Gee makes a specific crawfish trap which is basically their minnow trap with a larger opening.
Gee trap picturesGee are my favorite brand of minnow trap. I have a bunch of them. One I have enlarged the opening a little to catch slightly larger fish. Note to anyone expanding the opening, it likely will make the trap illegal to use in public waters. Most minnow traps have a 1" opening because that is what most states limit it to.
Have you been eating any of them? Crawfish boil?
