Key Points

This research aims to document the presence of the invasive amphipod Gmelinoides fasciatus in the Vygozero Reservoir.
Conducted studies of littoral bottom biocenoses in the Vygozero Reservoir, Lake Voitskoe, and Segezha River in June 2025.
Examined locations near shipping routes to identify the presence of G. fasciatus.
Gmelinoides fasciatus was detected at several littoral stations.
The species appears to be rapidly dispersing from its native habitat, suggesting potential full colonization of the Vygozero littoral zone in the near future.

Abstract

Abstract The Vygozero Reservoir is located in the Subarctic territory, the north of the European part of Russia, and is a component of the White Sea–Baltic Waterway. The results of studies of the littoral bottom biocenoses of the Vygozero Reservoir, Lake Voitskoe and the Segezha River in June 2025 are presented. It is shown that the invasive species Gmelinoides fasciatus (Stebbing 1899) (Crustacea: Amphipoda) was identified at littoral stations located close to shipping routes. The fairly rapid dispersal of the Baikal species G. fasciatus to the littoral of other water bodies gives reason to assume that in the coming years these amphipods may colonize the entire littoral zone of the Vygozero Reservoir.
