The diet of nearly six hundred salmon post-smolt caught in Norwegian fjords was analysed in a new study. Already at that early stage of the marine migration, it is important for the salmon to find fish larvae to feed on.  

Iteroparity and its contribution to life-history variation in Atlantic salmon

New study of iteroparity, or repeat spawning, of Atlantic salmon in 179 rivers shows that the proportion of repeat spawners averaged 3.8% (0-26% across rivers). Females were more often repeat spawners than males and lost less body mass between each spawning.
