It sounds attractive that you can get some additional World of Warcraft Gold easily in Fishing. World of Warcraft Fishing is different f Aion mining that requires a big loss of money. You can try Finshing in Windurst where your skills will be raised soon.
You should buy a Glass Fiber Fishing Rod 2.1k in Windurst first that will cost you about 3000 to 4000 World of Warcraft Gold to begin with. Then you can start making money by fishing small fish that will get lots of bites and work.
Port San d'Oria is a good place to start. Windurst Woods is also a good place. You can head up to the bridge by the Dhamel farm and fishing f Aion that bridge facing south. The other option is to buy a World of Warcraft Gold abiki Rig. These can catch you up to three fishes at a time, but they cost a little more than a ball of insect paste. Port Windurst is a great place to go. By the Fishing guild you can catch up to three bastore sardines easily at level 0 or level 1 fishing skill with image enhancement f Aion the little taru there. Try for Bastore Sardines.
