The assessment of the ecological state of the reservoir in the Spring Valley of Volgograd

This paper presents a biological method for assessing the ecological state of water body. The reservoir Gypsy Pond, located in residential complex Spring Valley Sovetsky District Volgograd, was chosen as object research. In process reservoir, bioindication quality using algae according to T.Ya. Ashikhmina used. is quite simple and accessible its application. definition based on establishing degree organic pollution body by identifying indicators specific environment. According conducted studies, following species were found: Reinhardts Chlamydomonas (Chlamydomonas reinhardtii), diatoms (Diatomeae), green euglena (Egulena viridis), Ulothrix (Ulothrix), navicula (Navicula rhynchocephalia), chlorella (Chlorella vulgaris). As result, analyzed can be attributed highly polluted one, since dominant indicate strong contamination belong polysaprobic species. addition, result mixotrophic feeding viridis) chlamydomonas experiencing lack oxygen supply, production which occurs during photosynthesis, causes formation unfavorable conditions existence hydrobionts. It also important note that project currently being planned fill up studied body, have particularly negative impact current situation shortage fresh resources.
