Bluefin and Yellowfin Tuna Show Effects of 2010 Gulf Oil Spill

Bluefin_trevally_trioThe National Oceanic and Atmospheric Administration backs researcher reports that crude oil from the 2010 Gulf of Mexico Spill by BP may be responsible for heart defects and premature death in tuna. According to a study published in the Proceedings of the National Academy of Sciences, crude oil exposure may slow heart rhythm, or cause uncoordinated heart rhythm, in bluefin tuna, yellowfin tuna and an amberjack species. Heart damage can be responsible for reduced swimming performance, jeopardizing a fish’s survival.

Zintro expert John Menchaca is a petrochemicals consultant who specializes in chemicals, oil/gas services and equipment, global sourcing and procurement. He discusses the effect of the study on BP’s reputation. “The biggest effect however might be as a reminder to global oil companies and their service providers of the never ending public relations associated with poor safety and operating practices. The result is that the oil and gas industry will operate at very safe levels despite the current future drilling in ultra-deep water, occurring in deeper and more difficult conditions.”

On April 20, 2010, crude oil began gushing into the Gulf. During the next 87 days, it discharged nearly 5 million barrels. The question of how the spill would affect fish and marine species has been a matter of discussion among federal agencies and scientists during the four years since the event.
