Aquaponics a Sustainable Food Alternative
May 16th, 2011 by Glenn Meyers
With food prices rising and access to water and land limited in many parts of the world, many are looking at food production alternatives, one of them called aquaponics.
While the term, aquaponics, may sound alien, the practice is beginning to grab the attention of many who see it as one sustainable agricultural solution for an increasingly crowded planet. This is especially true for poverty stricken countries.
Georgia author Bevan Suits has written an attractive and informative e-book about the topic, “The Aquaponics Guidebook, Access to Personal Agriculture.” This book opens the world of aquaponics in a practical way, says Suits, “so you can learn about it quickly and get started, no matter your experience, budget or available space. Even beginners on a small scale will see amazing results. Greens like lettuce or basil can grow to harvest in four weeks.”
Colorado aquaponics pioneer Wayne Dorband, founder of World Wide Aquaculture, grows harvests vegetables, herbs and fish in the many testing tanks he has established in the low light settings at his company warehouse in Loveland, Colorado. He points out that this method of growing food is innovative, inexpensive, pleasant to look at, and sustainable. Both he and Suits believe families can use these compact systems worldwide, producing fish and vegetables to feed individuals on an ongoing basis.
A viable aquaponics system combines traditional agriculture and aquaculture methods without soil. In short order the system produces a healthy culture for fish, herbs, fruits, vegetables and ornamentals to thrive. The only additional material required is water. Fish are fed some of the plants growing in the system, and their waste fertilizes the plants.
“There is no need for additional fertilizer, weed killers or outside food if the system is properly designed,” says Dorband, pulling a trout filet from his freezer that required four months to mature.
According to Dorband, the simplest of Mountain Sky’s aquaponics system can be purchased and installed for less than $100. The components used in Dorband’s aquaponics systems come from recycled materials such as 55-gallon drums otherwise destined for landfills, PVC pipes, pumps and washed gravel. No special water is required, as the plants purify local, well, or pond water.
In this You Tube video, Travis Hughey, founder of Barrel-Ponics, features a system where plants grow without soil, fed by fish waste, and where fish feed on water plants for nutrition. This three-minute video, although somewhat arduous, shows how the system works and is worth the time.
