![]() Instead of soil, various inert growing media, also called substrates, are used. Taking a look at a transcript from a FAO report, they speak of soil-less cultures as a way of growing agricultural crops without the use of soil. There are other ways of growing food rather than directly from the soil. The four major categories of aquaculture include open water systems (e.g.cages, longlines), pond culture, flow-through raceways, and recirculating aquaculture systems (RAS). Aquaculture production methods have been developed in various regions of the planet, and have thus been adjusted to the distinct environmental and climatic conditions in different regions. Many aquatic species have been cultured, especially fish, crustaceans and mollusks and aquatic plants and algae. Moreover, the FAO also describes aquaculture as the captive rearing and production of fish and other aquatic animal and plant species under controlled conditions. There are two main types of aquaculture-marine and freshwater. Aquaculture is a method used to produce food and other commercial products, restore habitat and replenish wild stocks, and rebuild populations of threatened and endangered species.

In other words, according to the Aquaponics Gardening Community, cited by Thorarinsdottir, aquaponics is the cultivation of fish and plants together in a constructed, recirculating ecosystem utilizing natural bacterial cycles to convert fish waste to plant nutrition. and they can be either freshwater systems or contain salt or brackish water. Can aquaponics be part of the agricultural solution? What is the aquaponics system and how different is it from hydroponics? What are the benefits of aquaponics? What Is Aquaponics? Simple DefinitionĪccording to a joint report from the Food And Agriculture Organization and SmartFish, aquaponics is the cultivation of plants and aquatic animals in a recirculating environment.Īquaponics is a cooperation between plants and fish and the term originates from the two words aquaculture (the growing of fish in a closed environment) and hydroponics (the growing of plants usually in a soil-less environment).Īquaponic systems come in various sizes from small indoor units to large commercial units. Agriculture depends largely on artificial chemicals, whose sourcing can be expensive and polluting, to produce food. Modern agriculture, forestry, and other land uses are accountable for 25% of GHG emissions.
