Abstract
Aquaponics is an activity that has been growing worldwide as a sustainable alternative for food production and practical implementation throughout society. The objective of this study was to develop micro-scale aquaponics with a native Brazilian species, the tambaqui (Colossoma macropomum), associated with the cultivation of microgreens, an agro-food trend, using arugula (Eruca sativa), with the aim of evaluating the economic viability of family production. For 70 days, the growth performance of 80 tambaqui juveniles (average initial weight = 61.88 g ± 8.31 g) was monitored. Two treatments with two hydroponics structures, Nutrient Film Technique (NFT) and Floating Raft Technology (FRT), each with four replications, were compared. Tambaqui survival was 100% in both treatments. The final weight of juveniles was 136.38 g (± 35.67 g) in NFT systems and 116.5 g (± 24.63 g) in FRT systems. In the four production cycles carried out, the arugula microgreens performed better in the NFT systems (157.38 g ± 21.74 g; 6.68 cm ± 0.17 cm) compared to FRT (41 g ± 6.18 g; 4.46 cm ± 0.58 cm), identifying the best hydroponic unit for the cultivation of E. sativa microgreens. Finally, the economic viability study was conducted considering the average wage in Brazil of US$ 285.66 for the implementation of a homemade aquaponic system. The possible scenarios considered a family income of two or more minimum wages for the implementation of at least one aquaponic system.
期刊介绍：
Aquaculture International is an international journal publishing original research papers, short communications, technical notes and review papers on all aspects of aquaculture.
The Journal covers topics such as the biology, physiology, pathology and genetics of cultured fish, crustaceans, molluscs and plants, especially new species; water quality of supply systems, fluctuations in water quality within farms and the environmental impacts of aquacultural operations; nutrition, feeding and stocking practices, especially as they affect the health and growth rates of cultured species; sustainable production techniques; bioengineering studies on the design and management of offshore and land-based systems; the improvement of quality and marketing of farmed products; sociological and societal impacts of aquaculture, and more.
This is the official Journal of the European Aquaculture Society.
