Get past the marajuana ad stuff on this site, I don't know why it is there. Once past that, there is an interesting article about a local man here in P.O. WA who raises trout and grows veggies using aquaponics in a unique way.
Anyway, thought you (and everyone else) might find it interesting.
Sally, that article shows up on the website with all the pot advertisements simply because it has the word "hydroponics" in it. Here's the original source from the Kitsap Sun (much better source, much less distracting ads...)
one of the coolest set ups i read about had talapia growing underneath growing beds and the fish waste acted as a fertilizer while the fish had access to bugs.
the fish swam between the roots hanging down in their growing area.
