Parasite fauna of common bream Abramis brama (Linnaeus, 1758) (Cypriniformes: Leuciscinae) from the Irkutsk Reservoir

The first data on the parasite fauna of the common bream (Abramis brama), 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.
