I was looking for an AddOn that could show me the skill required for all different waters and what fishes I could find in them, but I couldn't find any. Aren't there any AddOns like that at all? 'Cause it would be kind of good to have such a thing =P

Cartographer puts alot of different info on the main map. Mouse over a zone and it gives the recommended level, instances and the instance rec level, plus fishing level.

Go to http://files.wowace.com/sw-c.html and get the Cartographer_Fishing to add tracking notes to the map after you catch them. Needs Cartographer to work though.

Also Fishing Buddy lets you track the fish you caught per zone and the ratio of the catch. Also tracks thinks like bound trunks and potions caught.

thank you very much =]
