Tom - Fish 'Poo' is not a biologically stable material, especially in the tropics. I suspect within hours, days or weeks the nutrients carried in the manure and urine will be converted to bacterial, plant and fish biomass. The resulting muck is more likely to represent plant material (algae). While in Angatuba, Sao Paulo State I visited a aquaculture (Tilapia and other indigenous species) facility owned by a goat dairy farmer. I've got nicely photo documented. He had a series of ponds and a clever diversion system from a stream. It's aquaculture use was as fish the secondary product for dairy waste.
