摘要我们采用了2009-2012年进行的2次渔业独立鲨鱼调查的渔获量数据以及稳定同位素分析，以调查2010年深水地平线石油泄漏对佛罗里达大弯地区大型沿海鱼类的潜在影响。5种指示鱼种（3种鲨鱼和2种硬骨鱼）的单位捕捞努力量仅在2种情况下逐年变化显著。5种指示种中有2种的稳定同位素谱在年际间差异显著，但相对差异较小，且各类群间的模式不一致。我们的研究结果没有提供证据表明，深水地平线石油泄漏有显着影响的相对丰度和大型沿海鱼类在佛罗里达的大弯的食物网结构。
Abstract 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.
