Table 3.
anova on Coregonus albellus alevin size measured (a) 1 day after hatching, (b) 10 days after hatching, and (c) expected size at the time the yolk sac would be used up (extrapolated from loss of yolk sac volume and increase of alevin length during the first 10 days). Only estrogen- and sham-treated groups are included here. Ntotal = 114 for each statistical model. Including the two extra controls (the antimicrobial treatments) would not change any conclusions except that the main dam effects would always be significant at P < 0.001.
