Testing a New Biomarker Considering the Proportion of Embryos with Developmental Disorders in Gmelinoides fasciatus (CRUSTACEA: AMPHIPODA) Inhabiting Lake Onego (Republic of Karelia)

Key Points

The study aims to establish Gmelinoides fasciatus as a new biomarker for monitoring water pollution.
Observed embryos of Gmelinoides fasciatus for developmental disorders in Lake Onego.
Assessed the impact of pollutants on ecosystems through amphipod embryo state.
Identified developmental disorders in embryos of the invasive species Gmelinoides fasciatus.
Established the use of this species as an indicator for water pollution monitoring.

Abstract

The article discusses the developmental disorders observed in the embryos of an invasive species Gmelinoides fasciatus (Stebbing 1899) (CRUSTACEA: AMPHIPODA) inhabiting the Kizhi Island region of Lake Onego. It was already shown that the state of amphipod embryos may serve as an indicator for assessing the impact of pollutants on ecosystems. The results obtained in our study contribute to establishment of G. fasciatust as a new biomarker species that can be applied for the monitoring of water pollution.
