The last decades witnessed the widespread degradation of the freshwater
ecosystems, mainly by anthropogenic activities and improper management.
Sustainable water management is possible only if we have knowledge about the
ecosystem ecological status, community structure and species diversity. We have
investigated ichthyofaunal diversity of rivers of the Drinjača catchment area. Rivers
Zeleni Jadar and Studeni Jadar are main tributaries of the river Jadar, which is the
left tributary of the river Drinjača. Electrofishing was performed in December 2016.
The highest species diversity was observed in river Drinjača where eight fish species
were determinated. In river Jadar we identified six fish species, while in Studeni Jadar
only one species was present. All identified fish species were autochthonous, while
no allochthonous or invasive fish species were detected. According to saprobic
system, Drinjača and Jadar were categorized as β-mesosaprobic (water quality class
II) and Studeni Jadar was assessed as oligosaprobic (water quality class I).
