The effects of the temperature and of the photoperiod on the bull frog sexual maturation of frogs weighing 94.22 g ± 12.03, maintained for thirty days under temperatures of 20, 23, 26, 29, 32 and 35°C, with photoperiod of 12/12 hours of light/hours of darkness (h L/D), were evaluated. Temperature affected the weights of the fat body and liver, that varied according to quadratic models, and higher weights of fat body at 27.27°C and of liver at 26.81°C were considered. […]
