S.  aRegional analysis of aquaculture value chainbStudy of tilapia production zones in Brazil.h[electronic resource]  c2022  aThis study provides a broad discussion on the tilapia culture chain in Brazil. It aims to analyse the business environments of tilapia culture zones in Brazil, supported by the Global Value Chain (GVC) approach. For this purpose, this study used a wide range of multidimensional indicators collected from tilapia production units (TPUs) and distributed in four selected and categorised production zones (TPZs). Based on fuzzy modelling, this analysis was carried out by comparing multidimensional indexes of business environments estimated by a fuzzy inference system. The research concluded that more verticalized governance models are more promising for the development and internationalisation of the chain in Brazil. It also concluded that in productive arrangements where these forms are not fully dominant, the regional role of competent suppliers, associated with active technical assistance, could play a key role for technological development at the TPU level. However, it points out that the coordination of fish farmers in the value chain should take into account regional aspects, and alternative forms of verticalization. Additionally, it was highlighted that the synergy of this chain with other more internationalised agri-food segments, such as poultry and pork, can be a key element in overcoming future obstacles arising from a global integration process. Moreover, the main configurations and barriers faced by each productive zone in the current scenario and the challenges related to an eventual institutional upgrading necessary to meet international marketing standards are also highlighted. Finally, the study proposes a research agenda that expands the range of quantitative and micro studies in the field of GVC, seeking to better understand, from multiple perspectives and scopes, the possible effects and results associated with the internationalisation of the aquaculture chains of the Global South.  aBusiness organization  aFuzzy logic  aGovernance  aResearch institutions  aAquicultura  aCadeia Produtiva  aPeixe  aProdução  aTilápia  aBusiness environmental index  aFirm-level analysis  aFuzzy inference system  aUpgrading1 aPEDROZA FILHO, M.
