Fisherman adjustments?

[Magis]

5) As it stands, the majority of fish we gather aren't used for anything. I would like to see some more things created using fish. Fishbone jewelry, more food, etc. Perhaps we can craft "oils" using various fish and these oils can be applied to other crafted items?

Can't remember where, but I recall Yoshi saying he didn't want fishing to effect the economy and it should be a "relaxing" thing.
