What do you do after 225 fishing?Follow

Depends on your side. I would suggest looking up the Trainers link on the left. It tells you, and gives you a link to the quest you need. Alternatively, go to thottbot.com and go to fishing. Same deal.

It involves talking to someone in IF, then to a fisherman in the Dustwallow Marsh, and then catching 4 quest fish all over the world. You then can get to 300.
