With oil spills, and other sources of aromatic hydrocarbons, being a continuous threat to coral reef systems, and most reef fish species being protected or difficult to collect, the use of the invasive lionfish (Pterois volitans) might be a good model species to monitor biomarkers in potentially exposed fish in the Caribbean and western Atlantic. The rapid expansion of lionfish in the Caribbean and western Atlantic, and the unregulated fishing for this species, would make the lionfish a suitable candidate as biomonitoring species for oil pollution effects. However, to date little has been published about the responses of lionfish to environmental pollutants. For this study lionfish were collected in the Florida Keys a few weeks after Hurricane Irma, which sank numerous boats resulting in leaks of oil and fuel, and during the winter and early spring after that. Several biomarkers indicative of exposure to PAHs (bile fluorescence, cytochrome P450-1A induction, glutathione S-transferase activity) were measured. To establish if these biomarkers are inducible in PAH exposed lionfish, dosing experiments with different concentrations of High Energy Water Accommodated Fraction of crude oil were performed. The results revealed no significant effects in the biomarkers in the field collected fish, while the exposure experiments demonstrated that lionfish did show strong effects in the measured biomarkers, even at the lowest concentration tested (0.3% HEWAF, or 25 μg/l ƩPAH50). Based on its widespread distribution, relative ease of collection, and significant biomarker responses in the controlled dosing experiment, it is concluded that lionfish has good potential to be used as a standardized biomonitoring species for oil pollution in its neotropical realm.

由于溢油和芳香烃的其他来源不断威胁珊瑚礁系统，并且大多数礁鱼受到保护或难以收集，因此需要使用侵入性l鱼（Pterois volitans）可能是监测加勒比海和西大西洋可能裸露的鱼类中生物标志物的良好模式物种。Caribbean鱼在加勒比海和西大西洋的迅速扩张以及对该物种的无管制捕捞，将使其成为油污影响生物监测物种的合适人选。但是，迄今为止，关于of鱼对环境污染物的反应的报道很少。在这项研究中，l鱼在飓风“艾尔玛”（Irma）袭击几周后被收集在佛罗里达礁岛，该沉船沉没了许多船，导致机油和燃料泄漏，并在此后的冬季和初春期间。测量了指示暴露于PAHs的几种生物标志物（胆汁荧光，细胞色素P450-1A诱导，谷胱甘肽S-转移酶活性）。为了确定这些生物标志物是否在暴露于PAH的l鱼中可诱导，进行了使用不同浓度的高能量水调节原油馏分的剂量试验。结果表明，野外采集的鱼类对生物标志物没有明显影响，而暴露实验表明，即使在最低测试浓度（0.3％HEWAF或25μg/ l ƩPAH50）下，l鱼对所测量的生物标志物也确实显示出强大的作用。基于它的广泛分布，相对易于收集以及在受控剂量实验中明显的生物标志物响应，得出的结论是，l鱼有很好的潜力可以用作新热带地区油污染的标准化生物监测物种。进行了不同浓度的高能水调节馏分原油的加液实验。结果表明，野外采集的鱼类对生物标志物没有明显影响，而暴露实验表明，即使在最低测试浓度（0.3％HEWAF或25μg/ l ƩPAH50）下，l鱼对所测量的生物标志物也确实显示出强大的作用。基于其定量分布，相对易收集性以及在受控剂量实验中明显的生物标志物响应，得出的结论是，fish鱼在其新热带地区具有良好的潜力，可作为标准化的生物监测物种用于油污染。进行了不同浓度的高能水调节馏分原油的加液实验。结果表明，野外采集的鱼类对生物标志物没有明显影响，而暴露实验表明，即使在最低测试浓度（0.3％HEWAF或25μg/ l ƩPAH50）下，l鱼对所测量的生物标志物也确实显示出强大的作用。基于其定量分布，相对易收集性以及在受控剂量实验中明显的生物标志物响应，得出的结论是，fish鱼在其新热带地区具有良好的潜力，可作为标准化的生物监测物种用于油污染。暴露实验表明，即使在最低测试浓度（0.3％HEWAF或25μg/ l ƩPAH50）下，l鱼的生物标志物也确实显示出强大的作用。基于其定量分布，相对易收集性以及在受控剂量实验中明显的生物标志物响应，得出的结论是，fish鱼在其新热带地区具有良好的潜力，可作为标准化的生物监测物种用于油污染。暴露实验表明，即使在最低测试浓度（0.3％HEWAF或25μg/ l ƩPAH50）下，l鱼的生物标志物也确实显示出强大的作用。基于其定量分布，相对易收集性以及在受控剂量实验中明显的生物标志物响应，得出的结论是，fish鱼在其新热带地区具有良好的潜力，可作为标准化的生物监测物种用于油污染。
