Within the comprehensive hydrobiological investigation of Grosnica water reservoir (Serbia, Yugoslavia) composition and dynamics of bacterioplankton, phytoplankton and zooplankton, as well as their seasonal successions were studied. The composition of plankton communities varies during the vegetation period in the function of the physicochemical features. Grosnica water reservoir with its microbial features belongs to the 1st-2nd class of bonity according to Kohl. The highest values pf bacterio- and zooplankton were recorded in August, while bruto primary production in September.

The river Timok with its watershed area is one of very imperilled running water on the territory of Serbia (Yugoslavia). By several years investigations of colonies bottoms (phytobenthos, microzoobenthos and macrozoobenthos) and plankton we have found the following: great diversity and specific phytobenthos and bottom fauna (frequency of certain taxa is considerably larger in relation to the other areas, and new taxa have been recorded). Stated specific structure of phytobenthos and bottom fauna have considerably reflected to right estimation of water quality of tested area.

Primary production of phytoplankton and diversity and biomass of zooplankton of the Sava reservoir (artificial lake), Serbia (Yugoslavia), was studied during the summer and autumn in 1996. The study results were compared with the research results by Perisic et al. (1984) obtained before the dredging of the lake bottom, when bottom sediments with macrophytes were removed. It was found that the water quality was improved in comparison with previous period.

During one-year examination of the Vlasina river and its main tributaries, the Luznica and Gradska rivers, Serbia (Yugoslavia), in May 1996, the samples were taken for biological and chemical analysis of the watercourse in the spring aspect. Sampling was performed on the five localities of the Vlasina river, and two tribute localities near the mouth thus including all critical points where the changes of physico-chemical water parameters and qualitative/quantitative biocenoses compositions due to the increasing anthropogenic influence could occur. Data on phytoplankton, zooplankton, periphyton and benthos were analysed together with the physico-chemical water parameters in order to determine communities composition and structure and bioindicator species. Based on these results the status of aquatic environment i.e. water quality, was evaluated.

Pujin, V. (Prirodno-matematicki fakultet, Novi Sad (Yugoslavia). Institut za biologiju) | Stojkovic, S. | Djukic, N. | Miljanovic, B. | Maletin, S. | Sekulic, A. | Teodorovic, I.
The investigations of qualitative and quantitative composition of plankton and the bottom fauna of the Tisza river, Serbia (Yugoslavia), were conducted during 1998. According to the analyses of the indicator species of hydrobionts, saprobic index was calculated, and the estimation of the water quality of the lower flow of the dam near Novi Becej on the structure and abundance of the investigated organisms.
