If you've read through much of my material, you'll see that I write a decent amount of content about beating tags (tight-aggressive opponents).  Although that information is important to know in order to develop a well-rounded poker game, you should be spending the majority of your time playing against the fish.

It might look like there's an emphasis on playing against and beating up on tags at BeatNoLimit.com, but that's just because there's so much more strategy involved in playing against sophisticated players.  There's not as much strategy involved in beating the fish. 

On top of that, the types of fish you encounter as you move up in stakes will change.  Some of the tags we talk about in .25/.50 NL may very well be fish at 3/6 NL.  So you see, it's important to know how to beat all types of opponents.  Even so, you should be spending the majority of your time playing against the fish.

It's funny how much more money you can make by taking the time to play against the fish.  I remember one month when I spent way more effort than normal to chase the fish.

It went way beyond looking for the tables with the highest average pot size.  That month I became a fish stalker.  I kept notes on the fish, I searched for their names, I opened up my PokerTracker database and looked for players with fishy stats.  I did everything I could to play against bad opponents.  More than once I got comments in the chat box from people who saw me following them around.  I didn't care though; I was making money.

And you know what?  It worked!  I had the best month of poker I'd ever had up to that point.  On top of that, my variance was lower.  I didn't have to worry about getting it in with small edges or trying to decide on whether or not I should 4-bet this light 3-better or whatever.  I just went out, waited for strong hands and bet them.  My decisions were easier and my profits bigger.

I'm guessing you're at BeatNoLimit.com to work on your game, so this might sound like a strategy that's counterintuitive to improvement.  I mean, shouldn't you play against strong opponents to make yourself a better player?  Well, not really.  Jumping right in and playing against strong opponents is just as likely to frustrate you and drain your bankroll as it is to improve your game.

What works best is to methodically and mercilessly hunt the fish at your stakes.  By doing so, you're going to improve your ability to spot fish and exploit them.  But that's not where the benefits end.

The extra money you make by playing against the fish will enable you to move up in stakes faster and get experience in bigger games.  It's a gradual process, but eventually you'll be beating up on "fish" that would have smashed you in the past.

It really is worthwhile to chase the fish.  If you make the extra effort to find them and chase them, it will increase your bottom line.  Fish keep the poker games alive so make sure to be the first person in line.

Some of the fishiest poker sites I've found tend to be the smaller ones.  They might not have the raw numbers as some of the more established sites, but they definitely have a nice ratio of fish to tags.

A couple sites that come to mind are Cake Poker and Carbon Poker.  In addition to the fish they have some pretty big first time deposit bonuses.  If you want to jumpstart your poker career, one of those two sites might be worth a look.
