Assessment of winter size‐selective mortality of young‐of‐the‐year Atlantic salmon ( Salmo salar ) using otolith microstructure analysis*
Abstract – The objectives of this study were, first, to assess the usefulness of otolith microstructure analysis to examine winter size‐selective mortality of young‐of‐the‐year (YOY) Atlantic salmon and, secondly, to validate various hypotheses relating to the dynamics of two populations with differ...
