Sistema acuapónico para producción de lechuga (Lactuca sativa) y parámetros productivos de la tilapia roja (Oreochromis sp) y tilapia negra (Oreochromis niloticus) en el Cantón Pedernales 2024.

Abstract

This study evaluated the implementation of an aquaponics system as a sustainable alternative for the simultaneous production of tilapia (Oreochromis niloticus) and lettuce (Lactuca sativa) on the grounds of the Universidad Laica Eloy Alfaro de Manabí, Pedernales Extension. Growth, wáter quality and system efficiency were analyzed under controlled conditions. The results indicated that the growth rate of red tilapia (T.C.E = 0.94 replicate 1 and 0.45 replicate 2) was significantly better than that of black tilapia (T.C.E = -0.28 replicate 1 and -0.78 replicate 2). The feed conversión results of red tilapia (C.A = 1.72 replicate 1 and 2.35 replicate 2) were efficient better than black tilapia (C.A = -1.83 replicate 1 and 6.11 replicate 2). Regarding lettuce production, a uniform and adequate development was observed, evidencing the effectiveness of the aquaponic system for the cultivation of vegetables. The importance of maintaining optimal water quality parameters such as dissolved oxygen, pH and nutrient concentration to maximize the productivity of both crops is evident. This aquaponic system is presented as a viable and sustainable alternative for the integrated production of fish and vegetables, offering economic and environmental benefits. Further research with different species and scales of production is recommended to further optimize its performance.
