Hur känslig är vild västkustlax Salmo salar för parasiten Gyrodactylus salaris? Ett fältförsök i Himleån, Varberg
Abstract The parasite Gyrodactylus salaris has recently spread to several new wild salmon rivers at the Swedish west coast. A study was carried out in River Himleån, infected in 2005, to investigate if the salmon population was negatively influenced by the parasite. In October 2007 salmon parr were captured by electrofishing. The fish were anaesthetized and their length and weight were measured.
