In the last decades there have been significant changes in the retail sector resulting from globalization, the increased competitiveness and transformation on consumer's purchasing behaviour. This paradigm shift also applies to the fish sector, that has been capturing the interest of researchers internationally for political and economic reasons. Taking this competitive environment into account, which values the quality and the service given to the customer based on acceptable costs, it is necessary to adopt customer focused strategies. This thesis is integrated in the ValorMar's project, which was born from the commitment of a broad spectrum of entities, from companies to research centers, positioned by the relevance of the sea economy in the fishery value chain. Thus, this dissertation will try to understand critical relations for the decision making of customers when buying fresh fish.For this, transactional data and data mining techniques appropriate to the problem will be used. The methodology proposed by this thesis aims not only to identify customers using clustering techniques, but also to analyze the market basket of a fresh fish customer. These data analyzis will show that the knowledge extraction from large databases allows to improve the companies strategic decisions and their relationship with customers.
