Resumen

Automated aquaponic systems are an efficient solution for the treatment of wastewater from aquaculture, by integrating aquaculture and agriculture, minimizing environmental impact and maximizing water use efficiency. This study implemented an automated aquaponic system in Arequipa, Peru, designed with low-cost and open-source technology. The system successfully produced rainbow trout (Oncorhynchus mykiss Walbaum, 1792) and three varieties of lettuce (Lactuca sativa L.) while treating wastewater. Water quality parameters (pH, dissolved oxygen, temperature, nitrogen compounds) were systematically monitored. The results demonstrated compliance with Peruvian environmental standards (DS 004-2017-MINAM) and suitability for agricultural reuse. The efficient design reduced operating costs and optimized water resources, generating organic biofertilizers as valuable by-products. This research validates aquaponics as a viable model for sustainable food production and wastewater treatment in water-scarce regions.
