Intensive culture of Artemia urmiana in semi-flow through system feeding on Algae Dunaliella and Wheat bran 2 2 Artemia is a tiny crustacean that lives in salty lakes. Artemia urmiana is one of the important species of it. 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 Artemia with semi-flow through system using unicellular algae ( Dunaliella ) and wheat bran as food source. The tanks inoculated with 5000 newly hatched Artemia larvae/liter. Artemia were harvested for 14 days. The average production of live Artemia in each three tanks reached to 7116.7 g. The mean length of Artemia 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. 1 - 3 9 - - Behrooz Atashbar Iran - - Naser Agh Iran - - Ehsan Kmerani Iran Artemia urmiana Dunaliella Urmia Lake survival growth

The Brine Shrimp Artemia and hypersaline environments microalgal composition: a mutual interaction 2 2 Hypersaline environments are essential, integral and dynamic part of the biosphere. 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 Artemia) to provide a better understanding the dynamics of these unique ecosystems. Algal composition as the main food source of Artemia determines Artemia growth, reproduction rates, brood size, density, lipid index and cysts yields. Furthermore, the reproduction mode of Artemia 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 Artemia population in temperate large hypersaline lakes such as the Great Salt Lake (USA), Urmia Lake (Iran) and Mono Lake (USA). However, Artemia grazing pressure has significant effects on microalgal density. 1 - 19 27 - - Fereidun Mohebbi Iran Artemia hypersaline microalgal composition Dunaliella
