Microponics

Microaquaponics is the symbiotic integration of fish, plants and micro-livestock in a semi-controlled environment. The term was created recently by Australian urban farmer, Gary Donaldson to describe his integrated backyard food production concept. While microponics was also the name given to an obscure grafting method used in hydroponics, Donaldson's use of the term was derived from the integration of micro-livestock (and micro-farming) and the production of fish and plants - aquaponics.
==History==
Microponics has its roots in the integrated aquaculture work undertaken by the New Alchemy Institute during the late 1960s and early 1970s. The New Alchemists had developed useful food production models based on the integration of fish, plants, ducks, rabbits and other organisms - all of which were housed in their solar and wind-powered Cape Cod Ark bio-shelter.〔Wm McLarney and John Todd (1974). "Walton Two: A Compleat Guide to Backyard Fish Farming", ''The Journal of the New Alchemists No. 2'', pp 79-115 (Green Center )〕
Integrated aquaculture, in which the by-products (waste) of one species are converted to become the feedstock (food, fertilizer, etc.) of another species, struck an immediate chord with Donaldson when he was first introduced to it in the mid-1970s. His goal was to develop a backyard food production regime that would enable the average householder to grow their own clean fresh food through the application of modest skills and appropriate technology. He reasoned that the one thing that all plant and animal species had in common was a need for water so it seemed logical that aquaculture should become a cornerstone of any integrated backyard food production system.
Once the New Alchemists had reconnected him with the notion of integration (which is largely traditional mixed farming with an appropriate technology twist), Donaldson still grappled with the issue of scale. At just under 30 metres long and 6 metres high, the Ark was rather too large for the average backyard.
Notwithstanding the innovative approach of the New Alchemists, translation of their work into an Australian context back in the 1970s was also hindered by the lack of information about the culture of Australian fish species. In the ensuing twenty years, aquaculture in Australia came of age and local researchers identified a number of suitable freshwater aquaculture species. Since 2007, Gary Donaldson has satisfied himself that limited quantities (in a backyard context) of Australian freshwater fish could be successfully grown out in as little as 600 litres of water.
Integrated aquaculture was also the precursor to aquaponics (the integration of recirculating aquaculture and hydroponics) which, by the mid-2000s, was beginning to gain international momentum. Gary Donaldson found the notion of aquaponics too limiting and he continued to promote a more holistic approach to small-scale food production through the inclusion of micro-livestock. Aquaponics is, by definition, the combination of recirculating aquaculture and hydroponics for the production of fish and plants, however, microponics suggests that recirculating aquaculture can be advantageously integrated with virtually any plant growing system. The principal issue surrounding aquaponics is (like most aquaculture) its reliance on fishmeal and oil from wild catch marine species. The greater bio-diversity inherent in microponics offers the opportunity to reduce or even eliminate this dependency.
