Get yourself to The Barrens and into the Wailing Caverns instance. You can catch the Deviate fish outside the instance and even in the pool outside the cave but you'd be crazy to fish there as alliance since this is horde land and a popular low level instance. There are several safe spots in the instance but Ive found for ease and convenience, that the stream just past the first batch of raptors works great. There is a yellow named elite turtle that just trucks around doing laps in the pool and 1 wandering ooze you have to deal with. Other then that, its a totally safe spot. The turtle is non aggro but after he struts by for the 25th time you'll find yourself wanting to make turtle soup.
