Crayfish-limit of 36-must be used in same water body where caught. May not be transported overland.
So if you can catch em in Lake Erie you can use em in Lake Erie. I would suggest trying a baitfish trap with dog food or fish scraps.
Good Luck
Ps- used to catch em in farm ponds in 80's and 90's, the whole no transport over land kinda screws that now though!
