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.  

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.

Invasive pink salmon eat what they find; fish larvae, amphipods, krill, like Atlantic salmon, but so far abundance is too low to expect competition in the ocean. Local impacts by pink salmon on coastal ecosystems cannot be ruled out.
