Bass Fishing Regulations in Maryland: What Every Angler Needs to Know
August 5, 2026
Maryland offers some of the most diverse bass fishing on the East Coast, from tidal Potomac tributaries packed with largemouth to the rocky upper reaches of the Potomac River where smallmouth thrive. Whether you’re working a topwater lure through a Chesapeake Bay tidal creek or dropping a jig into Deep Creek Lake, the rules that govern your day on the water are set by the Maryland Department of Natural Resources (DNR).
Understanding bass fishing regulations in Maryland is not optional — it is a legal requirement. Season closures, size limits, bag limits, gear restrictions, and licensing rules all apply regardless of whether you’re a lifelong resident or a visiting angler. This guide breaks down every major regulation category so you can fish confidently and legally in 2026.
Important Note: Maryland fishing regulations can change between seasons. Always verify the current rules with the Maryland DNR Fishing Regulations page before your trip, as the information here reflects sources available as of June 2026.
Bass Species Covered by Fishing Regulations in Maryland
Maryland regulates three primary bass species that anglers commonly pursue: largemouth bass, smallmouth bass, and striped bass (also called rockfish). Each species falls under its own set of rules, and the waterbody type — freshwater nontidal versus tidal — determines which regulations apply to your situation.
Largemouth bass (Micropterus nigricans) are the most widely distributed black bass in Maryland, found in reservoirs, ponds, tidal rivers, and Chesapeake Bay tributaries. Maryland DNR is in the process of updating its regulatory references to reflect the current scientific name of largemouth bass. In 2023, the American Fisheries Society revised its list of common and scientific names, changing the largemouth bass from Micropterus salmoides to Micropterus nigricans.
Smallmouth bass (Micropterus dolomieu) are concentrated in the cooler, faster-moving waters of the Potomac River, the Susquehanna River, and their tributaries. Both largemouth and smallmouth are collectively regulated as “black bass” under Maryland’s Code of Regulations (COMAR). Striped bass, while technically a different family, are included here because they represent a major bass fishery in Maryland’s tidal and coastal waters and carry their own distinct set of rules.
If you fish the Potomac River or the Chesapeake Bay, you may also encounter spotted bass and hybrid striped bass. Maryland regulations prohibit using largemouth bass, smallmouth bass, striped bass or their hybrids as live bait. Know what you’ve caught before you decide what to do with it.
Bass Fishing Season Dates and Closures in Maryland
Season rules in Maryland differ significantly between black bass (largemouth and smallmouth) and striped bass, and they also vary between freshwater and tidal waters. Knowing which category applies to your target water is the first step before you rig up.
Black Bass (Largemouth and Smallmouth) — Freshwater Nontidal Waters
Bass season in Maryland’s nontidal waters is closed from March 1 through June 15, though catch-and-release fishing is permitted at all times unless otherwise posted. During the open season, fish must be at least 12 inches, and the aggregate harvest of both species is limited to 5 fish per day. This spring closure protects bass during the spawn, when fish are most vulnerable to overharvest.
Striped Bass — Chesapeake Bay
The 2026 Chesapeake Bay striped bass recreational season runs as follows: January 1 through April 30 is catch-and-release only, with anglers required to release all fish immediately. May 1 through July 31 is the harvest season, during which anglers may keep one fish per person per day within the 19-to-24-inch slot limit.
August 1 through August 31 is a full closure — no targeting of striped bass is permitted. The harvest season resumes September 1 through December 5, with the same one-fish bag limit and 19-to-24-inch slot. December 6 through December 31 returns to catch-and-release only.
Anglers fishing the Susquehanna Flats should also note that spawning tributary protections remain in place. From March 1 through May 31, designated spawning rivers and areas are closed to all striped bass targeting, including the Susquehanna Flats and other critical spawning habitat throughout the Bay’s tributaries.
Striped Bass — Ocean Waters
The ocean recreational fishery is open year-round with a 28-inch to 31-inch slot limit and a coastwide daily bag limit of one fish. If you’re surf fishing at Ocean City or heading offshore, those are the rules governing your catch.
Pro Tip: The 2026 striped bass season restructuring is a significant change from prior years. The 2026 regulations return catch-and-release fishing in April for the first time since 2019, while moving the hot-weather closure to the entire month of August. If you fished Maryland in 2024 or 2025, review the updated calendar before heading out.
Size Limits for Bass in Maryland
Size limits are one of the most critical regulations to understand, because keeping an undersized fish carries real penalties. Maryland uses a combination of minimum length limits and slot limits depending on the species and water type.
| Species | Water Type | Size Rule |
|---|---|---|
| Largemouth Bass | Nontidal (statewide default) | 12-inch minimum |
| Smallmouth Bass | Nontidal (statewide default) | 12-inch minimum |
| Striped Bass | Chesapeake Bay (harvest season) | 19–24-inch slot limit |
| Striped Bass | Ocean / Coastal Waters | 28–31-inch slot limit |
In Maryland, largemouth bass carries a 12-inch minimum size limit, with a daily limit of 5 fish. Always check specific water body regulations, as they may vary. Some reservoirs and special management areas apply stricter slot limits that override the statewide default.
For striped bass in the Chesapeake Bay during the harvest season, the slot limit means both ends of the range are enforced. Anglers fishing the Chesapeake Bay may keep one striped bass per person per day, and the fish must fall within the 19-to-24-inch slot. Anything smaller goes back. Anything larger goes back.
Some locations in Maryland apply special size rules that differ from the statewide standard. For example, certain Montgomery County park waters use a protective slot where bass between 11 and 15 inches cannot be kept at any time of year. During open season at those waters, anglers may keep a total of five largemouth or smallmouth bass in aggregate per day, of which only one may be 15 inches or over, and bass less than 11 inches are subject to the five-per-day limit. Always check the specific rules for the waterbody you plan to fish.
Daily Bag Limits for Bass in Maryland
Maryland sets daily bag limits to prevent overharvest and keep bass populations healthy for future seasons. The limits differ by species, and in some waters, combined aggregate limits apply to both largemouth and smallmouth bass together.
Under Maryland’s Code of Regulations, an individual may not possess more than five black bass. This five-fish daily possession limit covers largemouth and smallmouth bass collectively in nontidal freshwater, meaning your total combined catch of both species cannot exceed five fish per day.
For striped bass, the daily bag limit is much more restrictive. The core harvest regulations for 2026 remain unchanged: anglers fishing the Chesapeake Bay may keep one striped bass per person per day. The same one-fish limit applies in the ocean fishery. This limit reflects the ongoing conservation measures for striped bass, which have faced recruitment challenges in recent years.
Key Insight: Possession limits in Maryland are typically double the daily bag limit. If you plan to fish multiple days and keep fish, confirm the possession limit for your target species with the Maryland DNR before storing fish from multiple trips.
Tournament anglers should also be aware of a proposed rule change from Maryland DNR. The Department is considering requiring a black bass tournament permit for all fishing tournaments with ten or more participating boats, regardless of whether they have a formal weigh-in location or offer incentives. This would include all non-possession tournaments for black bass, including catch-photo-release and catch-weigh-release events. Check the DNR’s regulations changes page for the latest status of this proposal.
Catch-and-Release Rules and Special Regulation Waters in Maryland
Catch-and-release is both a legal requirement during certain seasons and a voluntary conservation practice encouraged by Maryland DNR year-round. Understanding when you must release fish — and how to do it properly — keeps you legal and helps sustain the fishery.
During the black bass closed season (March 1 through June 15 in nontidal waters), you may still fish for bass as long as you release every fish immediately. Catch-and-release bass fishing is permitted at all times unless otherwise posted. The same principle applies to striped bass during the Chesapeake Bay catch-and-release windows in January through April and again in December.
For striped bass catch-and-release specifically, Maryland enforces gear rules designed to minimize mortality. Officials encourage anglers to practice techniques that help the fish survive, such as limiting handling and minimizing air exposure. The same gear rules that apply in March are extended through May 15 to ensure low release mortality — these rules prohibit stinger hooks, limit trolling to six rods, and require barbless hooks while trolling.
For striper release, use wet hands and knotless nets, and minimize air exposure. A dead striped bass, by law, cannot be released — it must be counted against your bag limit.
Maryland also designates special regulation waters where standard statewide rules do not apply. The state designates certain waters as catch-and-release only or with special regulations. These high-quality fisheries have stricter rules to maintain trophy populations, so always check specific water body regulations before fishing. The upper Potomac River is one well-known example, where trophy smallmouth catch-and-release rules apply in a special-regulations zone. For a full list of special management areas, visit the eRegulations Maryland freshwater seasons page.
If you fish bass in other states along the Mid-Atlantic, it helps to compare regulations side by side. Rules in neighboring states like Virginia and North Carolina differ from Maryland’s, so never assume one state’s rules carry over.
Legal Gear and Bait Restrictions for Bass in Maryland
Maryland’s gear rules for bass vary between freshwater and tidal waters, and some restrictions are species-specific. Fishing with illegal gear — even unintentionally — can result in fines and the loss of your fishing privileges.
Tidal Waters (Chesapeake Bay and Tributaries)
An individual may not catch black bass in any manner in the tidal waters of the state except with rod or hook and line using natural or artificial baits. Any black bass caught in a net, seine, or other device while engaged in other fishing must be immediately returned unharmed to the water.
For striped bass in tidal waters, additional gear rules apply. Circle hooks are required when bait fishing for striped bass in the Chesapeake Bay. A maximum of two hooks or two baited rigs are permitted when targeting striped bass. No gaffing of striped bass is allowed — nets only. Chumming for striped bass is prohibited in restricted zones.
General Statewide Restrictions
- No snagging of game fish is permitted under any circumstances.
- You may not use largemouth bass, smallmouth bass, striped bass, or their hybrids as live bait.
- An individual may not sell, offer to buy or sell, expose for sale, or purchase any black bass at any time.
- Striped bass may not be cut or filleted aboard any boat on tidal waters. Striped bass must be landed whole.
- Sabiki rigs and mackerel trees are prohibited in Maryland state waters, though they are allowed in the Exclusive Economic Zone of the Atlantic Ocean.
Pro Tip: Gear rules for striped bass in the Chesapeake Bay are updated more frequently than freshwater bass rules. Annual regulations change — check the DNR Fishing Guide every spring to confirm hook rules, trolling limits, and any new restrictions before your first trip of the season.
Bass Fishing License Requirements in Maryland
Maryland divides its fishing license structure into two categories based on water type, and many bass anglers need to understand both. The type of water you fish — not just the species you target — determines which license you must carry.
Maryland’s angling regulations divide waters into two main categories: nontidal (freshwater) and tidal (Chesapeake Bay, coastal, and their tributaries), and the license type you need depends entirely on where you fish.
Freshwater (Nontidal) Bass Fishing
If you fish largemouth or smallmouth bass in Maryland’s rivers, lakes, reservoirs, or streams above the tidal influence line, you need a Nontidal Sport Fishing License. Maryland DNR updated its nontidal fishing license fees in 2025 — the first increase in nearly 20 years — and those new rates carry into 2026. A resident annual nontidal license now costs $32, and a Chesapeake Bay & Coastal license is $15 annually.
Tidal Bass Fishing (Striped Bass / Bay Waters)
Anglers targeting striped bass in the Chesapeake Bay, its tidal tributaries, or the Atlantic coastal waters need a Chesapeake Bay & Coastal Sport Fishing License. Tidal licenses cover the Chesapeake Bay and all its tidal tributaries, plus the Atlantic coastal waters. Tidal license fees were not changed in the 2025 restructuring and remain at their prior levels for 2026.
| License Type | Resident Annual | Resident 7-Day |
|---|---|---|
| Nontidal (Freshwater) Sport Fishing | $32.00 | $16.00 |
| Chesapeake Bay & Coastal Sport Fishing | $15.00 | $6.00 |
Source: eRegulations Maryland Fishing Licenses & Fees, last updated January 27, 2026. Non-resident fees are higher and based on a reciprocal rate structure — check the Maryland DNR for your state’s applicable fee.
Who Does Not Need a License
Every angler aged 16 or older must carry a valid license to fish, unless they qualify for an exemption. Key exemptions include:
- Anglers under 16 years of age — no license required for any fishing type
- Maryland residents who are 100% service-connected disabled veterans, former prisoners of war, and veterans deemed unemployable by the VA receive complimentary fishing licenses.
- Property owners or tenants, their spouse, child, or the spouse of their child residing on the property may fish without a license from the property’s riparian shoreline in nontidal waters.
- Maryland residents on active military duty with official leave orders
Free Fishing Days
In Maryland, anyone may fish without a recreational fishing license on June 6, June 13, and July 4, 2026. All other fishing regulations apply. Size limits, bag limits, season rules, and gear restrictions remain fully in force on free fishing days — only the license requirement is waived.
All Maryland fishing licenses are valid for 365 days from the date of purchase, not by calendar year. A license bought in August 2026 is good through August 2027.
You can purchase your Maryland fishing license online through the MD Outdoors portal, at any DNR Service Center, or at licensed retail agents including sporting goods stores and tackle shops. A fishing license is required to fish for striped bass. Maryland anglers can purchase their licenses online at MD Outdoors, at DNR service centers, or at sport license agent retailers.
Regulations in neighboring states can differ substantially. If you also fish in Pennsylvania or plan a trip to states like Tennessee, Georgia, or Florida, make sure you review each state’s rules independently.
Where to Find Current Bass Regulations in Maryland
Maryland’s bass regulations — particularly for striped bass — can shift from one season to the next. Relying on last year’s rules or secondhand information is a common mistake that can lead to unintentional violations. Always go to an authoritative source before you fish.
Here are the most reliable places to check current Maryland bass fishing regulations:
- Maryland DNR Fishing Regulations page — dnr.maryland.gov/fisheries/pages/regulations — The official state source for all current rules, including season calendars, size and bag limits, and special management area maps.
- Maryland DNR Regulations Changes page — dnr.maryland.gov/fisheries/pages/regulations/changes.aspx — Lists proposed and recently adopted rule changes, including pending decisions like the black bass tournament permit requirement.
- eRegulations Maryland Fishing Guide — eregulations.com/maryland/fishing — A well-organized digital version of the official Maryland Guide to Fishing and Crabbing, updated each season.
- Code of Maryland Regulations (COMAR) — The legal text of all fishing regulations is searchable at the Maryland Library of Regulations for anglers who want to read the exact statutory language.
- MD Outdoors app and portal — Available through the Maryland DNR, this is where you purchase licenses and can access regulation summaries digitally in the field.
Regulations may have changed — always verify with the official agency before your trip, especially for striped bass, where seasonal windows and gear rules are subject to annual review. Recreational fishing and boating generate an estimated $701.5 million in value-added economic activity in Maryland, as of 2024, according to outdoor recreation statistics compiled by the federal Bureau of Economic Analysis — a figure that reflects just how seriously Maryland takes the health of its fisheries.
If you’re planning a multi-state bass fishing trip, it’s worth reviewing regulations in other states you’ll visit. Rules for bass fishing in Ohio, Michigan, and Wisconsin all differ from Maryland’s framework, so check each state separately. For anglers closer to home, the Maryland bass fishing season guide offers additional detail on timing and location strategies across the state.
