Plasma levels of thyroid hormones (T₄ and T₃) and pineal AANAT activity exhibited prominent diurnal rhythms during all the four phases (quiescent, progressive, breeding, and regressive) of the fish, Clarias gariepinus. During all the four phases, we observed that (i) the acrophase (peak) of the circadian rhythm of both T₃ and T₄ occurred around midday, while the acrophase of AANAT activity rhythm ...
