Age, growth and mortality of the red snapper, Lutjanus purpureus Poey, 1867, were estimated based on lecture of 152 urohials of 1561 individuals caught in the region of Guianas, located between 06° - 10° LN and 54° - 61° LW, in 1988, by means of a research survey of the B/l "Dr. Fridtjof Nansen". Seven age groups could be distinguished within the annual zones of the urohial. The theoretical growth curves was adjusted according to the values of the von Bertalanffy growth model parameters: L∞ = 91.99 cm; K = 0.245 per year; to = - 0.499 yr. The values of natural mortality M = 0.255, were obtained using the equation of Taylor; and total mortality Z = 0.703 per year, by aplication of the linearized catch curve method.
