Desempenho econômico e ambiental da produção do camarão Litopenaeus Vannamei em sistema de bioflocos

Abstract

In a scenario of excessive exploitation of fisheries resources and environmental degradation, modern aquaculture has been gaining importance and taking the form of an environmentally correct and nature-friendly activity. In this context, the intensive and superintensive production of marine shrimp in a biofloc system stands out, in economic and environmental terms, for its productivity and rational use of natural resources. However, there are still few scientific studies that compare its environmental and economic performance, which are relevant to the development of a sustainable aquaculture. In order to verify and compare the bioeconomic viability of intensive production in nurseries and superintensive in greenhouses, in a system with bioflocs, of the shrimp Litopenaeus vannamei, this study proposes to carry out an environmental and economic analysis of the two production systems. For this, traditional investment analysis techniques will be used (Net Present Value - NPV, Annual Equivalent Value – VAE, Payback - PB, Discounted Payback - PBD, Profitability Index - IL, Internal Rate of Return - TIR, Modified Internal Rate of Return – TIRM), risk analysis (Monte Carlo simulation) and environmental performance, using Life Cycle Assessment (LCA). The results of the study provide decision makers with environmental and economic subsidies that can assist in decision making regarding investment in the activity, as well as provide consumers with information on the environmental performance of the product and its impact on the environment.
