Abstract :In this study, it was aimed to determine the status of Artemia population in Tuz Lake The study was conducted between October 2014 and September 2015. Artemia and water samples were taken seasonally in autumn and winter, monthly in spring and summer from 3 stations. Artemia population was found in 3th station in May, June and July. Total abundance was calculated as 3.2±0.2 – 42±5 number x10³/m³. Also, the density of Artemia planktonic cysts were 960±110 – 271200±97000 number x10³/m³. The highest density of cysts was observed in July when the population was about to disappear and matures were dominant. The largest cysts diameter values were measured in May on hydrated cysts. The water parameters were determined in terms of temperature insert ignore into journalissuearticles values(6.40±0.10 °C-29.4±1.00 °C);, dissolved oxygen insert ignore into journalissuearticles values(1.26±0.08 mg/L);, salinity insert ignore into journalissuearticles values(226±5.77 g/L-366±20.13 g/L);, pH insert ignore into journalissuearticles values(7.37±0.00 - 8.12±0.01);, water depth insert ignore into journalissuearticles values(8±1.00 cm-35±1.5 cm);, and transparency insert ignore into journalissuearticles values(7.66±0.60 cm-35±1.50 cm);. In previous studies insert ignore into journalissuearticles values(conducted in Tuz Lake between 1994 and 2017);, it was claimed that climatic change and human effects has been an important factor in fluctuations of Artemia population. In conclusion, data evaluated from the present study results showed that the water criteria insert ignore into journalissuearticles values(physically, chemically and biologically); should be monitored and taken measures against pollution for the sustainable lake management.
