A total of 1120 fish was collected from different landing sites along the Iranian waters. Yearly analysis of the reproductive stages and gonadosomatic index showed a single reproductive cycle beginning in March and continued with a single spawning period from August to September. The mean length at first maturity (Lm 50%) for females was 83.6 Cm. The sex ratio was M: F = 0.97:1 which was not significantly (P > 0.05) different among samples (χ2 test). Isometric growth for this species was approved.   %> http://jifro.ir/article-1-4-en.pdf %P 233-244 %& 233 %! %9 Orginal research papers %L A-10-1-4 %+ %G eng %@ 1562-2916 %[ 2010
