How to identify yellowfin bream

Acanthopagrus australis · Sparidae

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

Safety

Injury while handling fish — Minor injury

The stiff dorsal spines cause deep punctures when the fish is gripped carelessly, particularly when landing over rocks.

What reduces it: Grip across the body with the spines folded, use a wet cloth or lip grip, and unhook with pliers.

A yellowfin bream in side view over clean sand in shallow Queensland water, whole fish in frame, its pelvic and anal fins strongly yellow against a silver flank ruled with faint horizontal lines along the scale rows, with a yellow wash on the lower tail lobe and a dark trailing edge to the tail. — Yellowfin bream (Acanthopagrus australis) over sand at Inskip Point, Queensland. Yellow pelvic and anal fins, and a yellow wash low in the tail — a black bream in the same estuary has dusky fins instead.Identified by: The record's character survives the water and is unmistakable: the pelvic and anal fins are strongly YELLOW against a silver flank, with a yellow wash on the lower caudal lobe. That is what separates this from the dusky-finned black bream Acanthopagrus butcheri which shares the same estuaries. Faint horizontal lines along the scale rows, dark caudal margin and the large eye all read.Rolf Lawrenz — CC BY, via iNaturalist — source, licence

About the image above: The photograph is an in-water frame shot through a metre of warm-tinted water. The fin yellow the page leads on is strong enough to survive that; nothing else about the tone in the image should be relied on.

Look at this first

Turn the fish belly-up and look at the pelvic and anal fins. On a yellowfin bream they are properly yellow, and there is usually a yellow wash low in the tail as well. On the black bream that shares the same estuaries those fins are dusky grey. Then check between the eyes, where a yellowfin bream carries no gold band.

Diagnostic — settles it on its own

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

Yellow pelvic and anal fins
The paired fins under the body and the anal fin behind them carry real yellow, and in a fish in condition the lower lobe of the tail is washed with it too. Black bream's are dusky to grey-black. This is a colour and it is admissible here because it is strong, because it holds on a fish in the water and a fish in the hand, and because the alternative characters separating these two congeners are worse. It does fade after death.

Supporting — use with other characters

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

No gold band between the eyes
Look across the top of the head. Tarwhine, which is the other bream a reader will meet in the same water, carries a distinct gold or bronze band between the eyes and gold horizontal lines along the flank. Yellowfin bream carries neither. It is an absence, which is a weaker instruction, so use it as the second check rather than the first.
Incisor-like front teeth with molars behind
Open the mouth. The front of the jaw carries flattened cutting teeth and the back carries rounded crushing molars — the apparatus of a fish that eats crabs, prawns and shellfish. This places the animal in the breams and away from the trevallies and whiting of the same flats, and it is worth seeing because it explains the whole of the species' behaviour.
A deep compressed silver-grey body with faint longitudinal lines
The body is deep, flattened side to side, silver-grey with a darker back and fine horizontal lines following the scale rows. It is the standard Acanthopagrus silhouette. Recognising it gets you to the genus quickly and settles nothing within it.

What it gets confused with

Black bream, Acanthopagrus butcheri, which shares the estuaries in the south of the range and has dusky rather than yellow paired fins.
Tarwhine, which is separated by the gold band between the eyes and the gold flank lines, and which has a blunter snout.
Yellowfin × black bream hybrids, common where the two ranges overlap in southern New South Wales and Victoria, which carry intermediate fin colour.
Pikey bream in the north of the range, a further Acanthopagrus that overlaps and is genuinely difficult.

Where this stops working

Yellowfin bream and black bream hybridise freely where their ranges meet along the south-eastern Australian coast, and hybrid populations are established in several systems. In those waters fin colour is intermediate and unreliable, and no field character resolves it. Fin yellow also dulls after death and can be weak in fish from dark tannin-stained water, so a bream from an upstream reach with grey-looking fins is not necessarily a black bream. In the north of the range further Acanthopagrus overlap and the separation becomes a specialist question. Size and bag rules for bream differ by state and change; the current rules of the state fisheries authority are the only source for what a reader may do with one.
