Very, very seriously considering building an outdoor, year-round, unplugged, aquaponics system in Missoula MT. Very audacious, I know, but I think there's a guy in Stevi doing it. I have so many ideas that I need to get validated but the question burning in my loins right now is this... is it OK (from a human and critter health standpoint) to feed tilapia and/or perch and/or trout straight up goat manure? Or must it compost first? Or must I take it from manure to compost to duckweed (for example) to fish food? And if it must compost first, that is OK, but if I am hoping to get some heat for the "greenhouse" (I use this term loosely) from the composting manure, should it be in one of those spinny barrel things or should it be out in the open so it can release the heat better? I am lazy, so I am not very into the idea of turning the manure by shovel, but if it will keep my "greenhouse" warm, I guess I can deal with that.
I know there is a lot of other things going on here, such as how do I keep the aqua from freezing, blah blah blah etc, but I have those are for another time and place. My question relates only to the matter of feeding manure or compost to various species of fish.
Does this question belong in composting? I figured since its about fish it would go in critters, but there's no fish forum. And since I'm talking about goats... well...
First post, new to the philosophy, please be nice! Thanks!
