What makes a good bait for traps? I just got started trappping these things lastnight,I caught 3 middle to large size Red Swamp crawdads off of some bluegill someone had used as cut bait for fishing. It seemed to work good but I don't think your allowed to catch and kill bluegill for bait,or perhaps that is just a rule for pay lakes,I do not know. Today after eating crawdad for the first time, I went out and made three more traps,now they are sitting in a crawfish infested pound that my grandfather use to catch them from. Needless to say my goal is to eat my body weight in crawdads before the summer is out,they are fine eating and the are fun to catch,plus they are free. Just how big can these guys get? I read somewhere that they don't turn red untill unless they are dead or cooked,but once as a young lad I seen the Crawdad of all Crawdads to come,very lobster like,alive,well and red as can be near a roadside ditch.I kick myself now as I look back on it for letting that one go.
