You can tell that you're eating tuna, it can't be compared to the products that exist in the supermarket. From Greek seas and not from the Pacific Ocean and the aftermath of Fukushima

No relationship with supermarket canned products. You can tell it's more fishy and has a different taste. The Pacific has issues from what I read and most tunas are caught there except for one that is caught in Ecuador. The island tuna is caught in clean seas and surely its price will be higher, but so is its quality
