Fish Traps and Minnow Traps: Build, Set and Check
Funnel traps are the most buildable survival gear on this page — and the one most likely to be illegal where you are. Verified size, tagging and checking rules, and the drowning risk inside.

Warning
Traps kill turtles, mammals and waterfowl when they are left too long, and trap rules vary sharply by state and water. Mark your trap, check it at least daily, and confirm it is legal on your water before you build one.
- 01
Count your traps before you build them
South Carolina allows a recreational licensee no more than 2 traps; 3 or more require commercial licensing, and each trap needs a trap tag and a white floating marker. Texas allows minnow traps no longer than 24 inches with a throat no larger than 1 by 3 inches, for nongame fish and specified aquatic life only, marked with a visible non-orange buoy at least 6 by 3 inches and a gear tag. A tag valid for 6 days is not a 6-day catch-check interval.
- 02
Build to a size that is legal somewhere
North Carolina's inland minnow-trap rule caps the trap at 12 inches in diameter and 24 inches long with a funnel opening no more than 1 inch in diameter, requires all fish and animals to be removed daily, and requires labeling with a WRC customer number or your name and address. Other fish traps there are limited to three, only during authorized seasons in authorized waters.
- 03
Copy the design features, not just the shape
South Carolina's authorized designs include a cylindrical wire or textile trap no more than 6 feet long by 3 feet wide with mesh at least 1 by 1 inch and a prescribed closure or slit configuration, and a slat trap no more than 6 feet long by 2 feet wide or in diameter with a resting throat opening no more than 3 inches and prescribed small-fish escape gaps. Traps may not sit within 100 feet of tributary mouths, and freshwater crab-pot-style traps are not allowed.
- 04
A homemade excluder does not legalize a trap
A 'D-tube trap' or a DIY turtle excluder is not a recognized legal category, and adding one does not make an otherwise prohibited trap legal. Turtle excluders reduce some bycatch; they do not guarantee that no turtle enters, and air-breathing animals that do get inside must not remain trapped underwater.
- 05
Bait and placement are not one rule
Bread, grain and cut fish are the baits commonly taught, but no universal official bait recipe or best placement exists — bait legality varies. Do not transport live bait or use game fish as bait without checking your local rules.
- 06
Check it on the shortest schedule that applies
Daily removal of all fish and animals is a North Carolina minnow-trap rule, and South Carolina's trotline rule requires inspecting and removing fish at least every 24 hours. Treat daily checking as the humane floor, not a ceiling, and expect to find animals you must release.
- 07
Release is also regulated
Release protected and otherwise unlawful native catches promptly. But invasive-species rules may prohibit releasing or transporting live animals, so 'throw back everything you did not want' is not safe legal advice either.
