The growth of a Welsh strain of Arctic charr Salvelinus alpinus (L.) and investigations into its aquaculture potential

Abstract

The growth in captivity of a wild Welsh strain (Llyn Cowlyd) of Arctic charr (Salvelinus alpinus) was compared to that of a commercial Scottish strain over the course of a 12 month experiment. At the conclusion of the study, the Welsh strain had a lower mass and condition factor than the commercial fish, but a similar length. Aspects of the growth and population structure of the Welsh strain imply that it could be a subject for aquaculture development, but such practises will be dependant on further work on selection and broodstock development.
