I am excited to discover your website. If you respond, I will send you some photos of my fish & oyster aqufarm, all on land. I depend on the fish to culture phytoplankton in ponds and I pump the pond water through raceways to not only feed the shelfish but to convert ammonia & nitrites from both species into nitrates that return to enhance the cultures. Where your passion and mine will meet is when I have installed an anaerobic biodigester to be fed with high carbon, aerobically-derived compost that untilizes the fish guts and other wastes. Of course, after stripping the methane & CO2 — the former to run a generator, the latter to also enhance the cultures –from the digester, the remaining sludge will be the basis for a fish feed. I say “basis” because I will be adding algae, maggots and molasses (imported cheap from Fiji) to the sludge-feed. The algae is grown in the waste water from fish tanks as compared to fish ponds. A grant from FAO has been approved to further this work.
