Resorption of scales in Atlantic salmon (Salmo salar) during its anadromous migration: a quantitative study ...
Resorption processes in the scales of Atlantic salmon, during its anadromous migration are known since 1935, but have never been quantified. In fact, the ellipsoid form of the ascending salmon scale resorbs into an irregular highly deformed shape in spawning salmon. The aim of this study is to quant...

Resorption processes in the scales of Atlantic salmon, during its anadromous migration are known since 1935, but have never been quantified.
