The tissue sampling was approved by the Veterinary Office of the Bern canton (approval number BE188/14). The invasive fin biopsy was classified by this Veterinary Office as degree of severity 1 (on the scale from 0 to 3) while the catching of wild adults, the keeping of these animals for some days at the Fischereistützpunkt Reutigen, and the collection of gametes was part of the cantonal routine breeding for the annual stocking and was therefore not considered part of the experiment.
