Saltwater · Year-round in northern Gulf bays; best in spring and fall
Sand Seatrout
Cynoscion arenarius
The northern Gulf's plain, unspotted seatrout. In low-salinity northern Gulf bays it largely replaces the spotted seatrout. Abundant, willing and good on light tackle, it is a staple bay fish — but its soft flesh must be eaten fresh.

Identifying features
- No spots at all on body or fins — the key split from spotted seatrout
- Pale silvery-gray to faintly golden color
- Elongate soft-rayed body with a slightly upturned, protruding lower jaw
- Prominent canine teeth at the front of the upper jaw
- Soft flesh and easily torn mouth — fish feel light for their size
Habits
- Schools over sand and shell bottoms in bays and passes
- In the northern Gulf it replaces spotted seatrout in low-salinity bays
- Feeds mainly on shrimp and small fish, often at night around lights
- Spawns in bays and passes through spring and summer
- Meat softens quickly after death — ice immediately and eat fresh
Distribution
Where to find them
- Bay shell and sand flats off the Florida Panhandle
- Louisiana bay channels and passes
- Texas bay bridges and lighted piers at night
Where they live
How to catch them
Shrimp or soft plastics under popping corks Boat
Rig: Popping cork rig with shrimp or a soft plastic jig suspended 2-4 ft below, worked over bay shell and sand bottoms
Bait/lure: Shrimp, soft plastic jigs
Key tip: Pop the cork sharply and let it sit — sand trout rise to the sound and take the bait on the pause.
Bottom fishing with cut bait at night Shore
Rig: Simple bottom rig with small pieces of cut bait or dead shrimp, fished around bridges and lighted piers after dark
Bait/lure: Cut bait, dead shrimp
Key tip: Use a gentle lift on the strike — their mouths tear easily, so play fish softly on light drag.
