In this study, the periodic changes in density and population structure, the generation number, reproduction characteristic and reproduction period of Artemia salina (L., 1758) living in Tuz Lake in 1995 have been investigated. Some physical parameters of lake water at the certain stations have been determined. It has been observed that A. salina is distributed near the coastline of 10 kilometers between the stations Devekonaǧi and Çalören in the east side of Tuz Lake.
