Type: freshwater

Physical Characteristics
A disk-shaped, laterally compressed body with silver scales on the sides and a greenish-grey back. It features a relatively blunt snout, large eyes, and reddish or orange tints at the base of the pectoral and pelvic fins. The anal fin is shorter than that of the common bream.
Habitat & Distribution
Primarily found in slow-flowing rivers, canals, and lakes across Europe and Western Asia. Prefers shallow, nutrient-rich waters with muddy bottoms and plenty of submerged vegetation.
Size & Weight
Standard size is typically 15–25 cm in length, weighing between 0.2–0.5 kg. Maximum recorded size can reach up to 45 cm and approximately 1 kg.
Similar Looking Species
The Common Bream (Abramis brama), which has smaller eyes, darker fins, and more scales along the lateral line, and the Roach (Rutilus rutilus), which has a more cylindrical body and redder eyes.
Ecological Role
Acts as a benthic feeder, consuming small crustaceans, insect larvae, and mollusks from the sediment. It serves as a prey species for larger predatory fish like pike and perch. The species is currently listed as 'Least Concern' by the IUCN.
