簡短描述
檢索表 | 型態特徵 | 形態測量圖
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).
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).
一種生命期短的種是生活在湖中。 吃無脊椎動物。 受到威脅的由於棲息地破壞，污染而且捕撈過度.(參考文獻 26100)
