In August 2018, AquaBiota performed an eDNA inventory of fish species in lake Båven (surface area 64,2 km²) in the county of Sörmland, commissioned by the water management association in Nyköping (Nyköpingsåarnas Vattenvårdsförbund). Eighteen fish species were found in the lake, including the threatened sheatfish (Silurus glanis) that during the time of sampling had sought out […]
eDNA-inventories as decision support in Environmental Impact Assessments
In cooperation with Tyréns and Sweco Rail, AquaBiota surveyed amphibians and fish using aquatic eDNA and metabarcoding (multi-species analysis), to support their work with environmental impact assessments. The data will be used in development planning for an extension of the Skelleftehamn harbour area, and impact assessment of the construction of a two-way railroad between Helsingborg […]
eDNA provides facts about the effects of hydropower plants
Fish fauna upstream and downstream Spjutmo hydropower plant in Dalarna was investigated using aquatic eDNA and metabarcoding. The survey was made by AquaBiota on behalf of Fortum Sweden. The results from this study can be used to suggest suitable measures for lake Spjutmo as part of Sweden’s undertakings regarding green infrastructure. Österdalälven above lake Spjutmo. […]
eDNA-analyses in Svartån
Using environmental DNA (eDNA) in a study on fish species diversity in Svartån, Östergötland in Sweden proves the method to be promising in monitoring programs of rare, elusive and invasive species. This particular stream is regarded to have a high species diversity. Sampled eDNA revealed presence of 21 fish species, another 4-5 species are expected […]
