Abstract
This study aims to evaluate a particular property in Brasília that uses the aquaponics system on a small production scale. The Monte Carlo method was used to estimate its financial feasibility and the probability of the production volume and, consequently, evaluate the risk of this undertaking. The data analyzed included fixed and variable costs, revenues and financial viability indicators, which are net present value (NPV), periodic economic benefit (PEB) and internal rate of return (IRR). It was identified in this research that the cost with the largest participation was the land acquisition, amounting to more than 60%. According to the survey, the venture showed a 56.69% probability to generate a NPV, PEB and IRR rate, respectively, of R$ 117,784.26, R$ 16,003.11 and 37%. The probability of occurrence of fish volume and plant production were, respectively, 1179.44 kg and 731.26 kg with 74.43% and 76.16%, presenting a probability greater than 50%, which is considered as more reliable than traditional analysis. Therefore, we can conclude that it is economically viable according to the NPV parameters, which was greater than zero, and the IRR, that was higher than the minimum rate of attractiveness.

The experiment was carried out in a randomized block design with 3 x 1 factorial scheme, comprising three different densities of tilapia fingerlings, T1 (72): 72 fish / m3, T2 (144): 144 fish / m3 and T3 (216): 216. fish / m3 and one crop of basil for each tank, where each treatment continued for 45 days and replicated twice in a recirculating aquaponic system
Summary
Aquaponics is an integrated aquaculture system (cultivation of aquatic organisms) with hydroponics (cultivation of plants without the use of the soil). The system can be deployed in adverse climatic conditions, be it in the cold, the heat, places where there is water shortage and where there is soil contamination and water that are toxic to aquatic and plant organisms. Most studies are limited to demonstrating only the technical feasibility and to analyze the productive performance of a certain species of plant and fish in the Aquaponics system. In this context, the objective was to analyze the financial viability of an aquaponics enterprise installed at Pine Tree Farm, located in Brasilia, Distrito Federal, Brazil
