Abstract. An important place in the biomonitoring research belongs to phytoplankton. This is important because it shows the ecological status of water bodies and it is used for planning and environmental protection. Study of structural and functional characteristics of phytoplankton, identifying the main features of its development in the various ecosystems of origin reservoirs Volgograd region were objectives of our research. Investigations were carried out near the village Volzhanka of Sredneakhtubinsky district of the Volgograd region. Samples were taken every month for 2010-2013 from April to October at the following points: full-system pond farm “Flora” (pond no. 1, pond no. 5, pond no. 7), Biruchiy bay of the Volgograd reservoir, artificially created by the beam, which has no connection to the reservoir. Investigations were carried out according to GOST 17.1.4.02-90 (1999) and Guidelines (1983), according to G.G. Vinberg [13]. The studies show that the level of phytoplankton in the water gradually increased since April, peaking in August, then gradually decreases and the end of October has a minimum value. Average spring phytoplankton biomass levels ranged from 0.7644 to 2.7882 mg/L; in summer – from 3.5923 to 53.9616 mg/L; in autumn – from 3.5870 to 10.2592 mg/L. There is a positive relationship between the level of biomass and chlorophyll a in the test water samples. The level of phytoplankton biomass increases when increasing the value of chlorophyll a. We discovered 46 species and varieties in the composition of phytoplankton from July to October of 2013. They fall into five departments: Diatomeae – 17, Cyanophyta – 10, Chlorophyta – 14, Euglenoidea – 3, Cryptophyceae – 2. We determine the dominant taxa: Diatomeae – Aulacoseira granulata, Nitzschata angustata, Chlorophyta – Chlorella vulgaris, Pandorina morum, Cyanophyta – Microcystis aeruginosa, Anabaena contorta.
Key words: phytoplankton, algocoenosis, chlorophyll, biomass, algomonitoring.
