NEW ORLEANS (IPS/Al Jazeera) – "The fishermen have never seen anything like this," Jim Cowan told Al Jazeera. "And in my 20 years working on red snapper, looking at somewhere between 20,000 and 30,000 fish, I've never seen anything like this either."
Cowan, with Louisiana State University's Department of Oceanography and Coastal Sciences, started hearing from fishermen about fish with sores and lesions in November 2010.
Cowan's findings reflect those of others living along vast areas of the Gulf Coast that have been impacted by BP's oil and dispersants.
Gulf of Mexico fishermen, scientists and seafood processors have told Al Jazeera they are finding disturbing numbers of mutated shrimp, crab and fish that they believe are deformed by chemicals released during BP's 2010 oil disaster.
Along with collapsing fisheries, signs of malignant impact on the regional ecosystem are ominous: horribly mutated shrimp, fish with oozing sores, underdeveloped blue crabs lacking claws, eyeless crabs and shrimp - and interviewees' fingers point towards BP's oil pollution disaster as being the cause.
Tracy Kuhns and her husband Mike Roberts, commercial fishers from Barataria, Louisiana, are finding eyeless shrimp.
"At the height of the last white shrimp season, in September, one of our friends caught 400 pounds of these," Kuhns told Al Jazeera while showing a sample of the eyeless shrimp.
According to Kuhns, at least 50 per cent of the shrimp caught in that period in Barataria Bay, a popular shrimping area that was heavily impacted by BP's oil and dispersants, were eyeless. Kuhns added: "Disturbingly, not only do the shrimp lack eyes, they even lack eye sockets."
"Some shrimpers are catching these out in the open Gulf (of Mexico)," she added, "They are also catching them in Alabama and Mississippi. We are also finding eyeless crabs, crabs with their shells soft instead of hard, full grown crabs that are one-fifth their normal size, clawless crabs, and crabs with shells that don't have their usual spikes … they look like they've been burned off by chemicals."
On Apr. 20, 2010, the BP-operated Deepwater Horizon oilrig exploded, triggering the release of at least 4.9 million barrels of oil. BP then used at least 1.9 million gallons of toxic Corexit dispersants to sink the oil.
Keath Ladner, a third-generation seafood processor in Hancock County, Mississippi, is also disturbed by what he is seeing.
"I've seen the brown shrimp catch drop by two-thirds, and so far the white shrimp have been wiped out," Ladner told Al Jazeera. "The shrimp are immune-compromised. We are finding shrimp with tumours on their heads, and are seeing this everyday."
While on a shrimp boat in Mobile Bay with Sidney Schwartz, the fourth-generation fisherman said that he had seen shrimp with defects on their gills, and "their shells missing around their gills and head."
"We've fished here all our lives and have never seen anything like this," he added.
Ladner has also seen crates of blue crabs, all of which were lacking at least one of their claws.
Darla Rooks from Port Sulphur, Louisiana told Al Jazeera she is finding crabs "with holes in their shells, shells with all the points burned off so all the spikes on their shells and claws are gone, misshapen shells, and crabs that are dying from within … they are still alive, but you open them up and they smell like they've been dead for a week".
Rooks is also finding eyeless shrimp, shrimp with abnormal growths, female shrimp with their babies still attached to them, and shrimp with oiled gills.
"We also seeing eyeless fish, and fish lacking even eye-sockets, and fish with lesions, fish without covers over their gills, and others with large pink masses hanging off their eyes and gills."
Rooks, who grew up fishing with her parents, said she had never seen such things in these waters, and her seafood catch last year was "ten per cent what it normally is."
"I've never seen this," she said, a statement Al Jazeera heard from every scientist, fisherperson, and seafood processor consulted about the seafood deformities.
"The dispersants used in BP's draconian experiment contain solvents, such as petroleum distillates and 2-butoxyethanol. Solvents dissolve oil, grease and rubber," Riki Ott, a toxicologist, marine biologist and Exxon Valdez survivor, told Al Jazeera. "It should be no surprise that solvents are also notoriously toxic to people, something the medical community has long known."
The dispersants are known to be mutagenic, a disturbing fact that could be evidenced in the seafood deformities. Shrimp, for example, have a life cycle short enough that two to three generations have existed since BP's disaster began, giving the chemicals time to enter the genome.
Pathways of exposure to the dispersants are inhalation, ingestion, skin, and eye contact. Health impacts can include headaches, vomiting, diarrhea, abdominal pains, chest pains, respiratory system damage, skin sensitisation, hypertension, central nervous system depression, neurotoxic effects, cardiac arrhythmia and cardiovascular damage. They are also teratogenic - able to disturb the growth and development of an embryo or foetus - and carcinogenic.
Cowan believes chemicals named polycyclic aromatic hydrocarbons (PAHs), released from BP's submerged oil, are likely to blame for what he is finding, due to the fact that the fish with lesions are from "a wide spatial distribution that is spatially coordinated with oil from the Deepwater Horizon, both surface oil and subsurface oil. A lot of the oil that impacted Louisiana was also in subsurface plumes, and we think there is a lot of it remaining on the seafloor." […]
