Reef restoration projects aim to bolster Texas’ record-low oyster population

November 16, 2018 — With oyster populations in Texas at historic lows, The Nature Conservancy is launching two new reef restoration projects that look to appease commercial fishermen and environmentalists alike.

Using funds from the Deepwater Horizon oil spill settlement, the group plans to develop 110 acres of reef in Galveston Bay and Copano Bay, near Rockport. Half of each reef will be designated as a marine sanctuary where the molluscs — which have significant economic and environmental benefits — may grow. The other half will be open for commercial fishing.

Construction of the new reefs is expected to begin this winter, with harvestable portions ready as soon as 2021.

Laura Huffman, regional director of The Nature Conservancy in Texas, said these projects show a new approach to oyster reef restoration, with the compatibility of building harvestable reefs at the same time as growing a healthy habitat.

Could Oysters Ease Trade Tensions With U.S.? European Leaders Hope So

November 14, 2018 — BRUSSELS — The United States and Europe may one day put aside their differences on trade, eliminate tariffs on industrial goods and work together to rein in their common economic adversary, China.

But for Cecilia Malmstrom, the European trade commissioner, the most urgent task is to produce quick results, however humble, that will keep an impatient President Trump from imposing even more drastic penalties on European imports than the tariffs his administration has already levied.

So when Ms. Malmstrom meets in Washington on Wednesday with her American counterpart, Robert E. Lighthizer, she will count it as a substantial victory if she can lower the barriers hindering one bit of trans-Atlantic commerce: oysters.

The United States and Europe have long banned the importing of each other’s shellfish. But a deal to ease trade on that front has been in the works for several years and could be dressed up by both sides as a success that helps smooth relations with the White House.

Shellfish may seem like an odd focus for negotiators, but exports from the United States are worth about $1.7 billion a year. And international trade in clams, mussels, oysters and scallops — all of which are shipped live by air — is growing.

The emphasis on mollusks also illustrates a strategy that officials in Brussels hope will prevent Mr. Trump from acting on a threat to impose steep tariffs on European cars, a potentially devastating blow to the European economy.

New study: Chesapeake oyster decline not due to overfishing

November 14, 2018 — Warmer winters, rather than overharvesting, caused the steep decline of oysters and other commercially valuable shellfish in the Chesapeake Bay and elsewhere along the Atlantic coast, according to a controversial new study that’s getting pushback from some scientists.

The study, which appeared in Marine Fisheries Review, a quarterly journal of the National Oceanic and Atmospheric Administration, says that multi-year stretches of mild temperatures in normally weather months altered the food web in coastal waters. That impaired the growth and reproduction of oysters, quahogs, soft-shell clams and scallops, scientists said. It also led to increased predation on shellfish larvae and outbreaks of diseases.

“The temperatures got warm and that changed the whole environment, so [the oyster diseases] MSX and Dermo could flourish,” said Clyde MacKenzie, Jr., the study’s lead author and a longtime researcher at NOAA’s Northeast Fisheries Science Center at Sandy Hook, NJ. Mitchell Tarnowski, who runs the annual fall oyster survey for Maryland’s Department of Natural Resources, is the co-author.

The paper’s conclusions, especially its dismissal of overfishing as a factor in Chesapeake oyster declines, came under fire from scientists with the University of Maryland Center for Environmental Science and Chesapeake Bay Foundation. Its publication comes as the DNR prepares to release a first-ever stock assessment of the oyster population in the Upper Chesapeake, including an evaluation of whether current harvest levels are sustainable.

The scientific consensus has long been that overharvesting, disease and habitat loss over the decades devastated the Bay’s oyster population, with some estimates putting it in recent years at 1 percent or less of historic levels of abundance. From an annual commercial harvest of nearly 17 million bushels in 1880, landings have trended downward, hitting historic lows in 2003-04 of just 50,000 bushels. The harvest has rebounded some since then, though much of the gain has come via private oyster farming, especially in Virginia.

Researchers identify causes of decline in shellfish harvests

November 5, 2018 — NOAA researchers studying the 85 percent decline between 1980 and 2010 of the four most commercially-important bivalve mollusks — eastern oysters, northern quahogs, softshell clams, and northern bay scallops — have identified the causes.

Along with the sharp decline in commercially important bivalves, there has been a corresponding decline in the numbers of fishermen (89 percent) who harvested the bivalves, said researchers with NOAA’s National Marine Fisheries Service.

The bivalve declines are in contrast to the previous three decades (1950–80) when the combined landings of the same bivalves were much higher and the trend in each of their annual landings was nearly level, decade by decade.

The only exceptions to the declines were seen in the harvest of northern quahogs in Connecticut and American lobsters in Maine. However, the numbers of American lobster landings have fallen precipitously – as much as 98 percent – from southern Massachusetts to New Jersey.

The researchers also found during the course of the study that a number of groups of marine and land animals have also experienced large shifts in abundance since the early 1980’s.

Brad Warren & Julia Sanders: Washington’s Initiative 1631 will help fight ocean acidification

November 2, 2018 — We write today to announce our support for Washington’s Initiative 1631. As businesses who rely on healthy fisheries for a significant portion of our income, we believe this is a well-designed policy that offers us – and our customers – the best possible chance against an uncertain future fraught with the threats of changing ocean conditions.

It’s become clear that our fisheries need a lifeline. Here in Washington, we are experiencing the worst ocean acidification anywhere in the world. Research has firmly established the cause of this problem: emissions from burning coal, oil and gas mix into the ocean, altering its chemistry. The consequences loomed into headlines a decade ago when the oyster industry lost millions and nearly went out of business during the oyster seed crisis. Temporary and limited adaptation measures in hatcheries are keeping them in business, but in the rest of the oceans, fisheries that put dinner on billions of tables are at risk. Here in the Northwest, harvests are already being eroded and even shut down by the effects of unchecked carbon emissions.

The “warm blob,” an unprecedented marine heatwave off the West Coast, reached its height in 2015 and caused mass fatalities. In the Columbia River, a quarter-million salmon died. The largest recorded toxic algae bloom shut down the Dungeness crab fishery for months. The food web crashed, and marine creatures were spotted farther north than ever before. Sea surface temperatures never returned to their previous norm, and new research indicates another blob is forming.

Summers have become synonymous with a smoky haze from wildfires causing poor visibility and poor health – this summer the National Weather Service warned even healthy adults in some Washington areas to stay indoors due to hazardous air quality. At the same time, our iconic orca whales are starving from a lack of Chinook salmon. The Chinook in turn are suffering from a lack of the zooplankton that juveniles eat.

Research has made it clear that some of our most lucrative fisheries are vulnerable to ocean acidification: king crab, Dungeness crab, and salmon. Scientists also warm that combining stressors – like warming with ocean acidification – makes survival in the ocean all the more precarious.

Some North Carolina seafood unsafe to eat after Hurricane Florence

October 26, 2018 — Some seafood caught in North Carolina may not be safe to eat in the aftermath of Hurricane Florence.

Florence made landfall in Wrightsville Beach on Sept. 14. It was a Category 1 storm at landfall, and the storm moved extremely slowly–dumping dozens of inches of rain on many parts of North Carolina.

Florence dumped 8 trillion gallons of water on North Carolina. That’s enough to fill Falls Lake more than 70 times.

The influx of water turned creeks and streams into whitewater rapids that picked up everything in their paths.

The polluted runoff spilled into the Cape Fear River and Neuse River, then into the Pamlico Sound, and finally into the Atlantic Ocean.

The runoff forced North Carolina’s Department of Marine Fisheries to order a blanket ban on harvesting any shellfish off the coast. Months after the storm, miles of coastline remain off limits.

Wildlife most vulnerable to the pollution are filter feeders like clams, mussels and oysters.

Omega 3 fatty acids found in seafood tied to healthy aging

October 24, 2018 — People may be more likely to age without health problems when they have more omega 3 fatty acids in their blood, a recent study suggests.

The study authors focused on so-called healthy aging, or the number of years people live without developing disabilities or physical or mental health problems. They examined data on 2,622 adults who were 74 years old on average, following them from 1992 to 2015. Only 11 percent of participants experienced healthy aging throughout the entire study period.

“We found that older adults who had higher levels of omega 3 from seafood were more likely to live longer and healthier lives,” said lead study author Heidi Lai of the Friedman School of Nutrition Science and Policy at Tufts University in Boston.

“These findings support current national dietary guidelines to consume more seafood,” Lai said by email.

Adults should get about eight ounces a week of seafood, ideally by eating it twice a week in place of meats, poultry or eggs, according to U.S. dietary guidelines. Some options that are high in omega 3s include salmon, anchovies, herring, shad, sardines, oysters, trout and Atlantic or Pacific mackerel.

‘Aquaculture’s Next Wave’ Explores How Maine Entrepreneurs Are Navigating Changing Seas

October 2, 2018 — This week we’re taking a deep dive into aquaculture and its potential to add real value to the state’s coastal economies. In “Aquaculture’s Next Wave” we will meet the innovators who are trying to take seafood farming to a new level in Maine.

Worldwide, aquaculture now provides more than half the world’s seafood. Yet here in the U.S. and in Maine, it’s far behind wild caught harvest. At the same time, we in the U.S. import roughly 90 percent of our seafood. For some investors and entrepreneurs, including Maine lobstermen, that spells opportunity.

Maine Public reporter Fred Bever spoke with Morning Edition host Irwin Gratz about aggressive exploration of new technologies and new markets for farmed seafood.

Gratz: Why is aquaculture important right now?

Bever: It’s because marine ecosystems and economies are being disrupted. Actively farming fish, shellfish, even seaweed — that can be a hedge against disruption and, long term, maybe the most profitable response. There’s a growing set of Maine visionaries who are pursuing that.

The planet’s oceans are always in flux and wild harvests have long been vulnerable to natural variation and overfishing, right?

Yes, but with the oceans warming, the dynamics are accelerating, and that’s nowhere more true than in the Gulf of Maine.

Scientists say the Gulf is warming faster than 99 percent of the world’s oceans, correct?

That’s almost a truism now. We’ve seen epic disruptions in recent decades — the crash of cod, fisheries for marine shrimp, for urchin and now herring are all restricted, lobster populations are making a slow march ever north and east following the warming trends.

Plans for second-largest oyster farm in US state of Maine runs into resistance

September 27, 2018 — An effort to launch what would be the second-largest oyster farm in the US state of Maine is running into some resistance, the Portland Press Herald reports.

Doug Niven and Dan Devereaux, owners of The Mere Point Oyster Co., in Brunswick, have planned a 40-acre oyster farm in Maquoit Bay, consolidating 26 aquaculture licenses to produce about 5 million oysters annually.

The bay is about 3,000 acres and the Maine Department of Marine Resources limit for aquaculture farms is 100 acres. A site review shows the farm unlikely to affect boat traffic or hinder lobster harvesters and bait fishermen.

But some residents, calling themselves the Maquoit Preservation Group, attended a meeting of the Brunswick Town Council last week to voice concerns about the proposal, including especially the impact on the environment and the amount of noise produced by the oyster tumbler. One resident compared the oyster sorting machine to having a cement mixer on the water. They say they were surprised to learn of the size of the farm, as most other oyster farms in the area are just five to 10 acres.

Residents alarmed by proposed expansion of Maine shellfish farm

September 17, 2018 — ELIOT, Maine — Frustrated residents from the Eliot and Kittery sides of Spinney Creek appeared before the Select Board Thursday night, seeking recourse about their concerns of the proposed expansion of Spinney Creek Shellfish.

Spinney Creek Shellfish, at 27 Howell Drive in Eliot, is applying to the Maine Department of Marine Resources to obtain a three-year aquaculture lease on 3.67 acres of Spinney Creek, a salt pond between Eliot and Kittery off the Piscataqua River. The new lease is for raising oysters and littleneck clams (quahogs) in suspended cages.

The residents have discovered Eliot and Kittery’s boards have no control over aquaculture in the pond.

Roberta Place of Spring Lane on Spinney Creek said residents of 50 households bordering the creek are concerned about the creek’s health.

“I have lived there a long time. I used to swim there with a wet suit. Now the temperature in the creek is 74 degrees,” she said.

She said she thought oysters are supposed to clean water, but added that the eelgrass in front of house has disappeared.
