolas Guichoux.

MSC in Germany

Germany is the MSC’s most developed market in terms of certified sustainable seafood consumption, with over 4,000 MSC certified products on sale. Netto is one of many retail partners committed to sourcing and selling MSC certified products in the country. The discounter offers a wide range of responsibly sourced seafood with more than 100 MSC-labelled products in store. Netto has made a long-term commitment to only source and sell seafood– from MSC certified sustainable fisheries.

“We are very proud that the 20,000th MSC labelled product is a Netto product. With the growing availability of MSC certified seafood from a variety of species, we’ve been able to expand our range of products so that our customers can buy their favorite seafood in the knowledge that the environment is being safeguarded. MSC certified products play an important role in our corporate sustainability agenda,” said Christina Stylianou, Corporate Communications Director at Netto.

A label you can trust

The blue MSC label assures consumers that the fish they are buying comes from a sustainable and well-managed fishery that has been independently certified, ensuring that the fish populations and the ecosystems upon which they depend remain healthy and productive.

Any organization selling or handling MSC certified seafood must ensure that it is correctly labelled and kept separate from other non-certified seafood at all times. This ensures that MSC labelled seafood can be traced back to a sustainable source.

You can find these products in-store, online and in restaurants.

Fishery council decision endangers scallop stock

February 20, 2016 — I received a letter from Jason Colby, who is a charter-boat captain and sits on the board of directors for non-commercial fishermen here in Massachusetts about the nasty — he calls it “corrupt” — goings-on in the scallop fishery.

He told me how Eddie Welch, a shellfish advisor, had written to him about the problem down on the Cape and wanted to share this with me and the readers. Here are excerpts from his letter:

“A recent controversial decision to open select scallop grounds off the coast of New England to certain select fishing groups undermines sustainable scallop management, and threatens the future health of one of the region’s most valuable resources.

“On Dec. 3, the New England Fishery Management Council allotted one component of the fishing fleet 300,000 pounds of scallops for harvest from an area of the Atlantic known as Nantucket Lightship. This allotment would open Nantucket Lightship too early, and goes against the principles that have made scallop management so successful.

“For the past two decades, the scallop fishery has been a resounding success thanks to a system known as rotational management. Under this system, scallopers are allowed into certain areas to harvest scallops, while other areas are left off-limits to allow the scallops in them to grow and re-populate. This has ensured that the region’s scallop population is healthy and stable, that no areas are fished prematurely, and that scallops are not over-fished.

NORTH CAROLINA: Flounder and semantics heat up fisheries meeting

February 19, 2016 — WRIGHTSVILLE BEACH — Before state officials decide how to better regulate commercial fishing licenses, they’ll have to answer an important question — ‘just who is a commercial fisherman?’

When members of the N.C. Marine Fisheries Commission met in Wrightsville Beach this week — their first meeting of 2016 — updating the state’s 17-year-old criteria for commercial fishermen was a hot topic. And it’s one that’s sure to be contentious — when Commissioner Alison Willis proposed a subcommittee to study the issue, she said she was putting her head on the chopping block.

By the time her motion was worded as carefully as possible, it was a paragraph long.

“And here I was thinking that it was the lawyers that got paid by the word,” Phillip Reynolds, the commission’s legal council, joked.

But commissioners agreed they would rather be cautious than concise after a year of meetings marked by emotional exchanges, audience outbursts and even threats. At this week’s three-day meeting, members tackled topics from shellfish management to fishing licenses and tied up loose ends on the southern flounder management plan changes that caused so much controversy in 2015.

Warmer waters could change Cape Cod fisheries

February 15, 2016 — Hot water is fine for fish chowder and lobster bisque, but not so much for many fish in the sea.

The National Oceanic and Atmospheric Administration has unveiled a study of 82 species of fish, mollusks and crustaceans, ranking each on how they might fare under a regime of warming waters in the Northeast.

The authors, and there are quite a few, selected important commercial species, various forage fish of little economic import such as sand lances that are ecological heavyweights, and endangered species.

The amount of available data varies widely species by species, but the authors made their best assessments based on the estimated vulnerability of each animal to shifting climate. They weighed environmental factors that would be altered by climate change (water and air temperature, salinity, acidity, precipitation, the variance of those factors, sea level and ocean currents) vs. the species’ resilience (prey and habitat specificity, sensitivity to temperature, acidity, stock size, population growth rate, spawning cycle and mobility).

The ocean has been heating up, if not steadily.

“It depends on what period you’re looking over,” reflected lead author John Hare, director of NOAA’s Narragansett Laboratory. “I tend to look over a long period, since the 1880s, it’s up about two degrees Fahrenheit. We took all the information we know now and try to look forward to 2050.”

Narragansett Bay temperature extremes signal trouble below

February 6, 2016 — Aboard the Cap’n Bert — A harbor seal pokes its mottled head out of the water, soulful eyes visible above a bristly mustache, before diving back down to snatch fish from the net being winched aboard the trawler.

“Gettin’ a free meal,” Captain Tom Puckett remarks with a shake of his head.

As the otter trawl net is hoisted up on the A-frame across the boat’s stern, it’s clear that it’s nowhere close to full. But it doesn’t matter. The Cap’n Bert is not a commercial fishing trawler. It’s a research vessel owned and operated by the University of Rhode Island’s Graduate School of Oceanography.

The 53-foot stern trawler is out on Narragansett Bay on this winter day carrying out its weekly ritual of testing the water temperature and other indicators and taking samples of marine life.

Doctoral student Joe Langan pulls open the net, spilling fish and shellfish unceremoniously onto the deck. He sorts the catch, just as he has done every week since September and as others have done before him, stretching back more than five decades as part of one of the oldest continuous marine research projects in the world.

From the wet and writhing pile, he picks out sea robin and skate, silver hake and red hake, rock crabs, spider crabs and lobsters — all species that are normally found in the Bay this time of year.

But when Langan gets to the bottom, he carefully picks up a flat, light-brown fish and pauses to study it.

“A Gulf Stream flounder,” he finally says. “Which should not be here.”

The little flounder is a warm-water species that shows up in May but would usually be gone by the time the temperature drops in December.

It is of course only one fish, but its presence here in the waters off Whale Rock on this January morning is yet another sign that Narragansett Bay is changing.

“And we’re seeing it happen,” Langan says.

Pass the dogfish nuggets? Seafood industry rebrands ‘trash’

January 20, 2016 — PORTLAND, Maine (AP) — Call them fish sticks for millennials. At any rate, Dana Bartholomew is banking on college students warming up to “Sharck Bites.”

Ipswich Shellfish, of Massachusetts, for which Bartholomew oversees sales, is offering that product — nuggets of dogfish coated in a gluten-free, allergen-friendly crust. Bartholomew, who believes so-called “trash fish” such as dogfish are part of the new wave in New England seafood, already has a couple of colleges on board.

Bartholomew’s fondness for dogfish, a species East Coast fishermen catch millions of pounds of every year that sells for just pennies at the dock, is part of a growing trend in fish markets around the country. The industry is putting more emphasis on fish that have traditionally lacked market appeal or economic value as old staples — such as cod, tuna, haddock and shrimp — decline or become the subject of tougher fishing quotas.

“We know we have to make a great-tasting product that supports local fishermen, supports the local industry and economy,” Bartholomew said. “And it’s local — it’s right here.”

New England’s traditional food fish has long been the Atlantic cod, but it has faded in the face of overfishing and environmental changes. Restaurant owners, fishermen and food processing companies said a growing shift to other species is helping to fill that void. Catch of species such as spiny dogfish, Acadian redfish and scup have all increased dramatically since 10 years ago as cod has fallen.

How Probiotics Can Save the East Coast Shellfish Industry

January 12, 2016 — Bob Rheault was having an open house at his young shellfish hatchery, so he arrived early in the morning with bottles of wine and plates of cheese. That’s when he noticed he had a problem.

“There was an odd substance floating on the surface of the tanks,” Rheault says. He looked through a microscope, “and there were no bodies to be seen … just empty shells with bacteria climbing all over them.”

In oyster and clam hatcheries, a bacterial infection can cause the population to drop from 10 million to 1,000 larvae overnight. That’s what happened to Rheault, who had no larvae to show his open house guests. Antibiotics aren’t approved for use in U.S. shellfish hatcheries (though they are worldwide)—and, by the time an infection sets in, all the larvae are dead anyway—so the only thing for a hatchery owner to do when confronted with an infection is dump everything out, clean the tanks, and start over.

Or that used to be the only approach. Now, researchers at two labs seem to have found a solution.

The problem of bacterial infections in hatcheries has been worsening over the past decade as the waters of the Northeast warm. Rheault, who is now the president of the East Coast Shellfish Growers Association, says that thanks to climate change, bacterial infections now kill off 10 to 20 percent of the Northeast’s shellfish larvae each year. And because the bacteria, Vibrio, gets into the tanks via seawater, it affects not only shellfish but also lobsters, by turning their shells black and making them impossible to sell. (Some lobstermen eat the animals themselves or send them to be cooked and processed, since the meat is still good.)

Researchers have now found a tool to fight the Vibrio bacteria: probiotics. Teams at both NOAA’s Milford Laboratory in Connecticut and the University of Rhode Island (URI) have harvested beneficial bacteria from healthy adult oysters that can help oyster larvae fight off bacterial infections. And the URI researchers are exploring the possibility that a similar concoction could help treat lobster shell disease as well.

Shellfish Farmers Fear Ocean Acidification May Affect Harvests in 2016

January 8, 2016 — Ocean acidification was blamed for the shutdown of the Washington oyster fishery last year and B.C. could be next, partially for the same reason, said Rob Saunders, owner of Island Scallops at Qualicum Beach.

Speaking to TheProvince, Mr Saunders said that Island Scallops, which provides seed oysters and scallops for farmers, lost 90 per cent of its oyster larvae last year.

Acidic water affects the oysters’ ability to grow a hard shell. It takes two years for oysters to mature for harvest, and Mr Saunders said oysters may be in short supply this year.
