The present study was conducted to achieve the life cycle characteristics of six Artemia populations (one bisexual and five parthenogenetic) from Iran. The cysts of parthenogenetic strains were collected from Maharlu, Incheh, Varmal and Qom salt lakes and Lagoons at the periphery of Lake Urmia. Cysts of the bisexual Artemia urmiana were collected from the Lake Urmia. All cysts strains were hatched using the standard procedures and the nauplii from all populations were reared at 80 g L(-1) at laboratory conditions. Survival and total length of the Artemia were measured on days 8, 11, 14, 17, 20 and 23 of culture. Randomly selected adult animals were studied for eight reproductive and four life span characteristics. The findings showed that parthenogenetic Artemia from Maharlu, Incheh lakes and from Lagoons at the vicinity of the Lake Urmia had significantly highest (p < 0.05) values of survival rate (73 and 62.8%, respectively) compared to bisexual A. urmiana and parthenogenetic strains from Qom and Varmal lakes (49.6, 29.2 and 23.2%). No significant differences were observed in all growth strain populations when cultured under similar laboratory conditions. Artemia populations from Maharlu, Qom lakes and from Lagoons in many occasions had significantly highest (p < 0.05) reproductive values compared to other three populations including the bisexual A. urmiana. The results showed the highest heterogeneity and intrapopulation variations among parthenogenetic population strains.
