Análise de viabilidade técnica e econômica de implantação de uma aquaponia no distrito de barra grande, Maraú-ba

Abstract

Meeting the growing demand of the population with healthy and sustainable food requires technological advancements, and this is becoming increasingly evident. Aquaponics systems have been showing excellent results, as they not only generate income but also serve as a diversified cultivation activity, ensuring food and nutritional security, in addition to the well-known environmental benefits. The present study aims to assess the technical and economic feasibility for a future investment in an aquaponics system for growing vegetables (lettuce and scallions) in conjunction with the production of Nile tilapia in the district of Barra Grande, Maraú – BA. The methodology adopted in this study is based on aquaponics system procedures and technical and economic analysis based on production costs. The project consists of 4 thousand-liter water tanks for Nile tilapia production and 2 hydroponic benches for lettuce and scallion production. The planning includes weekly harvesting of vegetables, ensuring the project's cash flow, and fish cycles according to the region's seasonality, planning for more harvests during the summer. The integrated system of Nile tilapia production with vegetable production in an aquaponic system showed a total revenue of R$ 123,836.38 and a total cost of R$ 96,624.33, resulting in a positive balance of R$ 27,212.05, generating a net income or operational profit of 21.97% of revenue. From an economic perspective, the project proved to be viable, with an annual revenue exceeding its costs and generating profit. In this way, it meets the market demand for healthy and clean food that does not degrade the environment and is free of pesticides.
