I get White River Craws for stocking in ponds. I called my supplier earlier this week and they said now all they are getting is the smaller ones, they said wait until May/June for the larger ones if I was selling them for table fare.
Yes, they can grow to 3" in length in 3 months from hatching. I really like them for the goal of late spring harvest . By July the latest hatchers have stopped growing but there should be many >4.5" crays
