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 agriculturepollution, sperm motility was measured as a sensitive and accurate bioindicator ofwater quality. in this study, sperm motility was measured by a computer assistedsperm analysis after 24 hours exposure of sperm to different concentration ofheavy metals) cadmium and zinc). the results show that the sperm motility wasnot related to the duration of exposure but to the metals concentration ration. theconcentration of 1000ppm zinc or 2000ppm cadmium could have adverse effecton sperm motility.
