BIOLOGíA REPRODUCTIVA DEL COCOBOLO (ANDINOACARA PULCHER MUSILOVá ET AL. 2009) (PISCES: CICHLIDAE) EN LA CIéNAGA GRANDE DE LORICA (CóRDOBA), COLOMBIA

the reproductive biology of cocobolo (andinoacara pulcher musilová et al. 2009) in the ciénaga grande de lorica, sinú river basin (córdoba) 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.
