Black drum vs Sheepshead

How to tell them apart, and what follows from getting it right.

Why they get confused

A juvenile black drum carries bold dark vertical bars over a pale flank, and so does a sheepshead at every size. They occupy the same bridges, pilings, jetties and oyster bars along the whole south-eastern and Gulf coast, both feed on shellfish, and both are caught on the same crab and shrimp baits by anglers fishing the same structure. The bars are what people see first and they are the character shared rather than the character that separates.

Black drum

Pogonias cromis — Sciaenidae

A juvenile black drum photographed in lateral view on a plain background, showing a deep high-backed silver body crossed by four or five broad dark vertical bars, and a row of short barbels beneath the chin.
Black drum (Pogonias cromis), a juvenile of about 81 mm from the South River, Maryland. The bold vertical bars are a juvenile character and fade with age — an adult black drum is plain dark grey.

Sheepshead

Archosargus probatocephalus — Sparidae

A sheepshead held up on a hook against a blue sky, deep-bodied and strongly compressed, with five bold dark vertical bars over a pale flank, a steep forehead, heavy sharp spines along the front of the dorsal and anal fins, and the mouth open on broad flat pale front teeth.

The differences

Each difference is marked with how far it can be trusted on its own. A single diagnostic character settles the identification; suggestive ones only narrow it.

Differences between Black drum and Sheepshead
CharacterBlack drumSheepsheadReliability
Barbels under the chinIdentificationA fringe of short barbels runs along the underside of the lower jaw. Run a finger there and you cannot miss them.Nothing at all under the chin. Smooth jaw.Diagnostic on its own
Teeth at the front of the jawIdentificationThe mouth is inferior, set under the snout, and unarmed — the crushing teeth are in the throat where you cannot see them.Broad flattened incisors at the front of the jaw, unnervingly human-looking, with heavy molars behind them.Diagnostic on its own
What happens to the bars with ageIdentificationThe bars fade with growth; a large black drum is close to uniformly dark grey or bronze-black.The bars persist through life, blurring somewhat in very large old fish but remaining recognisable.Supporting — use with others
Body profileIdentificationHigh-backed and heavily humped behind the head, with the deepest point well forward.Deep and strongly compressed with a steeply sloping forehead, but not humped in the same way.Supporting — use with others
The size you are likely to be holdingSizeCommonly 2–8 kg, with fish of 15–25 kg regular and exceptional fish past 35 kg.Commonly under 2.5 kg, with a very good fish 3.5–6 kg. A barred fish over about 10 kg is a black drum.Supporting — use with others
Handling injury riskHandlingBulk is the problem: a large drum should be supported horizontally and not lifted vertically by the jaw.Spines and jaws: stiff sharp dorsal and anal spines puncture deeply, and the crushing jaws can injure a finger placed in the mouth.Supporting — use with others

Why it matters

Both are size-limited and bag-limited across the Gulf and south-east, and the limits are not the same — several states operate slot limits on black drum specifically to protect the very large old females, and sheepshead carries its own minimum size and bag. Verify the current rules with the responsible state authority before retaining either. There is a table consequence as well: very large black drum are commonly reported to carry parasites in the flesh and are widely regarded as poor eating compared with fish in the slot, while sheepshead of any size is excellent but is awkward to fillet around the heavy ribcage.
