I happened to be awake & available to play wow this morning from 4am-5am & I caught 15 Golden Darter in 1 hr. at Allerian Stronghold in Terrokar Forest.. Started with base skill of 300, which ended up @ 307.. Had a friend with Engineering skill make me the Fish Attractor lures (+100 fishing 10 mins.) .. -=>By the way you only need Engineering skill of 125 to make these lures, mats are usually available cheap on the AH<=-  I would assume these fish are available in their given location(s) between 12a & 12p server time daily.

P.S. - My fishing rod as of right now sucks, yes (only +5), but I intend to win the Arcanite Fishing Rod tomorrow (Server - Eredar) ..  I'll update with that afterwards. :)
