Maryland Blue Catfish Fishing 2026: Potomac, James Tributary Invasion, Limits
Maryland blue catfish in 2026—DNR tidal creel and invasive-species context, Potomac and Patuxent fisheries, and cut-bait and drift tactics in current.
2026 seasons & limits
Verify rules with Maryland fish & wildlife
- Confirm open seasons, daily bag, and possession limits for each species and water you fish.
- Check length and slot rules—many lakes, rivers, and bays have special tables beyond statewide defaults.
- Review 2026 summaries and any emergency orders (closures, health notices, gear rules) before you go.
The Inside Spread orients you for trip planning only. Conservation officers enforce the official published regulations—not articles or forum posts.
Blue catfish exploded in Potomac and Patuxent systems—trophy class on heavy tackle, invasive biology on biologists’ desks, and tidal creel tables that are not the same as Mississippi River blue rules elsewhere. DNR’s Chesapeake materials set possession and educate on invasive spread—do not move live bait or fish between waters. Pair this guide with our Maryland fishing overview for 2026.
