Poesidon, in theory Ewest is right. Get the best fish money can buy.
From a practical standpoint though, many of our southern states have fish and stocking plans which will serve most people well.
The typical bass/bluegill/readear/channel cat is a proven winner. If you want the finest of those species, there are some great providers right here. But most state fish will manage nicely enough, in my experience.
So if your budget is maxed or broken, the state fish will be OK. Or you could wait a year or so, and save up.
