簡短描述
檢索表 | 型態特徵 | 形態測量圖
This species is distinguished from its congeners entering the freshwater of the Mediterranean basin by the following characters: an almost straight dorsal profile; thin gill rakers 38-72 (different populations average between 45 and 64); no teeth on palatine (Ref. 59043).
A lacustrine, pelagic species. Males reproduce for the first time at 2-3 years, females at 3-4; most reproduce only once or twice. Spawn at temperatures above 15-16°C in June to August, along the shores near the surface at night with bright moonlights. Adults feed mainly on cladocerans and copepods, also on small fish (Ref. 59043).
Most individuals reproduce only once or twice.歐洲與地中海。 湖科木湖， Garda ， Orta ， Magiore ， Lugano 與 Iseo.(義大利北部, 瑞士) 在湖 Bolsena ， Bracciano 與 Vico(中央的義大利) 引入。
