If you look up Aquaponics, you'll find quite a bit more.

Nishnabotna linked one of my favorites: Backyard Aquaponics, which has an awesome forum with sections dedicated to members established systems to different types of fish and plants that work well in Aquaponics and a lot more. I'm not a member, but I must confess that I dig through the forums every few months and dream. I am thinking about ordering the "International Information Package" from them.

A few more are:
Urban Aquaponics, which has an interesting blog on Aquaponics
and
Practical Aquaponics, which has a forum (Aquaponics HQ) where a few people show off their systems and exchange ideas.

Most of the good sites seem to be from people located in Australia.
