Agriculture and Environment: Salmon

Environmental Impacts of Production: Ecological Footprint

A recent report by Michael Weber (1999) suggests that for every metric ton of Atlantic salmon from aquaculture, 10.6 hectares of marine area and 3.0 hectares of terrestrial area were required to support or provide the inputs to make it possible.
For example, some 99% of the marine requirement for production of salmon is dedicated to the production of organisms that are caught and made into salmon feed.

On the terrestrial side, some two-thirds of the land required was actually to assimilate the 7 metric tons of carbon dioxide created during the production of a metric ton of salmon from aquaculture. Most of the remaining terrestrial impacts resulted from the production of crops that were converted to salmon feed.
