The health status of Sciaenops ocellatus was studied by qualitative and quantitative histopathological analysis through histological damage prevalence and degree of tissue change (DTC) in response to 96 h and 9 days of exposure to 0.1, 0.8, and 8 g/L of light crude oil in seawater. The histology of the liver, spleen, kidney, and gills of the fish were analyzed and compared between treatments. Our results showed that the exposed fish developed lesions associated with degenerative and necrotic changes. The highest frequency of damage and DTC scores were observed in the liver and kidney from 96 h to 9-days post-exposure. Generalized additive models of location, scale, and shape, showed that the DTC was strongly associated with crude oil compounds such as napthalene, Cd, Ni, Pb, and bile polycyclic aromatic hydrocarbon metabolites. Our findings suggest that exposure to crude oil affects fish health, producing irreversible histological damage.

Sciaenops ocellatus的健康状况通过对海水中 0.1、0.8 和 8 g/L 轻质原油暴露 96 小时和 9 天的反应，通过组织学损伤发生率和组织变化程度 (DTC) 通过定性和定量组织病理学分析进行研究。分析和比较处理之间的鱼的肝脏、脾脏、肾脏和鳃的组织学。我们的研究结果表明，暴露的鱼会出现与退化和坏死变化相关的病变。从暴露后 96 小时到 9 天，在肝脏和肾脏中观察到最高频率的损伤和 DTC 评分。位置、规模和形状的广义加法模型表明，DTC 与原油化合物如萘、镉、镍、铅和胆汁多环芳烃代谢物密切相关。
