How to identify silver bream

Blicca bjoerkna · Leuciscidae

The characters that identify silver bream, ranked by how far each one can be trusted on its own.

A silver bream laid on weathered wood beside a centimetre rule showing it at about fifteen centimetres, in left profile, with a deep compressed silver body, a very large eye, and an orange-red flush at the base of the pectoral and pelvic fins.
Silver bream (Blicca bjoerkna). The two characters that separate it from a young common bream are both visible: the proportionally very large eye, and the reddish base to the paired fins.Identified by: Identified on the two characters separating Blicca bjoerkna from a juvenile Abramis brama, both legible: the eye is proportionally very large relative to the head, and the base of the pectoral and pelvic fins carries a distinct orange-red wash where a common bream's are grey. Deep body, long anal fin and forked tail are consistent with both and do no diagnostic work. The rule in frame gives roughly 15 cm, which is supporting evidence in itself.mikaelnyman — CC BY 4.0, via Wikimedia Commons — source, licence

Look at this first

Look at the eye against the snout. In a silver bream the eye is very large — roughly as wide as the snout is long — where in a common bream of the same size the eye is proportionally much smaller. Then check the base of the pectoral and pelvic fins for a reddish flush.

Diagnostic — settles it on its own

Each of these settles the identification on its own. If one is clear, you have your answer.

  • A proportionally very large eye

    The eye diameter is close to the length of the snout in front of it. In a common bream — including a young one of exactly this size, which is the confusion — the eye is distinctly smaller relative to the head. It is the most reliable single character available without counting anything.

Supporting — use with other characters

Real characters that are not conclusive by themselves. Use two or three together.

  • A reddish or orange flush at the base of the paired fins

    The pectoral and pelvic fins carry an orange-red tint at their base, strongest in fish in good condition. A common bream's paired fins are grey throughout. It is real, it is useful and it fades on a dead or stressed fish, which is why it sits second rather than first.

  • Large, clearly-defined scales

    Silver bream have noticeably larger scales than common bream, and the lateral-line scale count is lower — the count settles disputed fish and is worth learning for anybody fishing a water with both. Bringing a fish to a count is a specialist step and the page does not pretend otherwise.

Suggestive only — varies with condition

Hints only. These vary with condition, season, water and how long the fish has been out of it, and a fish that contradicts them is still the same species.

  • A bright silver flank without the bronze of an adult bream

    Silver bream stay bright silver throughout life. Common bream darken to a deep bronze as they mature — but a young common bream is silver too, which is exactly why the confusion exists. Useful only for excluding a large bronze fish, and worthless for the small silver ones.

What it gets confused with

  • Young common bream, which is the whole problem. Read the eye against the snout, then the base of the paired fins.
  • Roach × bream hybrids, which are intermediate in every character used here and are common in waters holding both.
  • Large roach, which is rounder in section with a red iris and a much shorter anal fin.

Side by side: Silver bream vs Common bream.

Where this stops working

Silver bream hybridise with roach, rudd and common bream, and hybrid populations are widespread in waters holding several of them. A proportion of the deep silver fish caught in such a water genuinely cannot be named by any field character, and this page will not name them. Where a fish matters — a record claim, a survey — the lateral-line scale count and the pharyngeal tooth arrangement are what settle it, and both require the fish in hand and someone who has done it before.
