This is the first record of the common bream, Abramis brama (Linnaeus, 1758), introduced into the Tikveš Reservoir, Crna Reka river, as a part of the Vardar river basin in the Republic of Macedonia. Twenty-two specimens of this cyprinid fish species were captured in the Tikvesh Reservoir on October 2014. Two of them were immediately frozen for further analysis in the laboratory at the Institute of Animal Science – Fishery Department. The distin¬guishing morphometric and meristic features – fin ray formulae (D III/10, A III/26, P I/15, V II/8), lateral lines with 53 scales, a deep body, and a small head and eyes – are in accordance with those reported for the species Abramis brama. The two fish were aged 5+. Their further spread to Republic of Macedonia is to be expected.
