The May Trout ( Salmo schiefermuelleri ) is a known and perhaps extinct fish species from the family of salmon fish (Salmonidae), based on ancient descriptions . It occurred in subalpine lakes in the catchment area of the Danube , for example in the Attersee , Traunsee and Fuschlsee in Austria, and possibly also in Lake Lucerne in Switzerland. There is no evidence for this species and its status is therefore doubtful. The common name refers to fishing in May when the species was found in shallow water, probably to spawn .
features
May trout reached a body length of up to 70 centimeters. The body was silvery with a black back and red spots on the flanks and X-shaped or angular black spots on the upper two-thirds of the flanks. The caudal fin was deeply indented.
Way of life
The species stayed in deep water for most of the year and only came to the lakeside to spawn in May. The eggs were white and about 2 millimeters in diameter. Fish served as food.
