Monthly changes in the gonadosomatic index indicate that the main spawning season of Parupeneus barberinus in Aqaba extends from May to August for females and from May to June for males. Males in the 4 years age‐group (63–4%) and the 5 years age‐group (65–1%) are predominant. The von Bertalanffy growth equation parameters calculated from mean total length data are: L α = 32–8cm; K=0–225; (t o =−0–73 for males and L α = 32–7cm; K=0–206; t o = −0.82 for females. The length‐weight regression coefficients for males (2.85) and females (2.8) are not significantly different and they indicate a negative allometric growth. There is no significant change in condition factor with age.
