ok... i just called nc wildlife, the number for regulations is 919-707-0030, for jug lines, they only thing regulated is no live bait, the jug can be of any color as long as its not a peice of trash (glass bottle, or can), and it doesn't need to be anchored. you can put a weight on it, but it can be free floating, they don't have to be marked but wildlife prefers them to be marked just incase they need to find out who's it is, and the wildlife officer said to just make sure to collect them all so that there aren't jugs floating around everywhere... for set hooks, no live bait, has to be marked with name and address or name and vessel registration number, or name and initials... trotlines, any color can be used for the bouys, has to be parellel to the nearest shore, can't impede others from using the water, no max length and no max amount of hooks, has to be anchored, bouys have to have owners name and address, or name and vessel registration number, or name and initials... thats all i got from the wildlife officer, and i asked for the highest ranking officer in the office just to make sure i got the right answers... lol
