Freshwater pearl mussels Margaritifera margaritifera in Boelva River, Telemark Population, pearl fishing and nacre decoration on Hardanger fiddles Elvemuslingen i Boelva, Telemark Bestand, perlefiske og perlemor pa hardingfeler
For several hundred years Boelva River has been known for its population of freshwater pearl mussels Margaritifera margaritifera (L., 1758). Fiddlemakers used the mussel nacre in their decoration of Hardanger fiddles, and in the past pearl fishing was a common occupation in the river. The article presents a historical survey of these circumstances. These activities, together with pollution and regulations of the river, have decreased the mussel population. An investigation in 1995-96 estimated the whole mussel population in the 35 km long river basin to about 5000 individuals. A possible future power plant construction may decrease the population even more.
