背的軟條 (總數): 7; 臀鰭軟條: 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).
生活在群游於低地的河川與湖泊。 繁殖於在水生植物之中的四月到五月與在淺水區中的多石底部上。 吃無脊椎動物, 主要地小型甲殼動物與昆蟲幼生。 受到威脅的由於污染，棲息地破壞與其他魚種的引入.(參考文獻 26100) 此魚種是獨特的因為它代表被由一個幾乎全部雌性的雜交子代所生產的一個完全都是雄性的世系。 (參考文獻 49905)
Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
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).
