Nourishing the Planet’s Kimberlee Davies spoke recently with Matt Ray, the principal farmer for Sweet Water Organics, an aquaponics training organization in Milwaukee, about his experience in the field of aquaponics.
What is aquaponics? How did you become involved?
Aquaponics has been around for centuries. It was traditionally a technique in tropical climates, using floating bamboo rafts with vegetation in fresh water pools. This was simply the adaptation of agriculture to the tropics. The technique has become cutting edge over the last 20 years. We can adapt aquaponics to today’s geographies and culture.
Aquaponics is a blending of aquaculture (the raising of aquatic animals) and hydroponics (growing plants in water without soil). In aquaponics, aquatic animals serve as the nutrition base for the plants. The great thing about aquaponics is that it is a closed system; it doesn’t have to flow in one pipe and out of another.
I saw it begin to pop up in the late 1980s, starting with the Virgin Islands, Australia, and even Asia, where fish are grown symbiotically with rice paddies. Forward-thinking farmers and activists began to develop the practice in non-tropical climates, and academics began researching the field. Twenty years later, we have a lot more people doing it. Scientific data has emerged to support the spread and success of this technique. It’s possible to take the nuts and bolts and adapt them to wherever you are. It’s going to work and it can be replicated.
