Salmon farming increases the abundance of salmon lice, which are ectoparasites of
salmonids in the sea. Here we review the current knowledge on the effects of salmon lice on …

Sterilization by triploid induction prevents interbreeding between escaped farmed salmon
and wild stocks, but reduced performance of triploids at high seawater temperatures has …

Decreased marine survival is identified as a component driver of continued declines of
Atlantic Salmon Salmo salar. However, estimates of marine mortality often incorporate loss …

Host–parasite interactions are moderated by the environmental conditions of the interaction
medium (eg air or water). Encounter rate and the time available for a parasite to make …

The abundance of alewife (Alosa pseudoharengus) and blueback herring (Alosa aestivalis)
has declined throughout their range, and there are increasing concerns about their …

Timing of ocean entry is critical for marine survival of both hatchery and wild Atlantic salmon
(Salmo salar) smolts. Management practices and barriers to migration such as dams may …

Little information has been gathered regarding the ontogenetic changes that contribute to
differentiation between resident and migrant individuals, particularly before the onset of …

For semi‐anadromous brown trout, the decision whether or not to smoltify and migrate to the
sea is believed to be made at the end of the preceding summer in response to both local …

Abstract Knowledge of swimming depths and migration routes of homing Atlantic salmon in
open coastal zones is urgently required to inform decisions on managing the species, eg for …

Chum salmon (Oncorhynchus keta) migrate to the ocean in their first spring, and growth
during early marine life is critical for survival. We examined the validity of circulating IGF-I …
