Weakfish
A finesse fish defined by fragility as much as beauty, weakfish run the Atlantic coast of North America from Nova Scotia down to northern Florida, with the heart of their range between the mid-Atlantic and the Carolinas.
Their paper-thin mouths — the source of the name — demand a soft touch and a forgiving rod, and their populations swing dramatically from year to year, making a strong weakfish season feel like something worth chasing.
Scientific Name: Cynoscion regalis
Also known as Gray trout, Sea trout, Squeteague, Gray sea trout
- Olive-green back fading to silvery sides washed with iridescent purple, lavender, copper, and gold — one of the more colorful fish in the inshore Atlantic.
- Sides are flecked with dark blotches that form wavy, diagonal lines running down and forward; yellow fins are a reliable field mark.
- Two prominent canine-like teeth in the upper jaw distinguish it from most other inshore species at a glance.
- Separated from spotted seatrout by the absence of spots on the tail and second dorsal fin. Most fish run 12–16 inches; large 'tiderunners' can push 10+ pounds and 36 inches.
What to know
Habitat Distribution
- Native to the western Atlantic from Nova Scotia to northern Florida, with the densest populations concentrated between the mid-Atlantic coast and the Carolinas.
- A coastal and estuarine species — adults push inshore and northward as water warms in spring and summer, using surf zones, inlets, bays, and tidal channels before retreating offshore and south in autumn.
- Juveniles rely on estuaries as nursery habitat; adults range from shallow back bays to nearshore coastal waters depending on season.
Specific Spots
- Large tiderunners in spring stack in the deeper channels of back bays, particularly at confluence points where two channels meet and tidal current concentrates bait.
- Eelgrass edges and sandy drop-offs hold fish that are working the transition between cover and open bottom — the outside edge of a grass flat is worth a slow drift.
- Bridge pilings, dock lights, and lit abutments draw fish after dark in summer, when low-light conditions and current breaks put bait in predictable lanes.
Weakfish FAQ
Answers from onWater's species guide.
What are the best lures and bait for Weakfish?
Small bucktails in white, yellow, pink, or chartreuse, tipped with a soft plastic tail or pork rind, are the go-to across the range. The combination mimics shrimp or small baitfish and gives the jig a more lifelike action on the fall.
What do Weakfish eat?
Juveniles and smaller fish key on shrimp, crabs, and small clams; as fish grow, the diet shifts toward baitfish, anchovies, menhaden (bunker), Atlantic silversides (spearing), butterfish, and herring. Match the forage with small bucktails, swim shads, or natural baits like grass shrimp and peanut bunker.
Where do Weakfish live?
