Tilapicultura presents an important segment of social and economic development, considering the potential of natural resources in Brazil. The main contribution of this thesis is related to the management process in the main tilapia producing regions of the country, which is not just a question of generating economic indicators. Within this theme, as a proposal to measure an efficiency evaluation, through Data Envelopment Analysis (DEA analysis), the objective of this study was to evaluate the performance of the main poles producing tilapia in Brazil, in order to generate information that effectively contributes to actions aimed at efficiency gains and competitiveness in the productive sector, as well as to find the determinants of inefficiency through the Tobit econometric model. It observed that between the poles there was a variation between 41 and 85% of global efficiency, due to the characteristics of each region, as well as the management of the factors of production. Among the variables that had a positive influence on efficiency were the collective organization, technical assistance and technology adopted; in the same way, absence of technology, assistance, as well as indebtedness were pointed as negative variables to productive performance. It concluded that in the near future, the good manager would be represented by the greater productive efficiency, generating a reduction of its costs and improving its profits in market mishaps in which the producer is a price-taking agent, considering a competitive and growing scenario for national tilapia farming.
