The effect of Roundup on gametes of grass carp Ctenopharyngodon idella Val. – preliminary research

Abstract

b>The study was conducted on the eggs (roe) and sperm of grass carp (Ctenopharyngodon idella Val.) obtained during artificially induced spawning. The effect of Roundup on eggs was assessed using the following concentrations of the herbicide: 0.0 (control), 0.1, 0.2, 0.5, 2.0, 5.0 and 10.0 mg/l. Sperm motility was measured at concentrations of 0.0 (control), 0.1, 0.5, 2.0, 5.0, 10.0, 20.0 and 50.0 mg/l. The study showed that the herbicide increased swelling of grass carp eggs and significantly reduced the duration of sperm motility.
