The health status of eels (Anguilla anguilla) developing in three estuaries of the NW Portuguese coast with different types and levels of pollution was compared in relation to morphometric parameters, Fulton condition index (F index) and several biomarkers. Relatively to the reference population, glass eels from the Lima estuary had lower weight and length, cholinesterase (ChE) and lactate dehydrogenase (LDH) inhibition, and lower levels of some anti-oxidant parameters, while yellow eels also showed a decreased F index, and increased Na(+)/K(+)-ATPase and lipid peroxidation (LPO) levels. Relatively to the reference population, glass eels from the Douro estuary had increased Na(+)/K(+)-ATPase and glutathione-S-transferase activities and LDH inhibition, while yellow eels also had ChE inhibition and increased LPO. Overall, these results indicate that eels from polluted estuaries showed a poor health status than those from a reference estuary, and that adverse effects become more pronounced after spending several years in polluted estuaries.
在与形态参数、福尔顿状况指数（F 指数）和几种生物标志物有关的情况下，比较了在西北葡萄牙海岸三个具有不同类型和污染水平的河口发育的鳗鱼（安圭拉鳗）的健康状况。与参考种群相比，来自利马河口的玻璃鳗体重和体长较低，胆碱酯酶（ChE）和乳酸脱氢酶（LDH）抑制作用以及一些抗氧化参数水平较低，而黄鳗的 F 指数也较低，同时 Na(+)/K(+)-ATPase 和脂质过氧化（LPO）水平增加。与参考种群相比，来自杜罗河口的玻璃鳗的 Na(+)/K(+)-ATPase 和谷胱甘肽-S-转移酶活性以及 LDH 抑制作用增加，而黄鳗的 ChE 抑制作用和 LPO 增加。总体而言，这些结果表明，与来自参考河口的鳗鱼相比，来自污染河口的鳗鱼的健康状况较差，而且在污染河口生活几年后，不利影响变得更加明显。
