“…During the entire experiment, the average temperature was 24.7 ± 1.3 °C. The water parameters pH, ammonium, nitrite and nitrate did not significantly differ among the production units (PU) (p<0.05) and continued within the range considered as acceptable for tropical fish species by the literature (Jatobá and Silva, 2015;Ribeiro et al, 2017).…”

Sport fishing is a growing segment in the fishing sector in Brazil. It is, however, an activity that depends upon young shrimp and fish offer to supply live bait demand, its extraction might result on overfishing and compromise natural stock. The intensive cultivation in water recirculation system is a worldwide trend for aquaculture, which, in addition to increasing productivity, minimizes the impact of effluent emission on the environment, reinforcing sustainability. This study analyzed the economic viability of establishing farms for the cultivation of lambari (Deutorodon iguape) in water recirculation system to meet the market demand of sport fishing for live baits. Twelve fiberglass tanks with a volume of 1500 L and a unit area of 1.32 m 2 (production units-PU) were installed in a total area of 130m 2. There were also six fiberglass tanks of 2,000 L capacity each, filled with water and 600 kg of clamshells acting as biological filter. Three production cycles were performed, each lasting 60 days. In each cycle 10,800 D. iguape fingerlings were added, acquired from local fish farming, at a 600 fish m-3 density, totalizing 900 fish per PU, with medium size and weight of 10 ± 1.2 mm e 1.1 ± 0.29 g. We used the following indicators: modified internal rate of return (MIRR), net present value (NPV), annualized net present value (ANPV) and payback period (PP). The best scenario, with 90% survival rate and unitary selling prices of US$ 0.30, showed MIRR 33.19%, NPV (10%) US$ 42,174.03, ANPV (10%) US$ 6,863.63 and PP 0.9 years, demonstrating be interesting the production of live baits in the conditions proposed in this study.

“…As the present study is an experiment to validate an aquaponic system, we initially sought to apply a more conservative density. The results obtained allow for exploring higher densities, such as those practiced by Jatoba and Silva (2015), which may promote a signi cant increase in economic-nancial indicators. Watson and Hill (2006) stated that the operating cost makes the cultivation system with water recirculation more suitable for species with high market value.…”

This study aimed to verify the economic feasibility of a small-scale aquaponics system for the production of lambari (Astyanax lacustris) for ornamental purposes or as live bait, together with lettuce (Lactuca sativa) for human consumption. The hypothesis is that this activity would be a profitable option that provides increased income to small producers. The investment needed to implement the project was US$ 40,118.06. Under these conditions, the Internal Rate of Return (IRR) values varied from 13.2%, for the lowest prices (US$ 0.15 and US$ 0.34 for lambari and lettuce, respectively), to 41.5%, in the best scenario, with a price of US$ 0.14 for lambari and US$ 0.44 for lettuce. For the live bait market, only for the lowest selling price (US$ 0.15 for lambari and US$ 0.34 and US$ 0.39 for lettuce), the IRR was below the minimum attractive rate of return which was stipulated to be 12% here in. The return on investment will be achieved between 3.38 and 6.40 years (Ornamental fish market), and between 4.29 and 8.30 years (Live bait market), depending on the sales value used. Under the proposed conditions and scenarios, the aquaponic system evaluated herein presents a moderate risk in terms of economic viability.

“…The author points out that natural food must be available to lambari during the first month, and after this period, it should be transferred to closed and intensive production systems. However, to date, only a few All data for total protein, total fat and n-3 PUFA to n-6 PUFA (polyunsaturated fatty acids) ratio were obtained from the fillet composition, except for yellowtail lambari which is consumed as a whole and therefore its body composition was reported studies with yellowtail lambari in RAS have been performed (de Moraes et al 2018;Lira et al 2018;Jatobá and Silva 2015) and no scientific information about its production in aquaponics has been published. In Brazil, the production of yellowtail lambari in aquaponics systems was initially developed by The Sao Paulo Agency of Agribusiness Technology and was applied in small coupled systems.…”

South American fish species suitable for aquaponics: a review

et al. 2021

View full text Add to dashboard Cite

Tilapia and catfish are the most popular fish species in aquaponics. However, they are not well-accepted in all markets, and finding alternative species is important in order to increase the variety of food products and meet market demands. South America has several potential fish species for aquaponics systems. Encouraging the implementation of integrated aquaculture systems by providing information about the production of South American species can help to increase the supply of high-quality food and aquaculture diversification. Thus, data for five South American fish species with potential for aquaponics were compared with existing data for the main traditional warm water species in this system, tilapia and catfish. Moreover, the degree of suitability of the novel species for these systems in terms of zootechnical performance, tolerance to water quality and nutritional composition of fish flesh were discussed. The South American species considered were jundia or silver catfish (Rhamdia quelen), yellowtail lambari (Astyanax lacustris), pacu (Piaractus mesopotamicus), tambaqui (Colossoma macropomum) and snook (Centropomus spp.). Their description and the tabular comparison with the most traditional aquaponic-cultured species show they are suited for this production system. How suitable they are will depend on the system design, as well as the regional characteristics of the market where they will be produced.
