Short description

Dorsal spines (total): 3; Dorsal soft rays (total): 7 - 9; Anal spines: 3; Anal soft rays: 7 - 10; Vertebrae: 42 - 48. Caudal fin with 19 rays (Ref. 2196).

Adults occur in creeks and fast flowing rivers, occasionally in lakes (Ref. 30578). Enter brackish water in the eastern Baltic. Feed on algae, bits of vegetation and various seeds that have fallen into the water (Ref. 9696). Also feed on worms, mollusks, crustaceans, and various insect larvae; large chub eat considerable numbers of small fish, such as chub, eels, dace, roach, gudgeon and minnows; also frogs, crayfish, voles and young water birds (Ref. 6258). Pale yellow eggs are found attached to gravel, weed and stones in flowing water (Ref. 41678). Popular with amateur sport fishermen. Can be caught with various baits and lures. The flesh is of mediocre quality (Ref. 38587).
