| 摘 要： | 本文研究次致死浓度Cu~(2+)对罗非鱼呼吸生理的影响。通过比较15天里各污染组鱼呼吸频率、振幅和鳃盖运动的变化,得出罗非鱼异常鳃盖运动频率随Cu~(2+)浓度的增加而递增,咳嗽运动先于驱逐反射(expulsion reflex),提示鱼类的咳嗽运动和驱逐反射可作为次致死浓度下Cu~(2+)污染的敏感生物学监测指标。

| Abstract: | The effect of subthlethal concentrations of copper ions on respira-tory physiology of freshwater fish (Tilapia sp.) was studied. By comparing therespiratory frequency, respiratory amplitude and opercular movement among thegroups of fish reared in various concentration of Cu~(2+) for 15 days, it was foundthat the frequency of abnormal opercular movement increased with increasingconcentrations of copper ions, and the cough movement appeared ealier than theexpulision reflex did. This suggested that cough movement and expulsion reflexcould be used as the sensitive biological monitoring indexes under pollution ofsublethal concentration of copper ions. |
