2.3. Data inventory
Data of the foreground system for 2009 and the first half of 2010
were gathered on-site in close collaboration with company staff
and the respective hatcheries. Results in this paper are represented
as the weighted average of the farms (based on the annual production
of the farms) and the weighted average of the hatcheries
(based on the annual total mass of fingerlings supplied to the
farms). Fig. 1 gives an overview of all identified flows in the foreground
system for which data were collected.
