The paper summarizes the data on tench parasites from the natural water bodies of the Republic of Moldova, obtained by the authors within 1985-2022 period. In the composition of the surveyed wild tench symbiocomplex, a total of 106 eukaryotic species and undetermined forms are revealed, which belong to Metamonada (1), Euglenozoa (6), Ciliophora (28), Sporozoea (3), Amoebozoa (2), Cnidaria (16), Plathelminthes (27), Nemathelminthes (8), Acanthocephales (1), Annelida (1), Mollusca (4), Arthropoda (4), Microsporidia (1), Oomycota (3), and Chytridiomycota (1). The composition of parasites of the tench is formed on the whole by common and widely-distributed species, only several (14) of the recorded species are host-specific to this fish. A total extensity of infestation of tench was 100%. Based on their distribution and sometimes their numerical abundance, the representatives of the ciliophorans, plathelminthes, cnidosporans and nemathelminthes prevailed in the examined fish. A number of potentially dangerous parasites for ichthyocenosis (about 40 species) and with epidemiologically significance for warm-blooded animals (11 species) were found in the examined fishes. The infestation of the tench with parasites wasn’t accompanied by fish morbidity or mortality. It is concluded that the epizootic situation in the populations of wild tench is relatively favourable, compared with some other cyprinids, and its maintenance or cultivation in ponds as an additional fish will not negatively affect the condition of cultivated fish. The species names, their localization and host-specificity, the values of infestation supplied with epizootic or epidemiologic significance of the revealed parasites are provided. Also, the ichthyopathological potential of this fish in the pond conditions of the region is discussed
