Strontium:calcium ratios in Atlantic salmon ( Salmo salar ) otoliths and observations on growth and maturation

In this paper, we report on two data sets that have relevance to contemporary ideas on maturation in Atlantic salmon (Salmo salar): (i) an analysis of maturity rate of Atlantic salmon captured in the southern Labrador Sea and (ii) a study of otolith strontium:calcium ratios for maturing and immature...
