Market concentration in the Spanish turbot aquaculture sector: A regional analysis

This paper analyses the regional evolution of the market structure in the Spanish turbot industry, which is the leading turbot producer in Europe, using different concentration rates. The analysis is performed considering several factors that have influenced the evolution of the sector, the most important being the application of technology, business strategies and the institutional framework. The results confirm a process of concentration. Starting from an initial phase in which the sector was composed of a considerable number of small companies, this industry has evolved towards a situation in which only two large firms dominate the market.
