Abstract
Compared to older data sources, 13 new fish species for the Miniș River were found: Phoxinus phoxinus, Hucho hucho, Barbus balcanicus, Rutilus rutilus, Carasius gibelio, Leucaspius delineatus, Ameiurus nebulosus, Pseudorasbora parva, Cottus gobio, Rhodeus amarus, Alburnus alburnus, Chondrostoma nasus, Cobitis elongata. Eight species known here from the past were still found: Salmo trutta, Squalius cephalus, Alburnoides bipunctatus, Gobio obtusirostris, Barbatula barbatula, Eudontomyzon danfordi, Sabanejewia balcanica, Romanogobio banaticus. The unnatural structure of the fish communities and the identified changes of the fish zonation along Miniș River reveal a complex set of impacts from human activities on this lotic ecosystem.
