Dear Judith
Probably is because the tuna is eaten a organism which contains carotenoid pigments specially astaxanthine (natural pigment present usually in algae, it is sell in artificial form as well for salmon culture) which gives the pink coloration to the fish flesh,

Dear all,
I have a question to ask, does any body know what actually causes Pink Tuna, and how can we analyse the content of whatever hazard that's causing it, if there is any as well?
I really need to know ASAP?
Cheers and Regards
