FINDING OF THE EUROPEAN BROOK LAMPREY, LAMPETRA-PLANERI IN THE MORAVARIVER

The first documented finding of the European brook lamprey, Lampetra p laneri (Bloch, 1784), is described from the main channel of the Morava River (tributary of the Danube, basin of the Black Sea). The sole spe cimen was caught on 2 July, 1992, near Bludov. Some other findings of this species from the basin of the Black Sea are also discussed. The n ecessity of a more careful approach was emphasized for the evaluation and revision of historical faunistical data from the upper part of the Danube watershed, mainly those pertaining to lampreys and denoted ori ginally as L. planeri or its synonyms. Besides the Ukrainian brook lam prey, Eudontomyzon mariae (Berg, 193 1), undoubtedly, also Lampetra pl aneri could occur there.
