great read, cheers for the effort. I would add that they hit the BBQ very, very well. There is a 'bleed-out' point around the wrist of the tail and under the pectoral fin that will increase their table quality. Eaten raw is very nice too. I will also say that one single fish is a massive amount of actual food so unless you have a family of 20+ one tuna will do the trick nicely.
thanks Mark !
