The mortality of Arctic charr, Salvelinus alpinus , previously grown‐on in salt water during the summer months, was studied during the winter 1980–81. Mortality did not appear to be related to a‘ critical size‘ but rather to rates of growth shown by the fish during the summer months. Mortality was high amongst the slow‐growing fish. The results are discussed in relation to published data on the osmoregulatory capabilities of Salvelinus spp.
