Friskmeldingsprogrammet for Gyrodactylus salaris

In 2025, which was the first year of the post-treatment surveillance program for Gyrodactylus salaris in the Driva infection region, 498 salmon juveniles from the rivers Driva (109.Z), Batnfjordselva (108.3Z), Litledalselva (109.5Z), Usma (109.4Z), and Gylelva (109.7Z) in Møre og Romsdal county were surveyed. In addition to the standard surveillance where salmon juveniles are sampled by electrofishing and examined under a stereo microscope, environmental DNA monitoring was also carried out. Gyrodactylus salaris was not detected in any of the samples taken in the surveillance program.
