Göta älv is Sweden's largest watercourse and is utilised for various purposes. It serves as a source of drinking water, is used by industries for cooling and processing water, acts as a recipient for wastewater, supports power generation, and functions as a shipping channel. Human exploitation of the river has negative impacts on aquatic ecosystems.
The aim of the project has been to gather knowledge about the distribution of all major freshwater mussel species in the Göta River's water system, from Lake Vänern to the sea. Significant knowledge gaps exist regarding the distribution of mussels in Sweden, particularly for the more commonly occurring species.
