PHYTOPLANKTON CONTENTS, PHYSICO-CHEMICAL CHARACTERISTICS AND TROPHIC STATUS OF ĆELIJE RESERVOIR

Snežana ČAĐO, Aleksandra ĐURKOVIĆ and Aleksandar MILETIĆ^[1]

Synopsis

This paper presents the results of the phytoplankton analysis and the analysis of physico-chemical characteristics of Ćelije reservoir which is used for water supply of town of Kruševac. According to the programme of the systematic examination of surface water quality carried out by the Republic Hydrometeorologic Service of Serbia, the sampling has been done in September 2002 and 2003 on three localities: at the dam, in central part and at the entrance of reservoir on three depths. The presence of 87 phytoplankton taxa of seven algal divisions has been established on the basis of qualitative analysis. The silicate algae are dominant, comparing to taxa number, whilst the green algae are subdominant.

Key words: Phytoplankton, nutrients, trophic status.

Sinopsis

SASTAV FITOPLANKTONA, FIZIČKO-HEMIJSKE KARAKTERISTIKE I TROFIČKI STATUS AKUMULACIJE ĆELIJE

U radu su prikazani rezultati analize fitoplanktona i fizičko-hemijskih karakteristika akumulacije Ćelije koja se koristi za vodosnabdevanje grada Kruševca. Prema programu sistematskog ispitivanja kvaliteta površinskih voda RHMZ-a Srbije uzorkovanje je obavljeno u septembru 2002. i 2003. godine na tri lokaliteta: kod brane, u centralnom delu i na ulazu u akumulaciju na tri dubine. Kvalitativnom analizom fitoplanktona utvrđeno je prisustvo 87 taksona iz sedam razdela algi. Silikatne alge su dominantne, u odnosu na broj taksona, dok su subdominantne zelene alge.

Ključne reči: fitoplankton, nutrijenti, trofički status.
