Am I the only one feeling that a fish compendium might be useful, or if not, handy?

I'm a relatively new player to the game, still far from the endgame but i've sunk some time into it and i've fallen in love with the fishing mechanics.
Living near the sea, I've always grown fond of fishing and from time to time went fishing myself, and seeing as the fishing mechanics are improved from the basics of "casting your line and waiting for the fish to catch" that i find in most fishing minigames, i've enjoyed how the game depicts it.
However, i've started to feel like the game might need a Fish Compendium, much like the Gardening Hat? I'd like seeing if some of my theories i now have are correct, as where and when are some particular fish most active, and what bait i can use to attract a specific kind of fish, giving me the details obviosuly only after fishing it to promote experimenting.
I know most people downright hate fishing in videogames, but i kind of feel bad for developers that add a very cool and thoughtful mechanic only for new or even experienced player I've talked to saying they feel like it's mostly random.
There are my two cents, feel free to express critics or other ideas i might have flown over
