Understanding Aquaponics
1. Zero waste system beginning with food waste from cafeteria to feed black soldier fly larvae
2. Black soldier fly larvae to feed fish and produce leachate to feed plants in garden
3. The role of fish: production of ammonia to feed bacteria called nitrosonomas
4. The role of bacteria nitrosomonas to feed on ammonia, waste becomes nitrites
and feeds bacteria called nitrobacter
5. the role of bacteria nitrobacter is to feed on nitrites, waste becomes nitrates
6. The role of plants: consumers of nitrates to purify water for fish
