Age, growth and mortality of longspine seabream, Argyrops spinifer in the Arabian Gulf waters off Qatar were investigated. me-study was conducted on 664 fish obtained from Qatar National Fishing Company. The results revealed that the maximum age of studied fish was 18 years. The length/scale relationship was TL = -7.1478 + 0.232TS (r=0.925). The relationship between total length and total weight was best fit by a curvilinear equation: TW = 0.0398TL,.,',T,h.e von Bertalanffy growth equation obtained from backcalculated dataawas : L = 81.01 [1-e-0.094 ('OB)]. The rates of growth in length and weight (% increment) were highest at the end of the first year of life, followed by a gradual decrease throughout the fish life. The instantaneous total mortality estimate (Z), natural mortality (M) and fishing mortality (F) were 0.43, 0.29 and 0.14, respectively, while survival rate was 0.65.
