Scientific Name:

Romanogobio uranoscopus

Species Authority:

(Agassiz, 1828)

Common Name/s:

English

–

Danube Gudgeon

Synonym/s:

Gobio uranoscopus (Agassiz, 1828)

Assessment Information [top]

Red List Category & Criteria:

Least Concern ver 3.1

Year Assessed:

2008

Assessor/s:

Freyhof, J. & Kottelat, M.

Reviewer/s:

Bogutskaya, N., & Smith, K. (IUCN Freshwater Biodiversity Unit)

Justification:
The species is widespread and still frequent in suitable habitats (fast flowing rivers) in the Danube drainage. However the species is particularly sensitive to pollution and damming and is locally threatened. It is suspected that the population has been declining and will continue to do so as more dams, particularly on small rivers, are built within the Danube basin, but not at a rate that will qualify the species for a threatened or Near Threatened category.

History:

Population [top]

Population:	Still frequent in suitable habitats in the Danube drainage. Though the population has declined, it is extirpated from the upper Danube (1830s).
Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	Habitat: Riffles of small, fast-flowing rivers and bottom of large rivers with water velocities of 0.7 m/s and more, stone bottom, in submontane zone. Young individuals prefer slow currents and shallow shoreline habitats with sand bottom. Spawns in shallow habitats with very high current (about 1 m/s). Biology: In laboratory, spawns several times between late May and mid-September, at temperatures above 11°C. Males wait for females at spawning sites. To spawn, both sexes move to surface or open water. Eggs drift with current, sink to bottom and then stick to substrate. Adults are nocturnal and solitary, juveniles are active at day. No data on food in the wild.
Systems:	Freshwater
