Fish Desynth

[Nyalia]

This is a good source of desynthesis info:
http://na.ff14angler.com/desynthesized

While that site is really awesome, it's missing at least four unique items (Ti Leaf Lei (Frilled Shark), Summer Sandals (Shark Tuna), Oschon Roselle Capeline (unknown), Gold Roselle Capeline (Toramafish)). Also, I'm given to understand that a fish can drop Minium, which is totally plausible since they give so much sand. I wouldn't be surprised if a fish gave Emery too. And, there's a fish that drops Ferberite (Armorer) which is sorta worth mentioning.

EDIT: I take it back, that site is AWESOME! They have hundreds-thousands of catch times and desynth results recorded for some of these, very nice for figuring out exact times! Sadly, their comments are in Japanese, which is where the weather and minimum gathering info is recorded. I'll compile the data from translating the Japanese and let ya'll know what their data suggests.
