The present communication deals with the effect of fenitrothion (0.04 ppm) on the carbohydrate metabolism of the european eel Anguilla anguilla and its recovery from intoxication. Analysis of various parameters such as glycogen, lactate and glucose was made on different eel tissues after 2, 8, 12, 24, 32, 48, 56, 72 and 96 hr of fenitrothion exposure. Subsequently, the fish were allowed recovery periods of 8, 12, 24, 48, 72, 96, 144 and 192 hr in clean water, and the same parameters were evaluated. Muscle glycogen content decreased significantly during the exposure time, while blood glucose levels increased markedly. Gill, muscle and blood lactate values increased during pesticide exposure. Most of the metabolic disorders did not persist after allowing recovery in clean water during less than a week. The observed effects of fenitrothion on fish metabolism are discussed in relation to a stress syndrome and probable reasons for alterations have been exposed.
本通讯研究了杀螟硫磷（0.04 ppm）对欧洲鳗鲡（Anguilla anguilla）碳水化合物代谢的影响及其从中毒状态恢复的情况。在杀螟硫磷暴露2、8、12、24、32、48、56、72和96小时后，对不同鳗鱼组织中的糖原、乳酸和葡萄糖等各种参数进行了分析。随后，让鱼在清水中恢复8、12、24、48、72、96、144和192小时，并对相同参数进行评估。在暴露期间，肌肉糖原含量显著下降，而血糖水平显著升高。在农药暴露期间，鳃、肌肉和血液中的乳酸值升高。在清水中恢复不到一周后，大多数代谢紊乱情况并未持续。结合应激综合征讨论了观察到的杀螟硫磷对鱼类代谢的影响，并阐述了变化的可能原因。
