Thanks to the Sommen characteristic with several narrow straits, shallow bays, large pelagic areas, depths and different nutritional status in the eastern and western basin, there is room for many fish species (ie many potential niches). The lake is a nutrient-poor lake, which is why it doesn't have that many carp species (known as cyprinider).
The fish species in the sea have, according to various studies and independent data, previously been declining. The Sommen FVO see it as one of their most important tasks to protect the lake's unique biodiversity and stop this development.
