歐洲: 西班牙與葡萄牙; Duero ,塔吼河,瓜迪亞納與瓜達爾基維爾河.(參考文獻 32724) 在伯恩公約的附錄 3 中 (受保育的動物群).
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 4.3, range 4 - 4.5 cm
Max length : 25.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 556); common length : 15.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 556)
Diagnosed from its congeners by having usually 49-59 + 2-3 scales on the lateral line, 4½-7 scale rows between lateral line and pelvic origin, and eye diameter 1.0-1.5 times snout length (Ref. 59043).
Occurs in the middle reaches of streams with moderate current and abundant aquatic vegetation (Ref. 59043) and in the lower reaches of rivers with slow current and abundant submerged plants (Ref. 26100). Feeds on invertebrates, plants (Ref. 26100) and zooplankton (Ref. 59043). Spawns from March to May. Threatened due to water abstraction and the introduction of other species (Ref. 26100).
居住於河的中下游的一種生命期短的種, 且水流和緩水平面下植物豐盛的地方。 吃無脊椎動物與植物。 從三月到五月產卵。 受到威脅的由於水資源減少與其他魚種的引入.(參考文獻 26100)
