For the 1493 animals involved in this experiment (657 males and 836 females) biometrical data were obtained (weight, length and tympanum diameter) and developmental stages of gonads were determined. Female sizes at first maturation were 10,33 cm and 109,78 g and for males it was around 8,09 cm; all males above 45 g were already in the maturation process. The relationship between tympanum diameter and body length (RTC) was considered a good index for male maturation.416-420porBullfrog reproduction in captivitySize at first maturationEstimativa do tamanho da primeira maturação sexual da rã - touro, Rana catesbeiana, no sistema Anfigranja de criação intensivaEstimate of bullfrog size at first sexual maturation, Rana catesbeiana, in the intensive growing Anfigranja systemArtigo2-s2.0-3142594455
