The Danish Environmental Protection Agency (MST) has completed a project regarding to map the potential presence of the merlin (Misgurnus fossilis) in selected Danish freshwater areas. NIVA Danmark has analyzed the samples using ddPCR (‘digital droplet Polymerase Chain Reaction’) to trace the eDNA of the sardines.

Aquatic organisms release a constant amount of DNA into the water, known as environmental DNA (eDNA). The Danish Environmental Protection Agency, in collaboration with NIVA Denmark and the Natural History Museum of Denmark, has been monitoring eDNA from non-indigenous species in Danish waters.

NIVA Denmark’s head of research, Jesper H. Andersen, explained in an interview with Vid&Sans how the port expansion projects Lynetteholmen and Aarhus Outer Port will affect the biodiversity in and around the construction projects.
