Oil spill: What is the threat to Gulf of Mexico seafood?
The Gulf of Mexico seafood industry is insisting that the oil spill has caused no major damage yet. But if nursery grounds are harmed, the impact could be serious.
Along with officials' consistently cautious predictions about the scope of the Gulf of Mexico oil spill, another group has been calling for a tempering of dire oil-spill forecasts: the Gulf of Mexico seafood industry.Skip to next paragraph

Already battered by imports of shrimp and other seafood – 80 percent of the seafood Americans eat is imported – the Gulf of Mexico seafood industry is eager to avoid a panic about the safety of their catch. And for good reason.
So far, the seafood is safe. Gulf oysters are never exposed to surface waters, so unless the oil sinks, the oysters could well survive, as could shrimp and stocks of redfish and other species who can swim away from the spill.
But in the longer term, the spill could pose a significant danger to the industry if it damages fragile nursery grounds or drips down into oyster beds.
"If you talk about the sky falling too early, then people stop buying Louisiana oysters, blue crabs, and shrimp, and since we're talking about people's livelihoods you have to be very, very careful about saying things that will get dispersed around the world," says Ed Overton, an emeritus professor of environmental science at Louisiana State University. "On the other hand, they won't get a paycheck if there's no oysters."
The massive and expanding oil slick is now nosing up to the Gulf Coast shoreline. But at first, officials said the well wasn't leaking after the Deepwater Horizon oil rig exploded, burned and then sank. Then they underestimated by a factor of five the amount of oil that was spewing from the well – now saying that it is not 1,000 barrels a day, as previously thought, but 5,000.
Even as globs of oil and mousse-like residue are now set to impact the coast, official language remains cautious. "You are getting ahead of yourself a little when you try to speculate and say this is catastrophic. It is premature to say this is catastrophic," said Coast Guard Admiral Mary Landry on Wednesday. "I will say this is very serious."
That language suits the Louisiana seafood industry just fine.
"No one should be worrying about whether the shrimp they're having for dinner is going to have oil on it," Mike Voisin, the past president of the National Fisheries Institute, told CNN earlier this week. "[T]hose areas that have oil in them will be blocked by state health officials and not harvested."
