There are three ways to get rep with the Anglers. The daily quests you know about.
If you do any dungeons or scenarios you can select Anglers as your bonus rep and get get 600 or 400 rep for the first one you do each day.
Finally there are the Nat Pagle personal rep quest starting fish; there are three of these fish that you can catch, one from fresh water, one from salt water and one from sha touched water. The Pagle fish also give Anglers rep in addition to the Nat Pagle personal rep, one of my alts who was getting Nat's Hat (a hat with a large +fishing bonus that you can get once you are best friends with Nat Pagle) got to exalted with the Anglers without doing any of their dailies. Each fish is unique, so once you've caught one you can't catch another until you've turned in the quest.
Once you get to revered with the Anglers remember to buy the reputation doubling thing they sell. Most (all?) factions in MoP sell an object that when used doubles reputation gains with them for all characters on an account.
