Description

The bream is usually long, though some specimens of have been recorded; it usually weighs . Its maximum length is 90 cm (35.5 in),the recorded weight is around 9.1 kg (20 lb). The common bream has a laterally flattened and high-backed body and a slightly undershot mouth. It is a silvery grey colour, though older fish can be bronze-coloured, especially in clear waters. The fins are greyish to black, but never reddish.

Similar-looking fish

The common bream can easily be confused with the silver or white bream (''Blicca bjoerkna''), in particular at the younger stages (see picture). The most reliable method of distinguishing these species is by counting the scales in a straight line downwards from the first ray of the

Like other Cyprinidae, common bream can easily hybridise with other species, and hybrids with roach (''Rutilus rutilus'') can be very difficult to distinguish from pure-bred bream.Giles, Nick, ''Freshwater Fish of the British Isles: A Guide for Anglers and Naturalists'', Swan Hill Press, 1994, , pp 140–144

Habitat

The common bream generally lives in rivers (especially in the lower reaches) and in nutrient-rich lakes and ponds with muddy bottoms and plenty of algae. It can also be found in brackish sea waters.

Feeding habits

The common bream lives in schools near the bottom. At night common bream can feed close to the

is used up. Because of their slender shape, the young fish are often not recognised as bream, but they can be identified by their flat bodies and silvery colour. At this stage, the fish are still pelagic, but after a few months, they acquire their typical body shape and become bottom-dwellers. By three to four years old, the fish are sexually mature.

Fishing

The freshwater bream is not generally caught for consumption. Common Bream are popular with sport and match fishermen. However, bream are not as hard fighting as most other fish native to the UK, as due to their flat, disc-shaped profile they are relatively easy to bring to the bank. Bream will eat most baits, especially: * Sweetcorn - two or three grains hooked or hair-rigged. *
