Saprobic group (SG) distribution as biomonitoring tool - investigation of the Vlasina river watershed, SE Serbia, Yugoslavia

Abstract

The aim of this study was to explore the way for determination of environmental condition of running waters using macroinvertebrates. Water quality has been evaluated by using specific biological trait - saprobic group (SG) ratio. The macrozoobenthos of the Vlasina river and its two tributaries, the Gradska and Luznica rivers (south-east Serbia, Yugoslavia) was studied during 1996. A total of 125 taxa were identified. The 85 taxa were included in SG analysis and organized by saprobic values in four groups corresponding to saprobic zones. SG observation demonstrates good water quality and mild deterioration of water quality along the Vlasina river that was in co-ordination with results of physical and chemical analyses. It was underlined that SG analysis was a useful and easy to interpretative biomonitoring tool which can combined with the other community attributes to provide a full account of the understanding of the match between habitat and aquatic fauna.

Cilj ovog rada je da ispita mogućnost određivanja stanja tekućih voda uz upotrebu makroinvertebrata. Kvalitet vode procenjivan je uz korišćenje specifične osobine zajednice - odnos saprobnih grupa (SG). Makrozoobentos reke Vlasine i dve pritoke, Gradske reke i Lužnice ispitivan je tokom 1996. Determinisano je ukupno 125 taksona. Osamdeset pet vrsta uključeno je u analizu SG i svrstano u četiri grupe koje odgovaraju saprobnim zonama. Ispitivanja SG ukazuju na dobar kvalitet vode i blago pogoršanje kvaliteta vode duž reke Vlasine, što je u saglasnosti sa rezultatima analize fizičkih i hemijskih parametara. Podvučeno je da je SG analiza koristan metod biomonitoringa, koji se lako tumači i koji može biti kombinovan sa drugim osobinama zajednice, kako bi se obezbedilo celovito razumevanje odnosa staništa i vodene faune.
