Aquaponia e peixes ornamentais: possibilidade real

Abstract

In this literature review we present the state of the art of aquaponics and propose an innovative integration with ornamental fish. Aquaponics is a cultivation system that combines aquaculture (cultivation of aquatic organisms) and hydroponics (cultivation of plants without the use of soil, with roots submerged in water). The feed waste dissolved in the water is rich in nutrients that, when converted by bacteria, nourish the plants, and this filter the water for the fish. This possibility seeks to reduce environmental wear in relation to the growing production of food to meet the demand for population growth. The fish used in aquaponics are generally consumed. So, we bring another perspective, is aquaponics and ornamental fish a real possibility? To answer, we present a feasibility analysis of a hypothetical system, which resulted in an IRR of 7% and a NPV of R$ 805.47 making the project viable in this respect. In addition, there is still a social aspect, since it is to serve a family space, strengthening the maintenance of men in the countryside.
