Okay. Dude. I've been trying to research this for days now. Several times in my google searches, one of the top google results turned out to be THIS THREAD. Wtf. There's got to be more people out there trying this, you gotta be kidding me...
I've found a few references to "vermiponics", which involves compost worms-- but traditional terrestrial worms in terrestrial compost, trying to figure out how to cope with the extra wetness of dribbling a limited amount of water through their worm bin, OR by simply sticking worms in the top layer of a hydroponic grow bed. Clogging up my grow bed with compost gunk or risking drowning some earthworms is not what I had in mind.
Then there's "compost tea", which is less about composting and more about culturing microorganisms, primarily for supplementing soil-- and not at all about creating nutrients.
In terms of true aquatic compost, utilizing aquatic animals, I can find nothing.
I'm about this close to just calling up Berkeley and asking them about it. If I was a master's student in biology looking for a thesis I'd have my work cut out for me.
