简单描述
检索表 | 型态特徵 | 形态测量图
Distinguished from congeners in Italy by its unique almost absence of dark spots on head. Differs further by the combination of the following characters: adults lacking parr-marks; and outside spawning season silvery, with few, very small dark spots on body; during spawning season, some males show a dark marbled color pattern (Ref. 59043).
Body shape (shape guide): fusiform / normal.
Lives in lakes at 100-200 m depth. Feeds predominantly on zooplankton. Also preys on other benthic invertebrates during summer. Spawns close to underwater springs at 50-300 m depths (Ref. 59043). Threatened due to habitat destruction, pollution and overfishing (Ref. 26100) and possibly due to the introduction of exotic Coregonus and Salmonidae (Ref. 59043).
一种生命期短的种是生活在湖中。 吃无脊椎动物。 受到威胁的由于栖息地破坏,污染而且捕捞过度.(参考文献 26100)
