Abstract
Abstract This study aimed to evaluate the relationship between salinity in the performance of marine shrimp Litopenaeus vannamei and halophyte plant Sarcocornia ambigua in an aquaponic system with biofloc. The experiment was conducted for 57 days, and four treatments were evaluated: 8 psu (practical salinity unity), 16 psu, 24 psu, and 32 psu, with three replicates. Each experimental unit consisted of an 800 L tank for shrimp rearing, a 40 L settling chamber and a hydroponic bench of 0.3 m2 of planting area and density of 40 plants m−2. The tank water was continuously pumped to the settling chamber, and the supernatant was distributed on the hydroponic bench to irrigate the plants, returning to the tank by gravity. The tanks were stocked with 300 shrimp m−3 (1.6 ± 0.1 g). The shrimp were fed four times daily with a commercial diet containing 38% crude protein. Salinity affected shrimp survival, which was lower in 8 psu treatment (56.3 ± 4.7%). No salinity relationships were detected with any of the plant performance parameters; however, the highest biomass was produced at 16 psu, which is close to the isosmotic point of S. ambigua. The lowest concentrations of ammonia and nitrite and the highest concentrations of nitrate were found, through the interpolation of the data, near the 18 psu salinity. So, it is suggested that in this salinity, the absorption of ammonia by the plants is favored. The salinity also affected the concentration of dissolved orthophosphate. There was no relationship between salinity and the production of phenolic compounds and antioxidant activity in plants. The integrated cultivation of L. vannamei with S. ambigua can be carried out between salinities of 16 and 24 psu since the performance of the shrimp is not impaired, and the growth of the plants and the removal of nitrogen and phosphate compounds are favored in this range of salinity.

Whilst aquaponics may be considered in the mid-stage of development, there are a number of allied, novel methods of food production that are aligning alongside aquaponics and also which can be merged with aquaponics to deliver food efficiently and productively. These technologies include algaeponics, aeroponics, aeroaquaponics, maraponics, haloponics, biofloc technology and vertical aquaponics. Although some of these systems have undergone many years of trials and research, in most cases, much m...

ABSTRACTEffect of K+ and Mg2+ in water on the performance of Litopenaeus vannamei using bioflocs was evaluated. Control had water with K:Mg (1:4.57) and other treatments (K:Mg of 1:5.4, 1:4.65, and 1:3.77), both with salinity of 4 g/L. Initial mean weight of shrimp was 0.08 ± 0.007 g. No difference in shrimp growth performance and survival was observed (P > 0.05) except in the control. Our results suggest that it is possible to culture postlarvae of Litopenaeus vannamei in low-salinity water wit...

Aquaponia e sistema de bioflocos possuem vantagens quando comparados com sistemas convencionais de producao de alimentos, mas estudos que associam esses sistemas sao incipientes. O objetivo deste estudo foi avaliar o desenvolvimento de Lactuca sativa em sistemas hidroponicos e aquaponicos (com Rhamdia quelen) com ou sem bioflocos e utilizando minima infraestrutura. Hidroponia (H-system), aquaponia (Aqua) e aquaponia com bioflocos (Aqua-BF) foram avaliados em delineamento inteiramente casualizado...

Abstract Aquaponics production is emerging as an alternative for effluent treatment and aquaculture diversification. Also, aquaponics contributes to save water and for the maximum utilization of nutrients and culture areas. The objective of this research was to evaluate the effluent derived from biofloc technology (BFT) tilapia culture on the aquaponics production of three varieties of lettuce Lactuca sativa : red lettuce, butter lettuce, and crispy lettuce, using the clear-water recirculation s...

Aquacultural effluents are rich in P, a growing concern worldwide for potential environmental pollution. Thus integrating aquaculture with agriculture, e.g. aquaponics, shows promise to enhance nutrient and water use efficiency and overall environmental sustainability. The present study was carried out to quantify a P flow, P mass balance, and evaluate P removal efficiency by hydroponic lettuce integrated with tilapia aquaculture. Also, a phosphorus dynamics simulation model was developed to be ...

Abstract The aim of this study was to evaluate the integrated culture of Sarcocornia ambigua and Pacific white shrimp in an aquaponic system with biofloc. The experiment was performed for 73 days and two treatments were evaluated: plants and control (without plants), with four replicates. Each experimental unit consisted of an 800 L tank, a 40 L conical bottom settling chamber, and a hydroponic bench with 0.4 m 2 of planting area and a capacity for 40 plants. The water from the shrimp tank was p...

Abstract In recent years, aquaponic systems have gained significant popularity as soilless agriculture systems for organic fruits and vegetables production with concomitant remediation of aquaculture effluent. Aquaponics is a potential sustainable food production system that integrates aquaculture with hydroponics in which nitrogen-rich effluent from the fish production is utilized for plant growth. Because nitrogen is one of the most important inputs in an aquaponic system, it is critical to in...

Nitrogen transformations in aquaponics with different edible plant species, i.e., tomato (Lycopersicon esculentum) and pak choi (Brassica campestris L. subsp. chinensis) were systematically examined and compared. Results showed that nitrogen utilization efficiencies (NUE) of tomato- and pak choi-based aquaponic systems were 41.3% and 34.4%, respectively. The abundance of nitrifying bacteria in tomato-based aquaponics was 4.2-folds higher than that in pak choi-based aquaponics, primarily due to i...
