Fig. 7. Effects of treatment on embryonic growth. (A) Mass and (B) length of embryos at day 0 (11 October) and day 35 (15 November) after water exposure of pregnant mother fish to isopropanol (control, C), 25 µgl^-1 4-tert-octylphenol (4-tOP) (OP25), 100 µgl^-1 4-tOP (OP100) or 0.5 µgl^-1 17ß-oestradiol (E₂). Values are means ± S.E.M. Significant difference from the respective control is indicated by asterisks (^*P<0.05, ^**P<0.01, ^***P<0.001). Significant difference of 35-day control from the 0-day control is indicated by a dagger (P<0.05).
