Abstract
Caspian Sea in Iran, particularly in the study of habitat as one of the most important water resources in the country and the largest brackish lake is of remarkable importance . The purpose of this research is to better understand the research community Khzrmy Myvbntyk Sea Ostracoda as environmental indicators suitable for assessing the environmental context are used. Geographical location between the coastal city of Nor to NOSHAHR is studied . This study sampled in two seasons (winter 1390 and spring 1391) along four transects , each with 4 stations ( at depths of 20 and 5,10,15 mm ) was performed using grab Van Vienna . Physical and chemical factors in the water near the seabed , including temperature , dissolved oxygen , pH and electrical conductivity were measured during sampling , sediment and other geological studies were conducted in a laboratory setting . Based on studies of the sediments in the area consist of fine sand , very fine sand , silt and clay were determined. Among the environmental factors, significant positive correlation between the abundance of Ostracoda with the amount of electrical conductivity of organic materials and Jude Law (P<0/05). In this study , Ostracoda 9 species belonging to 7 genera of 7 families were identified
