The effect of fipronil on some reproduction parameters of zebrafish (Danio rerio)

Our research investigated the effects of fipronil on the reproduction dynamics and parametersof the zebrafish (Danio rerio). The experiment consisted in exposing ready to spawn fish and the spawnitself to three different concentrations of the test substance. The survival rate over the 21 days ofexposure was 100% in both the three experimental groups and control group. However, the effects onreproductive parameters were evident even at the lowest concentration of fipronil applied while exposureto the highest dose of fipronil decreased the spawn obtained considerably and as well the fecundationand hatching percentages, compared to the control group.
