“…According to Bagheri et al (2010) and GWRO (2010), there was a strongly negative correlated between salinity and freshwater discharge in the southwestern Caspian Sea during [2001][2002]. In additions, our findings were similar to the previous findings reported by ;Dumont (1998); Kideys and Moghim (2003); Bagheri and Kideys (2003); Zaker et al (2007); Nasrollahzadeh et al (2008aNasrollahzadeh et al ( , 2008b in the Caspian.…”

“…In addition, Nasrollahzadeh et al (2008a) reported, the process of eutrophication is accompanied by a shift in the existing qualitative and quantitative relationship between the major phytoplankton groups. According to Mirzajani et al (2010) found similar occurrence in the Black Sea, Chesapeake Bay, Mediterranean Sea, and Caspian Sea.…”

“…Recently, Kideys et al (2005; reported there was a significant increase in phytoplankton abundance and noxious visibility in the Caspian Sea. Moreover, Nasrollahzadeh et al (2008a) and Bagheri et al (2010) observed an increase in phytoplankton abundance in 2001-2002 and 2005 as compared to previous years. According to Khodaparast (2006) and Makaremi et al (2007) (Khodaparast, 2006;CEP, 2006;Jamshidi et al, 2009).…”

“…Therefore, varied hydrological regimes and nutrient levels input by the Anzali wetland and the Sefidrood river can impact the phytoplankton structure in the coasts of southwestern Caspian Sea. A few phytoplankton studies have been conducted on the south Caspian Sea in recent years (Nasrollahzadeh et al, 2008a(Nasrollahzadeh et al, , 2008b(Nasrollahzadeh et al, , 2008cRoohi et al, 2010;Ganjian et al, 2010 …”

Problem statement:The Caspian Sea ecosystem has been suffered with many problems since 1980s. Aanthropogenic pollution from heavy metals, hydrocarbons, pesticides, changes in the quantity of nutrient inputs by rivers, are significant threats to biodiversity and biological resources such as plankton structure in the Caspian Sea. According to the significant of phytoplankton community in marine system. The state of the fluctuations of phytoplankton communities of the southwestern Caspian Sea was investigated and compared with the findings of before 2006. Approach: Phytoplankton abundance and species composition of the Caspian Sea were evaluated by using samples collected at 12 stations along three transects. The study revealed that diatoms were higher than other groups of phytoplankton in 2006. The hydrology variation, increased fresh water inflow via rivers and a rise in nutrients concentrations have played important roles in blooming of phytoplankton species, e.g., the diatoms in this study, which is also known from other marines. Similar studies on determination of the effects of environmental degradation on phytoplankton and hydrological processes should be taken into account in near future.
