What the Little Biloxi River offers and where to find it
The Little Biloxi River is a short, narrow estuary that branches off the main Biloxi River system just east of Ocean Springs, running roughly three miles before it opens into the Mississippi Sound. It's shallow throughout—most of it runs two to four feet deep—and lined with marsh grass, mangrove edges, and oyster bars that make it feel more like a bayou than a river. The water is brackish, mixing fresh flow from inland with salt tidal influence, which creates the conditions redfish and spotted seatrout prefer.
Access is limited compared to the main Biloxi. There's a public boat launch at the Ocean Springs Harbor on the main river, and from there you run east into the Little Biloxi's mouth. The river itself has no public ramps, so you're launching from the main system and running in. The narrow channel means you'll see fewer boats than the broader waters, and the shallow flats and grass edges hold fish year-round, though fall and spring are the most consistent seasons.
Key Takeaways
- The Little Biloxi is a shallow, narrow estuary best fished by boat from the Ocean Springs Harbor launch, running three miles into the Mississippi Sound with depths of two to four feet throughout.
- Redfish and spotted seatrout are the primary target species, with redfish favoring the marsh edges and seatrout holding on the deeper flats and oyster bars.
- Tidal movement is critical—fish feed most actively on the incoming tide when water pushes into the shallow grass and marsh, concentrating baitfish and triggering strikes.
- Sight-casting to tailing redfish in the shallows is the most effective technique, though blind casting along grass edges and oyster bars works when fish aren't visible.
- Summer heat and low water clarity can make fishing difficult; fall through spring offers clearer water and more predictable feeding patterns.
Tidal patterns and when fish feed
Tidal swing in the Little Biloxi is modest—usually two to three feet—but it controls where and when fish will eat. The incoming tide pushes water into the shallow marsh and grass flats, concentrating mullet, silversides, and small crustaceans that redfish and trout hunt. Fish move shallow on the incoming tide and retreat to slightly deeper water on the outgoing tide, so plan your fishing around the tide calendar rather than the clock.
The best window is typically the last two hours of incoming tide and the first hour after high tide turns. During this period, redfish will cruise the grass edges and marsh perimeter, and seatrout will hold on the flats where baitfish are concentrated. Low tide can be productive too, but only in the deeper pockets and channels where fish hold tight. Slack tide—the brief period between incoming and outgoing—is often the slowest time, so use it to reposition or scout new water.
Redfish in the shallows and marsh edges
Redfish are the signature fish of the Little Biloxi, and they're catchable year-round in water so shallow you can see their backs. They hunt the grass edges and marsh perimeter, especially where the marsh transitions to open water. On a rising tide, they'll push into the grass itself, tailing as they root for crabs and shrimp. This is sight-casting water—you're looking for the telltale swirl or the tail breaking the surface, then casting ahead of the fish and stripping a fly or working a soft plastic slowly back.
Redfish in this system run eight to twenty pounds on average, with occasional fish pushing into the mid-twenties. They're not aggressive—the shallow water and clear conditions mean they see your presentation clearly, so accuracy and a natural retrieve matter more than speed. A six to eight-weight fly rod with a floating line works well, as does a medium-light spinning rod with a quarter-ounce soft plastic on a jighead. Cast ahead of the fish, let it settle, and strip or twitch it slowly. If the fish doesn't respond on the first cast, move on—a spooked redfish won't eat.
Spotted seatrout on the deeper flats and bars
Spotted seatrout prefer slightly deeper water than redfish—they'll hold on the three to four-foot flats and around the oyster bars scattered throughout the system. They're more aggressive than redfish and will chase a moving bait or lure, making them easier to catch but less predictable in location. Look for them on the edges of the deeper channels and around any structure—oyster bars, submerged logs, or the transition zones between grass and open water.
Seatrout respond well to small topwater plugs, soft plastics in the two to three-inch range, and shrimp patterns on a fly rod. Cast and retrieve steadily rather than sight-casting; you're covering water and triggering strikes rather than targeting individual fish. The incoming tide concentrates them, but they'll feed throughout the tidal cycle if the water is clear. Fish the deeper flats on the outgoing tide when redfish have retreated, and you'll often find seatrout holding in the same water.
Tackle and fly patterns for the Little Biloxi
A six to eight-weight fly rod with a floating line and a nine-foot leader tapered to 12-pound tippet covers most situations. Bring a few patterns: a tan or olive Clouser Minnow in size 2 or 3 for redfish, a small shrimp pattern like a Permit Fly or simple chenille shrimp for both species, and a small crab pattern for the marsh edges. Redfish will eat a crab, and seatrout will chase a minnow, so having options matters less than having a few patterns you can cast accurately.
For spinning, a medium-light rod with 15-pound braided line and a fluorocarbon leader handles the shallow water and occasional larger fish. Soft plastics in natural colors—tan, white, chartreuse, and pearl—work better than bright patterns in the clear water. A quarter-ounce jighead keeps the bait in the strike zone without sinking too fast, and a slow, steady retrieve is more effective than aggressive jerking. Topwater plugs in the two to three-inch range work on the incoming tide when fish are feeding actively.
Seasonal patterns and water conditions
Fall and spring offer the clearest water and most consistent fishing. Water temperatures in the 65 to 75-degree range trigger active feeding, and the moderate tides mean fish aren't pushed into the deepest refuges. Summer heat can muddy the water and push fish into the deeper channels and sound, making sight-casting difficult. Winter is fishable but slower; redfish and seatrout are still present, but they're less aggressive and hold tighter to structure.
Water clarity is the limiting factor. After heavy rain or strong wind, the Little Biloxi can turn brown, and sight-casting becomes impossible. During these periods, focus on the deeper flats and channels where fish hold regardless of visibility, and use darker fly patterns or louder topwater plugs that fish can locate by sound and vibration. Clear, calm days are ideal—you can see fish from fifty feet away and make precise casts that trigger strikes.
Navigation and safety on a narrow river
The Little Biloxi is narrow enough that you need to watch for shallow spots and deadfall. The main channel is marked, but it's easy to run aground on the flats if you're not paying attention. Use a shallow-draft boat—a skiff, flats boat, or even a kayak works well here. Pole or drift rather than running at speed; you'll spook fish and risk hitting submerged obstacles. A push pole or trolling motor gives you control and lets you approach fish quietly.
The river opens into the sound, and conditions can change quickly. Check the forecast before you go, and stay aware of wind direction and tide. A rising tide combined with strong wind can push water out of the river faster than expected, leaving you in very shallow water. Conversely, a falling tide with wind pushing from the sound can raise water levels. Carry a GPS or know the channel markers; it's easy to get turned around in the marsh, especially on overcast days.
Frequently Asked Questions
Can I fish the Little Biloxi from a kayak?
Yes, and it's an excellent kayak fishery. The shallow water and narrow channel are ideal for a kayak's draft, and you can access areas a motorboat can't reach. Bring a push pole or anchor to hold position on the flats, and be aware that tidal current can move you quickly in the narrow sections. Wear a life jacket and stay aware of boat traffic near the main river mouth.
What's the best time of day to fish?
Tidal timing matters more than time of day. Fish feed most actively on the incoming tide regardless of whether it's morning or afternoon. That said, early morning offers calmer water and better visibility, which makes sight-casting easier. Evening can be productive too, especially if the incoming tide coincides with the last hour of daylight.
Do I need a guide to fish the Little Biloxi?
No, but a guide can accelerate your learning curve. The river is small enough to explore on your own, and the fish are predictable if you understand the tides and know where to look. If you're new to sight-casting or shallow-water fishing, a guide for one or two days will teach you the patterns and help you locate productive water faster.
What's the typical size of redfish and seatrout here?
Redfish average eight to sixteen pounds, with occasional fish in the twenty-pound range. Spotted seatrout run smaller, typically ten to fourteen inches, though larger fish to eighteen inches are present. Both species are catchable year-round, but fall and spring produce the most consistent action.
Is there a bag limit for redfish and seatrout in Mississippi?
Yes. Mississippi has specific bag limits and size restrictions for both species. Check the current Mississippi Department of Marine Resources regulations before you fish; limits and sizes change, and they vary between state and federal waters. A quick call to the Ocean Springs Harbor or a local tackle shop will confirm the current rules.
