The largest companies in salmon aquaculture are rapidly getting bigger due to organic growth as well as mergers and acquisitions, and the largest are now multi-national companies. There are two main explanations for this growth: 1) An attempt to become large enough to exploit market power, or 2) Size is necessary to adopt new technologies that increase the efficient scale. In this paper, we investigate the degree of concentration in each of the main producer countries for Atlantic salmon, as well as globally for Atlantic salmon, all farmed salmon, and all salmon to account for the global nature of the market using Herfindahl-Hirschman Indexes. The results indicate a high degree of concentration in the smaller producer nations but not in Chile and Norway. Globally, the Atlantic salmon industry can be characterized as unconcentrated, and it becomes even more so when the supply of other farmed salmon and wild salmon is accounted for. Hence, the main motivation for the increased company size appears to be capacity to adopt new knowledge and technology.
