According to researchers, there are three strains of YP. Northern, Southern and Great Plains. Some studies were done by the NCRAC. You can google that.
There were a couple fingerling producers in NC in 2011 based on a document by Tom Lasordo. Check with your gubment for current status.
I was in the Goldsboro area about 6 years ago. A local news station was featuring a new start up farm for Prawns and YP. Owner was pretty excited and was making a few bucks to boot! It was east of Goldsboro. I tried to find it one Saturday, but some of the roads aren't marked very well
I read some stuff a while ago, and if IIRC, the Southern strain will grow much faster and larger than our Northern counterparts. Unless, of course, you have the specialty Indiana and Nebraska strains
You can google this to verify or for more info. Right now I have a google, and, PDF headache
