Weakfish

Cynoscion regalis — also called gray trout, grey trout, tiderunner (large)

The gray trout — a soft-mouthed, iridescent relative of the speckled trout found over grass flats and in the Bay's tidal creeks from spring into fall, far scarcer than it once was.

Habitat: Marshes & creeks, Chesapeake Bay
Methods: Shore, Kayak, Inshore boat
Typical size: 12–18 in
Eating: good

Identification

Look for

A dark olive back with iridescent blue-and-copper sides, a silvery-white belly, and yellow fins — the key tell versus speckled trout (Virginia's other, more commonly caught 'trout'): weakfish's dark spots are diffuse and often form diagonal lines, where speckled trout's spots are well-defined round dots that extend onto the dorsal and tail fins
Large canine teeth in the upper jaw, the same soft, easily-torn mouth ('weak' mouth) that gives the species its name and makes a light hook-set important

Typical size here: 12–18 in
Notable fish: 'Tiderunners' past 5 lb are rare today compared with past decades

Tell them apart

Look first: Check whether the spots run onto the tail and dorsal fin.

Weakfish

The diffuse diagonal rows of spots and the canine teeth do not show in this photograph's lighting; the speckled trout figure carries the spot comparison.

Speckled Trout

Look at	Weakfish	Speckled Trout
Spots	Small, diffuse spots in loose diagonal rows; none on the fins	Distinct round black spots on the back that continue onto the second dorsal fin and tail
Fins	Yellow-tinged, especially the pelvic and anal fins	Grey to dusky
Colour	Iridescent lavender, blue, and copper on the back and sides	Silvery grey with a greenish back
Mouth	Same fangs; the mouth tears easily, hence 'weak' fish	Two canine fangs in the upper jaw — both species have them

Numbers on the figures match the rows; a grey number has no mark on either figure. The canine teeth are shared and are not a tell. Weakfish are far less common in Virginia than they once were.Chesapeake Bay Program field guide — weakfish

Local waters

Chesapeake Bay tributaries, tidal creeks, and nearshore coastal waters, often over grass flats and sandy/muddy bottom

Catchable both from shore (shore) and by boat (kayak, inshore boat).

When to fish

Typically present: spring, summer, fall

Spring (April-May) through early fall (September-October) is the best window regionally.

Tide stage for this kind of water

Falling water at the creek mouths

A dropping tide drains the marsh and pulls bait out through the mouths to fish waiting below; rising water lets you paddle in.

From: Reading tides without overthinking them

Water temperature

The water, not the calendar, sets the season here — a warm October or a cold snap moves these bands.

How to catch it

Soft-plastic jigs (1/4 to 3/8 oz) worked slowly near the bottom over grass flats and along channel edges, especially at dusk.
Shrimp, bloodworm, or squid on a light two-hook bottom rig in the Bay's tidal creeks and river mouths.
Set the hook gently and keep steady pressure — the mouth tears.

Bait & lures

Live or fresh shrimp
Bloodworms or squid strips
Small live menhaden or anchovies
Soft-plastic jigs worked slowly near bottom

Tackle to start with

Ranges, not rules — match the day, the water, and the fish in front of you.

Rod: 6½–7 ft medium-light to medium spinning
Line: 10–15 lb braid
Leader: 15–20 lb fluorocarbon
Hooks: #1–2/0 for shrimp and bloodworm; 1/4–3/8 oz jig heads

On the table

Delicate, soft-textured white flesh that must be iced quickly; sauté or bake gently and eat fresh. Confirm current limits with VMRC (listed as gray trout).

Also sold and regulated in Virginia as 'grey trout' — check current regulations under that name too.
Soft mouth — light drag, no heavy hookset, and support the fish for release.

Cleaning, chilling, and cooking a legal catch covers the steps between the cooler and the pan.
