Description
Most river mouths from larger watercourses are today canalized or otherwise exposed to human intervention and there is a continuous pressure for coastal development in the remaining areas. Estuaries, defined as the transition zone between freshwater and seawater, are important habitats for anadromous brown trout (Salmo trutta), often termed sea trout. In this project, we tracked smolt and adult brown in river nidelva and nearby coastal areas. more

The purpose of the River Nidelva project is to monitor the migration of anadromous brown trout between river and fjord. Hatchery-reared sea trout are tracked in order to monitor their willingness to migrate to the ocean. Adult sea trout of wild origin are tagged and tracked for 14 months in order to map their movements between freshwater and saline habitats.
