Evaluación de los residuos agrícolas cascarilla de arroz (Oryza sativa) y fibra de coco (Cocos nucifera) como sustratos para sistemas acuapónicos

The objective of this research was to evaluate rice husk and coconut fiber as substrates in the productive performance of vegetables in aquaponic systems. The study was quantitative-qualitative and was based on a simple DCA of three treatments of the rice husk and coconut fiber mixture. It started with a diagnosis of the characteristics, areas and volume of waste production. Then, the efficiency of the treatments on the aquaponic system was determined by monitoring parameters in plants (Survival, NL, NF, Height, Weight, Biomass, GR and SGR) and fish (Survival, Size, Weight, Biomass, Weight gain and GR). The costs and benefits of the system were calculated using IRR and NPV. It was found that Guayas produces 271 358.00 tons of rice husks and Manabí 3303.30 tons of coconut fiber. T3 (70% coconut fiber and 30% rice husk substrate) was the most significant (p-value <0.05) for plant survival. In fish quality, none of the treatments differed significantly. The aquaponic system was more optimal for leafy vegetables (lettuce) than for flowering vegetables (tomato and cucumber). T3 was evaluated as the most economically viable because it allows achieving profitability and recovering the initial investment to 100% in less than one year. It is concluded that the higher the coconut fiber and the lower the rice husk, the better the yield of vegetable production in aquaponic systems
