This may end up being a hot topic and potentially not get put in (like all my other suggestions)
As part of the update when you reach certain milestones in the Hunters Call you unlock the ability to buy new fishing rod skins, these skins will give you increased chances at trophy fish with some higher level skins being able to pull up "treasure loot" which could include: gold pouches, message in a bottle and small trinkets (the treasure loot could be made available as part of the distinction rods)
bestiary of where to find certain animals and fish, locked behind the captained ship (and privated ship if that other idea goes through) this will only pop up if you have caught and cooked the meat of the animal, for fish it will also show what bait you can use to catch it if it is a fish that can be caught with bait, again when you figure out which bait it is then it will tell you. With this you will be able to tell how many cookable meats and fish there are in the game but you wouldn't be able to tell what it is or where it is findable until you catch it.
