Abstract

The present study investigated the effects of Cd, Cu and Zn on the sperm motility of Caspiomyzon wagneri. The sperm of the specimens were exposed to 0.01, 0.1, 1, 10, 100 and 1000 mg L-1 of the heavy metals, and the duration of sperm motility and percentage of motile sperms were measured using a compound microscope and digital camera. Based on the results, sperm motility parameters decreased with increasing the concentrations of heavy metals. A concentration of 1000 mg L-1 of heavy metals stopped completely the motile sperms. The present study indicated that heavy metals have detrimental effects on sperm motility and possibly decrease the fertilization and hatching rates of C. wagneri in the spawning ground, and thus a serious threat to the survival of this rare and native species.

镉、铜、锌对华氏七鳃鳗精子活力指标的影响

本文研究了Cd、Cu和Zn对瓦氏卡匹米松精子活力的影响。分别在0.01、0.1、1、10、100和1000 mg L-1的重金属环境下，用复合显微镜和数码相机测量精子活动时间和活动精子百分比。结果表明，精子活力参数随着重金属浓度的增加而降低。浓度为1000 mg L-1的重金属完全使精子失去运动能力。本研究表明，重金属对华氏金鸡的精子活力有不利影响，可能降低华氏金鸡在产卵场的受精和孵化率，从而严重威胁这一稀有本土物种的生存。
