In this study some cysts of Artemia were collected from Incheh lake in Golestan province and then were incubated to obtain nauplii.
These hatched nauplii were fed by Chlorella sp., and synechococcus sp., in three different treatments and three replicates with densities of 20, 40 and 60 specimen/lit and were reared up to adult stage. The period of rearing for above mentioned densities of two different algae were 15, 17 and 20 days; and in 16, 19 and, 23 days respectively.
The average fecundity and mean length of Artemia fed on Chlorella sp. were 83.E 69.8 and 34.5 cysts/individual and 104, 10.1, and 9.1mm length; and for the Artemia fed on Synechococcus sp. were 54.1, 36.8 and 19.3, cysts per individual and 10.0, 9.0 and 8.8mm length, respectively. There were significant difference in growth rate and fecundity among the traetments of each group of Artemia (P<0.05).
