I realize that shrimps and lobsters and catfish and other things I voluntarily eat do in fact eat poop and all sorts of horrid things. But somehow this just does not sound sanitary to me.
I am thinking of setting up an aquaponics system for tilapia and freshwater shrimp using my barn roof runoff, a cistern, a reed bed and a big recirculating pump, but I think the tilapia are going to be fed grass clippings, mosquito larvae and weeds, just for hygiene purposes, yanno?
Besides, most of our chicken poo is thoroughly composted before being applied to the veggie garden...It's not fresh or anything.
