Biloxi Back Bay Trout Fishing: A Winter Angler's Playbook
Cold Weather, Hot Trout Fishing
When temperatures drop across the Mississippi coast, speckled trout leave the open waters of Mississippi Sound and funnel into Biloxi's Back Bay and the tidal bayous feeding it. This seasonal migration creates one of the most concentrated trout fisheries on the Gulf Coast, putting hundreds of fish within casting range of a small boat or kayak in sheltered water barely a mile from the Biloxi casinos.
Why Back Bay Holds Winter Trout
Back Bay of Biloxi is a shallow, semi-enclosed body of water fed by the Biloxi River and Tuxachanie Creek on its northern end and opening to Mississippi Sound on the south. The bay's average depth of 5–7 feet and its dark, tannin-stained water absorb heat more efficiently than the open sound, keeping temperatures 3–5 degrees warmer during cold snaps. Trout seek this thermal refuge, and they don't leave until spring warming pulls them back to the barrier islands.
Key Spots in Back Bay
| Location | Why It Holds Fish | Best Approach |
|---|---|---|
| Deer Island Shoreline (south side) | Protected from north wind, deep channel edge | Drift along the shoreline casting toward the island |
| Biloxi River Mouth | Fresh water mixes with salt, creating current seams | Anchor at the river mouth on outgoing tide |
| Point Cadet Marina area | Dock pilings, rip-rap, nearby channel | Work pilings with live shrimp or soft plastics |
| Hiller Park Shoreline | Grass flats transition to deeper water | Wade or kayak at dawn |
| I-110 Bridge Pilings | Current break, structure, depth change | Vertical jig near pilings on moving tide |
Back Bay after a cold front is the best trout fishing you'll find in Mississippi. The fish pack into the deeper bends so tight you'll catch them on every cast. January and February mornings when the air temperature is in the 40s and the water is in the mid-50s—that's prime time.
Techniques for Cold-Water Trout
Winter trout are sluggish compared to their warm-season counterparts. They won't chase fast-moving lures or travel far to eat. Slow your presentation down dramatically:
- Live shrimp under a popping cork: Set the cork 2–3 feet above the shrimp, pop it once, and let it sit for 15–20 seconds between pops
- Soft plastic on 1/8 oz jig head: Barely twitch the rod tip, letting the jig hover just off bottom—Speckled Trout in Biloxi inhale slow-falling presentations in cold water
- Suspending twitch baits (MirrOlure MR17, Rapala X-Rap): Twitch-twitch-pause for 5–10 seconds—let the bait hang in the strike zone
Tackle Adjustments
Scale down from summer tackle. Winter trout in Back Bay average 14–18 inches with larger fish to 24 inches mixed in. A 6'6" to 7' medium-light spinning rod with a 2500-size reel, 8 lb braided main line, and 12–15 lb fluorocarbon leader provides the sensitivity needed to detect subtle cold-water strikes. Redfish in Biloxi also frequent Back Bay during winter—keep a slightly heavier rod rigged in case a bull red finds your trout bait.
Month-by-Month Breakdown
November: Trout begin moving into Back Bay as water cools below 68°F. Mixed schools of trout and white trout feed actively along channel edges. December: The migration is in full swing. Larger trout (20+ inches) show up consistently, especially around Deer Island. January–February: Peak concentration. Cold fronts push fish into the deepest holes and creek bends. Post-frontal days with sunshine are the most productive. March: As water warms past 62°F, trout begin dispersing back toward the sound and the barrier islands.
