I just went through the fishing regs again for the 3rd or 4th time. My interpretation is you can seine crayfish and use them for bait. Someone correct me if I'm wrong. I'm too poor to pay a fine and too old to go to jail!
Yes, thats correct. You can trap them too, (I do every summer for dinner) and all you need on your traps is name and number. I think its different for keeping them west of the divide though.
