Distinguished from all its congeners in Balkan Peninsula by the following unique characters: usually 54-55 vertebrae (56-63 in other species of Salmo); and teeth on vomer extending to posterior-most end of shaft. Additional characters, but not unique, useful for its identification include the following: 100-114 scales along lateral line; 11-12 scale rows between lateral line and adipose; 2 supraorbitals; snout blunt, its length about equal to eye diameter; body plain yellowish silvery or with a few small, x-shaped pinkish dots; 18-22 gill rakers; and 25-29 pyloric caeca (Ref. 59043).
Occurs in lakes, from surface to about 20 m depth in summer and near shores in winter. Forms schools (Ref. 59043). Feeds on benthic invertebrates, zooplankton and fish larvae. Spawns in December-February. After spawning, it leaves the coastal areas and stays in deep water. Caught mainly in winter at depths of 25-50 m. Highly valued and usually consumed fresh (Ref. 12290). Threatened due to overfishing and the introduction of other species (Ref. 26100) and intentional hybridization that has been going for 50 years (Ref. 59043).
出現於湖。 吃底棲的無脊椎動物，浮游動物與仔魚。 產卵在十二月到二月。 在產卵之後，它離開沿岸區域而且停留在深水域中。 捕捉主要在冬天深度 25-50 公尺。 高度地評價而且通常是生鮮消費。 (參考文獻 12290) 受威脅的由於捕撈過度與其他魚種的引入.(參考文獻 26100)
