Ever since the Artemia as per live feed shows an important role in the most ornamental fish feeding, so aninvestigation on optimal growth and survival conditions of this favorable species would be very important for its breeding and propagation. In this research the in vitro effects of water temperature and And two concentrations of algal cells Dunaliellas alinain order to study the survival and longevity of adult Artemia urmiana from mating to the death has been investigated At two different temperatures and 60 ppm of salinity in  through four treatments. The One-way ANOVA analysis illustrated that there was no significant statistical difference amongs treatments in case of longevity during reproduction. Also, in high concentrations of algae- both temperature range- it seems that the longevity have fallen. Although the statistical analysis revealed no significant relationship between longevity or the survival of Artemia at different temperatures, the results obtained from the effect of temperature factor showed that the longevity during reproductive period was higher in 20° C in comparison with 27° C.
