Sažetak
The ichthyofauna composition of the wetland ecosystem in the Bardača area (Bosnia and Herzegovina) was described with the aim of indication on the richness and necessary protection of the biodiversity of this sensitive swamp region. During 2004, qualitative and quantitative fish samplings were carried out, according to seasons, in Matura and Brzaja rivers, the main tributaries of the drainage area around the Sava River. Fish samplings were carried out using an electro–generator pulse and removal method. Analysis of the sampled fishes consisted of species determination and estimation of yield for average density and biomass (N/m2 or m3 and g/m2 or m3). It could be said that during one year examinations, the presence of 24 fish species from 7 families has been determinate. In addition, the analysis of fish diversity was carried out by means of species richness, Shannon–Weaver index, evenness and Simpson index. According to analyzed data, it could be observed that 2 allochtonous pest species, Carassius auratus gibelio and Ictalurus nebulosus presents the most dominant fish species in these waters in almost all sampling seasons.
