Silver eel samples, collected from the lagoons of Fogliano and Caprolace (Italy), were investigated for a broad range of contaminants (29 polychlorinated biphenyls, 9 polybrominated diphenyl ethers, 5 dichlorodiphenyltrichloroethane, 5 chlordanes, hexachlorobenzene, 3 hexachlorocyclohexane, and 5 metals). Concentrations of targeted compounds stand for a general low contamination pattern. Infestation by Anguillicola crassus and virus infections were also examined. No parasite infestation was found, while infected silver eels had a low prevalence for EVEX, and, for the first time in the Mediterranean area, for AngHV-1. Overall, a good quality status of escaping silver eels, for both lagoons, was highlighted by the use of integrative Indexes. A quality assessment of the ecological status of the two lagoons was carried out developing an expert judgment approach, in order to characterize the habitat of eel stocks. A Final Pressure Index was derived, whose values showed an overall limited global anthropogenic impact acting on both lagoons. Results stand for the suitability of an integrated approach to assess lagoon habitats and eel local stocks quality. This could be proposed as a tool to identify sites yielding high quality eel spawners in the Mediterranean region, in order to set up suitable management frameworks, providing elements to appraise and discuss the potential of coastal lagoons in the Mediterranean region towards the recovery of the eel global stock.

逃逸的银鳗（安圭拉鳗）的质量评估，以支持地中海沿岸泻湖的管理和保护策略。

对从Fogliano和Caprolace（意大利）的泻湖中收集的银鳗样品进行了广泛的污染物研究（29种多氯联苯，9种多溴联苯醚，5种二氯二苯基三氯乙烷，5种氯丹，六氯苯，3种六氯环己烷和5种金属）。目标化合物的浓度代表一般的低污染模式。侵染Anguillicola克拉苏还检查了病毒感染。没有发现寄生虫侵扰，而被感染的银鳗的EVEX流行率较低，而在地中海地区首次出现了AngHV-1。总体而言，通过使用综合指数突出了两个泻湖中逃逸的银鳗的良好状态。为了确定鳗鱼种群的栖息地，对这两个泻湖的生态状况进行了质量评估，并制定了专家判断方法。得出了最终压力指数，其最终值显示了对两个泻湖的总体全球人为影响有限。结果表明，采用综合方法评估泻湖栖息地和鳗鱼当地种群质量是合适的。可以提议将其作为一种工具，以识别在地中海地区产生高质量鳗鱼产卵场的地点，
