Common Bream

The common bream (Abramis brama) is a deep-bodied, laterally compressed cyprinid fish widespread across rivers, lakes, and canals of Europe and western Asia. Juveniles are silvery, but adults develop a distinctive bronze to golden-brown coloration on the flanks, giving rise to the alternative name bronze bream. Bream have a small head relative to their tall body and a protrusible, tube-like mouth that extends downward to probe soft sediment for food. They form large shoals, particularly in slow, nutrient-rich lowland waters, and are an important species for coarse anglers across Europe. Bream tolerate low oxygen and turbid conditions well, often becoming the dominant fish species in eutrophic lakes and slow canals.

• Very deep, thin, laterally compressed body with a small, narrow head
• Bronze-brown to golden flanks in adults; juveniles are more silvery
• Long-based anal fin, notably longer than the dorsal fin base
• Small, protrusible mouth that extends downward like a tube for bottom feeding
• Look-alikes: silver bream (Blicca bjoerkna) is smaller with larger eyes and a shorter anal fin; roach x bream hybrids show intermediate body depth and coloration

Common bream are native across much of Europe and western Asia, found in slow-flowing rivers, canals, and both natural and artificial lakes, with a strong preference for still or slow-moving, nutrient-rich water. They favor soft, silty or muddy bottoms where they can probe for food, and are often associated with deeper, turbid stretches of lowland rivers and eutrophic lakes. Bream tolerate low oxygen levels and warm summer temperatures better than many other cyprinids, allowing them to dominate in heavily enriched waters where competing species struggle. They are frequently found in large shoals that patrol specific feeding areas, often described by anglers as 'bream holes' or established feeding grounds.

Common bream are bottom-feeding omnivores, using their protrusible mouth to probe soft sediment for bloodworms, other insect larvae, mollusks, crustaceans, and plant material, often leaving characteristic feeding pits in soft mud. They are strongly shoaling fish, especially as they mature, forming large, tightly grouped schools that move together between feeding and resting areas, often at predictable times of day. Spawning occurs in late spring to early summer in shallow, weedy margins, where large aggregations of bream engage in noisy, splashing group spawning, with females depositing adhesive eggs on submerged vegetation and no parental care afterward. Bream can live for well over a decade and continue growing throughout their lives, with older individuals becoming increasingly deep-bodied and darker in color.
