Growth rate, survival and food conversion ratio were compared for two species of shrimp Penaeus semisulcatus and Fenneropenaeus indicus in Bushehr Province in summer 2002. The research was done with two treatments each in three replications in 0.4 ha ponds. Twenty five post larvae of the shrimps in stage PL sub(12) with a mean weight of 5mg were stocked per square meter of the ponds and cultured for 109 days. We found significant differences during the first 31 days in SGR between P. semisulcatus and F. indicus (P0.05). The mean final harvest rate was 903.33kg and 1025.00kg in each pond for P. semisulcatus and F. indicus, respectively. No significant differences in physical and chemical parameters were observed between the two species......
