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

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: *

They are not shy fish. Float fishing on the bottom is another technique used. Ledgering (using just a lead weight to hold the bait down) with a cage feeder full of bait, often works better on larger rivers and lakes. the current world record common bream, caught with rod & reel, is , caught in the United Kingdom.
