To meet the growing demand for sustainable aquaculture, the biofloc technology (BFT) system has emerged as a promising solution, offering high productivity, improved water use efficiency, and enhanced environmental and biosecurity performance. Economic and risk analyses are essential tools for identifying the key technical and economic factors that determine the profitability and long-term sustainability of aquaculture systems. This study aimed to evaluate the economic feasibility and the risk associated with Nile tilapia juvenile production in a BFT system. Economic viability indicators were calculated using real data on capital investment, operational costs, and zootechnical performance from a production cycle. Scenario analyses were conducted to assess the effects of fluctuations in input prices and survival rates on overall economic outcomes. Stochastic simulations were also conducted to determine the probabilities of economic results. The items with the greatest impact on costs were the acquisition of the greenhouse and fingerlings, representing 27.64% of the initial investment and 33.24% of the operating cost, respectively. The BFT system showed a positive net margin and profitability per production cycle, with the exception of the pessimistic scenario. The risk analysis demonstrated that in 87.29% of the simulations resulted in a positive profit. Thus, the production of tilapia juveniles in a BFT system is an economically viable investment. However, its success is contingent upon specific technical and market conditions, underscoring the need for careful management and context-specific planning. Full article

The Green Agenda is a priority of the European Union. The development of environmentally friendly economic activities is high on the agenda of the EU institutions. Aquaculture is presented as an alternative activity to traditional fishing. For this reason, European funds have been allocated to promote aquaculture in the EU. The Court of Auditors of the EU has carried out the first complete audit on the efficiency of the financial resources received by the countries. This article analyzes the strengths and weaknesses of the aquaculture sector, the conclusions of the European Court of Auditors, and the main changes to be undertaken in the future. The reports conducted thus far are insufficient to establish measurable results. Additionally, these audits should be coordinated more effectively in terms of objectives and work plans to generate relevant data for the design of a European aquaculture policy that adequately addresses the sector’s needs.
