Due to markedly higher vitellogenin concentrations in fish from the positive control
group, this group was excluded from subsequent statistical analyses. Analysis of the
remaining 4 groups showed significant differences (Kruskall–Wallis test: Q = 12.57, N
=48; p = 0.006). In a multiple comparison of the mean ranks, significantly (p < 0.05)
increasing levels of vitellogenin concentration in whole-body homogenates of fish exposed
to 5.0 mg·l-1 of Butisan 400 SC compared to fish from both the control group and the group
exposed to 1.0 mg·l-1 of Butisan 400 SC were observed
