| Description | Food habits of three Neogobius species (N. kessleri, N. fluviatilis and N. melanostomus) were studied in Austrian, Slovak, Croatian and Bulgarian stretches of the River Danube. The results were compared with the composition of macrozoobenthos with the aim to evaluate the level of food selectivity in individual Neogobius species and food competition between them. Crustaceans (Corophium, Dikerogammarus and Jarea) predominated in food offer in upper sampling sites whilst lower sampling sites were colonized mainly by molluscs. Besides them, numerous occurrences of the mysid Limnomysis benedeni were recorded in Slovak and Croatian section of Danube respectively. The diet of gobiids consisted mainly by dominating benthic animals - amphipods and molluscs. |
