Maine isn’t doing enough to protect the Gulf from the effects of climate change

October 30, 2015 — When the Maine Legislature’s commission on ocean acidification reported its findings – that the state’s fisheries and aquaculture industries were threatened by this baleful byproduct of global warming – officials here were not exactly spurred to action.

Acidification, driven by increased carbon dioxide from the atmosphere and freshwater runoff from extreme rainfall in river basins, has been implicated in failures at oyster hatcheries and mussel farms, and has been shown to weaken clams and other shell-building animals vital to Maine’s fishing and aquaculture industries. But bills introduced in the last session – one each by a Democratic marine scientist and a Republican lobsterman – to implement many of the panel’s findings were withdrawn, one for lack of resources, the other for lack of support from Gov. Paul LePage’s administration.

“I could see the bill wasn’t going to go anywhere and that the governor was going to veto it,” Rep. Mick Devin, a Democrat from Newcastle, says of legislation he sponsored to allow the commission to continue its work for another three years.

Patricia Aho, who was the commissioner of environmental protection until she resigned in August, opposed Devin’s bill, saying the status quo was sufficient. “Since the issues of climate change and ocean acidification are inextricably linked, we think it will be more efficient to consider this issue in the broader context of climate change and adaptation programs,” she said in written testimony to legislators.

Devin’s bill and another one sponsored by Rep. Wayne Parry, a Republican from Arundel, were carried over to the next legislative session. Parry’s bill would have put a bond issue on the ballot that would borrow $3 million to fund several of the expert committee’s recommendations: collecting data, monitoring waterways, and performing tests in coastal waters to better assess the impact of acidification on wildlife and commercial fish species. It was withdrawn after failing to make it to the top of an informal list of bonding priorities drawn up by legislative leaders.

Ocean acidification threatens future of aquaculture, shellfish industries

October 29, 2015 — In seawater tanks in a refrigerated room at the Darling Marine Center, the baby mussels are thriving.

Two months ago they were near-invisible larvae, swimming around in the tanks. Now tens of thousands of the tiny mollusks, each just a few millimeters long, have attached themselves to the different kinds of rope scientists have been testing here, and are eating the lab’s stock of algal food at an impressive clip.

Mick Devin, the lab manager at this University of Maine marine research facility, has been overseeing this experiment, part of an effort to master the art of hatching mussels, something mussel farmers – who grow their product on lines hanging in seawater – have never previously needed to do.

“Mussel farmers have been able to just throw their lines out and collect all the larvae they want from nature,” Devin says. “But mussel populations are down drastically in this state, so that may not be working so well now.” Hatcheries, he expects, may have to step up in the not-too-distant future.

Mussels have been vanishing from stretches of coastline where they once were ubiquitous, and scientists remain uncertain as to why. Green crabs, whose population exploded after an “ocean heat wave” in 2012, may have stripped many sections clean. But warmer water and increased rainfall – both problems expected to grow in Maine as a result of global climate change – may be creating a far worse problem: an acid sea.

“We know this affects larval development in bivalves, (and) chances are it will result in decreased numbers, whether it’s a natural population on a bed or one in a farm,” says Paul Rawson of the University of Maine’s School of Marine Sciences, who is in charge of the research. “We need to make sure the technology is in place so the farms will have a reliable source of seed.”

The world’s oceans are turning more acidic. Since the Industrial Revolution, carbon dioxide levels in the atmosphere have grown by more than 70 percent and now stand at the highest level in at least 800,000 years. As the oceans absorb additional CO2, they’ve become 30 percent more acidic over this period. By 2050, scientists estimate surface pH levels will be lower – that is, more acidic – than at any time in several million years and by 2100 more acidic than any time in the past 300 million years – two or three times more so than today.

Invasive species exploit a warming Gulf of Maine, sometimes with destructive results

October 28, 2015 — Until two years ago, if you had walked down to the shore of Maquoit Bay at low tide, you would have seen a meadow of eelgrass stretching nearly as far as the eye could see across the exposed seafloor. Here near the head of the bay, the sea grass stretched for two miles to the opposite shore, creating a vast nursery for the shellfish and forage species of Casco Bay, of which Maquoit is a part.

Now there’s only mud.

Green crabs took over the bay in the late fall of 2012 and the spring and summer of 2013, tearing up the eelgrass in their pursuit of prey and devouring almost every clam and mussel from here to Yarmouth. Fueled by record high water temperatures in 2012 and a mild winter in 2013, the green crab population grew so huge that the mudflats of Casco Bay became cratered with their burrowing, and much of the Maquoit and adjacent Middle Bay bottom turned into a lunar landscape.

Eelgrass coverage in Maquoit Bay fell by 83 percent. With nothing rooted to the bottom, the seawater turned far muddier, making life hard on any plants or baby clams that tried to recolonize the bay.

“We were astounded,” says Hilary Neckles of the U.S. Geological Survey’s Patuxent Wildlife Research Center, who linked the destruction to the green crabs. “The ecological ramifications really reverberate throughout the ecosystem, because sea grass is the preferred habitat of so many fish and shellfish species.”

Over the past decade, the Gulf of Maine has been one of the fastest-warming parts of the world’s oceans, allowing warm-water intruders to gain a toehold and earlier invaders such as the green crab to take over. Coupled with declines of the cold-loving species that have dominated the gulf for thousands of years, the ecological effects of even more gradual long-term warming are expected to be serious, even as precise forecasting remains beyond the state of scientific knowledge.

Scientists say the 2012 “ocean heat wave” was an unusual event, and that the 10-year accelerated warming trend is likely part of an oceanographic cycle and unlikely to continue. But the gulf has been consistently warming for more than 30 years, and long-term forecasts project average sea surface temperatures in our region could reach 2012-like levels by mid-century. The events of 2012 and the nearly as warm year that followed likely provide a preview of things to come, of a gulf radically transformed, with major implications for life on the Maine coast.

Genevieve MacDonald, who fishes for lobster out of Stonington, was standing on the dock at Isle au Haut one morning that summer, looked in the water, and couldn’t believe her eyes. There, swimming around the harbor like mackerel, were dozens and dozens of longfin squid, temperate creatures rarely seen in the chill waters of eastern Maine. “If you had a cast net you could have brought in a whole basket full of squid,” she recalls.

The next food revolution: fish farming?

October 25, 2015 — Sanggou Bay looks like a place where the pointillism movement has been unleashed on an ocean canvas. All across the harbor on China’s northeastern coast, thousands of tiny buoys – appearing as black dots – stretch across the briny landscape in unending rows and swirling patterns. They are broken only by small boats hauling an armada of rafts through the murky waters.

For centuries, Chinese fishermen have harvested this section of the Yellow Sea for its flounder, herring, and other species. Today the area is again producing a seafood bounty, though not from the end of a fisherman’s rod or the bottom of a trawler’s net. Instead, the maze of buoys marks thousands of underwater pens or polyurethane ropes that hold oysters, scallops, abalone, Japanese flounder, mussels, sea cucumbers, kelp, and garish orange sea squirts. They are all part of one of the world’s biggest and most productive aquaculture fields. Sanggou Bay is a seafood buffet on a colossal scale.

The buoys here extend for miles out to the horizon, offering, on an aluminum-gray day, the only clue to where the ocean stops and the sky begins. Hundreds of migrant workers – many from as far away as Myanmar (Burma) – pilot the fishing boats zigzagging around the floats, shuttling fish to shore, checking the lines for mussels and oysters, and voyaging farther out to sea to harvest seaweed.

NEW YORK: Woman Among the Baymen

October 23, 2015 — “Clam Power” read the T-shirt on the sturdy woman carrying gear from her pickup to her no-frills work boat tied to a ramshackle dock in Patchogue, on the South Shore of Long Island.

The woman, Flo Sharkey, 72, works full time on the bay, and on Wednesday morning, she and her son, Paul Sharkey, 36, a bayman himself, loaded rakes, hip waders and bushel baskets into the boat and headed out through Swan Creek into the open bay.

People who make their living on these waters are known as baymen, and it’s a dwindling profession. A woman doing it for a living is nearly unheard-of.

Ms. Sharkey said she knew of no other baywomen. Her sister and mother could hold their own on the water but elected not to make it their life’s work.

Ms. Sharkey has often kept side jobs — these days, she moonlights as a school custodian — but clamming has been her mainstay on the Great South Bay, just off Fire Island.

“Years ago, this was the most productive bay in the country, except for the Chesapeake, for crabs, clams and fish,” Ms. Sharkey said as the boat bounded across the shimmering flat water toward a shallow spot. “But then came the brown tide, the road runoff and fertilizer off people’s lawns.”

With those factors affecting the abundance and health of the clams, much of the bay is now off limits for shellfishing. Weaker market prices and the ever-rising cost of living are other reasons that there were a mere two other clam boats off in the distance, compared with the hundreds that would have been seen years back.

Snapper bill could kill fishing jobs

October 23, 2015 — The following opinion piece appeared on The Hill and was written by Shane Cantrell, Buddy Guindon, Glen Brooks and Brett Veerhusen:

The commercial and charter fishermen in the Gulf of Mexico and throughout the United States, are unified in opposition to H.R. 3094 (Gulf States Red Snapper Management Authority Act).

Every year tens of millions of Americans enjoy fresh caught seafood from their favorite restaurants and grocery stores, and millions of tourists travel to the coasts for a day of fishing on charter boats. Fish and shellfish are public resources, and our four fishing industry organizations work hard to provide the American public with sustainable access to the bounty of the Gulf of Mexico and other coastal regions of our nation.

Together, our organizations and the thousands of fishermen we represent have embraced science and management tools that promote conservation and sustainable fishing practices, reduce wasteful by-catch, operate safer and more stable small businesses, and protect fishing and shore-side jobs. We strive for sustainability, accountability, and access to some of the world’s best seafood; and we do so through active and progressive campaigns that bring fishermen, stakeholders, and regulators together to solve problems.
H.R. 3094 poses a clear and imminent threat to our jobs, our fishing communities, and the red snapper resource that we have helped rebuild to some of the highest levels on record.

H.R. 3094 creates loopholes that will erode the commercial red snapper fishery and access to red snapper by millions of American consumers. Commercial management of red snapper in the Gulf is a success story – overfishing was stopped, wasteful discarding was all-but-eliminated, and fishing businesses and jobs are profitable and stable. This is all due to the core conservation and management protections that are afforded to us under federal law (the Magnuson-Stevens Conservation and Management Act). H.R. 3094 allows the Gulf States to take away nearly 10% of the commercial quota every year without conferring with the Congressionally-approved and stakeholder-comprised Gulf of Mexico Fishery Management Council (Gulf Council). To add insult to injury, H.R. 3094 deceives the public by claiming it will not change the IFQ shares in this fishery. However, those who developed this language fail to point out that the “shares” are a percentage of the whole commercial allocation, and that any reduction in commercial allocation will reduce the quota associated with the shares. Commercial fishermen don’t keep what they catch – it goes to American consumers who purchase red snapper from restaurants and grocery stores.

Aquaculture on the rise in coastal North Carolina

October 22, 2015 — NEW HANOVER COUNTY, N.C. – Nearly all of southeastern North Carolina’s waters are now open for shellfish harvesting after heavy rains and floods left most areas polluted earlier this month.

Not only are oysters one of the state’s most popular shellfish to eat, but the shells themselves can be used as hardworking landscape material, in the form of driveways and patios.

Oyster shells make up many of the paths at Colonial Williamsburg to to get around. But starting October 1, a new law went into effect prohibiting contractors from using the shells in commercial landscaping.

The new law is an effort to increase the state’s oyster shell recycling program, where the shells are used to rebuilt oyster reefs.

“Oysters happen to be one of the few species that when we harvest it, we take the habitat right along with it, so we are trying to put that back into place,” said UNC-Wilmington’s Troy Alphin. “Larvae oysters depend on the adult oyster shell for settlement, and they have a very narrow window for settlement in their life span, only a couple of weeks. So if the shells are not in the water, they are not available for the larvae to settle on, these larvae will die. What we are trying to do is make sure the shells are back in the water as soon as we can they will be available for the next generation of oysters.”

At a summit earlier this year, North Carolina ecologists, scientists and politicians announced new efforts to make North Carolina the “Napa Valley of Oysters.”  One way that can be accomplished is by developing new oyster sanctuaries, something that Virginia and other states have already done.

A healthy oyster population is linked to the overall health of coastal fisheries.

Most southeastern North Carolina waters back open for oyster season after bacteria levels fall

October 22, 2015 — WILMINGTON, North Carolina — Nearly all of southeastern North Carolina’s waters are now open for shellfish harvesting after heavy rains and floods left most areas polluted earlier this month.

The StarNews of Wilmington (http://bit.ly/1GVKMiM ) reports that bacteria found throughout most waters prompted the N.C. Division of Marine Fisheries to declare most areas off-limits to oyster harvesting earlier this month, even though harvesting season technically opened Oct. 15.

MAINE: Pembroke company seeks to make Washington County the ‘clam capital of Maine’

October 19, 2015 — It’s a crisp sunny morning in early October in the Washington County town of Pembroke and Tim Sheehan walks briskly across an empty parking lot to greet me. He’d been expecting good news about clam flats in northwestern Cobscook Bay being reopened, but instead of a parking lot full of diggers delivering clams to Gulf of Maine Inc., the seafood business on Route 1 he co-owns with his wife, Amy, there’s just a quiet sunlit absence.

The flats had been closed for almost a week after an historic rainfall on Sept. 30 forced Maine’s Department of Marine Resources to close the entire coast to shellfish harvesting. Even though he knows the closures are a temporary and necessary precaution — until water quality testing determines there’s no longer a risk of runoff pollution contaminating soft shell clams and mussels in the tidal flats — it’s still hard for Sheehan to accept another blank day on his company’s ledgers.

“I’m a dealer, our business depends on clams,” he says.

He’s not alone in that frustration on this bright Tuesday morning. By mid-morning, a dozen or more clammers had sent text messages asking Sheehan if the flats were open yet. Others had pulled up to his seafood warehouse in pickup trucks — some more than once as the sun advanced towards high noon — wondering the same thing.

“Still no word,” Sheehan tells them. Weathered faces nod impassively. They’ve been through this drill before. A full-time clammer, Kittery or Pembroke no difference, is always waiting for something — the tides to change, DMR closures to lift, prices to go up and tiny seed clams to grow to harvestable sizes.

By his own admission, patience doesn’t come easily to Sheehan, who says by nature he’s driven to solve problems. It’s been a hallmark of the wholesale seafood business he and his wife created three years ago, when they realized the scientific specimen business they incorporated in 2002 — whose sales had plummeted with the recession — wasn’t coming back fast enough to keep them in Washington County.

MARYLAND: Down year seen for oysters

October 8, 2015 — Watermen dredging the muddy bottom of the Chesapeake Bay and its tributaries for oysters may not haul in the bounty that some recent years have produced, the Maryland Department of Natural Resources cautions as a new season gets underway.

“We’ve had good harvests the last couple years,” said Chris Judy, the department’s shellfish division director. But “we will no longer enjoy the spotlight on our oysters because other oysters are going to enter the market in a stronger way this year.”

The season kicked off Oct. 1, as it always does, but largely in name only. The same nor’easter that chewed at Delmarva’s beaches and rained out a weekend of activities at the beginning of the month kept most watermen off the water. But they were out in force after the skies cleared.

“It looks like we got the whole state of Maryland working on one bar off Tangier Island,” said Greg Price, a waterman based out of Chance in Somerset County. “I counted 55 boats this morning.”

Those freshly caught oysters are already finding their way into refrigerator cases.

“At first it was a little dreary because of the storm, but we’re booming now,” said Miranda Taylor, manager of Ocean Highway Seafood and Produce in Pocomoke City.
