2.1. Scope definition
A case study has been performed according to the ISO 14040/
14044 guidelines (ISO, 2006a; ISO, 2006b), with one of the top
Vietnamese exporters of Pangasius food products (under the condition
of anonymity). The company is located in the Mekong Delta
and is vertically integrated (excluding the hatchery phase), meaning
that juvenile fish purchased from specialized hatcheries are
cultured at the company’s farming sites with feed manufactured at
the company’s feed mill, after which the harvested fish are transferred
to the company’s processing facility for filleting, freezing and
packaging.
