I need some answers on spacing the hooks on the trotlines cuz I normally would know by looking the fishing rules book and no one seems to have one. K-mart, Wally-mart, a couple of sports stores and bait shops, all are out of them and I just want to know what is the rules of spacing the hooks on the trotlines? I have been told 18", 20" and 24". My last time I had them at 20"-24" apart. Also am aware that must have your name , and/or address, or drivers license on the end of the line. Can anyone tell me what is the legal spacing please? Thanks.
