Questions about fishing

[MongoJerry]

Zone Level to Fishing skill:

1-10 to 50
11-20 to 100
21-30 to 150
31-40 to 200
41-50 to 250
51-60 to 300

That doesn't seem right. Out in the open ocean water in Azshara, I've had over 325 fishing skill with lures and was told "Fishing Skill Not High Enough." The more inland (lower level areas) could be fished by me but not the farther open ocean areas. I'm pretty sure that there are lots of places where you have to have 400+ fishing skill to fish in them.
