^^^^^ All starting to make sense now. I guess that's why when you fish for Giants with the commercial guys up in Gloucester, you can't keep any fish.
By law the boats have to sell them.
I guess if you as a for hire headboat or charter, or recreational angling permit, could keep 1 giant a year if you wanted to,
but you are not allowed to sell them.
Now we need to be able to indentify the different tunas... Here is a helpful chart I found on the NMFS site. Probably something handy to print out and have with you on the boat.
