There is a reason that every anime and such-inspired game treats it like a legendary fish.
Its because the fish meat itself is awesome. That said, its a shame that we won't have many of them soon. The oceans are dying. Soon, the only remaining viable fish (not just tuna either) will probably be canned mush.
Oh, and don't suggest farmed stuff. ANY farmed fish is fed stuff from fishing fleets, often Chinese ones.
