بوم شناسي
; آب شيرين; لب شور نزديك كف زي; pH range: 7.0 - 7.5; dH range: 10 - 20; رود رو (Ref. 51243). Temperate; 2°C - 20°C (Ref. 1672); 73°N - 37°N, 10°W - 179°E
Eurasia: basins of Atlantic, North and Baltic Seas, Arctic and northern Pacific Ocean, from Garonne (France) eastward to Anadyr and Amur drainages and Korea; Ireland (possibly introduced), Great Britain northward to 58°N. Scandinavia and Russia northernmost extremity, Rhône drainage. Recorded from upper and middle Volga and Ural drainages, Lake Balkhash (Kazakhstan) and upper Syr-Darya drainage (Aral basin), but else identifications need verification. At least one country reports adverse ecological impact after introduction. Several species are confused under Phoxinus phoxinus.
Length at first maturity / Size / Weight / سن
بلوغ: Lm 5.2, range 5 - 5.8 cm
Max length : 14.0 cm TL جنس نر / بدون خواص جنسي; (Ref. 556); common length : 7.0 cm TL جنس نر / بدون خواص جنسي; (Ref. 556); بيشينه سن گزارش شده: 11 سال ها (Ref. 59043)
خارهاي باله پشتي (کل) : 3; شعاع نرم باله پشتي (کل) : 6 - 8; خارهاي باله مخرجي: 3; شعاع نرم باله مخرجي: 6 - 8; مهره ها: 38 - 40. Diagnosed from its congeners in Europe by having lateral line usually reaching beyond anal fin base, a midlateral row of vertically elongated blotches whose depth is about 1/3-1/2 of body depth at same position, often fused in a midlateral stripe (in preserved individuals), caudal peduncle depth 2.6-3.1 times in its length, patches of breast scales separated by unscaled area or (rarely) connected anteriorly by 1-2 rows of scales, snout length 29-34% HL ( 1.1-1.4 times eye diameter), and anal fin origin in front of base of last dorsal ray (Ref. 59043). Caudal fin with 19 rays (Ref. 2196).
Body shape (shape guide): elongated.
Gregarious (Ref. 2196). Found in a wide range of cold and well oxygenated habitats from small, fast-flowing streams to large Nordic lowland rivers and from small upland lakes to large oligotrophic lakes. Usually occurs in association with salmonid fishes (Ref. 59043). Feeds on algae, plant debris (in rivers), mollusks, crustaceans and insects (Ref. 30578). Spawns over clean gravel areas in flowing water or on wave-washed shores of lakes. Overwinters in coarse substrate or in deep pools with low current (Ref. 59043). Migrates upstream for spawning in shallow gravel areas. Important laboratory fish, for research on sensory organs of fishes. Mean maximum age is 6 years (Ref. 41616). Locally threatened due to pollution and excessive stocking of species of Salmo (Ref. 59043).
Males and females form school separately and arrive on the spawning site at differen times. Spawn over clean gravel areas in flowing water or on wave-washed shores of lakes. Deposit eggs in shallow water on sand or gravel bottom which hatch in 4-5 days at 18°C. Females lay sticky eggs deep into clean gravel (Ref. 59043).

Estimates based on models
Phylogenetic diversity index (مرجع
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00497 - 0.00963), b=3.14 (3.05 - 3.23), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trophic level (مرجع
69278): 3.2 ±0.4 se; based on diet studies.
Generation time: 4.0 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
