Abstract
This study was performed to compare the efficiency of six microalgae namelyDunaliella tertiolecta,Tetraselmis suecica,Nannochloropsis oculata,Chaetocerossp., Chlorellasp. and Spirolinasp.on the growth, survival rate and reproduction efficacy inArtemia urmiana in laboratory conditions.Artemia cysts were harvested from Urmia Lake and hatched according to the standard method. Live microalgae were cultured using the f/2 culture medium.Artemia survival was determined in treatments on days 8, 11, 14, 17 and 20. A highly significant difference (p<0.01) were found among three microalgae in terms of length growth, survival rates and reproduction characteristics inA. urmiana. In spite of higher length growth ofA.urmiana fed onN. oculata thanA. urmiana fed byT. suecica but survival and reproduction in the latter was better than the first treatment. In general,D. tertiolecta was more efficient than other microalgae examined in the present study onA. urmiana concerning not only to growth and survival but also to reproduction mode. So, it is preferred to feedA. urmiana.
