The Hägling ( Coregonus heglingus ) is a freshwater fish from the subfamily Coregoninae .
features
Like other members of the Coregoninae subfamily, the Hägling has a herring-like appearance with numerous small, silvery round scales . He also has an adipose fin . The Hägling reaches a maximum length of 240 mm.
distribution
The Hägling is endemic to Lake Walen and Lake Zurich in Switzerland . At the moment there is only a homogeneous population of Häglingen in both lakes . Up until 50 years ago, however, there were still two populations in the Walensee, one of which was spawned in summer and the other in winter. Probably in the course of the destruction of spawning grounds, temperature changes and the penetration of fish from Lake Zurich, the three populations were mixed.
Way of life
The Hägling feeds mainly on zooplankton and lives pelagic , but also swallows water snails and comparable organisms every now and then. The spawning season is in July in Lake Zurich and in late autumn in Lake Walen.
Endangerment and Use
Since the exact status of the haggling is uncertain, little can be said about its endangerment. It is a delicious food fish .
