FYI driving native PK Shrimp from LA to MI is likely violating several state regulations without importation permits from all states. Interstate fish transfer/sales is strictly regulated and every state varies...they likely have eyes on this forum, too.
No doubt you are right. "In commerce" is the trigger for many such laws (unless noxious or protected species) whereas free sharing is much more loosely regulated in many cases. Louisiana is a surprisingly open state but that goes out the window when you cross state lines. A simple fishing license even allows you to sell a certain limit of reptiles and amphibians into the pet trade each day, if I read correctly
