No. Couple of problems. If you are doing this in the leveling zone, all you get is White Meat. If you do this in a Silver or Gold instance, then you get some raw mats that you can refine.
And, there are better places to farm for the raw mats and not have to put up with Campers. Mudcrabs on the Beach for instance. Much much better source, as you can also get loot to decon or sell. And a lot more exp to boot if they are on or near level.
