Abstract: 
As the potential of Litopenaeus vannamei to tolerate wide ranges of environmental conditions, it is desirable candidate for shrimp farming. This research conducted in Dec- Jan 2004 in Bushehr province, and various temperatures and salinities has been studied. PL25 of L.vannamei reared in temperatures of 15, 18, 20, 25 and 30oc, and salinities of 30, 35, 40, 45 and 50 ppt during 45 days with three replicates for each treatment. The data analyzed by SPSS and Minitab soft wares, and growth rate indices showed significant differences at 30 ْc in relation to other treatments. The maximum weight and length gained at 30 and 40 ppt salinities, these results showed significant differences with other treatments. Different salinities did not showed significant effects on specific growth rate. Mortality rate in all temperature and salinity treatments was negligible, except at temperatures 15 and 18oc. As the final results, L.vannamei showed wide range tolerance of salinities up to 50 ppt, and best growth resulted at temperature 30oc and salinity of 40 ppt. Hence it can be selected as a suitable candidate for farming in Persian Gulf area.
