Interest in Aquaponics, a food production system in which plants are grown in fresh water and obtain nutrition from waste material produced by fish living in the water, is rapidly increasing. The reason, according to aquaponics pioneer Charles Shultz, is that aquaponics produces both meat and vegetables using an all-natural self contained system requiring little outside water or fertilizers. Recent widespread drought and fresh water shortages have motivated many food producers to look more closely at the potential of aquaponics.

Schultz was interviewed on the Sharon Kleyne Hour™ Power of Water® radio show of January 5, 2015. For the live broadcast, or podcasts of past shows, go to http://www.voiceamerica.com/show/2207/the-sharon-kleyne-hour. Coincidentally, a commercially manufactured aquaponic system designed for home marijuana production, was announced a few days after the Schultz interview.*

Charles Schultz has traveled the world lecturing on aquaponic food production systems, both small and large scale. He is considered the world's leading authority on aquaponics. Schultz was based at the University of the Virgin Islands for 14 years but is now at the University of Lethbridge in Alberta, Canada.

The syndicated Sharon Kleyne Hour™ Power of Water® radio show, hosted by fresh water advocate Sharon Kleyne, is heard weekly on VoiceAmerica and Apple iTunes. The education oriented show is sponsored by Bio-Logic Aqua® Research, a global research and technology center founded by Kleyne and specializing in fresh water, the atmosphere and dehydration. Nature's Tears® EyeMist® is the Research Center's signature product for dry and dehydrated eyes.

The difference between aquaponics and the more common hydroponics, according to Schultz, is that hydroponics grows vegetables in fresh water using fertilizer to feed the plans. Aquaponics combines aquaculture, the commercial growing of fish, with hydroponics, producing both fish and vegetables. The plants feed off the fish's waste material, which purifies and recyces the water so that it can be constantly reused. The fish can be harvested or not harvested but do require fish food.

Food grown indoors with an aquaponic system, according to Kleyne, would be more nutritious than food grown outdoors in the soil because there is no pollution and the environment is controlled. Adjusting the environment can make output even more nutritious or grow faster.

The most commonly utilized fish is tilapia, says Schultz, a warm water lake and river species that ranks number one with salmon in commercial production. Tilapia are hardy, feed only on plant material and produce lots of waste. Where the fish aren't harvested, koi goldfish, another warm water herbivorous fish that produces copious amounts of waste, are often substituted. Koi grow much larger than tilapia

Because koi and tilapia are warm water fish, according to Schultz, aquaponics is best suited for tropical for subtropical vegetables and herbs. Lettuce also grows well.

Schultz became a leading global authority on aquaponics while at the University of the Virgin Islands on St Croix. Because St. Croix has no rivers, very little ground water, extremely variable rainfall and large arid areas, according to Schultz, nearly all the island's fresh water comes from rainwater. Aquaponics has enabled St. Croix to grow its own food without requiring large amounts of water.

When Schultz moved to Alberta's University of Leftbridge, he was faced with numerous challenges. Replicating the St. Croix system would require greenhouses and a large expenditure on heating. Schultz has is experimenting with alternate fish and plant species not requiring quite so much heat.

One interesting aspect of aquaponics, Schultz and Kleyne agree, is its scalability. It can be done inexpensively in an apartment or in a restaurant desiring to grow its own fish and/or exotic vegetables. The system is can also be suitable for large scale commercial operations. Aquaponics is becoming popular in Australia, which has few rivers and large desert regions.

Kleyne supports aquaponic s because it is all natural, economical and solves a number of problems with no adverse side effects or large consumption of resources. Life on Earth, Kleyne explains, depends on the natural recycling of water. The more closely we replicate nature, the better off we will be. In nature, few environmental niches go unfilled. In aquaponics, there are no unfilled niches.
