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).
Body shape (shape guide): fusiform / normal.
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).
出现于湖。 吃底栖的无脊椎动物,浮游动物与仔鱼。 产卵在十二月到二月。 在产卵之后,它离开沿岸区域而且停留在深水域中。 捕捉主要在冬天深度 25-50 公尺。 高度地评价而且通常是生鲜消费。 (参考文献 12290) 受威胁的由于捕捞过度与其他鱼种的引入.(参考文献 26100)
