Using computer assisted sperm analysis (CASA) to monitoring the effects of zinc and Cadmium pollution on fish sperm

Since the quality of sperm is affected by water industrial or agriculture pollution, sperm motility was measured as a sensitive and accurate bioindicator of water quality. In this study, sperm motility was measured by a computer assisted sperm analysis after ۲۴ hours exposure of sperm to different concentration of heavy metals) Cadmium and Zinc). The results show that the sperm motility was not related to the duration of exposure but to the metals concentration ration. The concentration of ۱۰۰۰ppm zinc or ۲۰۰۰ppm Cadmium could have adverse effect on sperm motility.
