Vitellogenin concentrations in blood plasma samples of rainbow trout exposed at the WWTP Eriskirch in aquaria connected to the conventional effluent or to the additionally treated effluent in 2013 and 2014; means and standard deviation (SD) are shown. Analyzed by Biosense rainbow trout vitellogenin ELISA kit. N-numbers 2013 females: negative control n = 9, WWTP effluent n = 6, additional treatment n = 8; males: negative control n = 1, WWTP effluent n = 7, additional treatment n = 3. No significant differences with Steel–Dwass test; p > 0.05. N-numbers 2014 females: negative control n = 6, WWTP effluent n = 5, additional treatment n = 4; males: negative control n = 13, WWTP effluent n = 6, additional treatment n = 10. No significant differences with Steel–Dwass test; p > 0.05. No significant differences between years; p > 0.05
