As said before, fishes can be sold to other players, or traded in for beads. When you trade in fish for beads, you also obtain Lunia gold. You will often obtain more gold by trading in fish for beads than if you were to sell the fish in stacks, but because you can only trade for beads once per day it is often easier to sell off extra carps. There are fishing quests from Fishing Master Hemingway that give you items. Previously I mentioned dillies, but you can also get a variety of rare items that can be used or sold.
Beads can be traded in for items at the NPC Duran. You can only get one bead of a color per day, so it will take more than one day to get items with your beads.
So unless you want to burn through a bunch of high bait in half an hour while you are eating dinner, most people buy low baits and leave their character fishing whirly they are at school, work, or asleep.
