The reproductive biology of the Bocachico, Prochilodusmagdalenae,in the San Jorge River, Colombia, was studied. The species is a fish with sexual proportion female: male of 1.2:1, different than expected. It presents synchronous ovocitary development in two groups, an annual spawning that extends from April to September associated to the hydrological cycle of the San Jorge River, length at first maturity estimated in 30.2 cm TL, large oocytes of 950 µm, and average fecundity of 109 972 oocytes, whose equation was F = 7271,6 OW0,60, r = 0,93, n = 14.
