just to add in my 2 cents. i needed to fish them to get my cooking skill from 250-275 so i read up on where to find them. i went to skettis (black wing lake or something) you can only reach by flying mount but since there are dailies there i am going to try a diffrent body of water to avoid being ganked. i can onyl get them from the mix highland schools, iam sure there is the very rare chance to get one from jsut fishing in any elevated body of water but i wouldnt bet on it. i had 375 fishing skill, +20 to pole, and a +75 lure..wasnt about to waste a +100 if i didnt have to. and in the 7mins left on my lure when i started in the school i came up with 7 crawdads, and the time does take into account moving to diffrent schools, and fighting the water mobs that attacked me. hope this helps
