Life history parameters and biology of fish like aging, growth, mortality and exploitation levels are essential to evaluate the fishery status of fish stocks. The common bluestripe snapper Lutjanus kasmira in the Shalatein fishing area, Red Sea, Egypt was assessed in this study for the first time. Age was determined based on otolith readings and the maximum life span was five years for males and females. The confidence interval for slope b of the length-weight relationship indicates positive allometric growth (b= 3.128; CI: 3.071-3.185). The von Bertalanffy equation for the growth in length was Lt = 33.76 [1 - e^{-0.35(t + 1.15)}]. The total mortality coefficient Z, natural mortality coefficient M, and fishing mortality coefficient F were estimated at 1.58, 0.59, and 0.99 year^-1, respectively. The current exploitation rate E was 0.62 year^-1. The critical lengths of the species were 13, 17.97 and 19.70 cm TL for length at recruitment, length at first capture and length at first sexual maturity respectively. The results indicated that the stock of L. kasmira in the Shalatein fishing area is currently overexploited where the current F and E were greatly higher than the optimum ones which produces the maximum sustainable yield. It is recommended that the current fishing pressure should be reduced, in addition to protecting the spawning stock biomass during the spawning season and reducing the natural mortality rates. Also, urgent improvement for the fish
