For data analysis different methods Were undertaken such as Bertalanfy equation for growth parameter Beverton and Holt for total mortality rates, pauly's imperical model for natural mortality rate and cohort Analysis for biomass estimation. Totall catch with taking into account of pauching , estinmated 15500 tonnes reported by scientific committee of catch and fishing harbor relief of Iranian Fishery Company .The total recorded catch of beach seine cooperatives was 10667 tons that comprise 69% of the total catch .
