Europe: Aegean and Black Sea basins, from Struma drainage to area of Varna (Greece, Bulgaria, Turkey), Lakes Volvi and Koronia (Greece); Danube basin in Bulgaria. In Danube and Struma drainages, C. strumicae occurs together with hybridogenous, sprem-parasitic lineages, which have originated by hybridisation of C. elongatoides with C. taenia or C. tanaitica (Ref. 59043).

簡単な記述
検索表 | 形態学 | 形態計測学
Presence of a black spot at caudal base, very small or sometimes absent, rarely two small spots. Pigmentation (Gambetta's longitudinal zone of pigmentation): zone Z4 with 12-21 roundish or squarish blotches, sometimes indistinct or fused two by two; flank not pigmented below zone Z4. Two laminae circularis.
A short-lived species. Adults occur in highland and lowland water courses with little current, in springs and associated wetlands and in lakes (Ref. 26100), with sand or silt bottom (Ref. 59043). Oviparous, with distinct pairing during breeding (Ref. 205).
Life cycle and mating behavior
成熟 | 繁殖 | 放精 | 卵 | 生産力 | 幼生
During courtship, 'the male follows the female and, after both enter dense vegetation (e.g. filamentous algae), the male forms a complete ring around the female's body behind the dorsal as the female releases the eggs' (Ref. 59043).
