Computer assisted sperm analysis (CASA) has been used to analyse the effects of cadmium and zinc on the motility of fish sperm treated either for 24h after partial dilution in an extender, or during the final dilution step on the microscope stage during video recording. The progressive motility of catfish sperm, which was not affected by storage for 24h, was decreased after exposure to 100 ppm cadmium or 2000 ppm zinc in extender for 24h. Only 1000 ppm cadmium or 2000 ppm zinc had any effect on motility when added to sperm at the final dilution stage. These results suggest that concentrations of cadmium which have been found to be present in fish gonads as a result of bioaccumulation from the water or diet may decrease the motility of sperm during... |
