The lake elevated above The alliance zone and skettis has tons of these spawns... they look like a welt on the surface of the water and if you have a good video card u can see the circling fish beyond the surface.. i catch about 35-40 of these a day early in the morning when everyone is in bed and all the spawns are fresh, right after server maintenance is also a good time to catch these spawns. Currently 375 fishing +20 pole +100 lure and +2 to gloves.  These sell a little better uncooked but cooked give a 30 stamina buff, great for raids and is also one of the easiest ways to cap cooking at 375.  good luck!
