Temperature treatment during ovarian recrudescence influenced temporal changes in plasma testosterone (T) and oestradiol‐17β (E 2 ). In fish exposed to 8 and 12° C early in the cycle the peaks of both T and E 2 were delayed by 4 weeks in comparison with those of fish held at 4° C throughout the experiment. These differences were accompanied by corresponding shifts in the timing of ovulation.
