Calanoid copepod Centropages ponticus, endemic to the Mediterranean and Black Sea, is the only pelagic copepod species which was found in the closed ecosystem of the saline Lake Mir on Dugi Otok, eastern Adriatic Sea. This paper presents some important morphological characteristics and the annual population structure investigated from November 1999 to October 2000 at one station in the deepest part of Lake Mir. Investigation topics included the temporal distribution and abundances of nauplii, copepodites and adult specimens, as well as the density of their faecal pellets. It would appear that only C. ponticus is adapted to the extreme conditions of the lake, low winter and high summer temperatures, as well as long period of hypersaline conditions. During the summer-autumn period, the abundances of nauplii, copepodites and adult specimens reach extreme values. Lake Mir is ecologically very interesting and generally among very rare habitats. Our results suggest the necessity for further complex research of this natural laboratory for the purpose of its full protection.
