Using drop-video AquaBiota has investigated the conservation values at Klints Bank east of Gotland. The number of occurring species was very limited and the dominating organisms were blue mussels and hydrozoans. Mussel beds occurred at 40% of the stations, and were more common in shallower areas where hard substrate occurred to a greater extent. The […]
eDNA detects 84 fish-populations in ten Swedish coastal watercourses
In February 2017 AquaBiota monitored fish-communities in ten coastward discharging rivers in northern Sweden, by using eDNA (environmental DNA metabarcoding). From each waterbody a few litres of water was collected and subsequently analysed for traces of fish DNA in order to identify the different species. Historical data from electrofishing spanning over 30 years was compared […]
Monitoring of crayfish and large freshwater clams using water samples
AquaBiota now offers monitoring of crayfish and large freshwater clams using eDNA. A few liters of water from a lake is enough to detect the presence of the critically endangered noble crayfish or the introduced signal crayfish. Being a vector of the crayfish plague the signal crayfish constitutes a serious threat to the native noble […]
Inventories of nature values in Lidingö
AquaBiota performed a marine conservation value assessment and extensive field surveys of the coastal waters off Lidingö for Lidingö Municipality’s work with a “blue plan”. Lidingö has launched a project to increase knowledge of the municipality’s aquatic nature values. This knowledge is necessary in municipal planning to highlight conservation values, threats and opportunities for development. […]
