Ocean Gate, N.J. (AP) — Restoring oyster beds and helping keep the water clean isn’t just for scientists and environmental groups anymore.
Students, younger children and those with no particular scientific background like the idea that something they do this morning can be helping the earth by this afternoon.
Kenna Allocco, 12, of Beachwood, New Jersey, recently helped remove bags of whelk shells with baby oysters attached to them from a bubbling tank in preparation for their journey to a Barnegat Bay reef, in between asking a dozen or so incisive questions of program leaders.
“I’m interested in how all the animal species interact with each other, and in biodiversity,” she said. “We’re learning about this in school. I made a speech about the problem of plastic pollution in the ocean, and I scared my entire class. None of them uses plastic straws anymore.”
The efforts are part of a worldwide effort by scientists and volunteer environmentalists to dump millions of baby oysters into waterways where they once thrived before overharvesting and pollution virtually wiped out the shellfish.
In addition to helping improve water quality and stabilize shorelines against strong storms, many people involved in the oyster seeding projects say one of their best benefits is providing an immediate, easy way for people to get involved and help the environment.
“It’s a very real, tangible, physical thing you can do and see that it is helpful to the environment,” said Zack Royle, a habitat restoration coordinator with the American Littoral Society, a New Jersey coastal environmental group. “You place the seed oysters in the tank, you watch them grow and you put them into action when you dump them overboard.”
The New York/New Jersey Baykeeper group is adding to an artificial reef it has built for oysters along the shoreline of the Earle Naval Weapons Station in Middletown, where the shoreline was ripped up by Superstorm Sandy in 2012.
Meredith Comi, restoration director for Baykeeper, said the baby oysters attach themselves to the rows of concrete castles the group dumped a few hundred feet from shore. As the shells grow, they expand the mass and shape of the reef, providing “speed bumps against wave action during storms,” she said.
A Baykeeper project in mid-July placed a million young oysters near the heavily guarded Navy pier. Over the past 10 years, they’ve set out 4 million of them in various spots.
Since it built the base of an oyster reef using empty whelk shells in Ocean Gate, New Jersey, in 2015, the Littoral Society has placed 6.3 million oysters on those shells, estimating that about 207,000 remain alive and growing.
At least 70 million more could be planted in the next few years, said Capt. Al Modjeski, an official with the Littoral Society.
Once they reach the water, the oysters have about a 10 percent survival rate, scientists say.
Oyster restoration projects are underway or have recently been completed in San Francisco Bay; Puget Sound near Seattle; in coastal salt ponds in Rhode Island and the state’s Narragansett Bay; in the Carolinas; in Florida and the other Gulf Coast states; in New Hampshire; and particularly in Chesapeake Bay in Maryland and Virginia, where some of the nation’s biggest oyster restoration programs have been underway for years.
Since launching in 2014, an effort to restore oysters in New York Harbor called the Billion Oyster Project has planted over 28 million oysters, with the goal of reaching a billion by 2035.
In Europe, oyster restoration projects are being done in England, Scotland, Ireland, France, the Netherlands, Germany and Sweden.
The work usually involves scientific groups setting up tanks in which to cultivate baby oysters. Then they turn to volunteers to help put them into waterways.
“A really important part of this work is connecting people back to the environment,” said Tim Dillingham, executive director of the Littoral Society. “This gives them an opportunity to become citizen-scientists and actually participate in oyster restoration.”
