The problems of the aquaculture industry Fish farming poses a
number of environmental challenges that need to be addressed for
the industry to be considered sustainable, and for consumers to
be able to buy farmed fish with confidence in its sustainable
credentials. One of the challenges is to find a source of food
to sustain fish in farms that does not solely depend on wild
fish being caught. Feeds have been developed with sustainability
in mind in recent years, but it still takes between 1.7kg and
4.9 kg (dependent on a number of factors) of wild caught fish to
produce 1kg of salmon. There are a number of other environmental
impacts associated with fish farming, such as pollution effects
on the seabed beneath and around a cage, diseases amongst stock
which can spread to wild populations, ecological effects of fish
that escape from fish farms, and from fish parasites and their
treatments. Please download the Principles and criteria for
sustainable fish farming that provides detailed solutions to the
