Regulations by jurisdiction
Maryland (tidal)

Invasive species in Maryland tidal waters. No minimum size, no creel limit, open year-round. MDDNR encourages anglers to harvest rather than release. Not listed in the Chesapeake Bay seasons/sizes/limits table because no restrictions apply.

Virginia (tidal — VMRC)
tidal bay
- Creel
- 20
Virginia tidal rivers (James, York, Rappahannock, and their tributaries below the fall line) and inland Lake Gaston / Kerr Reservoir: effectively unlimited harvest of fish under 32 inches, BUT only 1 fish per day over 32 inches (trophy-size retention cap to preserve the big-fish fishery despite the invasive status). The general freshwater creel (20/day) applies above the fall line. VA has been actively reconsidering the 32-inch cap — a 2025 bill proposed removing it — so re-verify before relying on this for a trophy-size retention claim.
