ABSTRACT THE sea-ward migration of the salmon (_Salmo salar_) which coincides with the parr-smolt transformation, involves the solution of important osmotic and mineral regulation problems
by the fish. The lack of tolerance for salt water at the parr stage has been noted previously1. However, neither the capacities for mineral regulation of this stage nor their probable shift
in the smolt have been subjected to an analysis, made more desirable by the fact that, like the endocrinological changes which occur at the same time2, they may be causally connected with
migration itself3. Access through your institution Buy or subscribe This is a preview of subscription content, access via your institution ACCESS OPTIONS Access through your institution
