This year’s field season is underway and marine biologists from AquaBiota have recently returned from a fish survey close to the Eystrasalt bank, an exposed and shallow offshore area in the middle of the Bothnian Sea. The survey was carried out on behalf of wpd who wants to explore the possibilities of establishing a wind […]
Limnic environmental monitoring in Sundstatjärn
Sundstatjärn is a popular bathing lake in central Karlstad, that has been struggling with eutrophication for many years. Eutrophication gives rise to cyanobacteria during the warm months of the year. These blooms of cyanobacteria can in turn produce harmful toxins. To minimize the risks to humans and animals, Aquabiota on behalf of the Municipality of […]
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 […]
Two reports on the environmental impact and spatial needs of shipping
Shipping may impact marine conservation values in many ways. These two reports describe the current situation of maritime traffic in Kattegatt and at Salvorev, north of Gotland, and the impacts of the expected changes in traffic are investigated in terms of conservation values and shipping spatial needs. The reports are produced by AquaBiota Water Research […]
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 […]
Recommendations for design of monitoring programs
AquaBiota have conducted a compilation and review of monitoring programs for offshore wind power, financed by the scientific program Vindval. The report aims to answer the project objectives regarding review and evaluation of existing monitoring programs, list the environmental impacts identified, and to make recommendations for design of future monitoring programs. Wind farms in different […]
