Ocean Acidification Threatens Our Shellfish

February 2, 2018 — The Massachusetts legislature is current considering a number of bills regarding ocean acidification. If passed into law, the bills will establish a special commission or task force to study the effects of coastal and ocean acidification on coastal communities, fishing and aquaculture industries, and local commercially-harvested species. These bills come at a very critical time when what we do or don’t do next to address the effects of ocean acidification could very well alter the Commonwealth’s culture and economy.

What is ocean acidification?

Excess carbon dioxide in our atmosphere from the burning of fossil fuels is driving climate change and along for the ride is increased global temperatures, rising sea levels, and increased storm intensity. We hear about it almost daily. But on a planet that’s 70 percent ocean, what’s happening below the waves? They call it global warming’s evil twin: ocean acidification.

Much like the atmosphere, the ocean is absorbing more and more carbon dioxide. As a result, ocean temperatures are not only rising, but the actual chemistry of the ocean is changing. Research estimates that the ocean has become 30 percent more acidic since the Industrial Revolution. In particular, the Gulf of Maine is especially vulnerable because its colder waters can absorb more carbon dioxide than other ocean areas. Massachusetts’ bays and sounds are among those waters impacted by ocean acidification.

Why do we need to act?

Ocean acidification should be very alarming to Massachusetts and its legislators because it poses a grave threat to the Commonwealth’s shellfish fisheries – the most valuable in the Commonwealth. Increased ocean acidity interferes with the ability of shell-forming organisms such as clams, mussels, and oysters to build and maintain their calcium carbonate shells. The planktonic larval stages of many species are also vulnerable, a concern for hatcheries and wild populations of shellfish.

RHODE ISLAND: Sewer Line Break Forces Suspension of Shellfish Harvesting

Mount Hope Bay and a river flowing into the bay are closed to shellfish harvesting because of a sewer line break and overflow.

January 31, 2018 — PROVIDENCE, R.I. — Mount Hope Bay and a river flowing into the bay are closed to shellfish harvesting because of a sewer line break and overflow.

The Rhode Island Department of Environmental Management said Tuesday that Mount Hope Bay and the Kickemuit River will reopen Feb. 15, pending the outcome of tests for fecal coliform bacteria. The Massachusetts Division of Marine Fisheries closed Mount Hope Bay in Massachusetts.

The Bristol County Water Authority made emergency repairs to a water main near a sewer line on Jan. 5.

Maine plans swifter protocols for shellfish monitoring

November 13, 2017 — No one knows the origin of an algae bloom that closed hundreds of miles of Maine coastline to shellfish harvesting this fall. Or why the microscopic phytoplankton responsible for it suddenly became so bountiful in the Gulf of Maine. Or even why it produces toxins in the first place.

What is known is that a toxic bloom of Pseudo-nitzschia, a common phytoplankton, caused a recall of 58,500 pounds of blue mussels in September – only the second shellfish recall in Maine’s modern history. To prevent another recall, the state is drastically reassessing its shellfish monitoring practices.

“I was confident we were going to be ahead of it. We knew a lot more, we were quicker to react to it, but we weren’t accounting for the fact that in less than a week toxins could go from barely detectable to over the (safety) limit.”

Next year, even a hint of toxic Pseudo-nitzschia in the water will trigger broad precautionary closures until the department knows shellfish are safe, an entirely new approach to biotoxin management, Kanwit said.

Aquatic limbo

November 5, 2017 — Fourteen years is a long time.

Consider, in 14 years children go from being unable to do much more than eat, sleep and relieve themselves to walking, talking, and giving serious consideration to driving a car.

Fourteen years is also the length of time of three-and-a-half presidential terms; more than long enough to change the direction of an entire country and the fates of hundreds of millions of people.

Fourteen years is also an interminably long time to wait if your livelihood is at stake. And yet, it took the New England Fisheries Management Council 14 years to develop regulations regarding the protection of fishing habitats. That, in and of itself, would not be so bad; after all, one would hope that those involved would take the time necessary to get the science right on an issue where so much is at stake.

But it has now been two years since those regulations were passed, and there is little indication that they are any closer to being implemented.

NOAA Awards $1.7M For Harmful Algal Bloom Research To Protect Public Health From Toxins In Shellfish

Multi-year awards to focus on bloom prevention in seven states

September 20, 2017 — NOAA has announced nine research grants will go to organizations around the country seeking to better understand and measure the toxicity of harmful algal blooms, known as HABs.

In the first year, $1.68M will fund research for projects in Alaska, California, Florida, Maine, Maryland, Ohio and Virginia. The grants are administered by NOAA’s National Centers for Coastal Ocean Science.

Grant recipients will conduct research to identify conditions that increase a bloom’s toxicity; model toxin movement from the water into shellfish, fish and marine mammals; and improve toxin monitoring and forecasts. The dense scum, strong odors and toxins produced by HABs can contaminate drinking water, trigger fisheries closures and disrupt tourism.

Algae bloom forces suspension of shellfishing in parts of Down East Maine

It’s the second straight year that a bloom of Pseudo-nitzschia, a phytoplankton that can carry toxic domoic acid, has forced a closure along large parts of the coast.

September 15, 2017 — A marine algae bloom that can carry a potentially deadly neurotoxin has forced the suspension of shellfish harvesting in parts of Down East Maine.

The state Department of Marine Resources reported Thursday that it was monitoring an active bloom of Pseudo-nitzschia, an ocean phytoplankton that carries domoic acid, a toxin that can cause sickness, memory loss and brain damage in humans. It’s the second year in a row that a toxic Pseudo-nitzschia bloom has halted harvesting of mussels, clams and oysters along large parts of the coast.

Before 2016, there was no record of a toxic bloom of this type in the Gulf of Maine.

The department’s public health section found levels of domoic acid that exceeded health standards in shellfish tested between Mount Desert Island and Gouldsboro. That area has been closed to harvesting and the department enacted a precautionary closure from Deer Isle to Machiasport, almost a third of Maine’s coastline.

Department spokesman Jeff Nichols said officials were monitoring the situation closely. There is no indication that contaminated shellfish have made their way to consumers, he said.

“It is impossible to determine at this point if the concentrations of domoic acid will increase in other areas,” Nichols said. “But we know that the phytoplankton that produces it grows rapidly, so we are carefully monitoring the entire coast and will be able to rapidly detect harmful levels of domoic acid and take action to protect the health of Maine’s shellfish consumers.”

A Bacteria That Thrives In Warmer Waters Keeps Mass. Oyster Fisheries On High Alert

August 31, 2017 — Massachusetts loves its local oysters from places like Wellfleet and Duxbury. The state’s bivalve business is booming along with increased consumer demand. These days there’s no shortage of $1 oyster specials and oyster-centric restaurants around here.

But the ways oysters are harvested and handled have become more involved and challenging since 2013. That’s when bacteria linked to warming waters appeared in our marshes for the first time.

The result was an outbreak of gastrointestinal illness caused by Vibrio Parahaemolyticus — Vp or Vibrio for short. (To be clear, this is different from norovirus, which led to a closure of shellfish beds in Wellfleet last year.)

In response to the Vp bacteria’s emergence in New England, the state implemented a Vibrio Control Plan. Here’s how those state efforts to control bacterial infection have been affecting people in the oyster industry.

‘The Waters Are Warmer Than They Used To Be’

At Select Oyster Bar in Boston, you can find a rotating selection of Massachusetts oysters on-the-half-shell — Moon Shoal petites from Kingston, Ichabods from Plymouth and Wellfleet Puffers.

For about a dozen years Select’s chef-owner Michael Serpa has been serving mollusks in Boston establishments, including the cult-favorite Neptune Oysters in the North End. “I’ve seen a lot of oysters,” he told me, smiling.

MASSACHUSETTS: Cape Cod shellfish bed closures await lab results

July 10, 2017 — Shellfish growing areas in six towns that were closed by the state Division of Marine Fisheries on Friday remained closed Monday pending lab results of bacteriological water samples from the affected areas, according to Katie Gronendyke, spokeswoman for the state Office of Energy and Environmental Affairs.

The state closed shellfish growing areas east of the Cape Cod Canal in the towns of Sandwich, Bourne, Falmouth, Mashpee, Barnstable and in Lewis Bay in Yarmouth because of extreme rainfall. Shellfish beds in Sandwich are open only from November through May, according to the Sandwich Department of Natural Resources.

Friday’s rain, which accumulated up to 4 inches in two to three hours in some areas, overwhelmed roads, parking lots and storm drain systems, Gronendyke wrote in an email. The flooding can cause contaminated water to accumulate and release into coastal waters, she wrote.

The towns in which the shellfish growing areas were closed received the heaviest rainfall, she wrote.

Driven By Lobster, Value of Maine Fisheries Landings Rises

May 10, 2017 — Landings of finfish and shellfish in Maine accounted for over $588 million in revenue in 2015, the most recent year for which statistics are available, and more than 39,000 jobs, according to numbers released Tuesday by NOAA Fisheries.

The total landings in Maine for 2015 were up more than $40 million compared to 2014 and up more than $112 million compared to 2013.

Rita Curtis, a NOAA Fisheries division chief for economics and social analysis, says American lobsters drive Maine fisheries.

“Maine lobster was up again, about $40 million. Prices were up we’ll say about 10 percent, more or less. Soft shell clams were up,” she says.

Curtis says, across the board, there was a lot of good news for Maine.
