What You'll Find in the Preserve

The Pascagoula River Marsh Coastal Preserve is a 28,000-acre protected area where the river meets the Gulf, mixing freshwater marsh, brackish creeks, and open water in a way that holds redfish, spotted seatrout, and flounder year-round. The preserve runs from the river's mouth near Pascagoula south through the barrier islands and includes shallow bays, tidal flats, and the intricate marsh channels that make the system work. Unlike the developed shoreline to the west, this area has stayed mostly wild because it's owned and managed by The Nature Conservancy, which allows fishing under specific rules.

The water here is shallow—most of it runs two to four feet deep—and the bottom shifts between sand, mud, and oyster shell depending on how far you are from the Gulf. Salinity changes with the tide and season; the upper marsh near the river mouth runs nearly fresh in spring, while the lower bays stay brackish year-round. That variation is what makes it work for both warm-water species and the occasional tarpon or permit that wanders in from deeper water.

Key Takeaways

  • The preserve allows fishing from boats and on foot, but you cannot use motors in designated sanctuary zones—check the current zoning map before you go.
  • Redfish and spotted seatrout are the main target species, with best fishing in the marsh channels and shallow bays during incoming tide.
  • Access is by boat only; there are no public boat ramps inside the preserve, so you'll launch from Pascagoula or nearby marinas and run in.
  • The preserve is closed to hunting and has strict rules on bait collection, so bring your tackle from home rather than netting shrimp on-site.

How to Access the Preserve by Water

You reach the preserve by boat from Pascagoula's public ramps or from private marinas along the river. The closest public launch is at Pascagoula Riverfront Park, which has a concrete ramp and parking; from there, you run south down the river channel for about 15 minutes to reach the lower marsh and the preserve boundary. The river is well-marked and dredged to six feet or more, so navigation is straightforward until you leave the main channel and head into the shallower bays.

Once you're in the preserve, stay alert for shallow water and oyster bars, especially on low tide. A shallow-draft skiff or poling skiff works best; anything drawing more than two feet will limit where you can go. If you're running a larger boat, stick to the main channels and the deeper bays near the barrier islands. GPS and a good tide table are essential—the tidal range here is about two feet, and being caught on a bar at low tide means a long wait or a tow.

Fishing Seasons and Target Species

Redfish are present year-round in the marsh channels and shallow bays, with the best fishing from April through October when they're feeding actively in the shallows. Spotted seatrout show up in numbers from May through September, especially in the deeper bays and along the edges of the marsh. Both species respond to incoming tide, when water pushes into the marsh and baitfish move with it. Early morning and the last two hours of daylight are most productive.

Flounder live on the sandy bottom in the deeper bays and the channels leading to the Gulf; they're catchable year-round but most abundant in fall and spring. Tarpon and permit are rare visitors, usually showing up in summer when Gulf water pushes far into the bays, but it happens often enough that sight-casting for them is worth trying if you see tailing fish. Mullet, ladyfish, and catfish round out the catch, though most anglers focus on redfish and trout.

Tackle and Bait for Marsh Fishing

Light to medium spinning tackle works for everything in the preserve. A 6.5- to 7-foot rod with 15- to 20-pound braid handles redfish and trout without being overkill, and it's sensitive enough to feel the bottom and detect strikes. Bring a mix of lures: topwater plugs for early morning and late evening, soft plastics in natural colors (pearl, chartreuse, and mullet patterns) for sight-casting, and small spoons for deeper water and faster current.

Live bait—mullet, menhaden, or shrimp—works well if you bring it from outside the preserve. You cannot net bait inside the preserve boundaries, so plan ahead. If you're using artificials, focus on areas where the marsh edge meets open water, where the current breaks, and along the deeper channels. The water is often clear enough to sight-cast, especially on calm days and high tide, so polarized sunglasses and a good pair of eyes are as important as the rod.

Rules and Restrictions in the Preserve

The Nature Conservancy manages the preserve and allows fishing, but with conditions. Motorized boats are banned in designated sanctuary zones—currently the upper marsh and some of the smaller creeks—so check the zoning map before you launch. Most of the main bays and channels allow motors, but speed limits apply in shallow areas. Hunting is not allowed anywhere in the preserve, and collecting bait by netting or trapping is prohibited.

You need a valid Mississippi fishing license to fish here, and state bag limits apply: five redfish per day (with slot restrictions), 15 spotted seatrout per day, and five flounder per day. Tarpon and permit are catch-and-release only. Camping and overnight stays are not permitted. The preserve is open year-round, but weather and water conditions can make access difficult in winter, and summer heat and mosquitoes can be intense—early morning and late evening trips are more comfortable.

When to Fish and What to Expect

Spring (March through May) brings rising water and active feeding as fish move into the shallows. Water is warming, and the marsh is greening up; this is prime time for redfish on topwater and trout in the bays. Summer (June through August) is hot and humid, but fishing can be excellent early and late in the day. The water is warm and clear, and sight-casting opportunities are best. Afternoon thunderstorms are common, so plan to be off the water by mid-afternoon.

Fall (September through November) cools the water and brings another feeding push. Redfish and trout are aggressive, and the weather is more comfortable for all-day trips. Winter (December through February) is mild by northern standards, but water temperatures drop into the 50s, and fish move deeper into the channels and bays. Fishing is slower but still possible, and the preserve is less crowded. Wind can be a problem any time of year, especially in winter and spring, so check the forecast before you commit to a trip.

Planning Your Visit

Bring plenty of water, sunscreen, and insect repellent—the mosquitoes are serious in warm months. A tide table or a tide app on your phone is essential; plan your fishing around incoming tide and the last two hours of daylight. If you're unfamiliar with the area, consider hiring a guide for your first trip; local guides know the channels, the seasonal patterns, and the best spots for each species. Pascagoula has several guide services that fish the preserve regularly.

Gas up before you launch; there are no fuel docks inside the preserve. Bring a kill switch and a working VHF radio if you have one. The preserve is remote enough that cell service is spotty, so let someone know where you're going and when you expect to return. Weather can change quickly, and the shallow water means you're never far from a bar or a shallow spot, so respect the water and don't push your luck if conditions deteriorate.

Frequently Asked Questions

Do I need a permit to fish the Pascagoula River Marsh Coastal Preserve?

No permit is required beyond a valid Mississippi fishing license. The preserve is open to the public for fishing under state regulations and The Nature Conservancy's management rules. You do need to follow the zoning restrictions—no motors in sanctuary zones—so check the current map before you launch.

Can I wade fish in the preserve?

Yes, wading is allowed in the shallower areas, though most anglers fish from boats because the preserve is large and the best water is often a run away from the nearest shore. If you do wade, wear a life jacket, watch for deep holes and oyster bars, and stay aware of the tide—incoming tide can cut off your exit quickly in some areas.

What's the best time of year to fish here?

Spring and fall offer the most comfortable weather and active fish. April through May and September through November are peak seasons. Summer fishing is good early and late in the day, but heat and afternoon storms limit all-day trips. Winter is slower but less crowded and still productive if you fish the deeper channels.

Are there fish here year-round?

Yes. Redfish and flounder stay in the preserve all year. Spotted seatrout are most abundant May through September but are present other months too. Tarpon and permit are rare and mostly a summer possibility. You can catch fish in any season, but spring and fall are most reliable.

What should I do if I get stuck on a bar at low tide?

Stay calm and wait for the tide to rise—it typically takes two to three hours. If you're in a shallow-draft boat, you may be able to pole off. If you need help, call the Coast Guard on VHF Channel 16 or use your cell phone if you have service. Carry a spare anchor and line in case you need to hold position, and always tell someone on shore where you're going.
