Correct, you have to have date set out and name, address like a jug line or trotline.
Not sure what system you are using for your limb line but I made my own version of a "port arthur" limb line out of PVC. Works awesome and generally once you have them set to where you want them you can go to just about any tree limb and it will be the right length unless the limb is unusually high or low to the water surface. I added a small piece of swim noodle to the PVC so my hook and leader can just wrap around the pvc and hook into the swim noodle so I can deploy it very quickly and pick it up quickly almost never having to adjust the depth! And you can fit several in a 3 gallon bucket without having a big mess. I use a cheap carabiner clip on the securement end so I can throw it around the branch and hook it to itself rather than tie it to the branch. Just some ideas for you!
