Hafezieh, M.
Artemia uramiana hatched in the laboratory condition were reared in small glass aquariums for 20 days in 4 replications and fed with Chaetocerus sp. and marine Chlorella sp. as treatments. Culture conditions such as temperature, salinity and pH were kept the same for all treatments and replicates. A one-way analysis of variance, showed a significant difference in the mean growth rate of the Artemia treated with different food items (P<0.05), but no significant differences was found in the Artemia survival rate (P=0.4321). The average survival rate and the mean length of Artemia fed on Chaetocerus sp. were 95%, 97%, 93%, 94% and 7.77, 7.76, 8.01, 7.87; for the four replications. For the Artemia fed on Chlorella sp. the values were 82%, 80%, 77%, 85% and 7.06, 7.66, 7.53, 6.83 respectively.
