To this end, the research scope has been narrowed to fish supply chain that has been analyzed in dept. At first, data about products flowing along the supply chain have been collected; due to the strong influence they have in the structure of the supply chain. In particular fish can be classified by its origin/production into farmed fish and fished fish or can be also classified according to its storage conditions into fresh fish and frozen fish. Such classifications are very important, since they affect the supply chain management and the very nature of its operational processes.
