Trotline fishing is the practice of stretching one long line across the water and hanging many baited hooks from it, so one person fishes like a crew of dozens. We group trotlines with jug lines and limb lines under one name: set lines. All three keep fishing while you do something else. You check them instead of watching them. The outcome is more fish for less time and effort, which makes set lines a strong food skill for any family.
You may already fish with a rod and reel, or you may never have tied a hook. Either way, set lines reward simple gear and patience more than casting skill. They fit a weekend at the lake now and a long term food plan later. They put protein on the table without tying you to the bank all day.
Start by looking up the set line rules for your state. Then buy a spool of tarred nylon twine and a box of circle hooks. With those two items in hand, you can build every rig below.
What Set Lines Are and Why They Work
Learn the three set lines by name, and you can match each one to the water in front of you. Each one gives you more hooks in the water than your two hands could ever tend with rods. After the definitions come step by step directions for building and setting a trotline.
Three Lines, One Idea
We define a trotline as a long main line anchored at both ends, with short drop lines and hooks hanging from it every few feet. A jug line is a single baited line hanging from a floating jug that drifts or sits on open water. A limb line is a single baited line tied to a springy branch that hangs over the water.
All three share one idea. You bait many hooks, leave them, and come back to collect what bit. That is the heart of trotline fishing and every set line that follows it.
Why Catfish Take the Bait
Catfish hunt by smell and taste. Their whiskers and skin carry taste buds, so a strong bait on the bottom draws them from a long way off. Channel catfish, blue catfish, flatheads and bullheads all cruise the bottom at night, which is exactly where a trotline waits. Freshwater drum, carp and eels take set line baits too.
Bottom feeders also tend to swallow the bait and stay put. A circle hook then sets itself in the corner of the mouth as the fish pulls away. You get a hooked fish that is still alive and lively when you check the line at dawn.
Effort Saved
A rod and reel is a fine tool, and it teaches you where fish hold. It also asks for your full attention on one hook. A trotline puts 25 to 50 hooks in the water at once. You set it at dusk, sleep, and check it in the morning.
That trade matters to preppers. The hours you save go to cleaning fish, tending a garden or handling other food work. Set lines turn fishing from an all day sit into a quick morning chore.
Building and Setting Your Trotline Fishing Rig
Build a trotline once, and you own a rig that lasts for seasons. The steps below give you a line that sits on the bottom, holds big fish and stays where you put it. After the build comes how to choose a spot and run the line from a boat or the bank.
Build the Line
1. Cut the main line. Use #36 to #60 tarred nylon twine, about 50 to 100 feet long for a first line. The tar coating resists rot and keeps knots from slipping, so the line holds up through many wet nights.
2. Tie loops for the drop lines. Tie a small dropper loop or a knot every 24 to 36 inches along the main line. Even spacing lets each hook fish its own patch of bottom.
3. Make the drop lines. Cut drop lines 12 to 18 inches long from lighter twine. Keep each drop shorter than half the spacing between loops. Then two neighbors can never reach each other, and the hooks stay untangled.
4. Add hooks and swivels. Tie a 2/0 to 6/0 circle hook to one end of each drop line. Tie a barrel swivel or a trotline snap to the other end. The swivel lets a hooked fish spin without twisting the main line into knots. Snaps also let you clip drops on at the water and off for storage.
Anchor and Mark It
5. Weight the ends. Tie a 5 to 10 pound anchor to each end with a short rope. A brick, a sash weight or a sand-filled jug all work. Add a small sinker every 15 to 20 feet along the main line to keep it on the bottom in current.
6. Mark the ends with floats. Run a line from each anchor up to a bright float. The floats show you where the line lies, and they warn other boaters. On the bank, tie one end to a sturdy tree or a driven stake instead of an anchor.
Storage is the next problem a finished trotline creates. Loose hooks tangle into a bird nest fast. Clip each drop line onto the rim of a five gallon bucket in order, or stick each hook into a length of pool noodle. Then you lay the line out clean every time.
Choose the Spot
If you fish a river, set the line across a channel or angle it across a bend. Catfish travel the channel edges at night, and your hooks sit right in their path. If you fish a lake or pond, stretch the line along a drop-off where shallow flats fall into deeper water. Fish move up those slopes to feed after dark.
Set the line low enough that boats pass over it safely. A line on the bottom catches more fish and causes no trouble for other people on the water.
Run It from a Boat or the Bank
If you have a boat, start at one end float and lift the main line over the bow. Pull yourself along hand over hand, facing into the current, so the boat never drifts onto the hooks. Bait or check each drop as it comes up. Wear a life jacket and keep a sharp knife within easy reach. If the line snags the boat or a hook catches you, you can cut free in one move.
If you fish from the bank only, tie one end to shore and wade or toss the far end out with a heavy anchor. A shorter bank line covers less water, yet it sits right where fish come in shallow to feed at night. Checking it takes a few minutes, and you stay dry and safe on solid ground.
Jug Lines and Limb Lines
Add jugs and limb lines, and you fish the water a trotline cannot reach. Jugs cover wide, still water, and limb lines work tight banks lined with trees. Both are cheap to build. After them come the rules and safety habits that keep every set line legal.
Make Jugs from Bottles or Noodles
Rinse empty two liter bottles or gallon jugs and screw the caps on tight. Tie the line around the neck. Paint each jug a bright color and write your name on it. You can spot a bright jug from far across a lake.
Pool noodles make jugs that float and signal a bite at once. Cut a noodle into 12 to 18 inch sections. Run the line through the center hole and tie it to a washer at the top. When a fish pulls, the noodle tips upright or bobs under, and you see the strike from a distance.
Set the Depth
Tie 3 to 8 feet of line under each jug. Add a sinker about a foot above the hook so the bait hangs straight down. In summer, catfish often suspend near the thermocline, so a shorter line can catch more fish. In cooler months, let the bait hang close to the bottom.
Set a few jugs at different depths on your first trip. The jug that catches tells you where the fish are feeding, and you rig the rest to match.
Follow Drifting Jugs
Release jugs upwind or upstream of a flat or a channel. Let the breeze or current carry them across the fish. Stay close in a boat or kayak and keep every jug in sight. Collect them as they reach the far shore.
To retrieve a jug with a fish on, ease up beside it. Grab the jug, then pull the line in hand over hand. Have a net ready for the last few feet, because a big catfish often makes one hard run at the boat.
Tie a Limb Line
Find a live, green branch about as thick as your thumb that hangs over the water. Tie 2 to 4 feet of line to it, so the bait hangs a foot or so under the surface. The branch bends like a rod when a fish strikes. That spring tires the fish and keeps the hook from tearing out.
Limb lines suit the bank angler perfectly. A shore crowded with overhanging trees looks like poor fishing ground to many people. In fact, every one of those branches is a free rod holder sitting over shaded water where fish rest.
Baits That Stay on the Hook
Set line bait has to last all night. Cut shad or cut carp with the skin left on holds well and leaks scent for hours. Chunks of hot dog stay firm and cost little. Catfish soap baits stay on almost forever. Live bait such as small sunfish or goldfish keeps working as long as it lives, where your state allows it. Soft chicken liver catches fish too. Wrap it in a scrap of bait netting or thread to keep it on.
Running Lines Legally and Safely
Follow the rules and handle hooks with care, and you keep your catch and your hands in good shape. Good habits here protect you, your family and the fishery you depend on. After the rules come three steps to put your first set lines in the water.
Hook Limits, Tags and Checks
States limit how many hooks you can fish on each line and in total. Most require a tag on every trotline, jug and limb line with your name, address or license number. Many set a checking interval, often once every 24 hours. Some lakes and rivers ban set lines outright. Others protect game fish such as bass, which you must release.
Rules change from state to state and from year to year. Check your state wildlife agency before every season. Read the rules on bait too, since many states ban live game fish as bait. Pull your lines when you leave, so no hooks keep fishing unattended. Legal trotline fishing keeps fish in the water for next year.
Handle Hooks and Loaded Lines
Wear gloves and lift each drop by the line, never by the hook. Keep your hands on the upstream side of the drops, so current swings the hooks away from you. Carry hook cutters and a knife on your belt. If a hook buries in skin past the barb, cut the shank and seek care.
A loaded line pulls hard. Let a big fish tire on the line before you lift it. Bring the fish in with a net or by the lower jaw, and keep the line off your wrists and fingers. Unhook each fish, rebait the drop, and move on to the next one.
Your First Three Steps
1. Look up the set line rules for your state, including hook limits, tag wording and checking times.
2. Build one 25 hook trotline and four pool noodle jugs, then tag each one.
3. Set the lines at dusk on a nearby channel or drop-off, and check them at first light.
Set lines are one part of a full fishing kit. The Survival Fishing guide from Prepper Life covers the wider skill set, from finding fish to cooking the catch.
