There would appear to be considerable potential for Arctic charr, Salv
elinus alpinus (L.), to be cultured in marine conditions in countries
where coastal winter salinity is below oceanic, and temperatures remai
n above freezing. Sea lochs on the west coast of Scotland represent on
e such environment where freshwater run-off leads to depressed salinit
ies (20-30 practical salinity units) and the North Atlantic Drift lead
s to winter sea water temperatures typically around 6-8 degrees C.
