Abstract

The first data on the parasite fauna of the common bream (<i>Abramis brama</i>), acclimatized to the Irkutsk Reservoir, are presented. The study reveals that the parasitic community of these fish comprises six eurytopic species: myxosporidians (2), cestodes (1), trematodes (2), and nematodes (1). It is suggested that the bream and other fish species in the reservoirs of the Angara River host a significantly greater diversity of parasites than currently recorded. Given the near-total lack of data on fish parasites in the Irkutsk Reservoir, the urgency of comprehensive parasitological and molecular genetic studies is emphasized.
