September Fishing Expedition

By

A team of scientists, professional anglers, and videographers recently embarked on a fishing trip to capture wild mahi-mahi broodstock (i.e. breeding adults) for the University of Miami’s Experimental Hatchery program. The ongoing research is part of the RECOVER Consortium, which is focusing on the effects of crude oil on mahi-mahi and red drum in the wake of the 2010 Deepwater Horizon Oil Spill. RECOVER (Relationships of Effects of Cardiac Outcomes in fish for Validation of Ecological Risk) is a Gulf of Mexico Research Initiative consortia based at the University of Miami’s Rosenstiel School of Marine and Atmospheric Science.

MIAMI – Researchers at the UM Rosenstiel School of Marine and Atmospheric Science were awarded over $29 million in research grants from the Gulf of Mexico Research Initiative (GoMRI) to lead the Consortium for Advanced Research on the Transport of Hydrocarbons in the Environment (CARTHE) and to study the toxic effects of crude oil on fish that reside in the Gulf of Mexico. UM Rosenstiel School was the only research institution to receive two of the 12 highly competitive research grants awarded by GoMRI.

“We are thrilled that GoMRI awarded such a substantial portion of the overall research funds to the two exceptional research teams put together by our scientists in collaboration with many partners at various institutions,” said UM Rosenstiel School Dean Roni Avissar. “This will allow these two teams to conduct the critical research studies necessary to understand the impacts of oil spills from both oceanographic and biological perspectives.”

We know that oil spills have plenty of negative effects on organisms living nearby, but little is known about the precise impacts that exposure to oil can have on the health of fish hearts. For the Gulf of Mexico, that is an important question to answer because it could hold clues to the long-term chances of fish survival there.

To find out what sort of impacts oil exposure has had on fish in the Gulf, scientists at the University of California, Riverside, University of Miami, University of North Texas and the University of Texas at Austin are focusing on redfish and mahi mahi. The two economically important sport fish need to be studied to protect their ecotourism value, researchers say.
