Adding 500 would be a good start to see if they can become established. 500 crays in your 0.5 ac is close to the density that Jamie Stocked (4000/3.5ac). White Rivers could get big enough that you & your roommate could eat some of them. If that thought interests you, then stock the White River crayfish.
