An Overview of the Demise of Rhode Island's Oyster Industry and its Cause... The Toilet???

We recently came across this terrific and insightful presentation by Michael Rice of the Rhode Island SeaGrant. The economic overview is very thought provoking. 


In 1910 oyster protein cost 1/3 of that of eggs. while today it is roughly 6 times as costly. What drove this change? Well one interesting factor appears to be the dramatic decrease in supply.



In 1910 Rhode Island had 21,000 acres of oyster farms. (No  we are not off by a zero.) The hardy creatures could be shipped without refrigeration and the industry threw off the modern day equivalent of half a billion dollars into the State's economy.  



Today RI's oyster aquaculture is down to 172 acres. In 2012 direct oyster sales were under $3 million and the economic impact was less than $15 million. This means there is a huge economic opportunity here. 



But what drove the fall off in oyster production? This is where it gets really interesting. In 1901 John Crapper began promoting the siphon toilet that was actually invented by John Harrington.

With the influx of indoor plumbing driven and the growing use of toilets, the amount of liquid waste grew dramatically. This in turn led to the expansion of the sewer systems in the 1910-20 period, which led to increased waste disposal in the Narragansett Bay. While this solved the sanitation problem in the cities, it led to problems with oyster safety. The deaths of several prominent people drove the development of the National Shellfish Sanitation program in 1925. 


With pollution already taking its toll on the available area, the Hurricane of 1938 hit many hard and then came the labor shortages of World War 2.  These labor shortages were significant. The trees we see along many golf courses today began growing in as there was less manpower to tend the courses and they focused on the actual holes. The last oyster farm closed in 1952 and the field did not restart until 1995.

Wine Designed for Pairing with Oysters Supports Oyster Restoration

The team at Proud Pour has developed a Sauvignon Blanc wine specifically to be paired with oysters. Founder Kim Kelly was frequently torn between allocating time to happy hour and working on environmental causes.

Oysters Could Help Protect New York from Sea Level Rise

This article is reprinted and excerpted from a Michael Kane article in the New York Post. You can find the original article here. 

Why New York should become the city of oysters again




“Our raw-bar special tonight is the Gowanus oyster. Briny, good salinity with undertones of sewage and industrial detergents . . .”
Hard to imagine now, but New York Harbor and its surrounding tributaries, estuaries and bays once produced enough native shellfish that a typical city dweller ate about 600 local oysters a year.
Cheap, abundant oysters were the pizza slice of the early 1800s. For less than a penny apiece, this poor man’s dietary staple was sold at countless oyster saloons in lower Manhattan. The happy-hour special — called the “Canal Street Plan” — was all-you-can-eat for a sixpence.

Pearl Street — called Parelstraat by Dutch colonists — was so named because the road was paved with native oyster shells.
By 1910, 1.4 billion oysters a year were pulled out of city waters — and, around the same time, the people eating all those increasingly bacteria-tainted shellfish began to fall ill with vibrio cholera and typhoid.
As recently as 1921, lobsters and shellfish were still being plucked from Jamaica Bay in Queens — not so appetizing now that the bay is home to JFK Airport and four sewage-treatment plants.
There are still some surviving oysters in Big Apple waters, such as the practically pitiable Crassostrea virginica, but as oysters are, in essence, a creature of water filtration, they are not surprisingly polluted, diseased and mercifully few. Any oyster you see on a raw-bar menu in the city these days comes from at least 30 miles away. Anywhere from Rhode Island or Maine to the Pacific Northwest.
It’s a bit ironic amid a locavore movement among the city’s foodies that New York has such “a broken relationship with its own ocean,” says author Paul Greenberg.
Two centuries ago, reefs composed of 3 trillion oysters were a “natural seawall” that created shallower bays and served as a “first line of defense for Manhattan against storms as fierce or fiercer than 2012’s Hurricane Sandy,” Greenberg writes.In “American Catch,” eco warrior Greenberg laments the “pollution free-for-all” that killed the edible New York City oyster (“By 1910, 600 million gallons a day of raw sewage were going into New York’s waterways”), yet he remains hopeful of a rebirth for the most unlikely of reasons: flood control.
Over the next 50 years, the sea level is predicted by environmental scientists to rise approximately two feet. Since Sandy, the Army Corps of Engineers, architects and federal and city government officials have been brainstorming ideas to head off the next catastrophe. Proposals have included building a massive, 5-mile seawall hook or elevated platforms ringing the Battery.
Greenberg posits that a far more effective and certainly more cost-effective — less than $1 billion compared with estimates of around $50 billion for the more outlandish ideas — would be to repopulate oyster beds around the city. It’s an idea already studied by the organization NY/NJ Baykeeper, which is headquartered on Governors Island.
Not surprisingly, a component of the plan is recycling. Think of all those tons of oyster shells thrown into the trash by city restaurants every year. Those could be reintroduced to the water to serve as a base for a revitalized oyster bed. Additionally, concrete when coated with calcium carbonate acts as a fertile base for oyster larvae to set.Oysters are unique among shellfish in that they build their beds vertically — upon the shells of expired ancestors — almost like coral reefs. With pollution greatly reduced since the 1972 federal Clean Water Act, the author believes that with a jump-start, oyster reefs could become self-perpetuating over the next century.
Greenberg admits oysters alone “wouldn’t stop the inundation” of a massive hurricane, but it could “mitigate its extremes.”
“An oyster reef could, for example, extend the breakwater at Breezy Point at the far end of the Rockaways and shield Coney Island in its lee,” he writes. “The ocean is coming at us in a way it never has before, and very soon we will be forced to profoundly renegotiate a truce between land and sea.”
OK, so when do we get to eat a New York City oyster?
“Sometime around 2050,” Greenberg says.
“Gotham is in fact one huge estuary,” he adds. “Once upon a time, each little outflow had its own salinity and its own specific oyster taste. Today most of the creeks have been interrupted, paved over, and rerouted underground, through the sewer system or trickling out along subway lines.”

Subway oysters? Might want to have the cocktail sauce ready

New Hampshire Oyster Restoration Successfully Putting Federal Dollars to Work

This article is excerpted an article by Crystal Weyers from Seacoast Online. You can see the original article here. The Great Bay is an enormous and underknown estuary near Portsmouth, New Hampshire. Here is a link to The Great Bay Stewards.



Restoration effort of Great Bay making 'measurable progress'

PORTSMOUTH — The effort to restore reefs of live oysters to the Great Bay estuary is in it's sixth year and making measurable progress.

With 15.5 acres of reef constructed and more than 13 million adult oysters restored to the estuary already, the effort is the largest of its kind north of Chesapeake Bay.
“We're a little ahead of schedule,” said the Conservancy's director of external affairs, Jim O'Brien.The Nature Conservancy and its partners at the University of New Hampshire have been busy attempting to restore the “once abundant shellfish to a natural system stressed from a number of factors including loss of habitat and increased nitrogen levels.”
This summer's reef restoration, in the bay near Newmarket, was completed Wednesday. O'Brien said the population first collapsed in the 1990s when a waterborne disease made its way up the coast from the southern states.
“It really decimated the population,” he said. “It wiped out the vast majority, (90 percent), of the reefs.”
The oysters now being introduced are special disease-resistant oysters raised at a UNH laboratory by Dr. Ray Grizzle. The group is hoping these oysters will grow a more resilient population.
The shellfish play an integral role in sustaining the estuary and filtering harmful pollutants out of the water. O'Brien said the creatures offer three benefits: providing a physical reef structure, which acts as a physical barrier in the water column to help prevent erosion; serving as a habitat for many species of fish and eel grass; and filtering nitrogen and other pollutants.
“Oysters are water filters,” he said, explaining one oyster can filter as many as 20 gallons of water each day on its own. With Great Bay suffering from increased nitrogen levels, oysters provide a natural solution.
“The more oysters, the more filtering of nitrogen they do and the less nitrogen in the water,” O'Brien said, adding the reefs are built near wastewater treatment plants that are already closed off to harvest. 
It is interesting that New Hampshire has found ways to place oysters in closed waters while those in Massachusetts remain inflexible on this point.
Although the group has worked to construct acres of reefs the past several years, O'Brien said the goal is for the oysters and the reefs to eventually become self-sustaining. The reefs are built by laying several hundred tons of dried, recycled surf clam shell to the estuary channel bottom in arranged plots. The shell layer acts as the foundation for the living reefs, which then act as “spawner sanctuaries” for the rest of the estuary.
“The restoration of oysters may be Great Bay's best hope for a sustainable recovery of the estuary” said Dr. Ray Konisky, the conservancy's director of marine science. “These resilient animals are amazing natural water filters — with mature reefs having the ability to naturally remove tons of nitrogen annually from the system. We feel strongly that oyster restoration is a natural solution that will help bring the Bay back into balance.”
The scientists' goal is to restore 100 acres by “ramping up” their efforts in the next few years. Konisky believes the reefs will offer “dramatic, long-term benefits for the natural system” and are simply “a common sense solution that will assist our communities in meeting their nitrogen reduction goals.”
The newest reefs were constructed earlier this week by marine scientists from the Nature Conservancy and UNH alongside local marine contractors Riverside & Pickering and Granite State Minerals. Later this summer, more than a half-million of Grizzle's lab-raised oysters will be placed on the newly constructed reef. The reef will be monitored to measure oyster growth, habitat restoration and overall reef success.
Funding for the project comes from federal, state, and private sources. Lead funders include the Piscataqua Region Estuaries Partnership, National Oceanic and Atmospheric Administration Restoration Center, N.H. Department of Environmental Services and many private donors.
