This paper analyses the organisation of the post-harvest Nile perch supply chain centred on Lake Victoria in East Africa to test the practical relevance of the market-driven supply chain thesis proposed by Folkerts and Koehorst (1998). It finds that while international consumer demand, particularly in demanding improved quality standards according to HACCP principles, is having profound local organisational ramifications, the evolving supply chain is presently best characterised as being a hybrid one - neither exclusively production, nor marketdriven.
