We employed catch data from 2 fishery-independent shark surveys conducted from 2009-2012, as well as stable isotope analysis, to investigate potential effects of the 2010 Deepwater Horizon oil spill on large coastal fishes in Florida's Big Bend region. The catch-per-unit-effort of 5 indicator species (3 sharks and 2 teleosts) varied significantly among years in only 2 cases. The stable isotope profiles were significantly different among years in 2 of 5 indicator species, but the relative differences were small, and patterns were not consistent among taxa analyzed. Our results provide no evidence that the Deepwater Horizon oil spill had a significant effect on the relative abundances and food-web structure among large coastal fishes in Florida's Big Bend.
