První nález Romanogobio vladykovi v povodí Nidy, Polsko
 Nowak, M. ; Mendel, Jan ; Szczerbik, P. ; Koščo, J. ; Klaczak, A. ; Popek, W.
The Danube whitefin gudgeon Romanogobio vladykovi Fang, 1943 belongs to the R. albipinnatus (Lukasch, 1933) species group. In the territory of Poland so-called whitefin gudgeon was recorded for the first time in the middle stretches of Vistula River (1965). Since then the species has been found in some 20 localities in the Vistula and Odra River drainages. In May and July 2009 two specimens identified initially as belonging to the R. albipinnatus species group were caught in the main course of Nida River. Molecular approach based on combination of both mitochondrial and nuclear markers confirmed occurrence of R. vladykovi on Polish territory. This conclusion alters the knowledge about the distribution of the species of the R. albipinnatus species group. Kottelat and Freyhof (2007) considered that the territory of Poland is inhabited by R. belingi, whereas R. vladykovi is restricted only to the drainage area of Danube River.

Revitalization of the Morava River vs. business plans
 Halačka, Karel ; Mendel, Jan ; Papoušek, Ivo ; Vetešník, Lukáš
The course of the Morava River is an important supranational biocorridor with significant biological potential. This is attested also by results of recent ichthyological surveys. There is a plan of revitalization projects aimed at making migration barriers passable and also at repatriation of indigenous animal species. At the same time, there is a number of business plans focusing on the area, while their realization would severely restrain or even disallow the revitalization efforts. Therefore, a complex biological survey of the whole Morava River course should be performed first, and a detail project of naturalization of the floodplain, including the still existing fragments of original river channel, should be elaborated subsequently. Such project would then constitute a qualified basis for centrally assessed potential business plans.
