mineralization, the Large Sea is still alive – some biological communities demonstrated high resistibility to the salinity growth. According to (Sapozhnikov et al., 2008), over 40 species of microalgae currently populate the Large Sea. The dominant specie in zooplankton is Artemia parthenogenetica, whose total stock in the Large Sea is as high as 50,000 t (Arashkevich et al., 2009). The ongoing Aral Sea crisis also involves a variety of serious problems ranging from air pollution and deterioration of water resources to human health issues and significant challenges to the regional economy.
