CAN (PE): A man's passion for aquaponics

Dave Atkinson with CBC is working on a new series for CBC P.E.I. called "The Things We Do For Love." In this series, he wants to tell stories of the things people do because they bring them joy. The most recent story in this series is about a man and his love for aquaponics.

Colin MacLean, a reporter at the Journal Pioneer in Summerside, spends his free time working on a small aquaponics installation in a little room inside a warehouse. Along one wall are two big bins overflowing with lush tomato plants. Right beside them is a tank filled with water.

The fish tank is connected by PVC pipe to a series of pumps and reservoirs to the big bins growing tomato plants. "Aquaponics is an amalgamation of hydroponics — which is growing plants entirely in water, with some nutrients added in — and aquaculture, which is obviously growing fish."

The water in the fish tank gets dirty with waste. That water is pumped into the grow beds, where bacteria converts the fish by-product into nitrates. The plants suck up the nitrates and clean the water, which is pumped back to the fish tank.
