ABSTRACT
This work provides a retrospective and dynamic investigation of the variety of hydrobionts making the main taxonomic components in freshwater reservoirs of the Angarsky Sor Bay in the northern section of Lake Baikal in September 2020 (reconnaissance), July 2020 (reconnaissance), and August 2021. In 2020, high-quality zoobenthos samples were collected through reconnaissance employing ichthyofauna and deep zoning. The data on zooplankton were gathered and processed using the quantitative method. Based on a modified numerical classification, 24 species of phytoplanktons, dominant species of zooplanktocenosis, 25 taxonomic groups representing the zoobenthos species composition, and 14 species from ichthyofauna groups were identified. Depending on the rise in depth, quantitative zoobenthos indicators were identified at all depths of the littoral zone. Based on the analysis of literary sources, the taxonomic identification of phytoplankton at various sites is determined considering the individual volume of their cell mass. The counting method was used to aggregate and process quantitative and qualitative data on zooplankton of epilimnion, metalimnion, and the upper horizon of hypolimnion. The species structure of the system-forming complex of zooplanktocenosis in the context of rotifers, copepods, and branched crustaceans is determined. The dynamic and dominant structure of zooplanktocenosis by sectors of deep sites is analyzed. This study provides insight to researchers searching for interspecies diversity, particularly in Baikal Lake. Moreover, the proposed research provides apprehension of several phytoplankton, zooplankton, and zoobenthos species by performing wide-scale reconnaissance of the freshwater depths. This study also provides qualitative characteristics of benthic invertebrates' diversity and zoobenthos productivity in the reservoir. This article assists the researchers in contributing to the effective management of biological diversity conservation. Although there are studies on the diversity of hydrobionts, very limited data is present on dynamic and retrospective analysis of hydrobiont diversity in the Angarsky Sor Bay situated in the northern part of Lake Baikal.
