Climate / Range

Temperate; 2°C - 22°C (Ref. 27368); 62°N - 36°N, 10°W - 70°E

Eurasia: widely spread in Europe and middle Asia in the basins of the North, Baltic, Black, Caspian (from Emba, Ural and Volga to the rivers of the southern coast) and Aral seas (Ref. 33550). Introduced to several countries. Definitely absent in Siberia. Reports from this area arose from the confusion between the rudd and the roach (Ref. 1441). Several countries report adverse ecological impact after introduction.

Short description

Dorsal spines (total): 3; Dorsal soft rays (total): 8 - 9; Anal spines: 3; Anal soft rays: 8 - 12; Vertebrae: 36 - 39. Caudal fin with 18-19 rays (Ref. 2196)

Adults inhabit lakes, rivers, marshlands, canals and ponds where there is very little current. Omnivorous, feed on invertebrates (including insect larvae and adults) and plants. Although adults actively feed on macrophytes present in abundance in the environment, they are not an effective species for the biological clearing of weeds. Colorless or pale yellow eggs are found attached to vegetation in shallow water (Ref. 41678). Consumed fresh (Ref. 30578). Threatened due to the introduction of other species (Ref. 26100).
