Bottom fishing means presenting bait on or just above the seabed where most predatory fish feed, and the whole game comes down to three things: the right rig, enough weight to hold the bottom, and bait that matches what the fish are eating. For most situations, start with a fish-finder (Carolina) rig when fish are skittish and want to mouth the bait, and switch to a hi-lo (two-hook dropper) rig when you want to cover two depths and find the school fast. Use just enough sinker to hold bottom in the current — too heavy and you lose bites, too light and you drag off the spot. Read the bottom with your rod tip and electronics: hard structure, edges, and drop-offs hold fish; clean featureless sand usually doesn't. Match hook size to the fish's mouth, keep your line tight enough to feel the take, and set when you feel weight, not at the first tap.
You can fish almost any bottom situation with two rigs. Learn to tie both blindfolded.
Fish-finder (Carolina) rig — the go-to for fish that pick up bait and run with it (redfish, snapper, cod, drum, catfish, flatfish). The sinker slides on the main line so the fish feels no resistance when it takes the bait.
Leader length matters: short (12–18 in) keeps bait pinned near bottom for flatfish; long (24–36 in) lets bait drift and wave for cruising fish.
Hi-lo (two-hook dropper / chicken rig) — best for prospecting, panfish-to-mid-size species, and any time you want two baits at slightly different heights. Two hooks stand off the line on dropper loops above a bottom sinker.
A dropper loop is tied by forming a loop in the line, passing the loop through the twisted opening you create with several wraps, and snugging it tight so the loop stands out perpendicular to the leader — that stiff stand-off is what keeps the hook from tangling the main line.
Pick sinker weight for the current and shape for the bottom.
For weight: in calm bays a 1/2–1 oz is plenty. In moderate current or light surf, 2–4 oz. In strong surf or deep fast water, 4–8 oz or more. The rule is simple — use the lightest weight that still holds your spot. If your sinker drifts and your line keeps belling out, go heavier. If you're missing soft takes, the sinker may be heavier than it needs to be.
Bottom fish eat what lives on the bottom, so fresh, natural bait usually beats artificials down there.
Two rules carry most days: fresher is better (re-bait often; washed-out bait stops producing), and match the size of the bait to the size of the mouth — a whole bunker for big drum, a thumbnail-size shrimp chunk for a finicky sheepshead. Hook cut bait so the cut, scent-leaking face is exposed. Thread worms onto the hook leaving a wiggling tail, or hook them once through the collar for maximum movement.
Size guide (hook size, then species): #6–#1 for panfish, perch, small flatfish; 1/0–3/0 for redfish, snapper, walleye, schoolie stripers, channel cats; 5/0–8/0 for big drum, grouper, large catfish, sharks. When in doubt, size to the bait and the fish's mouth, not to the fish's total weight.
Bottom fishing drags line across abrasive sand, shell, and rock, so leader is non-negotiable.
Match the leader to the structure: clean sand lets you fish light and stealthy; barnacle-crusted pilings and reef demand heavy leader you'd never use over open bottom.
Fish don't spread evenly across the seabed — they stack on structure and edges. Your job is to find those, then put bait in them.
Wherever current meets structure, you get an ambush point. Anchor or cast up-current so your bait washes naturally down into the strike zone.
The targets are the same; the approach differs.
From a boat, you can sit directly over structure. Anchor up-current and let baits trail back to a wreck, ledge, or hole, or drift slowly across an area to locate fish before anchoring. Use electronics to position precisely; a sliding sinker rig with just enough weight to touch bottom under the boat is ideal. In strong tide, heavier bank sinkers keep you vertical.
From shore, distance and reading water do the work the boat's position does. A surf rod (9–12 ft) with a pyramid or breakaway sinker reaches the trough beyond the first bar; a fish-finder rig lets a fish run without feeling the rod in a holder. Cast to the structure you read — the cut in the bar, the rock pile at the jetty base, the deep outside bend of a river. Prop the rod in a sand spike, keep a slight bow of line for soft takes, and watch the tip.
The best rig and freshest bait still need the fish to be feeding — and that turns on tide, current, and pressure. Bottom bites usually peak on moving water (the hours around tide changes inshore) and around dawn and dusk, so plan your session when conditions and structure line up.
