 There is confusion when sexually mature silver bream and sexually immature bronze bream are cursorily compared in the field, because bronze bream grow to the same size as sexually mature silver bream very quickly whilst still very young, and when they are almost invariably a silver colour themselves.The maximum weight a silver bream varies with the habitat quality, but in optimum conditions can be 1.6 kilograms (3.5 pounds).Nevertheless, in normal conditions most silver bream never exceed 0.45 kilograms (1 pound), and in small ponds not even 0.3 kilograms.
