Abstract

The aims of the present study are: 1) to present water quality data of the Sava Lake observed over a medium-term period; 2) to describe its fish community composition. Analyzed data were obtained from regular monitoring reports. Water quality parameters (dissolved oxygen, suspended solids, BOD, COD, total phosphorous and total nitrogen) were within the limits issued for I and II water quality classes. The Sava Lake inhabits 20 fish species from 19 genera, belonging to 8 families. Among the registered taxa, 2 families, 4 genera and 6 species are allochthonous. Calculated diversity indices were 0.143, 2.451, and 0.818 for Simpson's, Shanon-Weiner, and Evenness index, respectively. The F/C ratio was estimated as 4.18 indicating balanced community structure. Ecological classification provided information on intracommunity structure beyond the taxonomical level.
