Study finds significant liver damage in Gulf of Mexico red snapper

March 17, 2021 — A study completed by researchers from the University of South Florida has revealed almost every red snapper studied in the Gulf of Mexico in the wake of the Deepwater Horizon spill showed signs of liver damage.

Red snapper is the latest Gulf species studied by researchers at the USF College of Marine Science in the wake of the devastating 2010 oil spill. Erin Pulster, a USF researcher and lead author of the study, said the results give “early warning signs of a compromised ecosystem.” Pulster and her team recently had their findings published in Aquatic Toxicology.

Red Snapper in the Gulf show signs of stress

March 11, 2021 — Nearly 100 percent of the red snapper sampled in the Gulf of Mexico over a six-year period by University of South Florida (USF) marine scientists showed evidence of liver damage, according to a study reported in Aquatic Toxicology.

The study is the first to correlate the concentration of crude oil found in the workhorses of the digestive system—the liver, gall bladder, and bile—with microscopic indicators of disease, such as inflammation, degenerative lesions, and the presence of parasites. The team sampled nearly 570 fish from 72 Gulf locations between 2011 to 2017 in the wake of the historic 2010 Deepwater Horizon oil spill.

“The results add to the list of other species we’ve analyzed indicating early warning signs of a compromised ecosystem,” said Erin Pulster, Ph.D., first author of the study and researcher at the USF College of Marine Science.

Pulster and the team of researchers studying  in Gulf of Mexico fishes have previously reported high levels of oil exposure in yellowfin tuna, golden tilefish, and red drum as well.
