You can go to 300 in fishing anywhere, regardless of the level of difficulty where you're trying to fish. If you're not interested in raising your cooking along with your fishing, you can sit in any newbie area with a body of water and fish your way to 300.
If you want to raise your cooking along with your fishing, follow this guide:

you can almost do that, but you still have to make some side trips. AT L20, you have to go to Booty Bay to buy the book that gets you past 150, and at L35, you have to go to Dustwallow Marsh to get the quest that gets you past 225. That quest makes you fish in Desolace, Feralas, Stranglethorn Vale, and the Swamp of Sorrows. You can't just sit in a newbie area until 300 - but you can return to the newbie area after buying the book and completing the quest. You won't make much money and your cooking skill will suck if you go back to the newbie area to skill up.
