Its high nutritional values and various forms with many applications have caused this creature to be considered as the most valuable live food for the cultured aquatic animals .Current research was carried out in order to find out the bio-technique for intensive culture of <em>Artemia</em> with semi-flow through system using unicellular algae ( <em>Dunaliella</em> ) and wheat bran as food source. The tanks inoculated with 5000 newly hatched <em>Artemia</em> larvae/liter. <em>Artemia</em> were harvested for 14 days. The average production of live <em>Artemia</em> in each three tanks reached to 7116.7 g. The mean length of <em>Artemia</em> in the last day of culture period was 4.09 mm and mean survival rate 42 percent. It was concluded that partial removal of waste material from culture medium helps in higher production rate of live biomass.http://www.journal-aquaticscience.com/article_73587_ccc9c513466b37c9bb1bbaae169fa6c1.pdfArtemia urmianaDunaliellaUrmia LakesurvivalgrowthengInt.

Their management and protection depend on an understanding of the influence of salinity on biological productivity and community structure. The aim of this study was to review the relationships between the two basic biological components of hypersaline environments (micro-algae and <em>Artemia</em>) to provide a better understanding the dynamics of these unique ecosystems. Algal composition as the main food source of <em>Artemia</em> determines <em>Artemia</em> growth, reproduction rates, brood size, density, lipid index and cysts yields. Furthermore, the reproduction mode of <em>Artemia </em>depends on food levels, so that at the low food levels the main reproduction going into cysts. On the other hand, seasonal fluctu-ations of algal abundance influence <em>Artemia</em> population in temperate large hypersaline lakes such as the Great Salt Lake (USA), Urmia Lake (Iran) and Mono Lake (USA). However, <em>Artemia </em>grazing pressure has significant effects on microalgal density.http://www.journal-aquaticscience.com/article_73589_769d55e750f0bc2b49e63fa33c08e114.pdfArtemiahypersalinemicroalgal compositionDunaliellaengInt.
