AB  - Monthly data of  length  composition  for  silver pomfret, Pampus argenteus, were  recorded  from  the Northern Persian   Gulf (Khuzestan province), between April 2004 to March 2005. ELEFAN in the software package FiSAT was used to analyse   the  length  frequency  data.  The maximum measured  fork  length  and weight  were  312 mm  and  1191  g  respectively.  The   parameter values of the von Bertalanffy growth function were: L∞= 339 mm; k = 0.55 year  -1   and t0= -0.16 year. The estimated   value of the instantaneous rate of total mortality, Z based on length converted catch curve was 2.07 year  -1  . The instantaneous   rate of natural mortality, M based on the growth parameters and mean environmental temperature was 0.58 year  -1  . The annual   instantaneous fishing mortality rate, F was estimated to be 1.49 year  -1  . The exploitation rate, E was 0.72 year  -1   and the results   from the yield-per-recruit analysis indicated that the resource was heavily over-exploited, and some measures of management   should be rapidly implemented to protect the silver pomfret population in the Northern Persian Gulf.
