Australian catfish, T. tandanus were exposed to a short term pulse of chlorpyrifos at 2 or 10 μg L(-1) and grown in optimal conditions to investigate the effect of the pesticide on fish growth. The final weight was lower in fish exposed to chlorpyrifos (8.54 ± 0.19 and 8.77 ± 0.44 g) respectively compared to the control fish (10.5 ± 0.72 g) while the hepatosomatic index in fish exposed to chlorpyrifos was a higher (1.86 ± 0.10 and 2.01 ± 0.12) than in the control fish (1.65 ± 0.14). Both bi-weekly growth rate and brain Acetylcholinesterase (AChE) activity increased with post-exposure time.
澳大利亚鲶鱼 T. tandanus 在 2 或 10μg/L(-1) 的氯蜱硫磷短期脉冲暴露下生长在最佳条件下，以研究杀虫剂对鱼类生长的影响。与对照组（10.5 ± 0.72 g）相比，暴露于氯蜱硫磷的鱼的最终体重分别较低（8.54 ± 0.19 和 8.77 ± 0.44 g），而暴露于氯蜱硫磷的鱼的肝体比指数（1.86 ± 0.10 和 2.01 ± 0.12）高于对照组（1.65 ± 0.14）。每周两次的生长率和大脑乙酰胆碱酯酶（AChE）活性都随着暴露后的时间而增加。
