Study goals
To evaluate the economic viability of semi-intensive tilapia production in the western border region of Rio Grande do Sul, based on a technical simulation of one hectare of ponds, considering costs, revenues, and financial performance indicators.
Relevance / originality
The study contributes to addressing the lack of regional economic analyses applied to aquaculture, providing updated and locally adapted information essential for supporting investment decisions, professional management, and public policies focused on the aquaculture sector.
Methodology / approach
A quantitative methodology was applied, using secondary data and technical parameters representative of the region. Fixed and variable costs, revenues, reserves, and profitability indicators were estimated through a simulation of an eight-month production cycle in earthen ponds.
Main results
The system showed positive operating profit, a 26,96% margin over effective expenses, and the ability to cover both cash and non-cash costs. Feed accounted for 66,55% of variable costs, highlighting the need for cost-reduction strategies to improve profitability.
Theoretical / methodological contributions
The article emphasizes the importance of including non-cash costs in economic assessments, enhancing models for evaluating the economic viability of aquaculture systems with intensive structures and high input dependency.
Social / management contributions
It provides practical insights for decision-making by producers, technicians, researchers, entrepreneurs and public managers, promoting the use of financial planning and control tools. It also suggests strategies to improve production efficiency and ensure long-term economic sustainability in aquaculture.
