Tilapia is one of the fastest growing aquaculture species in the world. It is produced and consumed in all continents and in more countries than most other species, making the market more heterogeneous than for other successful aquaculture species such as salmon and shrimp. This paper investigates the degree of market integration between tilapia from the three largest production regions, Asia, Africa and South and Central America. We consider differences in the production methods, transport costs and qualities of these regions and determine whether tilapia products from different producers can essentially be considered the “same” product. This is important if the rapid worldwide development of farmed tilapia and its future development prospects are to be better understood.
