Takitaro, Megalodon, Mazlaya Marlin, Aetherlouse, and Worm of Nym are all "missing" the Crafting Material note in their item text. Not sure if it's necessarily a localization oversight or if it's that way on the JP client as well. Either way, would be nice if this could get retroactively added for people like me who look for that little blurb when we decide to keep or sell a fish :)
