Overvåkingsprogrammet for Gyrodactylus salaris i settefiskanlegg og elver

Overvåkingsprogrammets gir oversikt over hvor Gyrodactylus salaris ikke forekommer i norske vassdrag, samt avdekker spredning av parasitten på et tidlig stadium.

2024

In 2024, a total of 2370 specimens of Atlantic salmon from 71 rivers and 3566 specimens of Atlantic salmon and rainbow trout from 97 hatcheries/farms were sampled and examined in the surveillance program for Gyrodactylus salaris.

The parasite was not detected in any of these samples. However, G. salaris was detected in a new water course, Bergerelva (watercourse code 012.3Z), in samples taken outside the surveillance programme. Samples from Bergerelva were examined during an investigation into the infection status in the Drammen region in relation to the upcoming treatment of rivers in this region.
