The fishery of the spotted sardinella, Amblygaster sirm (Walbaus, 1792) has been the most important catch in the Egyptian waters. The age and growth of the A. sirm were updated for the Red Sea, Egyptian waters, in addition to an evaluation of the captures over the last 12 years (2006–2018). To specify the age, more than one reader was determined in the present study. As a result, the recorded life history ranged from 0 to 3 years old. The growth parameters were investigated with various models (von Bertallanfy, Gompertz, Richard and logistic). The growth-length relationship (L_∞) and the growth rate (K) were estimated with 274 mm and 0.35 year^-1 respectively. The importance of the present study lies in being a biological data provider with respect to sardine species in the Red Sea, and hence the decision to take the action for the management of such species could be elaborated.
