Popis The fish community in the shoreline zone of the Bulgarian section of the Danube River (r. km 376-840) was studied in different seasons of 2005-2006. Totally 38 sites were sampled using two methods-beach seining and electrofishing. In total, 44 fish species belonging to 12 families were recorded. Of them, 39 species are indigenous to the ichthyofauna of the Danube basin. First records of Gasterosteus aculeatus and nonindigenous Gambusia holbrooki are reported from the main channel of the Bulgarian Danube. In October 2005, Neogobius fluviatilis (91.18%) occurred most frequently followed by Alburnus alburnus and N. kessleri (88.24% each). Regarding the beach seine samples, N. fluviatilis, followed by A. alburnus and N. melanostomus, reached the highest abundance. Regarding the electrofishing, A. alburnus was most abundant followed by N. kessleri and Leuciscus idus. Nineteen of the species recorded are of high conservation concern in Bulgaria.
