WebApr 26, 2024 · In that study, fish fed either at mid-light (ML) or at mid-dark (MD) showed different cortisol rhythms, with the highest values displayed in the light or dark phase, respectively, after feeding time. Therefore, feeding time and schedule are important factors to consider when evaluating cortisol rhythms in fish due to the influence of food … WebIn the last part of each experiment, food was again available all the time. Colonies which showed free‐running circadian activity rhythms (with periods ranging from 22.6 to 24.8 h) during ad libitum feeding were submitted to feeding cycles with inter‐feeding intervals (T) of 22, 23, 24 and 25 h. In most of these experiments the rhythms were ...
