Reproduction for S. barracuda occurs sexually through external fertilization. Sexual maturity is reached between the second and third year for males, and the third to fourth year for females. Barracudas do not exhibit sexual dimorphism, and sex can only be determined upon examination of the gonads. Adults spawn between April and October in southern Florida (de Sylva 1963), releasing eggs and sperm into the water column. Literature detailing spawning behavior in the great barracuda is lacking. However, in similar species, females may spawn several times in one season, releasing over 500,000 eggs each time (de Sylva 1963).
