Vegetable and fish — all in together
Story essay by Russ Grayson, June 2014
AQUAPONICS — it’s way to grow vegetables and fish together, without soil here at the Randwick Organic Community Garden.
Aquaponics is a closed-loop system of hydroponic food production in which water is pumped through vegetable growing containers, through a tank holding edible fish and back through the growing containers.
The water makes waste from the fish tank available as it irrigates the vegetables and delivers waste nutrients from the growing containers to the fish. Supplementary feed is usually provided to the fish to ensure a nutritionally balanced diet.
