Southern Flounder

Paralichthys lethostigma

The lower-salinity cousin of summer flounder — an occasional lower-Bay and tidal-creek catch without the summer flounder's ringed spots, more at home well upriver.

Identification

Look for

  1. Lacks the summer flounder's bold, eye-like (ocellated) spots — southern flounder shows only indistinct, diffuse spotting on a brownish upper body
  2. Fewer gill rakers on the lowermost gill arch (9-10) than summer flounder (15 or more) — a count only relevant if examining a specimen closely, not a glance-level field mark
  3. Both eyes on the left side of the head, same as summer flounder — this alone does not distinguish the two species

Tell them apart

Look first: Ringed spots mean summer flounder; diffuse blotches mean southern.

Numbers on the figures match the rows; a grey number has no mark on either figure. Summer flounder is by far the more common of the two in Hampton Roads; southern flounder is an occasional lower-Bay catch.NOAA Fisheries — summer flounder

Local waters

  • Brackish tidal rivers and creeks
  • Marsh edges
  • More tolerant of low salinity than summer flounder, so found further upriver

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

When to fish

Typically present: summer

Warmer months, in brackish tidal rivers and creeks — a genuinely distinct species from the far more commonly encountered summer flounder, documented as an occasional visitor to the lower Chesapeake Bay rather than a routine catch.

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.

Water temperature and the seasons

How to catch it

  • Fished exactly like summer flounder — a minnow or strip bait dragged slowly with the current — but well up the tidal creeks and rivers where salinity drops.
  • Give the fish a moment before lifting; both flounders grab the tail of a bait first.

Bait & lures

  • Live mud minnows or finger mullet on a Carolina rig
  • Bucktail tipped with Gulp! or a minnow

On the table

Indistinguishable from summer flounder on the plate — mild, lean, fine-flaked. Confirm current limits with VMRC.

  • Documented as an occasional visitor to the lower Chesapeake Bay, Virginia — its core U.S. range runs Virginia to Texas, with North Carolina and points south the more consistent fishery. This project has not found a Virginia-specific southern flounder regulation distinct from summer flounder's own current size/possession rules — check VMRC's current saltwater regulations directly before harvesting, and do not assume the two species share identical limits without confirming.

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

Where to try

Water that suits southern flounder

Spots marked “habitat match” share this species' water type, habitat, and methods — not a report that it has been caught there.
