Simply tell you, there is no daily boundary, only jewelry fishing and cooking. Jewelry is picked up by trainers in Dalaran, fishing is picked up by the pool next to Union Bank, and cooking is picked up by cooking trainers. Just ask the guard. I suggest doing all three. Jewelry makes money, cooking and buying recipes for coins, I don't know what to do with fishing. Fishing is not connected yet, but it's good to do it.
