%X the reproductive biology of cocobolo (andinoacara pulcher musilov¨¢ et al. 2009) in the ci¨¦naga grande de lorica, sin¨² river basin (c¨®rdoba) colombia, was evaluated. individuals collected between january and december 2005 were analized, with total length (tl) ranging between 7.2-14.5 cm and total weight (wt) between 9.1-89.1 g. the gonads were placed in gilson solution, the vazzoler scale was applied and sexual proportions, a sexual maturity index, spawning season, the length at first maturity, ovocite diameter, and fecundity were estimated. 169 females, 125 males, and 4 undifferentiated individuals were studied, with sexual proportions of 1.4:1 female: male documented, differing from expected. the length at first maturity was estimated at 9.5 cm tl for both sexes; ovocite diameter ranged between 1.352 and 1.605 m and fecundity was estimated in 954 ovocites, with a best-fit equation f = 0.185 lt3,67, n = 14, r = 0.70. the cocobolo is a fish with partial spawning, with a prolonged spawning season that extends throughout the year, with small oocytes and medium fecundity.
