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.

Ocean acidification poses threat to lobsters

December 18, 2015 — PROVIDENCE — Lobsters are already slowly moving out of southern New England as waters warm, but the iconic crustacean faces another future threat as the climate changes.

As oceans absorb more carbon and become increasingly acidic, juvenile lobsters likely will have a harder time growing and forming strong shells to protect them from predators, according to a recent University of Rhode Island study.

“I’m not sure yet what the mechanism is that is affecting their growth,” URI doctoral student Erin McLean, who led the research, said. “But it takes energy for them to regulate the increased acidity, which is energy they cannot then put toward growth.”

And it’s not just lobsters that could be harmed by the oceans’ changing pH levels. Shellfish populations in Rhode Island and Massachusetts in general are among the most vulnerable in the United States to ocean acidification, according to a recent study in the journal Nature Climate Change.

The study identified the two states among 15 at-risk areas in the nation because colder, northern waters, such as Narragansett Bay, Buzzards Bay and Nantucket Sound, are absorbing more carbon dioxide from the atmosphere and acidifying faster than warmer waters.

Other more localized factors are also playing a part, including nutrient pollution from fertilizers and sewage systems that can add more carbon to the water and the flow of fresh water from poorly buffered rivers, such as the Blackstone in Rhode Island or the many waterways that drain into the Gulf of Maine, which lack minerals to mitigate the effects of acid. Shallow coastal waters also are more susceptible to changes in the ocean’s chemistry.

About a quarter of all carbon emissions from power plants, cars and other sources are absorbed by the oceans, making them more acidic and reducing carbonate levels. Shellfish use carbonates to make their shells, and when fewer of the compounds are available, organisms must expend more energy to build shells and less on eating and survival, researchers say.

MASSACHUSETTS: Would-be mussel farmers fishing for project money

December 14, 2015 — The aquaculture project Salem State University marine research scientists hope might ultimately produce acres of mussels in a stretch of deep, open waters off the coast of Cape Ann has received the necessary permits to proceed.

Now all the project managers need is … what else? Money.

Mark R. Fregeau, a SSU marine biology professor, said the project he is managing with SSU colleague and collaborator Ted Maney has been green-lighted by the U.S. Army Corps of Engineers and will begin in earnest once they raise about $75,000 needed to begin laying the initial long lines upon which the mussels will grow.

The mussel aquaculture — or more simply, farm — will be located in federal waters, about 81/2 miles due east of Good Harbor Beach, at a site the researchers believe will provide the perfect environment for a deep-water mussel aquaculture that would be the first of its kind in the U.S.

“We’ve been authorized to put out a couple of (experimental) lines and see how they work and what issues might arise,” Fregeau said. “The reality is that until we actually get into the water, we don’t know exactly what we’ll be dealing with. So, it will be rolled out in phases, a couple lines at a time, and that will give us the opportunity to report back to the Army Corps of Engineers and NOAA.”

MASSACHUSETTS: Chatham, state officials contest federal right to control fishery

December 9, 2015 — CHATHAM — The state, town and federal governments are fighting over ownership of the ocean within the Monomoy National Wildlife Refuge.

Unless something changes dramatically in the next few months, a court will have to decide who can manage fisheries in the area, according to Chatham officials and Massachusetts Attorney General Maura Healey.

The U.S. Fish and Wildlife Service claimed ownership and management of the 3,000 acres of water and ocean bottom west of North and South Monomoy islands in its final draft of a new plan meant to guide management of the wildlife refuge for the next decade or more. The comment period on the draft expired Monday and the state attorney general’s office, the state Department of Fish and Game, and the town of Chatham all filed comments, along with an additional two dozen or more letters and emails submitted as of early Monday, according to Elizabeth Herland, Fish and Wildlife project director.

In the comments, the town and attorney general disputed the service’s claim that it was granted ownership and control over the disputed area in a 1944 court decision that established the refuge through a land taking. In her comments, Healey called the assertion erroneous and threatened legal action unless the federal agency revises its stance.

The town is also contemplating legal action, said Jeffrey Dykens, chairman of the selectmen.

“We would like to avoid litigation but we are keeping all our options open,” Dykens said.
