Millions of pounds of oyster shells are being recycled to help restore the Louisiana coast


One night in March, Jason Pitre left his Bayou Rosa Oyster Farm in Leeville with sacks of oysters bound for a fundraiser in New Orleans. He’d just pulled those oysters from the waters of Bayou Lafourche, the same his family has worked for four generations.

As he opened each oyster, he knew that eventually their shells would be headed back to the coastal again.

The shells were collected during the event and fed into a stream of oyster shells, measured in the millions of pounds, that will be used to restore Louisiana oyster reefs. That’s helping cultivate more oysters, boosting ecosystems around them and contributing to coastal restoration efforts.

“I know the effect these reefs have on our living shoreline,” said Pitre, a member of the United Houma Nation who counts oyster farming as part of his heritage. “It’s rewarding to know that what I grow will go back into the water to help the coastal restoration fight that we’re in. It’s this whole circle of life being completed.”

Pitre was one of a half dozen oyster farmers serving samples of their harvests at Shell-a-Bration, the annual fundraiser held at Audubon Zoo for the Oyster Shell Recycling Program. The initiative is part of the Coalition to Restore Coastal Louisiana, a New Orleans-based nonprofit that advocates to protect the state’s coast.

The Oyster Shell Recycling Program works with restaurants to collect oyster shells that would otherwise be headed to the landfill and puts them back to work for the coast.

Restoring the loop

The shells become the building blocks for reef restoration projects, and the coalition has been working specifically with indigenous communities, selecting project areas where they can help protect sites of special cultural and environmental significance.

The program is 10 years old, but the idea is not a new one.

“It’s filling a gap in a process of returning shells to the wild, a process that’s been around since people started eating oysters, because people always knew they provide habitat for more oysters,” said Darrah Bach, recycling program manager for the coalition.

But without direct connections to oyster lease holders, most restaurants simply throw shells in the trash like all the other kitchen waste.

“We’re restoring that loop, giving restaurants a way to get shell back to where it can do the most good,” she added.

Oyster reefs beget more oysters. Baby oysters need a platform on which to grow, and the shells of other oysters are ideal for this purpose. As oysters layer up upon oysters, reefs form and grow higher and thicker.

This creates habitat for other sea life, but the benefits of healthy and restored reefs are far reaching. They can serve as buffers between the open water, communities and habitats along the coast. During storms, reefs act as underwater speed bumps, and even in calmer times they break up the wave energy approaching fragile coastal features.

One vivid example is playing out in Plaquemines Parish, in Adams Bay, where the coalition and its partners deployed 150 tons of shells to restore a reef to better protect what’s known as the Lemon Tree Mound.

While the space is an ancient Native American archaeological site, saltwater intrusion and wave action killed its namesake trees and threatened to wipe out the mound. Since the reef restoration began here in 2021, the mound’s grassy footprint has been expanding behind this rampart-like reef.

Expanding the harvest

The Oyster Shell Recycling Program has steered some 14 million pounds of oyster shells back to the coast over 10 years, and the 30 restaurants participating now contribute about 1.5 million pounds a year.

To customers the recycling process is largely invisible, and for restaurants it’s simply a matter of steering shells to bins for recycling collection. Many of the biggest names in the New Orleans oyster scene take part, including Acme Oyster House, Felix’s, Drago’s, Casamento’s and Sidecar.

Dickie Brennan’s Bourbon House in the French Quarter was the first restaurant to sign up for the program, and today, every one of the roughly 2,000 oysters shucked daily at its busy oyster bar join the reef restoration effort. When the same restaurant group acquired historic Pascal’s Manale Restaurant last year, one of the first orders of business was to add its oyster bar to the program also.

Recycling bins at the restaurants are emptied several times a week, and the shells are hauled to a curing site in St. Bernard Parish, where they sit in the sun and open air until they’re ready to deploy.

The program charges restaurants for the service, likening it to any other recycling or waste disposal service.

However, now there’s help available to cover that cost. In January, the state enacted a new tax credit for restaurants that recycle oyster shells, at a rate of $1 per 50 pounds of shells recycled.

“We’re hoping that will be a big motivator for more restaurants to join the program,” Bach said.

The tax credit comes as the coalition is also expanding the geographical reach of its recycling program. Right now, all participating restaurants are in the New Orleans area, but the group wants to add restaurants in Baton Rouge and is now looking for contractors to haul shells. The group is eyeing potential further expansion with restaurants around Lafayette and Houma.

Making connections

Shell collection was temporarily shut down in the early phases of the pandemic, when restaurants were closed. But participation grew as restaurants started coming back, with assistance from one of the coalition’s partners.

Chef’s Brigade is a grassroots group that quickly formed to help keep New Orleans restaurants in business during the bleakest part of the pandemic — and founder Troy Gilbert, an advocate for coastal restoration, connected many of these restaurants with the recycling program along the way.

Today Chef’s Brigade also operates a program called Chefs on Boats, which brings restaurant staff out on boat tours to the front lines of coastal loss and restoration, including to oyster reefs built on recycled shells.

“They’re making that connection between what they’re doing in their restaurants, where it comes from and the good those shells could do again, why it’s worth making the change in their operations,” Bach said.

The effort has also become a recruiting tool for the recycling program, giving a firsthand perspective on the difference restaurants can make through one change in their operations. As more people learn about the oyster shell recycling program, it’s also making that connection between restaurant customers and oyster aficionados.

The Coalition to Restore Coastal Louisiana has public access recycling bins situated around New Orleans, where people who open oysters at home can recycle shells at no charge. The public can support the program through contributions, and there are also hands-on volunteer opportunities with shell bagging events through the year.

“Another way people can support this is just to ask at the restaurants they visit if they recycle,” she said. “That helps build awareness.”

Louisiana considers opening recreational alligator hunting season

Louisiana considers opening recreational alligator hunting season


play

  • Louisiana lawmakers are considering a bill to create a recreational alligator hunting season.
  • The proposed season would be open to 5,000 lottery-selected hunters annually, with a two-gator limit.
  • Louisiana’s wild alligator population has grown to over 2 million, a significant conservation success.
  • Recreational hunters would be limited to using a hook and line from land.

Louisiana may expand its wild alligator harvesting opportunities to recreational hunters if the Legislature passes a bill that secured unanimous approval in a committee hearing March 11.

Franklin state Sen. Robert Allain’s Senate Bill 244 would authorize the Louisiana Wildlife Commission to create a recreational season that would be open to 5,000 hunters annually, each with a two-gator limit.

The state already has a commercial hunting season for alligators, which is chronicled in the popular “Swamp People” TV reality series.

“We think the time is right,” Louisiana Department of Wildlife and Fisheries Secretary Tyler Bosworth testified during the Senate Natural Resources Committee hearing. “We want to provide a recreational opportunity for the common folk of Louisiana.”

Louisiana’s alligator population has exploded in the past 50 years from fewer than 100,000 to more than 3 million today. Of those, about 2 million are wild with another 1 million farmed.

That’s at least twice the population in Florida, the state with the second most number of alligators.

And their Louisiana numbers have grown throughout the state where they can be commonly spotted from Lake Martin in Breaux Bridge to Caddo and Cross lakes in Shreveport to Caldwell Parish in northeastern Louisiana.

“This is a conservation success story on the highest level,” LDWF general counsel Garrett Cole said during the hearing. “This would create a true recreational opportunity outside our commercial season.”

Garrett said hunters would compete for hunting tags through a lottery will statewide opportunities. Recreational hunters would be limited to hook and line harvesting from land. No gators could be taken by boat as commercial hunters are allowed to do.

If approved, the first season could take place beginning Oct. 1.

How a sinkhole caused a whirlpool and formed Louisiana’s deepest lake

How a sinkhole caused a whirlpool and formed Louisiana’s deepest lake


play

While Louisiana’s largest lake, the Toledo Bend Reservoir, spans 1,200 miles of shoreline, the state’s deepest lake only spans 1,125 acres.

Lake Peigneur is the deepest lake in Louisiana, with a depth measuring approximately 200 feet.

Lake Peigneur is a brackish lake, meaning it contains saltwater but has less salinity than seawater, located in New Iberia Parish in South Louisiana.

How did Lake Peigneur become the deepest lake in Louisiana?

Lake Peigneur was not always considered the deepest lake in Louisiana, as it was only a 10-foot-deep freshwater lake 40 years ago.

On Nov. 20, 1980, an oil rig crew was attempting to free a 14-inch drill bit when they heard popping noises and the rig began to tilt. Shortly after the crew abandoned the rig and headed for shore, the crew watched the 150-foot oil rig disappear into the 10-foot-deep lake.

Soon, a whirlpool formed in place of the oil rig. The whirlpool grew rapidly until it was able to suck up nearby boats, barges, trees, a house and half an island.

At the same location of the oil drilling site, there was also a salt mine, and when the whirlpool formed after the oil rig collapsed, the mine began to fill with water. As the whirlpool grew, water was able to enter the mine at such a force that it caused a geyser to spew out of the mine’s opening for hours until the lake was drained.

After the lake was emptied, the Delcambre Canal began to flow backward, marking the only time in history that the Gulf of Mexico flowed into the continental U.S. This backflow continued until the entire mine and lake were filled with water, except now the lake was filled with saltwater, according to an article published on Louisiana Tech Digital Commons.

Can you swim in Lake Peigneur?

Before the oil rig and salt mine accident, Lake Peigneur was a popular spot for fishing and recreational activities. However, since the lake is almost entirely surrounded by private property, visitors will have to enter the nearby Rip Van Winkle Gardens in order to get a closer look, according to Atlas Obscura.

While there are no reports indicating the lake is unsafe, the lake is not exactly developed for public access. However, there are things to do around Lake Peigneur, like visiting Rip Van Winkle Gardens on Jefferson Island, or visiting Avery Island to tour the Tabasco Factory.

Officials confirm Pensacola Beach residue is algae, not oil from Louisiana spill

Officials confirm Pensacola Beach residue is algae, not oil from Louisiana spill


PENSACOLA BEACH, Fla. — A local fisherman raised concerns about the substance now coating Opal Beach, citing a recent oil spill off the coast of Louisiana.

WEAR News went to officials with the Gulf Islands National Seashore and Escambia County to find out the cause.

They say it’s not related to an oil spill, but is in fact algae.

The Marine Resources Division says they can understand beachgoers’ concerns, and hope to raise awareness.

“You don’t even want to get near it because it’s so gooey and sticky,” local fisherman Larry Grossman said. “It was accumulating on my beach cart wheels yesterday, and it felt like an oil product.”

Grossman messaged WEAR News on Monday after noticing something brown and oozy in the sand. He says it started showing up by Fort Pickens and stretched down to Opal Beach.

Grossman said a park service employee told him it could be oil from a recent spill in Louisiana. So he took a message to social media, sparking some reactions and raising questions.

“it certainly didn’t seem like an algae bloom because I was in the water, I caught a fish and I put some water in the cooler to keep my fish cool and it almost looked like oil in it,” Grossman said. “I know some people think it’s an algae bloom, but it certainly smelled and felt and looked like oil.”

A Gulf Islands National Seashore spokesperson confirmed to WEAR News on Tuesday that the substance is algae.

WEAR News crews were at the beach as officials with the Escambia County Marines Resources Division came out take samples.

“What I found here washed up on the beach is some algae — filamentous algae, single celled algae — that washed ashore in some onshore winds,” said Robert Turpin, Escambia County Marines Resources Division manager. “This is the spring season, so with additional sunlight, our plants, they grow in warmer waters, with plenty of sunlight.”

Turpin says this algae is not harmful.

He also addressed the concerns that this could be oil, saying he’s familiar with what oil spills look like.

He says he appreciates when people like Grossman raise the concerns.

“The last thing in the world we want is something to gain traction on social media that is faults in nature that could harm our tourism,” Turpin said. “Our tourism is very important to our economy, and we want to give the right information out to the public so we all enjoy the beaches and enjoy them safely.”

Turpin says if you see something or suspect something may be harmful on the beach, avoid it and contact Escambia County Marine Resources.
