The classical working principle of aquaponics is to provide nutrient-rich aquacultural water a hydroponic plant culture unit, which in turn depurates the that returned aquaculture tanks. A known drawback compromise away from optimal growing conditions for plants and fish must be achieved produce both crops same environmental conditions. objective this study was develop theoretical concept decoupled aquaponic system (DAPS), predict water, nutrient (N P), fish, sludge, levels. This has been...

Nutrients that are contained in aquaculture effluent may not supply sufficient levels of nutrients for proper plant development and growth hydroponics; therefore, they need to be supplemented. To determine the required level supplementation, three identical aquaponic systems (A, B, C) one hydroponic system (D) were stocked with lettuce, mint, mushroom herbs. The Nile tilapia. System A only received derived from fish feed; B feed as well weekly supplements micronutrients Fe; C same...

Aquaponics (AP) is a food production system that combines hydroponic (HP) crop with recirculating aquaculture. Different types of systems have been used for growing crops in aquaponics. However, very few studies compared their suitability and efficiency an aquaponic context. The study presented here compares tomato yield, morphological (external) biochemical (internal) fruit quality, overall plant vitality from three different HP (nutrient film technique, drip irrigation system, floating...

Aquaponics is a production system based on the dynamic equilibrium between fish, plants, and microorganisms. In order to better understand role of microorganisms in this tripartite relationship, we studied bacterial communities hosted eight aquaponic aquaculture systems. The were analyzed by 16S rRNA gene deep sequencing. At phylum level, from all systems relatively similar with predominance Proteobacteria Bacteroidetes. genus however, present sampled more heterogeneous. biofilter samples...

The mobilization of nutrients from fish sludge (i.e., feces and uneaten feed) plays a key role in optimizing the resource utilization thus improving sustainability aquaponic systems. While several studies have documented aerobic anaerobic digestion performance aquaculture sludge, impact digestate on plant growth has yet to be understood. present study examines either an or effluent lettuce growth, by enriching mixture tap water with supernatants both batch reactors. plants grown hydroponic...

Aquaponics combines hydroponic crop production with recirculating aquaculture. These systems comprise various compartments (fish tank, biofilter, sump, table, radial flow settler and anaerobic digester), each their own specific environmental pressures, which trigger the formation of unique microbial communities. Triplicated aquaponic were used to investigate community composition during three lettuce growing cycles. The sampling individual allowed patterns be generated using amplicon...

Aquaponics is a recirculating technology that combines aquaculture with hydroponics. It allows nutrients from fish waste to feed plants and thus saves water nutrients. However, there mismatch between the provided by plant needs. Because of this, some nutrients, notably N, tend accumulate in aquaponic (APW or AP water). The aim this study was investigate how APW, which depleted P K but still rich could be further utilized. APW used mesocosm compared same source had been supplemented...

Sustainable food production has become increasingly important. Soilless cultivation systems offer several advantages, such as water and nutrient use efficiency, can be implemented where traditional agriculture is impossible. Bioponic locally or regionally available sources from organic waste streams (either fluid solid) thus contribute to closing cycles locally. Bioponics harnesses the metabolic processes of microorganisms which release nutrients matter. This study aimed set up a bioponic...

This paper reports the results of first study an aquaponic system for Pangasianodon hypophthalmus production that uses Lactuca sativa L. (lettuce) and Cichorium intybus rubifolium group (red chicory) intercropping in hydroponic section. The experiment was conducted a greenhouse at Zurich University Applied Sciences, Wädenswil, Switzerland, using nine small-scale systems (each approximately 400 L), with nutrient film technique (NFT). vegetables did not influence water temperature, pH,...

The presence and transformations of nitrogen (N) in the environment depend on a variety environmental factors but are also strongly influenced by anthropogenic activities such as modern agriculture. Understanding N within context agricultural systems is crucial for efficient use thereof. aim this study was to investigate changes concentration forms (ammonium, nitrite, nitrate organic N) an aquaponic system, order obtain insights into pressures influencing transformation processes. By...

An aquaponic system couples cultivation of plants and fish in the same aqueous medium. The consists interconnected compartments for rearing plant production, as well water filtration, with all hosting diverse microbial communities, which interact within system. Due to design, function operation mode individual compartments, each them exhibits unique biotic abiotic conditions. Elucidating how these conditions shape communities is useful understanding may affect quality water, are cultured.We...

The use of hydroponics to cultivate economic crops is an emerging agricultural practice in Nigeria. There is, however, a paucity information on the viability and valuation production systems. This study investigated hydroponics' profitability under small- medium-scale ten hydroponic farms were evaluated using financial metrics: net present value (NPV), internal rate return (IRR), benefit-cost ratio (BCR), sensitivity analysis. Sensitivity analysis based positive negative changes running cost...

High salinity, nutrient imbalance, and pathogens are some of the challenges closed soilless cultivation systems, e.g., those combining hydroponics (HP) with aquaculture effluents (AE). Plant growth-promoting microorganisms (PGPM) can support plants to cope stressing agents. To address these topics, lettuces were grown in systems (20 boxes) at an electrical conductivity around 4.2–5 mS/cm, following a full factorial design two sources five bacterial treatments. The either organic (AE) or...
