How much does permit cost and or license cost
Good luck with that. I looked into it. Only 3 labs use the blood. I called all 3. Only one offered to buy raw crabs (alive). I have the medical know how to extract the blood myself but they would not buy blood - only crabs. So unless you can collect a TON of them and ship them to a lab alive - it isn't worth it. Blue blood worth more than gold though.
