In 1997-2007. the structure of populations of Acanthocyclops trajani Mirabdullayev et Defaye (Copepoda, Cyclopoida) in water bodies of Kazakhstan was studied. It was shown that cyclops prefers water bodies with TDS up to 3.0 g/dm 3 . The abundance of cyclops increased in the gradient of phosphate concentrations statistically significantly. In the same direction the dominance of males in the populations of cyclops increased. The appearance of individuals with morphological anomalies was associated with toxic pollution of water bodies. The results demonstrate that the structure of cyclops populations can be an indicator of the ecological state of aquatic ecosystems.
