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, refers specifically to aquaculture practiced in seawater habitats and lagoons, opposed to in freshwater aquaculture. Pisciculture is a type of aquaculture that consists of fish farming to obtain fish products as food.
Hydroponics is a type of horticulture and a subset of hydroculture which involves growing plants, usually crops or medicinal plants, without soil, by using water-based mineral nutrient solutions in aqueous solvents. Terrestrial or aquatic plants may grow with their roots exposed to the nutritious liquid or in addition, the roots may be mechanically supported by an inert medium such as perlite, gravel, or other substrates.
Mariculture or marine farming 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.
The following outline is provided as an overview of and topical guide to sustainable agriculture:
Aquaponics is a food production system that couples aquaculture with hydroponics whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants.
Aeroponics is the process of growing plants in the air or mist environment without soil or an aggregate medium. The word "aeroponic" is derived from the Greek meanings of aer ("air") and ponos ("labour"). It is a subset of hydroponics, since water is used in aeroponics to transmit nutrients.
The National Organic Program (NOP) is the federal regulatory framework in the United States of America governing organic food. It is also the name of the United States Department of Agriculture (USDA) Agricultural Marketing Service (AMS) program responsible for administering and enforcing the regulatory framework. The core mission of the NOP is to protect the integrity of the USDA organic seal. The seal is used for products adhering to USDA standards that contain at least 95% organic ingredients.
Vertical farming is the practice of growing crops in vertically stacked layers. It often incorporates controlled-environment agriculture, which aims to optimize plant growth, and soilless farming techniques such as hydroponics, aquaponics, and aeroponics. Some common choices of structures to house vertical farming systems include buildings, shipping containers, tunnels, and abandoned mine shafts. As of 2020, there is the equivalent of about 30 ha of operational vertical farmland in the world.
The Science Barge is a floating urban farm and environmental education center that has been docked in Yonkers, New York, USA since late 2008. The Barge grows crops using a hydroponic greenhouse powered by solar panels, wind turbines, and biofuels. The crops in the greenhouse are irrigated by captured rainwater and desalinated river water. Food is grown without carbon emissions, no agricultural waste is discharged into the watershed and no pesticides are used. The Science Barge is also a public education tool and hosts school groups from Westchester, New York City and the greater New York area visiting during the week, and the general public on weekends. From 2006–2008, the Science Barge docked for periods of two months at each of six stops along the Manhattan waterfront with the goal of educating the public on urban sustainable agriculture.
Maurice A. Ferré Park is a 30-acre (0.12 km2) public, urban park in downtown Miami, Florida. The park opened in 1976 on the site of several slips served by the Seaboard Air Line Railroad. It was originally named "Bicentennial Park" to celebrate the bicentennial of the United States in that same year. Today, the park is maintained by the Bayfront Park Management Trust. The park is bordered on the north by I-395, Metromover, and the former Miami Herald headquarters, on the south by the American Airlines Arena and Bayside Marketplace, on the west by Biscayne Boulevard and on the east by Biscayne Bay.
Microponics is the symbiotic integration of fish, plants, and micro-livestock in a semi-controlled environment. The term was adopted by Australian urban farmer, Gary Donaldson, in 2008, 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 the production of fish and plants - aquaponics.
Building-integrated agriculture (BIA) is the practice of locating high-performance hydroponic greenhouse farming systems on and in mixed-use buildings to exploit synergies between the built environment and agriculture.
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.
Fish Meat is a 2012 documentary by Fish Navy Films that analyzes and questions current fish farming practices. It was an official selection at the Blue Ocean Film Festival, Idyllwild Film Festival, San Francisco Ocean Film Festival, Catalina Film Festival and. It has also screened around the country, including at the University of Colorado and at University of Massachusetts Amherst. The documentary examines different methods used in modern aquaculture from Atlantic bluefin tuna ocean pens, to trout closed system farms, to old fashioned carp farms and concludes that the fish from lower in the food chain is better for sustainable aquaculture.
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.
Theodore "Ted" Caplow is an American social entrepreneur, environmental engineer, and inventor. He is co-founder of AgTech disruptor BrightFarms and a pioneer in the field of sustainable agriculture, having designed and developed both the Science Barge in Yonkers, New York (NY) and the Miami Science Barge, urban farming prototypes that address vegetable and fish production, respectively. Caplow has also patented a Vertically Integrated Greenhouse. He has founded or co-founded five companies in the area of applied science and sustainable technology: NY Sun Works (2004), BrightFarms (2008), Fish Navy Films (2010), CappSci (2014), and Caplow|Manzano (2017), which Caplow created with frequent collaborator Nathalie Manzano to pursue design consulting and development opportunities in sustainable real estate, ecological technology, and long-term risk management. As an academic, Caplow has published a series of peer-reviewed articles on water contaminant dynamics in the Hudson River Estuary.
Vermiponics is a soil-less growing technique that combines hydroponics with vermiculture by utilizing diluted wormbin leachate as the nutrient solution as opposed to the use of fish waste or the addition of manufactured chemicals to provide the nutrients.
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.
The Sustainable Technology Optimization Research Center (STORC) is a research facility located on the California State University Sacramento campus.

The STORC Vision is to become "an international resource for practical, scalable, and financially viable solutions in the area of sustainable technologies that are suitable for private and/or public sector operations related to the management of energy, food, water, and waste". The STORC Mission is "to demonstrate the operation of innovative commercially viable physical systems that are underpinned by sustainable technologies, and to disseminate the associated plans, public policy discourse, and scientific findings".
Anthroponics is a type of hydroponics system that uses human waste like urine as the source of nutrients for the cultivated plants. In general, the human urine or mixed waste is collected and stored for a period of time, before being applied either directly or passed through a biofilter before reaching the plants. As a form of organic hydroponics, anthroponics combines elements of both hydroponics and aquaponics systems.
