Loss of Global Animal Protein
As salmon are carnivores, the energy and protein conversion (the
amount of feed that is required to produce a farmed salmon) is a concern.
Although there have been very
positive developments in increasing feed efficiency, it is important to
consider how many wild fish are required to make up the fishmeal and where
these fish are coming from. More than one tonne of wild fish are needed to make
up the feed for one tonne of farmed salmon,[1] and these
"feeder fish" often come from developing countries. This is not a sustainable practice and taxes the fisheries
of countries supplying fishmeal.[2],
