The distribution and population dynamics of Ostracoda and their response to environmental factors have been analyzed in Crimean hypersaline lakes based on data from a long-term monitoring study (2005–2016). Only one representative of this class, Eucypris mareotica (Fischer, 1855), occurs in these lakes. The species was recorded in the Crimean lakes at a maximum salinity of 300 g/L. The frequency of occurrence of this species correlated negatively with salinity. This species reached high abundances in plankton (650 000 ind./m3), benthos (565 000 ind./m2), and floating mats of filamentous green algae Cladophora spp. (9 900 000 ind./kg of wet weight of the mat). Ostracods were shown to reduce the concentration of calcium and magnesium in the water as a result of using these elements for the construction of their shells. The possibility of using the shells of ostracods for paleoclimatic and palaeolimnological reconstructions was discussed.
