The aim of this study was to assess the effect of deltamethrin on rainbow trout (Oncorhynchus mykiss). Control and experimental group of fish were exposed to Decis EW 50 pesticide preparation (active substance 50g/l of deltamethrin). The acute semistatical toxicity test lasting 96h was performed on rainbow trout juveniles. The 96hLC(50) value of Decis EW 50 was 0.02mg/l. Examination of haematological and biochemical profile and histological tissue examination was performed on 1-2-year-old rainbow trout after 96h of exposure to Decis EW 50 in a concentration of 0.02mg/l. The experimental group showed significantly lower values (p<0.05) of plasma glucose, alanine aminotransferase, cholinesterase and significantly higher (p<0.05) values of erythrocyte count, haemoglobin content, haematocrit and plasma total protein, albumins, ammonia, aspartate aminotransferase, creatinekinase and calcium compared to the control group. The deltamethrin-based Decis EW 50 pesticide preparation was classified among substances strongly toxic for fish.
本研究旨在评估溴氰菊酯对彩虹鳟（Oncorhynchus mykiss）的影响。对照组和实验组的鱼分别暴露于敌敌畏 EW 50 农药制剂（有效成分 50g/l 的溴氰菊酯）中。对幼彩虹鳟进行了为期 96 小时的急性半静态毒性试验。敌敌畏 EW 50 的 96 小时 LC(50)值为 0.02mg/l。在 0.02mg/l 的敌敌畏 EW 50 浓度下暴露 96 小时后，对 1-2 龄彩虹鳟进行了血液学和生物化学特征及组织学检查。实验组的血浆葡萄糖、丙氨酸氨基转移酶、胆碱酯酶显著降低（p<0.05），红细胞计数、血红蛋白含量、血细胞比容和血浆总蛋白、白蛋白、氨、天冬氨酸氨基转移酶、肌酸激酶和钙显著升高（p<0.05）。与对照组相比，基于溴氰菊酯的敌敌畏 EW 50 农药制剂被归类为对鱼类具有强毒性的物质。
