- April 20 marked three years since the Gulf oil disaster erupted
- Since the 2010 spill, Louisiana's statewide oyster catch has dropped by more than 25%
- Other seafood catch numbers have rebounded and studies show the catch is safe
- But in certain areas, there's still a pronounced downturn in blue crab, shrimp, oysters
On his dock along the banks of Bayou Yscloskey, Darren Stander makes the pelicans dance.
More than a dozen of the birds have landed or hopped onto the dock, where Stander takes in crabs and oysters from the fishermen who work the bayou and Lake Borgne at its mouth. The pelicans rock back and forth, beaks rising and falling, as he waves a bait fish over their heads.
At least he's got some company. There's not much else going on at his dock these days. There used to be two or three people working with him; now he's alone. The catch that's coming in is light, particularly for crabs.
"Guys running five or six hundred traps are coming in with two to three boxes, if that," said Stander, 26.
Out on the water, the chains clatter along the railing of George Barisich's boat as he and his deckhand haul dredges full of oysters onto the deck. As they sort them, they're looking for signs of "spat": the young oysters that latch onto reefs and grow into marketable shellfish.
There's the occasional spat here; there are also a few dead oysters, which make a hollow sound when tapped with the blunt end of a hatchet.
About two-thirds of U.S. oysters come from the Gulf Coast, the source of about 40% of America's seafood catch. But in the three years since the drilling rig Deepwater Horizon blew up and sank about 80 miles south of here, fishermen say many of the oyster reefs are still barren, and some other commercial species are harder to find.
"My fellow fishermen who fish crab and who fish fish, they're feeling the same thing," Barisich said. "You get a spike in production every now and then, but overall, it's off. Everybody's down. Everywhere there was dispersed oil and heavily oiled, the production is down."
The April 20, 2010, explosion sent 11 men to a watery grave off Louisiana and uncorked an undersea gusher nearly a mile beneath the surface that took three months to cap.
Most of the estimated 200 million gallons of oil that poured into the Gulf of Mexico is believed to have evaporated or been broken down by hydrocarbon-munching microbes, according to government estimates.
The rest washed ashore across 1,100 miles of coastline, from the Louisiana barrier islands west of the Mississippi River to the white sands of the Florida Panhandle. A still-unknown portion settled on the floor of the Gulf and the inlets along its coast.
Tar balls are still turning up on the beaches, and a 2012 hurricane blew seemingly fresh oil ashore in Louisiana.
Well owner BP, which is responsible for the cleanup, says it's still monitoring 165 miles of shore. The company points to record tourism revenues across the region and strong post-spill seafood catches as evidence the Gulf is rebounding from the spill.
But in the fishing communities of southeastern Louisiana, people say that greasy tide is still eating away at their livelihoods.
"Things's changing, and we don't know what's happening yet," said oysterman Byron Encalade.
Life before the spill
Before the spill, Encalade and his neighbors in the overwhelmingly African-American community of Pointe a la Hache -- about 25 miles south of Yscloskey -- earned their living from the state-managed oyster grounds off the East Bank of the Mississippi.
Back then, a boat could head out at dawn and be back at the docks by noon with dozens of 105-pound sacks of oysters.
Now? "Nothing," says Encalade, president of the Louisiana Oystermen Association.
Louisiana conservation officials have dumped fresh limestone, ground-up shell and crushed concrete on many of the reefs in a bid to foster new growth.
It takes three to five years for a viable reef to develop, so that means Pointe a la Hache could be looking at 2018 -- eight years after the spill -- before its lifeblood starts pumping again.
"This economy is totally gone in my community," said Encalade, 59. "There is no economy. The two construction jobs that are going on -- the prison and the school -- if it weren't for those, the grocery store would be closing."
When the catch comes in, everyone wants you to know that it's safe to eat. Repeated testing has shown that the traces of hydrocarbons that do come up in the shrimp, crab and oysters are far below safety limits for human consumption.
"The monitoring of the seafood supply has been exemplary," said Steve Murawski, a fisheries biologist at the University of South Florida. "There's no incidence of people getting sick and no report of any tainted fish reaching the market."
While much of the Gulf's seafood industry has rebounded, the hardest-hit communities like Pointe a la Hache, Yscloskey and the inlets in Barataria Bay, west of the Mississippi, have not recovered.
Scientists are still trying to understand what the oil has done to the marshlands of southeastern Louisiana.
Sure, the catch is safe -- but that doesn't mean much when seafood prices are down and fuel costs are up.
"Since the spill, my shrimp production is off between 40 and 60% for the two years that I did work full time," said Barisich, who has both a shrimp boat and an oyster boat tied up at Yscloskey. "But my price is off another 50%, and my fuel is high: 60 cents a gallon higher than it's ever been."
Figures from Louisiana's Department of Wildlife and Fisheries tell a similar story.
The statewide oyster catch since 2010 is down 27% from the average haul between 2002 and 2009, according to catch statistics from the agency. In the Pontchartrain Basin, where Encalade and Barisich both work, the post-spill average fell to about a third of the pre-spill catch.
Barisich says oysters are barely worth the effort anymore.
"On the state ground -- on a perfect weather day, keep that in mind -- it's 20 sacks a day," he said. "Twenty sacks a day at $30 a sack is $600. $300 worth of fuel. $100 worth of other expenses and I pay the deckhand, I got $150 a day on a perfect day. It don't pay to go out."
And no boats going out means no fuel being sold at Frank Campo Jr.'s marina, down the bayou from Barisich's dock.
"If you don't burn it, I can't sell it to you," Campo says. "They're not doing very well with the crabs, and there's not a lot of oyster boats going out."
Demand for the oysters is off, too.
"You used to never ask the dealer if he wanted oysters," said Campo, whose grandfather started the marina. "You just showed up with them. Now, he'll call you and tell you if he needs 'em."
'Like somebody had poured motor oil all over'
Across the Mississippi from Pointe a la Hache, beyond the West Bank levees, lie some of the waterways that saw the heaviest oiling: Barataria Bay and its smaller inlets, Bay Jimmy and Bay Batiste.
Louisiana State University entomologist Linda Hooper-Bui tracks the numbers of ants, wasps, spiders and other bugs at 40 sites in the surrounding marshes, 18 of which had seen some degree of oiling.
She is part of a small army of researchers who have been trying to figure out what effect the spill will have on the environment of the Gulf Coast. Since 2010, she's recorded a sharp decline in several species of insects -- particularly spiders, ants, wasps and grasshoppers, which sit roughly in the middle of the food web.
They're top predators among insects but food for birds and fish.
Hooper-Bui said she expected their numbers to bounce back the following year: "Instead, what we saw was worse."
The reason, she suspects, is that the oil that sank into the bottom of the marsh after the spill hasn't broken down at the same rate as the crude that floated to the surface.
Instead, it's in the sediments, still giving off fumes that are killing the insects.
Some napthalenes -- crude oil components most commonly known for their use in mothballs -- appear to have increased since the spill, she said.
"They're volatile, and they're toxic," Hooper-Bui said. "And they're not just toxic to insects. They're toxic to fish. They're toxic to birds. They cause eggshell thinning in birds. We think this is evidence of an emerging problem."
Hooper-Bui said crickets exposed to the contaminated muck in laboratories die, and when temperatures were increased to those comparable to a summer day, "the crickets die faster."
By August 2011, the number of grasshoppers had fallen by 70% to 80% in areas that got oiled.
"By 2012, we were unable to find any colonies of ants in the oiled areas," she said.
Then on August 29, 2012, Hurricane Isaac hit southeastern Louisiana. The slow-moving storm sat over Barataria Bay for more than 60 hours as it crawled onto land.
When Hooper-Bui went back to the marshes after the storm, she had a surprise waiting for her.
"We discovered in Bay Batiste large amounts of what looked like somebody had poured motor oil all over the marsh there," she said. "About three-quarters of the perimeter of northern Bay Batiste was covered in this oil."
The chemical fingerprint of the oil matched the oil from the ruptured BP well, Hooper-Bui said. Other scientists confirmed that Isaac kicked up tar balls from the spill as far east as the Alabama-Florida state line, more than 100 miles from where the storm made its initial landfall.
Far from the shoreline, patches of oil fell to the bottom of the Gulf in a mix of sediment, dead plankton and hydrocarbons dubbed "marine snow." It fouled corals near the wellhead, and it's still sitting there.
"If you took a picture of a core (sample) that was collected today and took a picture of a core that was taken in September 2010, they look the same," University of Georgia oceanographer Samantha Joye said.
"What's really strange to me is, the material is not degrading," Joye added. "There's something about this stuff, the carbon in these layers, that's not degrading."
Normally, microbes go to work on free-floating hydrocarbons almost immediately, digesting the compounds. The controversial large-scale use of chemical dispersants was supposed to accelerate that process by breaking up the oil into smaller droplets that could be more easily consumed.
But that's not happening to this layer, Joye said, and the reason is unclear.
"The first thing everyone asks is, 'Do you think it's dispersants?' And I can honestly tell you, we don't know," she said.
During the spill, scientists warned that fish eggs and larvae, shrimp, coral and oysters were potentially most at risk from the use of dispersants. The Environmental Protection Agency later reported that testing found the combination of oil and dispersants to be no more toxic than the oil alone.
But that's no comfort to Encalade, who could watch planes spray dispersant on the slick from the marina where he keeps his two boats.
"We know from history, whenever you put soap in the water around camps and stuff like that, oysters don't reproduce," he said. "And we've heard BP say over and over again, 'Oh, it's like detergent.' That's the worst thing in the world you can do to an oyster."
The impact of these dispersants on marine life is still an open question, and it's something that's under review by scientists involved in the Natural Resource Damage Assessment, the federally run, BP-funded effort to figure out what the spill did to the Gulf Coast.
That assessment could take several years.
As scientists sort out the data, the Gulf fishing communities from Louisiana to Florida are still dealing with the impact of the spill. When you look at the entire expanse of the ocean, there isn't a huge amount of oil, explained Ian MacDonald, an oceanographer at Florida State University.
"You have to look hard to find any oil at all," he said.
But where the oil has been found, MacDonald said, the damage is "intense and widespread."
There is some good news: Some studies indicate that commercial fish species in different parts of the Gulf escaped the worst. Recent research at Alabama's Dauphin Island Sea Lab found that young shrimp and blue crabs off Bayou La Batre, the state's major seafood port, showed no sign of decline since the spill.
But that's no consolation for Donny Waters, a Pensacola, Florida, fisherman who has been involved with efforts to rebuild the red snapper populations off the Florida panhandle.
"I'm still catching fish. I'm not saying everything's dead," Waters said. "But it's taking me longer to catch my fish. I'm not seeing the snappers farther around reefs, whether they're natural or artificial. I'm not seeing the reefs repopulate nearly as fast since the oil spill."
'BP has retired me'
Like many in the trade, Encalade and the other guys on his dock in Pointe a la Hache can spin epic tales. But these days, they're not about the catch. More often, they're about the red tape and low-ball offers they've had to deal with in the compensation process set up after the spill -- a process they say is stacked in favor of big operators.
"I got guys been fishing out here all their life. They've got trip tickets, more than you can imagine," Encalade said, referring to the slips that document a boat's daily catch. "You know what they come back and tell a man his whole life is worth? $40,000."
The oil, the catch and the money: All converge at the big federal courthouse on Poydras Street in New Orleans, where squadrons of lawyers have massed for what promises to be a protracted brawl to figure out how much BP will end up paying for the Deepwater Horizon disaster.
BP says it has shelled out $32 billion for the disaster, including $14 billion for cleanup. It's also spent $300 million on everything from testing seafood to its ad campaign that encourages people to come back to the Gulf, and it pledged $500 million for research into the environmental effects of the disaster.
The company has paid to help replace oyster reefs in Mississippi and Louisiana and rebuild sand dunes and sea turtle habitats in Alabama and northwest Florida. In addition to monitoring part of the Gulf coastline, BP spokesman Scott Dean said, the company has planted new grass in the Louisiana marshes, where the losses sped up erosion already blamed for the loss of an area the size of Manhattan every year.
But of about 13,000 holes drilled into the beaches and marshes in search of settled oil, Dean said, only 3% have found enough to require cleanup, he said.
"The vast majority of the work has been done," Dean said. But when previously undiscovered oil from the Deepwater Horizon blowout does turn up, "We take responsibility for the cleanup," he said.
Last year, the company agreed to pay $7.8 billion to individuals and businesses who filed economic, property and health claims. But in March, the company asked a judge to halt those payments, arguing that it was facing hundreds of millions or even billions of dollars in payouts for "fictitious losses."
It's also pleaded guilty to manslaughter charges and fined $4 billion in the deaths of the 11 men killed aboard the rig and been temporarily barred from getting new federal contracts.
Now BP is back in court, battling to avoid a finding of gross negligence that would sock it with penalties up to $4,300 per barrel under the Clean Water Act -- another $17 billion-plus by the federal government's estimate of the spill. BP says that figure is at least 20% too high.
