Weakfish

Fish · Last reviewed 2026-08-10

A purple-sheened Atlantic drum named for its fragile mouth rather than any lack of fight, and a species whose stock has declined sharply.

Safety

Injury while handling fish — Minor injury

The two upper canines cause cuts to fingers during unhooking.

What reduces it: Grip across the body rather than by the jaw and use pliers or a dehooker.

Weakfish is named for its mouth. The membrane is thin and tears easily, so hooks pull out under pressure — nothing to do with the fish's strength, which is considerable.

It is a drum of the American Atlantic coast, iridescent purple-green above with gold and green flecking along the flank, and it hunts shrimp and small fish in estuaries, bays and surf. Like other sciaenids the males drum audibly during spawning.

It is also a genuine conservation concern: the Atlantic stock declined sharply from historical levels and has not recovered, and the causes are still debated. That decline is a material part of what an angler should know about the species.

Identification

FishingHQ holds no photograph of this species whose identity and licensing it can vouch for, so it is not showing one. Misidentified fish photographs teach identification wrongly, and a picture with an unchecked caption would be worse than none. The identification points below are what to look at instead.

Scientific name
Cynoscion regalis
Family
Sciaenidae
Water
Saltwater, Brackish
Conservation status
Endangered
Regions
North America
  • Iridescent purple, green and blue sheen on the back with gold and green flecks forming faint diagonal lines.
  • Two prominent canine teeth at the front of the upper jaw, as in spotted seatrout.
  • No distinct round black spots on the body or tail, which separates it from spotted seatrout.
  • Yellow tinge to the pelvic, anal and caudal fins, and no barbels.

Size

Typical
0.5–1.5 kg (1.1–3.3 lb)
Large
2.5–5 kg (5.5–11 lb)

Exceptional: FishBase records a maximum of 98 cm and 8.9 kg

Lifecycle and reproduction

Moderately long-lived and fast-growing, with females reaching a larger size than males. The Atlantic stock has been at low abundance for an extended period despite substantial reductions in fishing pressure, which points to causes beyond harvest alone.

Spawns in estuaries and coastal waters from spring into summer, with males drumming during courtship. Juveniles use estuaries as nursery habitat.

Feeding and senses

Takes shrimp, small fish and crustaceans in estuaries, bays and surf, feeding actively in low light and after dark. Larger fish become increasingly piscivorous, and the species follows moving water on the tide rather than holding on a fixed feature.

Hunts in turbid estuarine and coastal water using sight at close range and lateral-line detection, with sound production playing a role in spawning rather than in feeding.

Through the year

Migrates seasonally along the coast, moving inshore and northward in spring and summer and offshore and southward in autumn.

Distribution

Western Atlantic: Nova Scotia, Canada to northern Florida, USA. Introduced in Europe

This is a biological range — where the species occurs, not a prediction that you will catch one. To browse the fishing geography FishingHQ holds, start at fishing places.

Why anglers care

An Atlantic coast target taken on soft plastics, jigs, plugs and shrimp baits from shore, bay and small boat. Its significance is partly historical — it was once a far more important recreational fishery than it is now — and its decline is a live management issue. The soft mouth demands a light drag and a net rather than lifting.

Handling and returning

The mouth membrane tears easily, so never lift a weakfish by the jaw or swing it in on the line. Use a net, support the body, wet hands, and return promptly given the stock's condition.
