背的软条 (总数) : 7; 臀鳍软条: 7 - 9. Diagnosed from other Cyprinidae in Iberian Peninsula by the following characters: barbels absent; dark midlateral stripe from snout to caudal base; body slender, depth 3.8-4.4 times in SL; 37-42 + 2-3 scales on lateral line; mouth opening upward; and anal fin with usually 8½ branched rays (Ref. 59043).
Lives in schools in lowland rivers and lakes. Feeds on invertebrates, chiefly small crustaceans and insect larvae. Breeds in April-May among aquatic plants and on stony bottoms in shallow water. Threatened due to pollution, habitat destruction and the introduction of other species (Ref. 26100). The species is unique as it represents a stable all-male lineage nested within an almost all-female hybrid lineage (Ref. 49905).
生活在群游于低地的河川与湖泊。 繁殖于在水生植物之中的四月到五月与在浅水区中的多石底部上。 吃无脊椎动物, 主要地小型甲壳动物与昆虫幼生。 受到威胁的由于污染，栖息地破坏与其他鱼种的引入.(参考文献 26100) 此鱼种是独特的因为它代表被由一个几乎全部雌性的杂交子代所生产的一个完全都是雄性的世系。 (参考文献 49905)
Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔鱼
This species originated as a hybrid that is now recognized as a species and consists only of diploid males. The males mate with triploid females that are current hybrids. These females produce haploid eggs with chromosomes that are identical to those of the males. These matings apparently produce only males.歐洲: 葡萄牙與西班牙南部的河.(從 Duero ，塔吼河，瓜迪亞納與瓜達爾基維爾河下游, 參考文獻 32724) 在伯恩公約的附錄 3 中 (受保育的動物群).
