Still frequent in Lake Traunsee (25 km²). Hybridisation has been shown to occur (over the past 30 years) with introduced coregonids but it is not thought to cause a decline in the number of mature individuals of C. danneri as the hybrids seem to rarely survive. There is a potential threat of the introduction of other coregonids which may have a negative impact.
