Learn bottom fishing techniques for freshwater and saltwater. Discover the rigs, gear, and pro tips to catch catfish, grouper, snapper, and more.
Some of the biggest, heaviest fish in both freshwater and saltwater spend most of their lives close to the bottom. That’s where the food is: crawfish, worms, crabs, mussels, and baitfish hugging the structure. Bottom fishing is one of the oldest, simplest, and most effective ways to target them and it works just as well for catfish on a river as it does for grouper in the Gulf.
Predators are opportunists. They patrol ledges, holes, and reefs, waiting for an easy meal that’s already on the bottom. Presenting your bait naturally in that zone means you’re fishing where they live.
Unlike some techniques that require finesse or fancy casts, bottom fishing is straightforward: keep your bait on or just above the bottom, and hold on tight.
Step 1: Pick Your Spot
Freshwater: Deep holes, undercut banks, submerged timber.
Saltwater: Reefs, wrecks, ledges, or channels.
Step 2: Rig Up
Simple Bottom Rig: Sinker on the end of the line, hook tied above it.
Fish Finder Rig: Sliding sinker, swivel, leader, and hook keeps bait more natural.
Drop Shot Rig: Suspends bait just off the bottom deadly for bass.
Step 3: Present Bait Naturally
Use live bait (worms, minnows, shrimp, cut bait) or bottom lures (jigs, soft plastics).
Let scent and movement do the work.
Freshwater: Catfish, carp, bass, walleye.
Saltwater: Grouper, snapper, flounder, halibut, red drum.
Rod: Medium-heavy to heavy rods with backbone for big hooksets.
Reel: Spinning or conventional, depending on target size.
Line: Braid for strength and sensitivity, fluorocarbon leader for stealth.
Weights: Vary depending on depth and current from split shot in ponds to 8-ounce sinkers offshore.
