The Starnberg whitefish ( Coregonus renke ) belongs to the genus of salmon fish (Salmonidae) in the subfamily of the Coregoninae . The species was described in 1783 as Salmo Renke by the German naturalist Franz de Paula von Knie . The freshwater fish is only found in a number of German and Austrian lakes.
features
The fish can be up to 29 cm long. It has dark spots on its pectoral and pelvic fins. The number of gill traps is between 30 and 40.
Habitat and way of life
The fish's habitat is limited in Germany to the Schliersee , Tegernsee , Starnberger See , Ammersee and Kochelsee and in Austria to the Traunsee and Hallstätter See . He reaches sexual maturity at the age of three. The fish spawns on gravel or stone floors from the bottom of the lake to near the beach. In Lake Hallstatt, it also spawns in smaller tributaries.
Danger
The Starnberger Renke was endangered by the introduction of sewage into Lake Starnberg until the 1960s. The introduction of other Coregonus species into the habitat of the Starnberg whitefish is also considered a threat. In addition, sufficient information about the current status of this species is missing. That is why the Starnberg whitefish is listed as data defincient on the IUCN red list .
