The article presents the results of studies of the fish fauna of the floodplain lake Sanderka, during which 15 species of fish were identified, which is 60% of the fish fauna composition common for the bayou waters of the Sura river. The species represented in the studied lake belong to the five faunal complexes. This indicates a preserved ecosystem of the lake, compared with other water bodies of this type. Of the 15 fish species identified in the lake Sanderka, five are valuable commercial fish. It has been established that the dominant species in the studied lake is roach, the rudd is also numerous, the number of bream is rather high. Despite the proximity of human settlements and thanks to the uniqueness of its ecosystem, lake Sanderka has preserved the biodiversity of the fish population. It can serve as a reference water body in the organization of monitoring studies of the fish fauna of the bayou lakes of the Penza Region and the Republic of Mordovia.
