Özet

The tanaid, Apseudopsis latreilli (Milne-Edwards, 1828) is a common crustacean species on the soft bottoms of the Mediterranean ecosystems and occurs in both clean and polluted environments. This study was aimed to determine the sensitive state of tanaid, A. latreillii to the environmental variables observed on the soft bottoms of the Dardanelles. A. latreillei abundance at the sites was analysed in comparision with the organic matter content in sediment and the environmental variables in the study area. A total of 1406 specimens of A. latreillii was recorded during the study. The highest dominance value (Di=30.37%) was for Kepez Harbour where the amount of organic matter was 25.50 +/- 12.09% in the sediment. The highest value of dominance according to the sampling seasons was 56.75% for Autumn 2008 (organic matter=21.7 +/- 7.99%). The highest sand rate (99.59%) in the sediment was found at the Eceabat sampling point. The highest positive correlation (r=0.349, P<0.05) was observed between gravel content (%) measured at the sites and total abundance (ind. 0.09 m-2).
