Abstract:
Aquaponics, an integrated system with both hydroponic plant production and aquaculture fish production, is an expanding alternative agriculture system. Many key questions about the overall feasibility of aquaponic systems remain unanswered. Of particular concern for start-up and established producers alike are consumer perceptions and willingness to pay for aquaponic produce and fish. This study reports results and analysis of a consumer survey about perceptions and preferences for aquaponic-grown products that was conducted in Minnesota during Feb. 2016. Probit and ordered probit models are used to evaluate the probability of different consumer demographic segments having various levels of knowledge and perceptions about aquaponics. About one-third of respondents had previously heard of aquaponics, and upon learning more about the system through the survey, respondents tended to be generally neutral or favorable to aquaponics. Price might be an issue for many consumers, but many tend to believe that aquaponics can impact the environment in a positive way. The results represent a first step toward building knowledge about the potential consumer base for aquaponics, which is a critical piece in the system’s potential overall profitability. It appears that consumer education and marketing will be key for the expansion of the market.

Abstract:
Even in highly developed food markets, aquaponic products have not yet been successfully introduced. This is particularly surprising, as aquaponics is an excellent example of a sustainable circulation food production system. The purpose of this empirical study was to determine the factors that influence consumers’ willingness to pay for aquaponic products. The direct and indirect relationships were tested via Structural Equation Modeling (SEM). Primary data of 315 respondents from Austria were collected. The findings revealed that the willingness to pay for aquaponic products was significantly and directly driven by the purchase intention. As a result, the successful implementation of aquaponics in the market requires the provision of information for consumers. We suggest emphasizing the value of aquaponics as a sustainable food production system, since indirect factors that influence the willingness to pay are (besides the assessment of aquaponics) environmental awareness and green consumption.

Abstract:
The study of microorganisms in aquaponics is an important topic which requires more research before exploiting the full potential of beneficial microorganisms. In this experiment, we focused on the evolution over time of the bacterial communities in four compartments of an aquaponic system i.e., the sump, the biofilter, the lettuce rhizoplane and lettuce root. We studied these communities over the course of a lettuce growth cycle via regular sampling and sequencing of the 16S rRNA gene of the collected bacteria. We also followed the physicochemical parameters of the aquaponic water throughout the experiment. Results show that a different community could be found in each compartment and that all four communities were stable throughout time and resilient to naturally occurring water parameter changes which characterize functioning aquaponic systems. Furthermore, the communities of the sump and biofilter also seem stable over the years as the predominant taxa (Luteolibacter, Flavobacterium, Nitrospira) observed in our study are similar to the ones previously reported for this aquaponic system. Finally, our results provide proof for similarities between aquaponic and soil borne lettuce root communities (gammaproteobacteria, Flavobacterium, Pseudomonadaceae, Sphingomonadaceae) thus showing that aquaponics can be similar to soil production in terms of microbial life.

Abstract:
Aquaponics, the water-reusing production of fish and crops, is taken as an example to investigate the consequences of upscaling a nature-based solution in a circular city. We developed an upscaled-aquaponic scenario for the German metropolis of Berlin, analysed the impacts, and studied the system dynamics. To meet the annual fish, tomato, and lettuce demand of Berlin’s 3.77 million residents would require approximately 370 aquaponic facilities covering a total area of 224 hectares and the use of different combinations of fish and crops: catfish/tomato (56%), catfish/lettuce (13%), and tilapia/tomato (31%). As a predominant effect, in terms of water, aquaponic production would save about 2.0 million m3 of water compared to the baseline. On the supply-side, we identified significant causal link chains concerning the Food-Water-Energy nexus at the aquaponic facility level as well as causal relations of a production relocation to Berlin. On the demand-side, a ‘freshwater pescatarian diet’ is discussed. The new and comprehensive findings at different system levels require further investigations on this topic. Upscaled aquaponics can produce a relevant contribution to Berlin’s sustainability and to implement it, research is needed to find suitable sites for local aquaponics in Berlin, possibly inside buildings, on urban roofscape, or in peri-urban areas.

Abstract:
Aquaponic systems are an integrated way to produce fish and plants together with mutual benefits. Fish provide nutrients to plants on the one side, and plant nutrients uptake allow water reuse for fish on the other side. In this kind of system, the use of phytosanitary treatments to control plant pathogens is sensitive because of the risk of toxicity for fish present in the same water loop, especially coupled aquaponics. Among plant pathogens, Pythium aphanidermatum is a most problematic microorganism due to the Oomycete’s capacity to produce mobile form of dispersion (zoospores) in the recirculated water. Therefore, this study aimed at elucidating the potential antagonistic capacity of aquaponic water against P. aphanidermatum diseases. It was shown that aquaponic water presented an inhibitory effect on P. aphanidermatum mycelial growth in in vitro conditions. The same result was observed when lettuce plants growing in aquaponic water were inoculated by the same plant pathogen. Aquaponic lettuce was then compared to lettuce grown in hydroponic water or complemented aquaponic water (aquaponic water plus mineral nutrients). The disease was suppressed in the presence of aquaponic water, contrary to lettuce grown in hydroponic water or complemented aquaponic water. Root microbiota were analyzed by 16S rDNA and ITS Illumina sequencing to determine the cause of this aquaponic suppressive action. It was determined that the diversity and the composition of the root microbiota were significantly correlated with the suppressive effect of aquaponic water. Several taxa identified by metabarcoding were suspected to be involved in this effect. Moreover, few of these microorganisms, at the genus level, are known to have an antagonistic effect against P. aphanidermatum. These innovative results indicate that aquaponic water could be an interesting and novel source of antagonistic agents adapted to control P. aphanidermatum diseases in soilless culture.

Abstract:
Aquaponic nutrient studies often use various types of water containing high levels of mineral nutrients for water supply, making it difficult to accurately determine deficient nutrients limiting crop yield and quality across the systems. To avoid interference with background nutrients, we used reverse osmosis water in this study. The objectives were to identify critical nutrients that affect the yield and quality of cherry tomato-, basil-, and lettuce by characterizing nutrient composition and concentration in aquaponic systems in comparison to hydroponic systems. Daily release rate (mg L−1) of macronutrients derived from fish feed (41% protein, 1.1% phosphorus, 1% fish weight) was in decreasing order of SO4–S (16) > PO4–P (2.4) > NO3–N (1.0) > K (0.8) > Cl (0.5) > NH4–N (0.4) > Ca (0.2) > NO2–N (0.13) > Na (0.11) > Mg (0.02), in which daily inputs of Mg and Ca in aquaponics were found to be only 1–2% and 4–6%, respectively, of those in hydroponics. Subsequently, the average concentrations of all nutrients were significantly lower in aquaponics than in hydroponics during a 3-month production except for Cl, NH4–N, NO2–N, and Na. The concentration of Mg remained below 5 mg L−1 in all aquaponic systems, while the concentration of Ca rapidly decreased in tomato-based aquaponics, especially during fruiting. SPAD value (chlorophyll content) was associated with concentrations of leaf N, Mg, and/or Ca. Specifically, lower SPAD value was correlated with lower leaf Mg and Ca for tomato and lower leaf Mg for basil but neither Mg nor Ca for lettuce. The aquaponic solution contained nearly six-times higher Na than the hydroponic solution, resulting in three-times higher Na concentration in the edible portion of the crops. Compared to a lettuce-based aquaponic system, tomato- and basil-based systems retained more desirable water quality parameters (i.e., stable pH, lower temperature), had lower electrical conductivity (EC) via greater biomass production and, therefore, more efficient nutrient removal, and had lower feed conversion rate and higher fish biomass increment. Regardless of crop species, vegetative shoot biomass was significantly reduced in aquaponics than in hydroponics. However, the marketable yield of tomatoes was similar between aquaponics and hydroponics, while those of basil and lettuce were reduced in aquaponics by 56% and 67%, respectively, in comparison to hydroponics. Our results highlighted potential solutions to design proper nutrient management practices essential for the development of successful aquaponic production systems. Considering that ingested fish feed does not provide sufficient levels of Mg and/or Ca for crop production, it is suggested to supplement Mg before crop transplanting and Ca before fruiting of fruity crops to improve crop growth and quality in aquaponic systems, especially when high-quality water is used for water supply.

Aquapon technology has a positive effect on the growth of live weight of Clary catfish per 1m3 of the water environment in comparison with ultrasound. As a result, this indicator in the aquapon installation was higher by 456 grams or 1.1% for 45 days ompared to the USV. Profitability cleavage catfish in aquaponic operation installation was 22.8%, which is 1.4% higher than the same indicator of RAS. The combined aquaponic-hydroponic mode of operation of the unit allowed to obtain 8.282 kg of vegetative mass of lettuce plants from 1 m2 of the installation area for 45 days, which is 2.761 kg more than in the traditional aquaponic mode and 0.903 kg more than in the hydroponic mode.

Abstract:
Aquaponic production combines intensive production with waste recycling and water conservation. Aquaponic join recirculating aquaculture with hydroponics to use nutrient waste from aquaculture as an input to plant growth. Traditional aquaculture systems treat or dispose nutrient-rich wastewater. In aquaponics, the waste products from the fish are converted by a bio-fi lter into soluble nutrients which are absorbed by the plants, and allow “clean” water to be returned back to the fish. Thus, it produces valuable fish protein with a minimal pollution of fresh water resources, while at the same time producing horticultural crops. Fish in aquaponic production systems can be raised in ponds, tanks, or other containers. Plants are grown separately in hydroponic tanks, submerged in water but suspended in gravel, sand, perlite, or porous plastic films, as well as on floating rafts. Systems vary greatly in design and construction, but most perform the following key functions: finfish and plant production, removal of suspended solids, and bacterial nitrification. This review discusses applications, effects and perspective of aquaponics.

Abstract:
Aquaponic is a combination of aquaculture and hydroponic plants in the recirculation system. The aquaponic system has a constraint in the form of ammonia which is produced by fish metabolism. In order to increase the productivity of fish and plants in aquaponics, an approach by integrating filters and biofilter could be used to reduce ammonia waste. The aim of this research was to study the use of zeolite, charcoal, and water spinach as components of integrated filters to reduce ammonia concentration in an aquaponic system. This research was conducted for four weeks with three repetitions of water sampling sourced from pond, filters, and output. The results of this study indicated that the use of combination of zeolite, charcoal and water spinach as componentof integrated filters can reduce ammonia throughout the research period.

Current aquaponic technology ranges from backyard hobbyist to technologically advanced commercial production. A single source for protein (fish) and nutrients/vitamins (vegetables), development of a technologically simplified commercial-scale system is a realistic solution for many impoverished nations. This study develops a simplified aquaponic facility to be implemented in rural northern Uganda. Research objectives were to: (1) identify simplified commercial-scale system design components, (2) establish a water quality baseline, (3) identify plant/tilapia production ratios, (4) identify construction materials available in northern Uganda, (5) integrate culturally familiar elements, (6) complete preliminary facility design, and (7) calculate facility water balance. The study established that a viable simplified design achieves: (1) water circulation with weir gravity flow and one return pump, (2) tank cleaning with strategically sloped floors and manual waste siphoning, and (3) breeding control with raised bottom fishnets. Submerged aeration is critical to optimal fish growth, and cannot be eliminated despite surface aeration’s low energy appeal. Baseline water quality parameter values of DO > 3 mg/L, pH > 5.5, and TAN > 3 mg/L (2 mg/L average) were established for the pilot study configuration and hydraulic retention time (HRT). A plant/tilapia ratio of 2.5 ft[superscript]2/lb was identified for the proposed facility’s design. The simplified design was assessed compatible with concrete block construction local to northern Uganda. Incorporating the following culturally familiar elements will facilitate technology adoption: utilize native fish (tilapia) and vegetable crops identified in community markets, replace commercially produced plant tank raft components with woven matting from locally available natural materials, and identify the unfamiliar proposed tank design with newly adopted raceway culture techniques at a well-known Ugandan national fishery institute. A proposed facility preliminary design represents local materials, identified plant/tilapia ratio, minimum HRT, and simplified design components for tilapia densities ranging from 12 to 3 gal/lb. With the facility supplied by both rainwater and groundwater, corresponding water balances for 12 to 3 gal/lb densities ranged from a 9,735 gal/yr well supply demand to a 10,984 gal/yr rainwater surplus.

Abstract:
Insect meal has excellent potential as food or feed. There is a need to provide enough food for the growing population, which is linked to the increasing demand for livestock production. Meat and fish have always been the staple of the human diet as a rich source of proteins and fats for human nutrition. Fish is a good source of animal protein and fat for humans, which forms the basis of the diet of a large number of people who generally live in coastal areas. The increasing demand for fish is associated with a growing interest in high-quality and affordable fish feed. Nowadays, the main ingredient in fish feed is fishmeal, and the price is constantly increasing. The sustainability of the aquaculture industry depends on finding a substitute for fishmeal with the same nutritional value and availability. Recently, there has been a growing interest in animal protein from insects for fish fattening. This thesis focused on analysing insect meal from mealworm larvae (Tenebrio molitor) and its use for food and feed purposes. The theoretical part describes the mealworm, the use of insect meal for human nutrition, and fish fattening. It also describes the requirements of fish for individual nutrients and the characterisation of insects for feeding purposes, focusing on the mealworm used as an alternative feed ingredient in fish. The individual major nutrients, namely protein, lipids, fatty acids, amino acids, fibre, chitin, and selected minerals, were determined in the experimental part. The experimental part was divided into two parts, and the first part was divided into two phases. The first phase was used to determine the nutritional components in two fractions of insect meal from Tenebrio molitor larvae. The first fraction contained the fine fraction, and the second fraction the coarse fraction of insect meal. In the second phase, the content of nutritionally significant components was only determined in the insect meal from dried larvae without fractionation. A fish feed was designed from the analyses results. In the second part, the effect of the addition of insect meal from Tenebrio molitor for food purposes was investigated; specifically, the sensory properties of muffins were monitored. From the results, it can be observed that the nutritional composition of the insect meal suggests the possibility of using the mealworm larvae as an ingredient in the fish diet. The insect meal contains a high proportion of valuable proteins and lipids necessary for fish farming and a low proportion of carbohydrates, which unlike humans, fish do not need in their diet. The sensory analysis results indicate that consumers are not prepared to eat foods with added insects.

Abstract:
Aquaponik-Systeme stellen an sich einen sehr nachhaltigen, innovativen Ansatz für die zukünftige Lebensmittelproduktion dar. Allerdings hat sich bis heute noch kein flächendeckender, ökonomischer Erfolg eingestellt und wesentliche systemische Engpässe wurden wissenschaftlich nicht untersucht. Daher waren die Hauptziele dieser Dissertation, (I) sichere Nitratkonzentrationen in geschlossenen Kreislaufanlagen (RAS) zu ermitteln, unter denen optimales Wachstum und Tierwohl produzierter Tilapien gewährleistet ist, (II) die Evaluierung des besten Designkonzeptes für die optimale, kombinierte Produktion von Fisch und Pflanzen und (III) die allgemeine Effizienz bei der Wiederverwertung des Abwassers und der Nährstoffe aus dem Schlamm der mechanischen Filtrationseinheiten in aquaponischen Systemen zu erhöhen. Das Wachstum und die Gesundheit von Niltilapien (Oreochromis niloticus) wird durch hohe Nitratkonzentrationen (> 500 mgL-1 NO3--N) negativ beeinflusst. Nitratkonzentrationen, die für die Produktion von Pflanzen in aquaponischen Systemen (~ 200 mgL-1 NO3--N) optimal sind, haben keinen negativen Einfluss auf das Tierwohl. Entkoppelte Kreislaufsysteme sind bei einer professionellen aquaponischen Produktion von Fisch und Pflanzen zu bevorzugen. Bei der Produktion von Fisch ergab sich keinerlei Unterschied, jedoch wurde eine deutlich gesteigerte Tomatenproduktion von 36 % in entkoppelten Kreislaufsystemen erreicht. Die aerobe Mineralisation zeigte das beste Rückgewinnungpotential von Phosphat und nur geringe Nitratverluste und kann in der Gesamtheit eine deutliche Effizienzsteigerung aquaponischer Systeme zur Folge haben. Die Ergebnisse dieser Dissertation zeigen die Engpässe in der Aquaponik klar auf und liefern gleichzeitig Lösungsansätze, wie diese Hindernisse in Bezug auf das Nährstoff- und Ressourcenmanagement überwunden werden können. Dadurch kann die Nachhaltigkeit dieser Anlagen gesteigert und die Wahrscheinlichkeit des wirtschaftlichen Erfolges erhöht werden.
Aquaponics is the combination of fish production in aquaculture and hydroponic (soilless) production of crop plants. Despite of representing already a sustainable, innovative approach for future food production systems, aquaponics are still missing economic success and up to date major bottlenecks were not scientifically addressed. Therefore the main aims of this thesis were (I) to identify safe nitrate concentrations under which best growth and health status of tilapia can be guaranteed in aquaponics, (II) to evaluate the best design concept for an optimal combined production of fish and plants and (III) to increase the overall system efficiency by recycling waste water and nutrients deposited in the sludge of the mechanical filtration unit. The growth and health status of Nile tilapia (Oreochromis niloticus) is negatively affected by high nitrate concentrations (> 500 mgL-1 NO3--N) commonly reported for RAS. Nevertheless, optimal nitrate concentrations for plant production in aquaponic systems (~ 200 mgL-1 NO3--N) are not affecting fish welfare and allow for an efficient production of Nile tilapia. Decoupled aquaponics proved to be favorable for professional aquaponic production, whereas coupled systems were suboptimal for a combined production of fish and plants. There were no differences in fish production, whereas tomato production within the decoupled system was considerably increased by 36 %. Aerobic mineralization of phosphate revealed best phosphate recovery with only minor losses of nitrate. Recycling of water sludge mixture from clarifiers resulted in a substantial phosphor recovery, an increase in potassium and additional water savings. Conclusively, the results of this holistic thesis clearly revealed the bottlenecks in aquaponic technology and provided guidance in overcoming mayor obstacles in terms of optimized nutrient and resource management to increase the overall sustainability of these systems and improve production efficiency and profitability.

ENGLISH ABSTRACT: Stellenbosch University was approached to assist with developing a techno-financial model for an urban freshwater aquaculture system in Philippi, Cape Town. Rapidly growing urban areas are predominantly becoming concentrated zones for malnutrition and poverty which require attention. Having enough food to eat does not mean that a family is food secure, the problem is usually associated with the lack of access to nutritious food. Fish is seen as an extremely healthy food which has the potential to effectively support food security and alleviate malnutrition. Aquaculture is identified as a largely underdeveloped sector in South Africa. It is currently undergoing rapid transition, being promoted by government as an industry that has potential to develop and create jobs, provide food security and grow the South African economy. Aquaponics- a method to integrate aquaculture with growing crops in a symbiotic system is a highly resource efficient closed-integrated food producing technology which has the potential to benefit from South African biosecurity regulations and climate-geographic characteristics. It is viewed as an effective food production alternative to deal with the challenges of declining high quality freshwater resources and available arable land. Training and capacity building is important for the development of aquaponic technology. This study explores and identifies the advantages aquaponic technology development would have in South Africa. The study has reviewed and assessed the fundamental principles for aquaculture production and management required for aquaponic systems development and management. A practical case study identifies the daily challenges and design parameters of aquaponic systems. The study is concluded with a techno-financial project proposal which shows how aquaponic systems can be planned.

Abstract:
This study was done with the aim of deepening the understanding of the Maya Chay aquaponic systems. To meet the aim, a literature study on aquaponics, with an emphasis on the nitrogen metabolism in such systems, was conducted. Furthermore, a deep investigation of the specific Maya Chay systems was made to understand how these systems might be different from the general aquaponic designs. Finally, two nitrogen balances were developed with the purpose of examining the dynamics of the nitrogen transformations in two Maya Chay aquaponic systems. The measurements for the nitrogen balances was made between Mars 2017 to July 2017, and the model for the nitrogen balances evaluated the amount of nitrogen as: i) nitrogen input to the system through the feed, ii) nitrogen assimilated by the fish and the plants, iii) nitrogen accumulated in the sludge, and iv) nitrogen lost to the atmosphere through denitrification and similar processes such as anammox. The resulting nitrogen balances showed some interesting differences in the dynamics of nitrogen distribution. In the smaller Maya Chay XS system in Antigua, only 36 % of the nitrogen input was assimilated by the fish (30 %) and the plants (6 %) and 64 % of the nitrogen input could be regarded as lost, either to the atmosphere (46 %) or in the sludge (18 %). The other nitrogen balance showed that the distribution of nitrogen in the Maya Chay S system in Chinautla is much more efficient in taking care of the nitrogen input. In this system 70 % was assimilated by the fish (33 %) and the vegetables (37 %) and the remaining 30 % was lost, either to the atmosphere (14 %) or in the sludge (16 %). The nitrogen balances also showed that both systems are almost equally efficient in terms of nitrogen assimilation by the fish, and that the big differences lie in the rate of nitrogen assimilation by the plants (6 % vs. 30 %) and in the nitrogen loss to the atmosphere (46 % vs. 14 %). A likely explanation for these differences is the difference in design of the vegetable beds, where the less efficient system in Antigua has a large surface area for the vegetable bed, but only a small portion of this could be utilized for vegetable growth. Furthermore, a consequence of the larger surface is a larger anoxic zone in the bottom of the vegetable bed, which promotes the growth of denitrifying and anammox bacteria. These kinds of bacteria convert the dissolved ammonia, nitrite and nitrate to gas forms of nitrogen, such as nitrogen gas and nitrous oxide and thus nitrogen is lost from the system to the atmosphere. Finally, this study also showed a great difference in the ratio of vegetable to fish production between the systems, where the ratio was 0.43 in Antigua and 2.7 in Chinautla. This ratio further indicates the difference in design between the systems, especially regarding the vegetable beds, has an impact on how well they perform, both in terms in economic and productivity terms, but also in terms of the release of greenhouse gases (nitrous oxide). It can therefore be concluded that the original design of the Maya Chay system (i.e. the Chinautla system) is the preferable one. Even though the accuracy of the measurements in the experiments could be improved for future studies, this study has demonstrated the value of making nitrogen balances for aquaponic systems. Nitrogen balances increase the knowledge of the performance of the system and they increase the understanding of the dynamics of nitrogen transformations that takes place in the system. This knowledge can then be utilized to adjust the design and/or verify if either the aquaculture or hydroponic system is properly designed.
Den här studien gjordes med syftet att fördjupa förståelsen kring Maya Chay akvaponiska system. För att uppnå syftet, utfördes en litteraturstudie som fokuserade på metabolismen av kväve i sådana system. Vidare undersöktes specifika Maya Chay system för att förstå hur dessa system skulle kunna skilja sig från den generella akvaponiska designen. Slutligen utvecklades två kvävebalanser i syfte att utforska dynamiken i de kväveomvandlingar som sker i två Maya Chay akvaponiska system. Mätningarna för kvävebalanserna gjordes i perioden mars 2017 till juli 2017, och modellen för kvävebalanserna utvärderade mängden kväve som: i) kväve som tillförts till systemet genom fodret, ii) kväve som assimilerats av fiskarna och växterna, iii) kväve som ackumulerats i slammet, och iv) kväve som gått förlorat till atmosfären genom denitrifikation och liknande processer så som anammox. Resultaten från kvävebalanserna visade intressanta skillnader kring dynamiken av kvävefördelningen. I det mindre Maya Chay XS systemet i Antigua, assimilerades endast 36 % av kvävet av fiskarna (30 %) och växterna (6 %) och 64 % av kvävet ansågs som förluster, antingen till atmosfären (46 %) eller genom slammet (18 %). Den andra kvävebalansen visade att fördelningen av kväve i Maya Chay S systemet i Chinautla är mycket mer effektivt gällande tillvaratagandet av tillfört kväve. I detta system assimilerades 70 % av fiskarna (33 %) och av växterna (37 %) och de resterande 30 % gick förlorat, antingen till atmosfären (14 %) eller i slammet (16 %). Kvävebalanserna visade även att bägge systemen är mer eller mindre likvärdiga gällande assimilering av kväve från fiskarna, och att den stora skillnaden mellan systemen ligger i hur mycket kväve som assimilerats av växterna (6 % vs. 37 %) samt hur mycket kväve som gått förlorat till atmosfären (46 % vs. 14 %). En sannolik förklaring till dessa skillnader är skillnaden i designen av växtbäddarna för två systemen, där det mindre effektiva systemet i Antigua har större area för växtbädden, men endast en mindre del av denna kunde nyttjas för odling av grönsaker. Som konsekvens av den större arean av växtbädden är en större volym syrefattigt vatten i botten av växtbädden, vilket verkar för tillväxt av denitrifierande och anammoxa bakterier. Dessa typer av bakterier omvandlar den upplösta ammoniaken, nitriten samt nitratet till kväveföreningar i gasform, till exempel kvävgas och lustgas och därav går kvävet förlorat till atmosfären. Slutligen visade den här studien stora skillnader i förhållandet mellan växt- och fisk-produktion mellan de två systemen, där förhållandet var 0.43 i Antigua och 2.7 i Chinautla. Skillnaden mellan de två olika förhållandena är ytterligare en indikation till att skillnaden i designen mellan systemen, speciellt med avseende på växtbäddarna, har en effekt på hur väl systemen presterar, både i termer som ekonomi och produktivitet, men också i termer som utsläpp av växthusgaser (lustgas). Därför kan slutsatsen dras att den ursprungliga designen av Maya Chay systemen (det vill säga systemet i Chinautla) är att föredra. Även om noggrannheten i mätningarna i detta experiment skulle kunna förbättras i framtida experiment, så visar denna studie värdet av att utföra kvävebalanser för akvaponiska system. Kvävebalanserna ökar kunskapen om hur väl systemen fungerar och dom ökar kunskapen kring dynamiken i kväveomvandlingarna som sker i systemen. Denna kunskap kan sedan utnyttjas för att justera designen av systemen och/eller verifiera om antingen vattenbruksdelen eller hydroponidelen i systemet är feldimensionerad.

Abstract:
AbstractIncreased public interest in aquaponics necessitates a greater need to monitor fish health to minimize risk of infectious and non-infectious disease outbreaks which result from problematic biosecurity. Fish losses due to health and disease, as well as reporting of poor management practices and quality in produce, which could in a worst-case scenario affect human health, can lead to serious economic and reputational vulnerability for the aquaponics industry. The complexity of aquaponic systems prevents using many antimicrobial/antiparasitic agents or disinfectants to eradicate diseases or parasites. In this chapter, we provide an overview of potential hazards in terms of risks related to aquatic animal health and describe preventive approaches specific to aquaponic systems.

Abstract:
AbstractAmong the diversity of plant diseases occurring in aquaponics, soil-borne pathogens, such as Fusarium spp., Phytophthora spp. and Pythium spp., are the most problematic due to their preference for humid/aquatic environment conditions. Phytophthora spp. and Pythium spp. which belong to the Oomycetes pseudo-fungi require special attention because of their mobile form of dispersion, the so-called zoospores that can move freely and actively in liquid water. In coupled aquaponics, curative methods are still limited because of the possible toxicity of pesticides and chemical agents for fish and beneficial bacteria (e.g. nitrifying bacteria of the biofilter). Furthermore, the development of biocontrol agents for aquaponic use is still at its beginning. Consequently, ways to control the initial infection and the progression of a disease are mainly based on preventive actions and water physical treatments. However, suppressive action (suppression) could happen in aquaponic environment considering recent papers and the suppressive activity already highlighted in hydroponics. In addition, aquaponic water contains organic matter that could promote establishment and growth of heterotrophic bacteria in the system or even improve plant growth and viability directly. With regards to organic hydroponics (i.e. use of organic fertilisation and organic plant media), these bacteria could act as antagonist agents or as plant defence elicitors to protect plants from diseases. In the future, research on the disease suppressive ability of the aquaponic biotope must be increased, as well as isolation, characterisation and formulation of microbial plant pathogen antagonists. Finally, a good knowledge in the rapid identification of pathogens, combined with control methods and diseases monitoring, as recommended in integrated plant pest management, is the key to an efficient control of plant diseases in aquaponics.

Abstract:
AbstractFish and feed waste provide most of the nutrients required by the plants in aquaponics if the optimum ratio between daily fish feed inputs and the plant growing area is sustained. Thus, the fish feed needs to fulfil both the fish’s and plant’s nutritional requirements in an aquaponic system. A controlled fish waste production strategy where the nitrogen, phosphorus and mineral contents of fish diets are manipulated and used provides a way of influencing the rates of accumulation of nutrients, thereby reducing the need for the additional supplementation of nutrients. To optimize the performance and cost-effectiveness of aquaponic production, fish diets and feeding schedules should be designed carefully to provide nutrients at the right level and time to complement fish, bacteria and plants. To achieve this, a species-specific tailor-made aquaponic feed may be optimized to suit the aquaponic system as a whole. The optimal point would be determined based on overall system performance parameters, including economic and environmental sustainability measures. This chapter thus focuses on fish diets and feed and reviews the state of the art in fish diets, ingredients and additives, as well as the nutritional/sustainable challenges that need to be considered when producing specific aquaponic feeds.

AbstractThis chapter presents some examples of recent initiatives by social enterprises using aquaponics. Aquaponics offers an innovative form of therapeutic horticulture, which can provide employment and promote well-being for people with disabilities. If implemented as a program to be managed by local communities, aquaponic systems also have the potential to address issues such as food security and food sovereignty, especially in urban areas. Increasing public familiarity with aquaponics has seen a number of social ventures being set up around the world. However, the viability of these depends not only on stakeholder commitment, thorough market analysis, clear governance structures, and a robust business plan but also on external factors, such as the local political context and regulations.

Abstract:
AbstractAquaponics’ potential to transform urban food production has been documented in a rapid increase of academic research and public interest in the field. To translate this publicity into real-world impact, the creation of commercial farms and their relationship to the urban environment have to be further examined. This research has to bridge the gap between existing literature on growing system performance and urban metabolic flows by considering the built form of aquaponic farms. To assess the potential for urban integration of aquaponics, existing case studies are classified by the typology of their building enclosure, with the two main categories being greenhouses and indoor environments. This classification allows for some assumptions about the farms’ performance in their context, but a more in-depth life cycle assessment (LCA) is necessary to evaluate different configurations. The LCA approach is presented as a way to inventory design criteria and respective strategies which can influence the environmental impact of aquaponic systems in the context of urban built environments.

Abstract:
AbstractAquaponic systems are often designated as sustainable food production systems that are still facing various challenges, especially when they are considered as a commercial endeavour that needs to compete on the market. The early stages of the aquaponics industry have witnessed a number of unrealistic statements about the economic advantageousness of aquaponics. This chapter deals with these topics and discusses them critically. The latest scientific literature and current personal experiences of European commercial aquaponics farmers are taken into account on three levels: The horticulture side of production, the aquaculture side of production and the early data on the market response to aquaponics, emphasising the marketing issues and public acceptance of aquaponics. In summary, the chapter does not provide an “off-the-peg” solution to evaluate the economic performance of a particular aquaponics system. Instead it provides a broad database that enables an estimation of the efficiency of a planned system more realistically, pointing to challenges that the commercial aquaponics early adopters faced that are important lessons for future aquaponic endeavours, particularly in Europe.

Abstract:
AbstractRecirculating aquaculture systems, as part of aquaponic units, are effective in producing aquatic animals with a minimal water consumption through effective treatment stages. Nevertheless, the concentrated sludge produced after the solid filtration stage, comprising organic matter and valuable nutrients, is most often discarded. One of the latest developments in aquaponic technology aims to reduce this potential negative environmental impact and to increase the nutrient recycling by treating the sludge on-site. For this purpose, microbial aerobic and anaerobic treatments, dealt with either individually or in a combined approach, provide very promising opportunities to simultaneously reduce the organic waste as well as to recover valuable nutrients such as phosphorus. Anaerobic sludge treatments additionally offer the possibility of energy production since a by-product of this process is biogas, i.e. mainly methane. By applying these additional treatment steps in aquaponic units, the water and nutrient recycling efficiency is improved and the dependency on external fertiliser can be reduced, thereby enhancing the sustainability of the system in terms of resource utilisation. Overall, this can pave the way for the economic improvement of aquaponic systems because costs for waste disposal and fertiliser acquisition are decreased.

Abstract:
AbstractAquaponics is a technology that is part of the broader integrated agri-aquaculture systems discipline which seeks to combine animal and plant culture technologies to confer advantages and conserve nutrients and other biological and economic resources. It emerged in the USA in the early 1970s and has recently seen a resurgence, especially in Europe. Whilst aquaponics broadly combines recirculating fish culture with hydroponic plant production, the application of the term aquaponic is broad and many technologies claim use of the name. Combining fish culture with aquatic-based, terrestrial plant culture via aquaponics may be better defined via its nutrient resource sharing credentials. Aquaponics applies several principles including, but not limited to, efficient water use, efficient nutrient use, lowered or negated environmental impact and the application of biological and ecological approaches to agricultural fish and plant production. Water sources are important so that the nutrients required for fish and plant production are available and balanced, and system water chemistry is paramount to optimised fish and plant production. Systems may be configured in several ways, including those that are fully recirculating and those that are decoupled. Aquaponics importantly seeks to apply methods that provide technical, biological, chemical, environmental and economic advantages.

AbstractThe call for sustainable food production and consumption has led to an increased interest and new policy measures to support the circular economy and climate-smart farming practices. The merits of aquaponics and closed-loop nutrient cycling systems are increasingly being examined in terms of sustainable productivity in various settings including urban environments. Aquaponics also has the potential to be applied as a learning tool for people of all ages but especially for young people at school. This chapter studies the potential of aquaponics to teach food and science literacy and the use of the technology as an educational tool in primary school. The chapter draws on data from the Growing Blue & Green (GBG) program carried out in cooperation among Aalborg University, Copenhagen, municipal schools and their teachers and a private aquaponic enterprise. The chapter draws on three empirical studies including an exploratory study on the educational opportunities at school, a feasibility study carried out among teachers, as well as the educational Growing Blue & Green (eGBG) study, in which a digital-based regulation component was added. The conclusion is that low-cost versions of aquaponics have considerable potential for supportive learning in elementary school. Preliminary findings furthermore suggest that fitting the setup with easy-to-install intelligent sensors and devices offers the opportunity to provide learning about food, sustainability, and a basic understanding of the control and management of biological systems in one package.

Abstract:
Aquaponics is an eco-friendly system for food production utilizing aquaculture and hydroponics to cultivate fish and crop without soil. It is an inexpensive symbiotic cycle between the fish and plant. In an aquaponic system, fish waste (ammonia) is fed into the plant bed which acts as a bio-filter and takes the nitrate which is essential to grow vegetation. The fresh new water is then returned to the fish enclosure to restart the cycle. A unique advantage of an aquaponic system is conserving water more effectively compared to traditional irrigation systems. Conservation of water is accomplished by recirculating water between the plant bed and the fish habitat continuously. Organic fertilization of plants using dissolved fish waste is the other benefit of aquaponics. Utilizing plants as a natural alternative to other filters, requires less monitoring of water quality. In our project, an aquaponics system was designed and built in Lyle Center for Regenerative Studies at California State Polytechnic University of Pomona. The future purpose of our project is finding an optimized situation for the aquaponics system to produce food and save water more efficiently and eco-friendly.

Abstract:
Today the United States is plagued by societal issues, economic insecurity, and increasing health problems. Societal issues include lack of community inclusion, pollution, and access to healthy foods. The high unemployment coupled with the rising cost of crude oil derivatives, and the growing general gap between cost of living and minimum wage levels contribute to a crippled consumer-driven US economy. Health concerns include increasing levels of obesity, cardiovascular disease, cancer, and diabetes. These epidemics lead to staggering economic burdens costing Americans hundreds of billions of dollars each year. It is well-known that many of the health issues impacting Americans can be directly linked to the production, availability, and quality of the food. Factors contributing to the availability of food include reduction of United States farmland, an increase in food imported from overseas, and the cost of goods to the consumer. The quality of food is influenced by the method of growth as well as imposed preservation techniques to support food transportation and distribution. At the same time, it has become increasingly common to implement biotechnology in genetically modified crops for direct human food or indirectly as a livestock feed for animals consumed by humans. Crops are also routinely dosed with pesticides and hormones in an attempt to increase productivity and revenue, with little consideration or understanding of the long term health effects. Research shows that community gardens positively impact local employment, community involvement and inclusivity, and the diets of not only those involved in food production, but all members of their households. The purpose of this work is to determine the feasibility of an energy efficient large-scale aquaponic food production and distribution facility which could directly mitigate growing socioeconomic concerns in the US through applied best practices in sustainability. Aquaponics is a symbiotic relationship between aquaculture and hydroponics, where fish and plants grow harmoniously. The energy efficient facility would be located in an urban area, and employ solar panels, natural lighting, rain water reclamation, and a floor plan optimized for maximum food yield and energy efficiency. Examples of potential crops include multiple species of berries, corn, leafy vegetables, tomatoes, peppers, squash, and carrots. Potential livestock include responsibly farmed tilapia, shrimp, crayfish, and oysters. The large scale aquaponic facility shows a lengthy period for financial return on investment whether traditional style construction of the building or a green construction style is used. However many forms of federal government aid and outside assistance exist for green construction to help drive down the risk in the higher initial investment which in the long run could end up being more profitable than going with a traditionally constructed building. Outside of financial return there are many proven, positive impacts that a large-scale aquaponic facility would have. Among these are greater social involvement and inclusivity, job creation, increased availability of fresh food, and strengthening of America’s agriculture infrastructure leading to increased American independence.

Abstract:
Abstract Aquaponic systems are a combination of hydroponics, growing plants in water, and aquaculture, growing of fish. The two subsystems are connected so that the water circulating between the two, transfers the waste from the fish tank to the plants, where the plants take in nutrients. The water is filtered by the plants and is recirculated back into the fish tank. Small-scale aquaponic systems are of particular interest, as they are appropriate for rural and developing locations to harvest both plants and fish for a local community. To improve the level of sustainability, the flow within the fish tank needs to be better understood since most of the power required to operate an aquaponic system is used by the fish-tank pump. The shape of the fish tank is of importance for the flow in the tank and the initial cost of the tank. In this work, the flow in a 2 m × 2 m square fish tank with curved corners was studied experimentally with a Vectrino Acoustic Doppler Velocimeter. Two inlet configurations were studied and compared to each other — inlets at each corner of the tank, and inlets at two of the corners of the tank. The results suggest that good recirculation can be achieved with the two inlet locations. The present work can be used for evaluating numerical simulations of the flow in the tank. The ultimate goal of the study is to develop an inlet-design configuration which minimizes initial and operational costs of the small-scale aquaponic system.

Abstract:
This paper describes the application of ‘passive house’ design principles to greenhouses, in order to provide the required thermal environment for fish and plant growth while eliminating the need for conventional cooling and heating systems. To do so, an experimental energy-efficient greenhouse with water-filled tanks that mimic an aquaponic system was designed and constructed using the ‘passive house’ design principles. The greenhouse was extensively instrumented and resulting data were used to verify and calibrate a TRNSYS dynamic simulation model of the greenhouse. The calibrated simulation model was utilized to design commercial-scale greenhouses with aquaponic systems in multiple climates. After relatively minor design and control modifications, the simulations indicate that these designs can provide the required thermal environment for fish and plant growth, while eliminating the need for conventional cooling and heating systems. The work demonstrates that the passive house standard can be applied to improve conventional greenhouse energy efficiency, and that it can be easily adapted to provide excellent performance in diverse climates.

Abstract:
Aquaponic systems combine recirculating aquaculture (growing of fish) with hydroponics (growing of plants in water). The fish in the recirculating aquaculture systems provide nutrients for the plants and the plants remove excess nutrients from the water, making these systems more efficient than traditional farming methods in terms of nutrient utilization. Small, recirculating aquaponic systems may provide a more sustainable and cost-effective alternative for securing food supply in both developing and developed nations. Recirculating aquaculture systems tend to be capital-intensive and require significant power to circulate the water in the fish tanks, which helps with the removal of waste and the distribution of oxygen. To reduce capital costs, alternative, culture vessels made from locally available materials were investigated (i.e. square-shaped tanks, and international bulk containers - IBC). These non-standard shaped culture tanks, pose an additional challenge for proper circulation of the water as compared to traditional round tanks. To address the issue of circulation, numerical and experimental data were obtained for rectangular containers. The numerical results were obtained using OpenFoam models of the experimental setup. The experimental data were obtained by measuring flow velocities in an IBC tank using Acoustic Doppler Velocimetry. Currently the experimental data show good repeatability when data are taken for at least five minutes at each position in the tank. The focus of the continuing work is to establish a good agreement between numerical and experimental results. Ultimately the study will contribute to the design of cost-effective recirculating aquaponic fish and plant systems which require lower capital expenditures and achieve energy-efficient circulation of water in the fish culture tanks.
