Abstract:   (4947 Views)
The many specious of Caspian Seafish immigrate to Anzaliwetland for reproduction and some larvae spend the primary levels of their growth in this wetland. Therefore, Zooplankton has an important role in nutrition in Anzali wetland. For this reason, the geneses identification and abundance (finding the relation between abundance with some environmental factors) of Copepoda (a major group of zooplankton) hasbeen studied in Anzali wetland, Estuaryregion and Caspian Sea. The sampling done in 5 stations in Caspian Sea, Estuary region and three stations in Anzali wetland which contain Nahangroga,Sorkhankol and water entrance to west wetland(Abkenar entrance)(for comparing the density in three different regions with different salinity) since March 2011 to September 2011. The samples filtered through the 30-micron plankton net and then transferred to laboratory for analysis. Sevengenuses of Copepoda identified in this study. The most important genuses were Acartia sp.,Cyclops sp. and Thermocyclops spite relation between the density of Copepodawith environmental factors such as Oxygen, Temperature and pH were direct and with electrical conductivity (EC) and Transparency were inversed. The major density of Copepoda have been seen in the entrance of west wetland (Abkenar entrance) (107.47 per liter) and among the three regions of Sea, Estuary and Wetland, the Wetland has more density (with 59.26 per liter). Furthermore, the major density of Copepoda among months has been seen in August with 68.8 per liter. Also the studies have showed that the density of Copepoda in both Caspian Sea and the entrance of west wetland (Abkenar entrance) have had the meaningful statistics difference.
