What Atlantic Sturgeon Are and Where They Live

Atlantic sturgeon are large, long-lived fish that spend most of their lives in the ocean but return to freshwater rivers to spawn. They are prehistoric-looking fish with bony plates running along their sides instead of scales, and they can live 50 years or longer. A mature Atlantic sturgeon can weigh 200 pounds or more, though most fish you encounter will be smaller.

These fish live along the Atlantic coast from Canada to Florida, but they spawn in specific river systems. The major spawning rivers include the Hudson River in New York, the Delaware River between Pennsylvania and New Jersey, the Potomac River in Maryland and Virginia, and several rivers in the Carolinas. Sturgeon spend their non-spawning years in coastal bays and ocean waters, moving into rivers only when water temperatures and other conditions trigger the spawning run.

Atlantic sturgeon are a protected species under federal law. Their populations crashed in the early 1900s due to overfishing for caviar and meat, and they have never fully recovered. This protection shapes everything about where and how you can fish for them.

Key Takeaways

  • Atlantic sturgeon are protected under the Endangered Species Act, and fishing for them is prohibited in most places; some rivers allow catch-and-release only under specific conditions.
  • The Hudson River in New York and the Delaware River permit limited catch-and-release fishing during spawning season, but you must follow strict regulations including hook type and handling requirements.
  • Sturgeon season runs roughly from April through June in most rivers, timed to the spawning run when fish move upstream from coastal waters.
  • If you hook a sturgeon, you must immediately release it and report the catch to the state fisheries agency within 24 hours in most jurisdictions.
  • Check your state's current regulations before planning a trip, because rules change year to year and vary significantly between river systems.

Federal Protection and What It Means for Fishing

Atlantic sturgeon are listed as endangered under the federal Endangered Species Act. This means that in most waters, you cannot keep a sturgeon under any circumstances. Fishing for them is prohibited entirely in many river systems, and in others it is restricted to catch-and-release only during specific windows.

The U.S. Fish and Wildlife Service and NOAA Fisheries set the federal rules, but individual states manage the day-to-day regulations on their rivers. This creates a patchwork: the Hudson River in New York allows limited catch-and-release fishing, the Delaware River permits it under a special permit system, and the Potomac River prohibits it entirely. Before you plan a trip, you must check both the federal rules and your state's current regulations, because they change and sometimes close fishing temporarily.

If you do hook a sturgeon, federal law requires you to release it immediately and report the catch. Most states require this report within 24 hours. Failing to report is a violation, even if you released the fish unharmed. The reporting requirement exists so fisheries managers can track population recovery.

The Hudson River: New York's Catch-and-Release Fishery

The Hudson River is one of the few places where you can legally fish for Atlantic sturgeon. New York's Department of Environmental Conservation allows catch-and-release fishing during the spawning season, which typically runs from mid-April through mid-June, though exact dates shift slightly each year.

To fish for sturgeon on the Hudson, you need a New York fishing license and must follow strict gear requirements. You must use a single hook (no treble hooks), and the hook must be barbless or have the barb flattened. Circle hooks are preferred because they reduce injury to the fish. You cannot use live bait; only dead bait or artificial lures are permitted. The goal of these restrictions is to maximize the chance that a hooked sturgeon survives release.

Sturgeon in the Hudson are found in deeper channels and holes, particularly around the Tappan Zee area and further upriver toward Troy. Spring water temperatures and river flow trigger the spawning run, so fishing is best when water temperatures are between 50 and 65 degrees Fahrenheit. You must report any sturgeon you catch to New York DEC within 24 hours by phone or online.

The Delaware River: Permit-Based Catch-and-Release

The Delaware River, which forms the border between Pennsylvania and New Jersey, also permits catch-and-release sturgeon fishing, but access is more tightly controlled. Both states issue a limited number of special permits each year, and the permit process is competitive. Permits are typically issued through a lottery system, and demand far exceeds supply.

If you obtain a permit, the season usually runs from April through June, with specific dates announced each year. Like the Hudson, you must use single barbless or circle hooks and cannot use live bait. The Delaware River's sturgeon population is smaller than the Hudson's, so sightings and catches are less frequent, but the fish that do spawn here are part of a distinct population that fisheries managers monitor closely.

Both Pennsylvania and New Jersey require catch reporting within 24 hours. Contact the Pennsylvania Fish and Boat Commission or the New Jersey Division of Fish and Wildlife for current permit availability and application deadlines, as these change annually.

Other Rivers and Closed Waters

Most other Atlantic coast rivers do not permit sturgeon fishing at all. The Potomac River, which is historically important for Atlantic sturgeon, is closed to all sturgeon fishing. The same is true for rivers in the Carolinas, despite their significance for spawning. These closures reflect the fragile status of sturgeon populations in those systems.

Coastal bays and ocean waters are also closed to sturgeon fishing. Even if you encounter a sturgeon in a bay or estuary, you cannot target it or keep it. The only legal fishing opportunity is in the Hudson and Delaware rivers during their respective seasons, under the conditions described above.

If you fish in any Atlantic coast river during spring and accidentally hook a sturgeon, you must release it immediately and report the catch, even in closed waters. This reporting helps managers understand where sturgeon are moving and how populations are changing.

Seasons, Water Conditions, and Timing

Atlantic sturgeon spawning runs occur in spring, typically from April through June, though the exact timing depends on water temperature and flow. Sturgeon are triggered to move upstream when water temperatures reach the 50 to 65 degree Fahrenheit range. In years with early warm springs, the run may start in late March; in cold years, it may not peak until late May or early June.

River flow also matters. High water from spring snowmelt or heavy rain can push sturgeon upstream faster and make them more active. Low water can slow the run and concentrate fish in deeper pools. Local fishing reports and state fisheries agencies post updates on run timing and conditions, so check before you go.

Sturgeon are bottom feeders and prefer deep holes and channels. On the Hudson, fish congregate in areas with strong current and depth. Early morning and late evening are often productive, though sturgeon can feed throughout the day. Patience is essential; sturgeon fishing is not fast-paced, and you may spend hours without a bite.

Gear, Bait, and Technique

For Hudson River sturgeon, use a medium to heavy rod with a sensitive tip so you can feel the subtle bite of a sturgeon. A conventional reel or spinning reel works, but you need enough line capacity for a large fish and enough drag to handle a 100-pound-plus sturgeon if one takes your bait. Braided line is popular because it provides better sensitivity and strength.

Dead bait is the standard approach. Shad, herring, and mackerel are effective, fished on the bottom in deep holes. Use a three-way rig or a simple slip sinker setup that keeps your bait on or near the bottom. Circle hooks in sizes 4/0 to 8/0 work well and are required to be barbless or have the barb flattened. Cast near structure, deep channels, and current breaks, then wait for a sturgeon to find your bait.

When a sturgeon takes your bait, you will feel a steady pull rather than a sharp strike. Set the hook with a firm, steady motion, not a violent jerk. Once hooked, keep steady pressure and let the fish run if it wants to. Sturgeon are powerful but not acrobatic; they dive and pull hard rather than jumping. Play the fish to exhaustion so it can be safely landed, handled briefly for reporting purposes, and released.

Regulations, Reporting, and Conservation

Every state and the federal government require that any Atlantic sturgeon you catch be reported within 24 hours. On the Hudson, you can report online through the New York DEC website or by phone. On the Delaware, contact the Pennsylvania Fish and Boat Commission or New Jersey Division of Fish and Wildlife. Have the date, time, location, and approximate size of the fish ready when you report.

Regulations change year to year based on population monitoring and management decisions. Some years, catch-and-release fishing may be closed temporarily if monitoring shows a population decline. Always check your state's current regulations before planning a trip. Regulations are posted on state fisheries agency websites and are updated annually.

Conservation is the reason these restrictions exist. Atlantic sturgeon populations remain far below historical levels, and every fish that survives to spawn contributes to recovery. By following hook requirements, handling fish carefully, and reporting catches, anglers help managers understand population trends and support long-term recovery efforts.

Frequently Asked Questions

Can I keep an Atlantic sturgeon if I catch one?

No. Atlantic sturgeon are protected under the Endangered Species Act, and keeping one is illegal everywhere. You must release any sturgeon you hook immediately and report the catch to your state fisheries agency within 24 hours.

What if I accidentally hook a sturgeon while fishing for something else?

Release it immediately and report the catch within 24 hours, even if you were not targeting sturgeon. The report helps managers track where sturgeon are moving and how populations are changing. Provide the date, time, location, and approximate size.

Do I need a special permit to fish for sturgeon on the Hudson River?

No. A regular New York fishing license is sufficient for Hudson River catch-and-release sturgeon fishing during the open season. The Delaware River does require a special permit, which is issued through a lottery system with limited availability.

What time of year is best for sturgeon fishing?

April through June is the spawning season when sturgeon move into rivers from coastal waters. Peak fishing is usually mid-April through mid-May, depending on water temperature and flow. Check state reports for current run timing before you go.

Why are Atlantic sturgeon so heavily protected?

Atlantic sturgeon populations crashed in the early 1900s due to overfishing for caviar and meat. They have never recovered to historical levels. Protection under the Endangered Species Act aims to allow populations to rebuild so the species can eventually be removed from the endangered list.
