The hell was square thinking with mining/botanist.

After a few hours of fishing you will be locked out of that fishing spot (no idea how long)

Just move a couple of yalms and restart fishing, there you go. ;-)

Also, picking the fish I want to catch sounds a bit silly to me to be honest, if you put your fishing rod in a lake you don't know what will bite, however you can use certain baits to attract certain fish - this is quite intuitive and does not need change.
Whereas as a miner or botanist you can see what items are on the tree/rock and specifically log or dig for it. It makes sense the way it is.
