Top Saltwater Bottom Fishing Rigs for Successful Fishing Trips

by Pablo Koch-Schick

If you’re looking for hard-fighting fish and nonstop action, bottom fishing is one of the best ways to catch fish in saltwater. Whether you’re fishing deep offshore ledges or working a reef in St. Petersburg, FL, the right bottom fishing rig makes all the difference.

Bottom fishing isn’t just about dropping a line and hoping for the best. It’s about choosing the right setup, reading the water, and knowing what’s biting. From grouper to mutton snapper, the Gulf Coast is packed with bottom species that will put your gear to the test.

At Reel Coquina Fishing Charters, we take the guesswork out of bottom fishing. Our experienced captain knows where the big fish are and what fishing rigs work best to land them. In this guide, we’ll break down the best saltwater fishing rigs, the gear you need, and expert fishing tips to help you make the most of your next fishing trip.

What is Bottom Fishing?

If you love the thrill of feeling a fish slam your bait and the tug-of-war that follows, bottom fishing is right up your alley. Whether you're dropping lines over a deep offshore reef or working the ledges of Tampa Bay, this technique is one of the best ways to catch fish in saltwater fishing.

Bottom fishing is all about getting your bait fish down to the ocean floor where bottom species like grouper, snapper, and amberjack lurk. These fish don’t chase bait up high, they sit tight near the bottom structure, waiting for an easy meal. That’s where bottom fishing rigs come in.

  • Works in both deep and shallow waters – Whether fishing deep drop offshore or targeting reefs near St. Pete, bottom fishing is effective in many environments.

  • Targets a variety of fish – Everything from mutton snapper to giant grouper can be caught using this method.

  • Popular in Florida’s Gulf Coast – Many anglers in St. Petersburg, FL love bottom fishing because it’s reliable, fun, and produces big fish.

At Reel Coquina, we specialize in taking anglers out to some of the best bottom fishing spots in St. Pete and the surrounding Gulf waters. Whether you're a seasoned pro or just getting started, we make sure you’re in the right place with the right fishing rig to land your next trophy fish.

Gear for Bottom Fishing

Before we get into saltwater fishing rigs, let’s talk about the must-have gear for bottom fishing. The right setup can mean the difference between a slow day and a trophy catch.

  • Fishing Rod & Reel – A medium to heavy-action fishing rod paired with a sturdy fishing reel is key for handling big fish. Conventional reels with high line capacity are ideal for deep water fishing.

  • Main Line & Leader Line – Braided main line provides the strength needed to pull fish out of reefs, while a fluorocarbon leader line is nearly invisible underwater, giving you an edge with cautious fish.

  • Hooks – Circle hooks are a must for bottom fishing, as they provide solid hook sets and are better for catch-and-release. J hooks can also be used but require a strong hookset from the angler.

  • Sinkers (Bank Sinker or Egg Sinker) – Your bottom fishing rig needs a sinker to keep the bait in the water column. A bank sinker is great for deep drop fishing, while an egg sinker works well when you want the bait to move naturally.

  • Bait – Live bait rigs are highly effective, especially with blue runners, pinfish, or pilchards. Cut dead bait, squid, or fishing lures also work well depending on your target species.

  • Terminal Tackle – Items like barrel swivels, three-way swivels, and clips help prevent line twists and keep rigs running smoothly.

Best Saltwater Bottom Fishing Rigs

Now that you’re geared up, let’s talk about the best bottom fishing rigs. Different rigs work best for different species, depths, and currents. Knowing which fishing rig to use can seriously up your game, whether you’re fishing offshore in deep water or working nearshore reefs in St. Petersburg, FL.

1. Three-Way Swivel Rig – The Heavyweight Contender

Perfect for big live bait, the three-way swivel rig keeps your bait slightly off the bottom, making it irresistible to big fish like grouper and amberjack.

Setup:

  • Three-way swivel

  • Leader line

  • Circle hook

  • Bank sinker (to hold the bait near the bottom)

Best for catching: Mutton snapper, giant grouper, blue runners

Why use it? Keeps your live bait rigs in the strike zone while preventing snags on rocky bottoms.

2. Knocker Rig – The Snapper Slayer

A favorite for reef bottom fishing, the knocker rig lets the egg sinker slide freely, allowing the bait fish to move naturally. This is a great rig for mutton snapper and yellowtail snapper, which are known to be cautious feeders.

Setup:

  • Egg sinker (slides freely on the leader)

  • Barrel swivel

  • Fluorocarbon leader line

  • Circle hook

Best for catching: Mutton snapper, yellowtail snapper, grouper

Why use it? The sliding sinker lets the fish take the bait without feeling resistance, making it a great rig for tricky reef dwellers.

Setup:

  • Sliding sinker clip

  • Barrel swivel

  • Leader line

  • Circle hook

Best for catching: Striped bass, flounder, drum

Why use it? The sliding weight lets the fish take the bait before feeling resistance, leading to more successful hookups.

4. Carolina Rig – The Stealthy Hunter

Setup:

  • Egg sinker

  • Swivel

  • Leader line

  • J hook

Best for catching: Snapper, grouper, porgy

Why use it? The long leader and precise cast make this rig extremely effective for cautious fish.

A must-have for deep drop fishing, the chicken rig allows you to fish with two hooks at different depths, maximizing your chances of landing a bite.

Setup:

  • Main line with two hooks tied at different intervals

  • Bank sinker

  • Leader line

Best for catching: Tilefish, sea bass, porgy

Best Practices for Bottom Fishing

Now that you know the best saltwater fishing rigs, let’s cover the strategies that will help you land more fish. Bottom fishing is about more than just dropping bait, it requires the right approach, positioning, and technique.

Use Long Leaders When Fish Are Finicky

  • A long leader increases bites from pressured fish, especially on reefs where they’ve seen plenty of tackle before.

  • Allows the bait fish to move more freely, making it look natural in the water column.

  • Works best when targeting species like snapper, grouper, and mutton snapper.

Secure Your Sinker Before Moving

  • If you’re repositioning, always secure your sinker to avoid damage to your fishing rod or boat.

  • Instead of hooking the bottom fishing rig to the rod’s hook keeper, wrap the leader around the reel foot and attach it to the frame.

  • This keeps the entire rig secure and prevents the sinker from bouncing around while underway.

Pay Attention to Bottom Structure and Current

  • Most anglers know that fish love bottom structure - reefs, wrecks, ledges, and even deep holes are prime locations.

  • The best fishing techniques involve positioning your bait up-current so that it drifts naturally into the strike zone.

  • If the current is too strong, switch to a heavier bank sinker or use a three-way swivel rig to keep the bait in place.

Adjust Your Rig Based on Depth and Conditions

  • In deep water, a deep drop rig or chicken rig is more effective for keeping multiple baits at different depths.

  • For surf fishing, a fish finder rig works well, allowing the bait to move with the current while keeping it close to the bottom.

  • If fishing near a structure, a knocker rig helps the bait stay closer to the bottom without getting snagged.

Use the Right Bait for the Target Species

  • Live bait rigs with blue runners, pinfish, or pilchards work best for predatory fish like grouper and amberjack.

  • Dead bait such as squid, cut mullet, or ballyhoo is perfect for bottom dwellers like snapper and sea bass.

  • Fishing lures like jigs and soft plastics can also be effective, especially when targeting active feeders.

Common Bottom Fishing Catches

One of the best things about bottom fishing is the variety of species you can catch. Whether you're fishing offshore in deep water or working the reefs, you never know what might be on the other end of your line. Here are some of the most common bottom species you’ll encounter.

Nearshore Species

These fish are commonly found on reefs, ledges, and rocky bottoms closer to shore.

  • Flounder – Masters of camouflage, these ambush predators love sandy bottoms near reefs.

  • Sea Bass – Aggressive and abundant, they hit both live bait and fishing lures.

  • Red & Black Drum – Hard fighters that thrive around bottom structure inshore and nearshore.

Offshore Species

Fishing in deep water offshore opens the door to larger, harder-fighting fish.

  • Mutton Snapper – A prized fish that requires stealthy bottom fishing rigs and precise bait presentation.

  • Giant Grouper – True heavyweights that demand sturdy fishing rods and reels with high drag.

  • Amberjack – Also known as “reef donkeys” for their raw power, these fish put up serious fights.

  • Tilefish – Found in deep drop waters, they prefer sandy bottoms and are highly sought after for their mild, delicious meat.

Wreck & Reef Dwellers

Fishing bottom structures like sunken wrecks and artificial reefs can yield impressive catches.

  • Gag Grouper – A favorite among many anglers, known for their powerful runs back to structure.

  • Hogfish – Typically caught using live bait rigs, these fish are a delicacy in Florida.

  • Porgy – A smaller but tasty fish that thrives on reefs and ledges.
