“…In archipelagic dryland areas, with limited water resources and dry environments, catfish aquaculture water management becomes a more complex challenge. Dry land in NTT also has the advantage of having sunlight that shines for 9 months so that the existing sunlight can help the photosynthesis process in plants properly (Lee et al, 2022). Thus, it is very supportive of the aquaponics system because the vegetables planted can grow optimally.…”

This study aims to determine ammonia, phosphate and nitrate catfish (Clarias sp) farming water in aquaponics systems with conventional systems and determine catfish farming production aquaponics systems and conventional systems. The main parameters observed are ammonia, phosphate, nitrate and fish production while supporting parameters are temperature, pH, DO, SR and fish growth. The results of the independent t test showed that the value of ammonia, phosphate nitrate and nitrate in the aquaponic system was lower (P<0.05) than the conventional system, while fish production in the aquaponic system was higher (P<0.05) than the conventional system. This research shows that aquaponic systems are suitable for development in the archipelagic dry land area.

This study was aimed to determine the effects of grow media on the mineral contents of the leaves and growth characteristics of strawberry grown under aquaponics system in a plant factory. For aquaculture, 12 fish (Cyprinus carpio) (total weight, 2.0 kg) were raised in an aquaponics tank (W 0.7 m × L 1.5 m × H 0.45 m, 472.5 L) filled with 367.5 L of water at a density of 5.44 kg•m -3 and total 34 of strawberry seedlings were transplanted in the pots filed with 200 g of orchid stone, hydroball or polyurethane sponge in the growing bed (W 0.7 m × L 1.5 m × H 0.22 m) laid out with holly acrylic sheet (140×60 mm, Ø80) on the top of the system. The pH and EC of the aquaponic solution was ranged from 7.6 to 4.9 and 0.24-0.91 dS•m -1 , respectively. The concentration of NO 3 -N was about 28% lower than that of the hydroponic standard solution, and K, Fe and B were 10, 27 and 3.8 times lower, respectively; however, the mineral contents of strawberry leaves were in the appropriate ranges with lower contents in the leaves grown with sponge media. The organic content (OM), nitrogen (N), phosphorus (P), and potassium (K) of the sludge were 61.5, 5.72, 8.92, and 0.24%, respectively. The leaf area, leaf number, and dry and fresh weights of shoot at 81 DAT were significantly higher in the hydroball, and the average number of fruits per plant was significantly higher in both the orchid stone and hydroball. There was no significant difference in the fresh and dry weights of fruits. Integrated all the results suggest that the orchid stone and hydroball media are more effective to utilize nutrients in solid particles of aquaponic solution, compared to the polyurethane sponge.

Substrates are important for plant growth as they maintain the water quality in an aquaponic system. The aim of this study was to investigate the effects of four inorganic substrates of sponge (S S ), orchid stone (S O ), hydroball (S H ), and volcanic rock (S V ) on an aquaponic system for planterior (use of plants in interior design) purposes. A recycling deep flow system was used. Kalanchoe blossfeldiana 'Peperu' seedlings and goldfish (Carassius auratus auratus) were kept together for 50 days in a small tank divided into two sections. Every day, 0.25 g of fish feed was supplied into each tank. The electrical conductivity (EC) and pH of the water were checked regularly. The nutrient concentration of the aquaponics water and the plant growth parameters were measured. The results showed that the increasing pattern of the EC strength over time was identical under the different treatments. The pH of the water fluctuated with different ranges for each treatment. Furthermore, the NH 4 + concentration in aquaponic water increased sharply from 15 to 20 days in all treatments, later becoming more stable. The NO 3 and Mg 2+ ion concentrations also sharply increased after 15 to 20 days of treatment; later, NO 3 was found to have increased in the S H , S S , and S O treatments.However, at 35 days after treatment, Mg 2+ and Ca 2+ showed a similar stable concentration trend in all treatments. An inverse relationship was observed between the Ca 2+ and HPO 4 2concentrations in all treatments. Plant heights, widths, and stem diameters of K. blossfeldiana were not significantly different among the treatments. The number of leaves, the leaf length, and the leaf width of the plants were also not statistically different among the treatments. At 50 days after the commencement of treatment, the SPAD value of plants was higher in the S H treatment than in the others. Furthermore, the numbers of branches, nodes, and flowers of plant were not significantly different among the treatments. These results indicate that the inorganic sponge, orchid stone, hydroball, and volcanic rock substrates influenced the EC, pH, and ion concentrations in aquaponics water. In addition, the period of the first 20 days is crucial to ensure stable ion concentrations in water. However, these substrates did not significantly affect the growth of K. blossfeldiana.
