Aquaponics is a bio-integrated system that links recirculating aquaculture with hydroponic vegetable, flower, and/or herb production. Recent advances by researchers and growers alike have turned aquaponics into a working model of sustainable food production. This publication provides an introduction to aquaponics with brief profiles of working units around the country. An extensive list of resources points the reader to print and Web-based educational materials for further technical assistance.
Aquaponics, also known as the integration of hydroponics with aquaculture, is gaining increased attention as a bio-integrated food production system.
Aquaponics serves as a model of sustainable food production by following certain principles:
In aquaponics, nutrient-rich effluent from fish tanks is used to fertigate hydroponic production beds. This is good for the fish because plant roots and rhizobacteria remove nutrients from the water. These nutrients — generated from fish manure, algae, and decomposing fish feed — are contaminants that would otherwise build up to toxic levels in the fish tanks, but instead serve as liquid fertilizer to hydroponically grown plants. In turn, the hydroponic beds function as a biofilter — stripping off ammonia, nitrates, nitrites, and phosphorus — so the freshly cleansed water can then be recirculated back into the fish tanks. The nitrifying bacteria living in the gravel and in association with the plant roots play a critical role in nutrient cycling; without these microorganisms the whole system would stop functioning.
Greenhouse growers and farmers are taking note of aquaponics for several reasons:
The technology associated with aquaponics is complex. It requires the ability to simultaneously manage the production and marketing of two different agricultural products. Until the 1980s, most attempts at integrated hydroponics and aquaculture had limited success. However, innovations since the 1980s have transformed aquaponics technology into a viable system of food production. Modern aquaponic systems can be highly successful, but they require intensive management and they have special considerations.
This publication provides an introduction to aquaponics, it profiles successful aquaponic greenhouses, and it provides extensive resources. It does not attempt to describe production methods in comprehensive technical detail, but it does provide a summary of key elements and considerations.

Aquaculture Enterprises: Considerations and Strategies
Agricultural Business Planning Templates and Resources
A successful aquaponics enterprise requires special training, skills, and management. The following items point to key elements and considerations to help prospective growers evaluate the integration of hydroponics with aquaculture.
Hydroponics: Hydroponics is the production of plants in a soilless medium whereby all of the nutrients supplied to the crop are dissolved in water. Liquid hydroponic systems employ the nutrient film technique (NFT), floating rafts, and noncirculating water culture. Aggregate hydroponic systems employ inert, organic, and mixed media contained in bag, trough, trench, pipe, or bench setups. Aggregate media used in these systems include perlite, vermiculite, gravel, sand, expanded clay, peat, and sawdust. Normally, hydroponic plants are fertigated (soluble fertilizers injected into irrigation water) on a periodical cycle to maintain moist roots and provide a constant supply of nutrients. These hydroponic nutrients are usually derived from synthetic commercial fertilizers, such as calcium nitrate, that are highly soluble in water. However, hydro-organics — based on soluble organic fertilizers such as fish hydrosylate — is an emerging practice. Hydroponic recipes are based on chemical formulations that deliver precise concentrations of mineral elements. The controlled delivery of nutrients, water, and environmental modifications under greenhouse conditions is a major reason why hydroponics is so successful.
Nutrients in Aquaculture Effluent: Greenhouse growers normally control the delivery of precise quantities of mineral elements to hydroponic plants. However, in aquaponics, nutrients are delivered via aquacultural effluent. Fish effluent contains sufficient levels of ammonia, nitrate, nitrite, phosphorus, potassium, and other secondary and micronutrients to produce hydroponic plants. Naturally, some plant species are better adapted to this system than others. The technical literature on aquaponics provides greater detail on hydroponic nutrient delivery; especially see papers cited in the Bibliography by James Rakocy, Ph.D.
Plants Adapted to Aquaponics: The selection of plant species adapted to hydroponic culture in aquaponic greenhouses is related to stocking density of fish tanks and subsequent nutrient concentration of aquacultural effluent. Lettuce, herbs, and specialty greens (spinach, chives, basil, and watercress) have low to medium nutritional requirements and are well adapted to aquaponic systems.
Plants yielding fruit (tomatoes, bell peppers, and cucumbers) have a higher nutritional demand and perform better in a heavily stocked, well established aquaponic system. Greenhouse varieties of tomatoes are better adapted to low light, high humidity conditions in greenhouses than field varieties.
Fish Species: Several warm-water and cold-water fish species are adapted to recirculating aquaculture systems, including tilapia, trout, perch, Arctic char, and bass. However, most commercial aquaponic systems in North America are based on tilapia. Tilapia is a warm-water species that grows well in a recirculating tank culture. Furthermore, tilapia is tolerant of fluctuating water conditions such as pH, temperature, oxygen, and dissolved solids. Tilapia produces a white-fleshed meat suitable to local and wholesale markets. The literature on tilapia contains extensive technical documentation and cultural procedures. Barramundi and Murray cod fish species are raised in recirculating aquaponic systems in Australia.
Water Quality Characteristics: Fish raised in recirculating tank culture require good water quality conditions. Water quality testing kits from aquacultural supply companies are fundamental. Critical water quality parameters include dissolved oxygen, carbon dioxide, ammonia, nitrate, nitrite, pH, chlorine, and other characteristics. The stocking density of fish, growth rate of fish, feeding rate and volume, and related environmental fluctuations can elicit rapid changes in water quality; constant and vigilant water quality monitoring is essential.
Biofiltration and Suspended Solids: Aquaculture effluent contains nutrients, dissolved solids, and waste byproducts. Some aquaponic systems are designed with intermediate filters and cartridges to collect suspended solids in fish effluent, and to facilitate conversion of ammonia and other waste products to forms more available to plants prior to delivery to hydroponic vegetable beds. Other systems deliver fish effluent directly to gravel-cultured hydroponic vegetable beds. The gravel functions as a "fluidized bed bioreactor," removing dissolved solids and providing habitat for nitrifying bacteria involved in nutrient conversions. The design manuals and technical documentation available in the Resources section can help growers decide which system is most appropriate.
Component Ratio: Matching the volume of fish tank water to volume of hydroponic media is known as component ratio. Early aquaponics systems were based on a ratio of 1:1, but 1:2 is now common and tank: bed ratios as high as 1:4 are employed. The variation in range depends on type of hydroponic system (gravel vs. raft), fish species, fish density, feeding rate, plant species, etc. For example, the Speraneo system described below is designed for one cubic foot of water to two cubic feet of grow bed media (pea gravel). Further, when shallow bed systems only three inches in depth are employed for the production of specialty greens such as lettuce and basil, the square footage of grow space will increase four times. Depending on the system design, the component ratio can favor greater outputs of either hydroponic produce or fish protein. A "node" is a configuration that links one fish tank to a certain number of hydroponic beds. Thus, one greenhouse may contain a multiple number of fish tanks and associated growing beds, each arranged in a separate node.
Profiles of several aquaponic greenhouses are highlighted below as models of commercially viable systems. Most of these operations are featured in magazine articles and conference proceedings. Some operations off er technical assistance through short courses, design manuals, and on-site tours. Please refer to articles in the Resources section, and the Bibliography, for in-depth descriptions and technical details.
Water consumption in an integrated aqua-vegeculture system amounts to 1 percent of that required in pond culture to produce equivalent tilapia yields. In the 1980s Mark McMurtry (former graduate student) and the late Doug Sanders (professor) at North Carolina State University developed an aqua-vegeculture system based on tilapia fish tanks sunk below the greenhouse floor. Effluent from the fish tanks was trickle-irrigated onto sand-cultured hydroponic vegetable beds located at ground level. The nutrients in the irrigation water fed tomato and cucumber crops, and the sand beds and plant roots functioned as a biofilter. After draining from the beds, the water recirculated back into the fish tanks. The only fertility input to the system was fish feed (32 percent protein).
Some findings and highlight s of McMurtry's research:
See the Bibliography on Aquaponics in the appendix for a of list articles that resulted from the North Carolina research.
Aqua-vegeculture research at NCSU has been discontinued because the technology had evolved to the point where it is ready for grower application. The Department of Horticulture and the Cooperative Extension Service at NCSU provide technical assistance to aquaponic greenhouse growers in North Carolina.
In the early 1990s, Tom and Paula Speraneo — owners of S & S Aqua Farm near West Plains, Missouri — modified the North Carolina State method by raising tilapia in a 500-gallon tank, with fish effluent linked to gravel-cultured hydroponic vegetable beds inside an attached solar greenhouse. Later, they expanded to a full-size commercial greenhouse. The Speraneo system was practical, productive, and wildly successful. It became the model for dozens of commercial aquaponic greenhouses and high school biology programs.
Sadly, Tom Speraneo died in February 2004. Tom was a true pioneer in aquaponics, and he was unfailingly generous and helpful to others. Paula Speraneo and her family continue to run the greenhouse and actively participate in aquaponics technology transfer. The following notes describe the Speraneo system and available resources.
The commercial-scale solar greenhouse at S & S Aqua Farm is 50 feet by 80 feet, oriented East-West to create a south-facing slope. It contains six 1,200 gallon fish tanks. Each tank is linked to six one-foot-deep hydroponic beds filled with river gravel. Tom referred to each tank-plus-hydroponic bed setup as a "node." This way, each node can operate independently of one another.
Some aspects of the Speraneo system were modeled after the aquaponics research at North Carolina State University, while others are modified. The Speraneos employ hydroponic vegetable beds as "fluidized bed reactors," but they use pea-grade river gravel instead of sand. Tilapia are raised in fish tanks, but the tanks are more conveniently located above ground and tilapia hybrids adapted to cooler water temperatures are grown. The reciprocating water cycle, PVC piping, and return-flow water pumping methods were designed by Tom and Paula to match their system.
For years, Purina® fish chow at 40 percent protein was the primary fertility input, supplemented with tank-cultured algae. Tilapia in the Speraneo system are raised for 7 to 12 months, then harvested at one to one-and-a-half pounds in size. Later, Tom started adding small amounts of Planters 2® rock dust on top of the gravel as a trace element supplement.
S & S Aqua Farm has grown fresh basil, tomatoes, cucumbers, mixed salad greens, and an assortment of vegetable, herb, and ornamental bedding plants in the aquaponic greenhouse. In the early 1990s, Tom and Paula were raising and selling basil for $12 a pound to gourmet restaurants about four hours away in St. Louis, Missouri. Following passage of the North American Free Trade Agreement (NAFTA), however, Mexican imports of basil resulted in a market crash to $4 per pound, so they dropped the St. Louis market. S & S Aqua Farm now grows a diverse variety of vegetable and herbs, selling locally at a farmers market combined with direct sales out of their greenhouse.
Tom once calculated the farm produces 45 to 70 pounds of produce for every pound of tilapia, an impressive yield. However, Paula explained this figure takes into account the cumulative yields of multiple vegetable crops raised during the 7- to 12-month time period required to raise fish to harvest.
The component ratio favors vegetables over fish yields in the Speraneo system.
Interest in the Speraneo system resulted in more than 10,000 visitors to the small farm in Missouri, including school children, farmers, researchers, and government officials. To handle requests for assistance, the Speraneos compiled a resource packet and design manual with technical specifications to establish an S & S Aqua Farm-style aquaponic system. The resource packet includes a 10-minute video and a list of supplies. Response from growers to a practical design manual such as this was tremendous. The Speraneo system is now in use worldwide. The resource packet is available through:

James Rakocy, Ph.D., and associates at the University of the Virgin Islands (UVI) developed a commercial-scale aquaponic system that has run continuously for more than five years. Nile and red tilapia are raised in fish rearing tanks, and the aquacultural effluent is linked to floating raft hydroponics. Basil, lettuce, okra, and other crops have been raised successfully, with outstanding quality and yields.
The system components include: Four fish rearing tanks at 7,800 liters each, clarifiers, filter and degassing tanks, air diffusers, sump, base addition tank, pipes and pumps, and six 400-square foot hydroponic troughs totaling 2,400 sq. ft. The pH is monitored daily and maintained at 7.0 to 7.5 by alternately adding calcium hydroxide and potassium hydroxide to the base addition tank, which buff ers the aquatic system and supplements calcium and potassium ions at the same time. The only other supplemental nutrient required is iron, which is added in a chelated form once every three weeks.
Tilapia are stocked at a rate of 77 fish per cubic meter for Nile tilapia, or 154 fish per cubic meter for red tilapia and cultured for 24 weeks. The production schedule is staggered so that one tank is harvested every six weeks. After harvest, the fish tank is immediately restocked. The fish are fed three times daily with a complete, floating fish pellet at 32 percent protein. Projected annual fish production is 4.16 metric tons for Nile tilapia and 4.78 metric tons for red tilapia.
In one notable experiment the UVI researchers compared the yields of a leafy herb (basil) and a fruiting vegetable (okra) grown in aquaponic vs. field production systems. Basil and okra were raised in raft hydroponics. Yields of aquaponic basil were three times greater than field-grown, while yields of aquaponic okra were 18 times greater than field-grown. Based on a market price in the U.S. Virgin Islands of $22 per kg for fresh basil with stems, researchers calculated gross income potential. The aquaponic method would result in $515 per cubic meter per year or $110,210 per system per year. This compares to field-produced basil at $172 per cubic meter per year or $36,808 per year for the same production area. When fish sales are included, the aquaponic system yields $134,245 (Rakocy, et al, 2004).
Like McMurtry, researcher Rakocy sees integrated water reuse systems as a viable solution to sustainable food production in developing countries and arid regions — such as the Caribbean Islands — where fresh water is scarce.
To provide in-depth technical support, the UVI research team off ers a week-long short course on aquaponics each year at the UVI agricultural experiment station. The UVI short course is the premier educational training program available to farmers in the world. In addition to aquaponics, UVI specializes in greenwater tank culture, a recirculating aquaculture system.
Rakocy has published extensive research reports and several Extension Service bulletins on recirculating aquaculture and aquaponics.

The Freshwater Institute System The Freshwater Institute in Shepherdstown, West Virginia — a program of The Conservation Fund, an environmental non-profit organization — specializes in aquaculture research and education. Fresh spring water is an abundant resource in the Appalachian region. However, protection of spring water quality as it relates to aquaculture effluent is viewed as a vital component of this technology.
For years, the institute has specialized in cold-water recirculating aquaculture systems raising trout and arctic char. The institute helps Appalachian farmers set up two types of aquaculture systems: (a) an indoor, high-tech recirculating tank method and (b) an outdoor, low-tech recirculating tank method. Treatment of aquaculture effluent prior to its return to the natural stream flow led to collaborative research with USDA-ARS scientists in Kearneysville, West Virginia, on integrated hydroponic-fish culture systems. Trials at the institute's greenhouses showed that nitrogen, phosphorus, and other nutrients in aquaculture effluent can be effectively removed by plants grown in NFT hydroponics or constructed wetland systems.
In the mid-1990s, the institute implemented an aquaponic demonstration program based on a Speraneo-style gravel-cultured system. Tilapia is raised as a warm-water fish species. Hydroponic crops include basil, lettuce, and wetland plants.
To provide technical assistance to farmers and high school biology teachers, the institute published a series of publications on recirculating aquaculture and aquaponics. The Freshwater Institute Natural Gas Powered Aquaponic System — Design Manual is a 37- page manual published by the institute in 1997. Included are diagrams and photos, details on greenhouse layout and aquaponic production, parts list with suppliers and cost, estimated operating expense, and further informational resources.
Please note the institute no longer provides direct technical assistance to farmers on aquaponics. Instead, it has made some of their publications on recirculating aquaculture and aquaponics available online.

Instead of locating the fish and vegetable components in separate containers inside a greenhouse, fish production can be located in outdoor tanks or adjacent buildings. The effluent simply needs to be delivered to hydroponic vegetable beds.
In warm climates, hydroponic vegetable beds may be located outside. As an example, the Center for Regenerative Studies at California State Polytechnic University — Pomona implemented an outdoor integrated bio-system that links: (a) a pond containing treated sewage wastewater stocked with tilapia and carp; (b) water hyacinth — an aquatic plant very efficient at sucking up nutrients — covering 50 percent of the water surface area; the plant biomass generated by water hyacinth is used as feedstock for compost heaps; (c) nearby vegetable gardens irrigated with nutrient-laden pond water.
In addition to locating the fish and vegetable components in separate containers, fish and plants can be placed in the same container to function as a polyculture. For example, plants sit on top of floating polystyrene panels with their roots hanging down into the water that fish swim around in. Models include the Rakocy system, solar-algae ponds (see literature by Zweig and Kleinholz), and the solar-aquatic ponds, or Living Machines, made popular by John Todd at Ocean Arks International.
In Australia, barramundi (Lates calcarifer) and Murray cod (Maccullochella peelii peelii) fish species have been adapted to recirculating aquaculture and aquaponics systems. The stocking densities for these fish species is higher than tilapia, which in turn results in greater hydroponic surface under production. Several references are provided on these fish species and aquaponic systems in the Resources and Bibliography sections.

Organic production of crops and livestock in the United States is regulated by the Department of Agriculture's National Organic Program, or NOP. The NOP is an organic certification and marketing program that ensures foods and food products labeled as "organic" meet universal standards and guidelines for organic production. Production inputs used in organic production — such as feed and fertilizers — must be of natural origin and free of synthetic materials. A farm plan, documentation of inputs and production methods, and farm inspection are required to obtain "certified organic" status. This process allows farm products to be labeled and sold as organic.
Organic trout, tilapia, salmon and other fish species are raised in Europe, Australia, and Israel using production standards developed by international organic certification agencies (for more information see The IFOAM Norms for Organic Production and Processing, Version 2005 and updated in 2009. However, organic aquaculture was not clearly defined in the NOP and the lack of organic aquaculture guidelines has hampered the growth of a domestic organic aquaculture industry in the United States.
The ATTRA publication Aquaculture Enterprises: Considerations and Strategies contains a section on organic aquaculture. It states that accredited organic certifying agencies can certify organic aquaculture operations, but the products are not allowed to carry the USDA organic label.
In fact, Quality Certification Services in Florida has certified three organic aquaculture operations in the U.S. and abroad under a private label. AquaRanch, an aquaponic greenhouse in Illinois, set a precedent for the aquaponics industry by obtaining organic certification for its hydroponic produce through Indiana Certified Organic. Meanwhile, AquaRanch markets its greenhouse-raised tilapia as "naturally grown."
To address the issue of organic aquaculture, the National Organic Standards Board (NOSB) established an Aquatic Animals Task Force in June 2000. In 2003, a second group — The National Organic Aquaculture Working Group (NOAWG), comprised of 80 aquaculture professionals and related stakeholders — formed to provide further guidance and clarification to the NOSB. The interim final report published by NOAWG in January 2006 provides proposed recommendations on organic aquaculture to NOSB.
To provide access to the large volume of documents, reports, and organic production standards surrounding the issue of organic aquaculture, the National Agricultural Library published an 80-page bibliography, Organic Aquaculture, through the Alternative Farming Systems Information Center.

Due to the highly technical nature of aquaponics and the expense associated with greenhouse production, prospective growers are advised to thoroughly investigate production methods and market potential.
For general information and supplies associated with greenhouse vegetable production, see the ATTRA resource list Greenhouse and Hydroponic Vegetable Production Resources on the Internet. Complementary ATTRA publications include Organic Greenhouse Vegetable Production and Integrated Pest Management for Greenhouse Crops.
Building and equipping a commercial-sized aquaponic greenhouse can cost $10,000 to $30,000, depending on the system design and choice of components. Due to the highly technical nature of aquaponics and the expense associated with greenhouse production, prospective growers are advised to thoroughly investigate production methods and market potential. A sequence of considerations and learning opportunities geared to evaluating an aquaponic greenhouse enterprise are listed below.

Sweet Water Organics will be the first major commercial upgrading of MacArthur genius Will Allen’s aquaculture methodologies, i.e. a three-tiered, aquaponic, bio-intensive fish-vegetable garden. Sweet Water will be the anchor project in the transformation of a massive industrial building in an “industrial slum” into a showcase of the potential of living technologies and high-value added urban agriculture. Sweet Water’s sustainable aquaculture system harvests urban waste streams, e.g. wood chips, cardboard, veggie residues, coffee grounds, and brewers mash, along vermiculture lines, yielding the richest possible soil. This soil in hundreds of potted plants on the simulated wetland tiers is key to the transformation of fish wastes into natural nitrate for plant growth and water filtration.

Bioshelters is a recirculating aquaponics facility located in Amherst, Massachusetts. Our entire system is contained in a large solar-heated greenhouse called a Bioshelter. Solar structures create the least expensive and best natural environment for plants, animals and people. To learn more about our greenhouse system please follow the link below. Because the fish, plant and human systems are linked, no pesticides can be used on our produce.
Much like community supported agriculture, community supported fisheries are cooperatives of family fishermen who market their catch directly to customers usually through a subscription mechanism, whereby customers receive a certain amount of product per week (a share) for a yearly share price. Four innovative projects are listed below:

The following bibliography contains selected literature citations on aquaponics and integrated hydroponics-aquaculture published in trade magazines and scientific journals. Collectively, these articles provide an instant library on aquaponics. They are provided here as an important time saver to those seeking technical and popular information on this topic. University libraries carry scientific journals (e.g., Aquaculture International, Aquacultural Engineering) and trade magazines (Aquaculture, Greenhouse Management and Production), and they offer on-site photocopying services to library visitors. Inter-Library Loan is a service available through most local libraries, and can provide photocopies of articles for a small fee.
Please note The Growing Edge, Aquaponics Journal, and Practical Hydroponics & Greenhouses are the most relevant trade magazines for aquaponics, recirculating aquaculture, hydroponics, and related topics, including farmer profiles. However, they are relatively new and less widely distributed in university libraries. For a complete list of articles and back issues available through these trade magazines, see the publisher’s websites:

Dissertations (PhD) and theses (Masters degree) on integrated aquaculture-hydroponic systems can provide critical access to research data and literature reviews. For example, the Speraneos in Missouri and Gordon Watkins in Arkansas used Mark McMurtry’s dissertation from North Carolina State University as a guide in the design of their systems. The UMI ProQuest Digital Dissertations database (see below) provides public Web access to titles and abstracts, via keyword and author search. Print copies are available for sale. Land-grant university libraries — through fee-based subscription — provide full-text access to recent documents via the ProQuest Dissertations and Theses database. Selected titles on aquaponic systems are listed below. The thesis by Carla MacQuarrie contains a detailed description of an aquaponics facility, including parts and pumping equipment, for example. There are numerous other titles in hydroponics, aquaculture, recirculating aquaculture, tilapia, tank culture, and wastewater effluent for those who wish to explore further. Contact:
