Purpose: to study the state of water resources in the Southern Federal District, to consider the processes occurring in natural reservoirs in connection with the increasing anthropogenic load, to provide an evidence base for the use of the strain Chlorella vulgaris IGF No. С‑111 in the improvement of natural and artificial reservoirs, preventing the «bloom» effect. For the evidence base, field studies were carried out: sampling and analysis of water according to the following indicators: pH, total iron, manganese, phosphates, biochemical oxygen demand, chemical oxygen demand. The introduction of the Chlorella vulgaris strain IGF No. C‑111, grown at the VNIIOZ FGBNU according to the author’s method, was carried out from May to September 2019 at the rate of: 25 liters of suspension per 1 hectare of water surface area (at a culture density of 10 mln/ml). During the study, water resources in the Southern Federal District were studied; substantiated the importance of improving natural reservoirs with the help of biomelioration; the structure of biocenoses is presented, which has developed over many years under the influence of natural and anthropogenic factors; the introduction into circulation of the term – algobiomelioration is justified; the results of studies on the introduction of the Chlorella vulgaris IGF No. С‑111 strain into the ponds of the Volzhanka settlement of the Volgograd region to reduce the «blooming» effect are presented; shows the need for further research on the formation of sustainable biocenoses. It has been proved that the use of the algolization technology will allow to launch a mechanism for the rehabilitation of reservoirs, to strengthen the feed base of pond fish farming.
