Oil found in Gulf crabs raises new food chain fears http://apocadocs.com/s.pl?1278190440
University scientists have spotted the first indications oil is entering the Gulf seafood chain -- in crab larvae -- and one expert warns the effect on fisheries could last "years, probably not a matter of months" and affect many species.
Scientists with the University of Southern Mississippi and Tulane University in New Orleans have found droplets of oil in the larvae of blue crabs and fiddler crabs sampled from Louisiana to Pensacola, Fla.
"I think we will see this enter the food chain in a lot of ways -- for plankton feeders, like menhaden, they are going to just actively take it in," said Harriet Perry, director of the Center for Fisheries Research and Development at the Gulf Coast Research Laboratory. "Fish are going to feed on (crab larvae). We have also just started seeing it on the fins of small, larval fish -- their fins were encased in oil. That limits their mobility, so that makes them easy prey for other species. The oil's going to get into the food chain in a lot of ways."... "I had a sort of breakdown last week," Perry said. "I've driven down the same road on East Beach in Ocean Springs for 42 years. As I was going to work, I saw the shrimp fleet going out, all going to try to work on the oil, and I realized the utter futility of that, and I just lost it for a minute and had to gather myself."
