Adult returns to many Atlantic salmon wild and hatchery stocks of the North Atlantic have
declined or collapsed since 1985. Enhancement, commercial fishery closures, and angling …

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 …

Atlantic salmon populations have declined in recent decades. Many of the threats to the
species during its freshwater and coastal residency periods are known, and management …

A major challenge in understanding the response of populations to climate change is to
separate the effects of local drivers acting independently on specific populations, from the …

The parr–smolt transformation of anadromous salmonids is a suite of behavioral,
morphological, and physiological changes that are preparatory for downstream migration …

Migrations between different habitats are key events in the lives of many organisms. Such
movements involve annually recurring travel over long distances usually triggered by …

The expansion of salmonid aquaculture has resulted in environmental challenges, including
salmon lice that may infest both farmed and wild fish. For wild Atlantic salmon post-smolts …

Atlantic salmon Salmo salar is a socio-economically important anadromous fish species that
has suffered synchronous population declines around the North Atlantic over the last five …

The salmonid lifecycle has been studied for over a 100 years. Our literature search indicated
that the Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) are among the most …

Parasites can, in theory, have large impacts on the survival of fish populations. One method
to evaluate such impacts on anadromous species is to apply manipulative field experiments …
