Microponics

Last updated

Microponics, in agricultural practice, is a symbiotic integration of fish, plants, and micro-livestock within a semi-controlled environment, designed to enhance soil fertility and crop productivity. Coined by Gary Donaldson, an Australian urban farmer, in 2008, the term was used to describe his innovative concept of integrated backyard food production. It is important to note that while "microponics" had been previously used to refer to an obscure grafting method in hydroponics, Donaldson's application of the term was derived from the amalgamation of micro-livestock (micro-farming) and the cultivation of fish and plants, a practice commonly known as aquaponics.

History

The origins of microponics can be traced back to the integrated aquaculture experiments conducted by the New Alchemy Institute during the late 1960s and early 1970s. The New Alchemists developed innovative food production models that revolved around the integration of various elements, including fish, plants, ducks, rabbits, and other organisms, all housed within their solar and wind-powered Cape Cod Ark bio-shelter. [1]

The concept of integrated aquaculture, which involves converting the by-products (waste) of one species into the feedstock (food, fertilizer, etc.) for another species, deeply resonated with Gary Donaldson when he was introduced to it in the mid-1970s. His vision was to create a backyard food production system that empowered ordinary households to cultivate their own fresh and clean food using modest skills and appropriate technology. Recognizing that water was a fundamental necessity for all plant and animal species, Donaldson believed that aquaculture should play a central role in any integrated backyard food production system.

While inspired by the idea of integration from the New Alchemists, Donaldson faced a challenge regarding scale. The Cape Cod Ark, which measured just under 30 meters in length and 6 meters in height, proved to be too large for an average backyard setting.

Furthermore, in the 1970s, the translation of the New Alchemists' work into an Australian context was hindered by the lack of information about the culture of Australian fish species. However, in the following two decades, aquaculture in Australia matured, and local researchers identified several suitable freshwater aquaculture species. By 2007, Gary Donaldson became confident that limited quantities of Australian freshwater fish could be successfully grown in as little as 600 liters of water in a backyard environment.

The concept of integrated aquaculture served as a precursor to aquaponics, which gained international momentum by the mid-2000s. While aquaponics is typically defined as the combination of recirculating aquaculture and hydroponics to produce fish and plants, Donaldson found this concept to be limiting. He continued to advocate for a more holistic approach to small-scale food production, incorporating the integration of micro-livestock. Microponics, as a concept, suggests that recirculating aquaculture can be advantageously combined with almost any plant growing system. One of the key issues with aquaponics, similar to many aquaculture practices, is its reliance on fishmeal and oil derived from wild catch marine species. The inherent greater bio-diversity in microponics offers the potential to reduce or even eliminate this dependency.

Integrations within microponics

The integrations embodied within microponics include:

Given its emphasis on backyard food production, microponics tends to focus on smaller micro-livestock species but, where space and local planning laws permit, the concept can be expanded to include traditional species such as pigs, goats, sheep, and even micro-cattle breeds like the Dexter.

Aquaculture, also known as aquafarming, is the controlled cultivation ("farming") of aquatic organisms such as fish, crustaceans, mollusks, algae and other organisms of value such as aquatic plants. Aquaculture involves cultivating freshwater, brackish water and saltwater populations under controlled or semi-natural conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish. Mariculture, commonly known as marine farming, is aquaculture in seawater habitats and lagoons, as opposed to freshwater aquaculture. Pisciculture is a type of aquaculture that consists of fish farming to obtain fish products as food.

<span class="mw-page-title-main">Mariculture</span> Cultivation of marine organisms in the open ocean

Mariculture, sometimes called marine farming or marine aquaculture is a specialized branch of aquaculture involving the cultivation of marine organisms for food and other animal products, in enclosed sections of the open ocean, fish farms built on littoral waters, or in artificial tanks, ponds or raceways which are filled with seawater. An example of the latter is the farming of marine fish, including finfish and shellfish like prawns, or oysters and seaweed in saltwater ponds. Non-food products produced by mariculture include: fish meal, nutrient agar, jewellery, and cosmetics.

Fish farming or pisciculture involves commercial breeding of fish, most often for food, in fish tanks or artificial enclosures such as fish ponds. It is a particular type of aquaculture, which is the controlled cultivation and harvesting of aquatic animals such as fish, crustaceans, molluscs and so on, in natural or pseudo-natural environments. A facility that releases juvenile fish into the wild for recreational fishing or to supplement a species' natural numbers is generally referred to as a fish hatchery. Worldwide, the most important fish species produced in fish farming are carp, catfish, salmon and tilapia.

Organic aquaculture is a holistic method for farming fish and other marine species in line with organic principles. The ideals of this practice established sustainable marine environments with consideration for naturally occurring ecosystems, use of pesticides, and the treatment of aquatic life. Managing aquaculture organically has become more popular since consumers are concerned about the harmful impacts of aquaculture on themselves and the environment.

<span class="mw-page-title-main">Aquaculture in Canada</span>

Aquaculture is the farming of fish, shellfish or aquatic plants in either fresh or saltwater, or both. The farmed animals or plants are cared for under a controlled environment to ensure optimum growth, success and profit. When they have reached an appropriate size, they are harvested, processed, and shipped to markets to be sold. Aquaculture is practiced all over the world and is extremely popular in countries such as China, where population is high and fish is a staple part of their everyday diet.

Saltwater aquaponics is a combination of plant cultivation and fish rearing, systems with similarities to standard aquaponics, except that it uses saltwater instead of the more commonly used freshwater. In some instances, this may be diluted saltwater. The concept is being researched as a sustainable way to eliminate the stresses that are put on local environments by conventional fish farming practices who expel wastewater into the coastal zones, all while creating complementary crops.

The Integrated Floating Cage Aquageoponics System (IFCAS) was developed as an aquaculture-horticulture based on the concept of integrated farming system approach firstly in Bangladesh in 2013 to produce fish and vegetables in floating condition where waste materials (fish feces and unused feed) from fish culture dissolved in the pond water and settled on the bottom mud are used for vegetables production. Of the newly adopted term aquageoponics, aqua, geo and ponics means water, mud/soil and cultivation, respectively. In fact, aquageoponics is a new version of traditional aquaponics where soil is used as a medium instead of conventional media such as hydroton, pebbles, and sponges.

<span class="mw-page-title-main">Recirculating aquaculture system</span> Fish farming method

Recirculating aquaculture systems (RAS) are used in home aquaria and for fish production where water exchange is limited and the use of biofiltration is required to reduce ammonia toxicity. Other types of filtration and environmental control are often also necessary to maintain clean water and provide a suitable habitat for fish. The main benefit of RAS is the ability to reduce the need for fresh, clean water while still maintaining a healthy environment for fish. To be operated economically commercial RAS must have high fish stocking densities, and many researchers are currently conducting studies to determine if RAS is a viable form of intensive aquaculture.

Urban aquaculture is the aquatic farming of organisms, including all types of fish, cuttlefish, mussel shrimp and aqua plants within the urban environment. In essence, urban aquaculture is the practice of aquaculture in an urban, or urbanising, environment. Urban aquaculture systems can be associated with a multitude of different production locations, species used, environment, and production intensity. The use of urban aquaculture has increased over the last several years as societies continue to urbanise and demand for food in urban environments increases. Methods of production include recirculating systems; land-based culture systems; multifunctional wetlands; ponds, borrow pits and lakes; cages and culture-based fisheries. Most production in urban environments will include either extensive or intensive, compared to aquaculture in general which is normally semi-intensive.
