What is this aquaponics you speak of...
Aquaponics is the integration of tank-based fish culture with hydroponic (aquatic) plant production. In fish-only aquaculture, the fish are fed and produce waste in the water. In aquaponics, the nutrient-rich water the fish produce is considered a commodity instead of a waste, and is used to supply a large proportion of the nutrients required to grow the plants. Therefore, the fish feed and produce wastes and these wastes are then used as a feed (nutrient) source for the plants. Once the plants have utilised the nutrients and cleaned them out of the water, the water is returned to the fish for further fish culture, and the perpetual cycle begins again.
A NATURAL FARMING METHOD
Because the plants and fish share the water resource there is no possibility to use pesticides or herbicides because these chemicals would kill the fish. This means aquaponics has its own in-built pesticide and herbicide, non-application control mechanism, which ultimately means the produce is guaranteed to be safer.
PERFECT FOR INNER CITIES
Because of their compact nature, aquaponic facilities may be located very close to the end users (restaurants, green grocers, food manufacturers) in a variety of locations (country, city). This means the saved land resources may be used to increase biodiversity via returning the land to natural ecologies that enhance the global natural ecosystem.
ZERO ENVIRONMENTAL IMPACT
No nutrient-rich waste-water or fish wastes are discharged to the environment with aquaponics. In normal aquaculture, all the fish wastes are released to the environment in some form that can cause negative environmental impacts.
HIGH DENSITY & PRODUCTION
Aquaponics is one of only a few farming systems that allows the high density and high production requirements needed to make urban farming possible and economically viable. It may also be practiced in any area because it does not rely on soil. This means that anyone can practice aquaponics and anyone can locate it anywhere they wish to, thus opening up the ability to farm to almost anyone in the world.
