Small anadromous Salvelinus malma at the southern limits of its distribution

Anadromy in the Dolly Varden Salvelinus malma at the southern limits of its distribution were examined by an intensive field survey and measurements of otolith Sr and Ca concentrations. Body sizes of anadromous individuals were small, only slightly larger than those of mature part, and the degree of anadromy was extremely low. (c) 2005 The Fisheries Society of the British Isles.
