Gastro-somatic index (GASI), CV , food preference index (FP), and frequency of food items were determined from 447 specimens. The maximum point of GaSI index was shown in June. The CV index for this species during the study was 65.32% . According to the volume of fish digested, Encrasicholina punctifer and Sardinella sp were the basic and secondary foods , respectively. Squid and crustaceans could be considered as the incidental foods. Regarding to the species diversity of Carangidae family and importance of relation between food items, it is recommended that comprehensive feeding study of all species of this family should be carried out .
