Cobitidae (Spined loaches)
Etymology: Cobitis: Greek, kobitis, -idos = a kind of sardine; also related with the voice Greek, kobios, Latin gobius = gudgeon (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Écologie
; eau douce benthopélagique. Temperate
Europe and Asia: Northern and western Black Sea basin (from Danube to Kuban drainages). Restricted to the lowermost part of Danube, Dniestr and Kuban drainages. More widespread in South Bug and Dniepr drainages. Occurrence is expected in some part of the Baltic basin (Vistula and Odra drainages) (Ref. 59043).
Taille / Poids / Âge
Maturity: Lm ? range ? - ? cm
Max length : 6.0 cm SL mâle / non sexé; (Ref. 59043); 9.5 cm SL (female)
Épines dorsales (Total): 2 - 3; Rayons mous dorsaux (Total): 7-8; Épines anales 1-3; Rayons mous anaux: 5 - 7. Pigmentation (Gambetta's longitudinal zone of pigmentation): zone Z3 usually ending under dorsal base in male; one black spot at caudal base, about size of pupil or eye, oval or round; zone Z3 usually narrower than zone Z2. One lamina circularis. Cannot be distinguished from sympatric hybridogenous species using external characters (Ref. 59043).
Found in large coastal lakes and lower part of rivers on silt bottom, as well as smaller streams with sand bottoms (Ref. 59043). Adults migrate to larger water bodies in autumn for overwintering (Ref. 59043). Oviparous, possibly with distinct pairing during breeding similar to congeners (Ref. 205).
Life cycle and mating behavior
Maturité | Reproduction | Frai | Œufs | Fécondité | Larves
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).
