In 2012-2014 in the near-shore area of the Absheron Peninsula on the border of the Middle and South Caspian 156 cyprinid fishes of 4 species were investigated, and 32 species of the parasites were found, 14 of them were specific for cyprinids. Except of 7 species of monogeneans, all the parasites of cyprinids evolve with the change of hosts. Most of them infect the fish when it eating benthic invertebrates, intermediate hosts of nematodes can be zooplankton organisms too. Roach was infected with 19, kutum with 16, shemaya with 12, and carp with 14 species of parasites. Between the parasite fauna of 4 fish species was not too high similarity (26.1-54.6%), because every fish species had its own specific parasites. Differences in the parasite fauna of the various fish species are mainly connected with peculiarities of their life-style and food compositions.
