Atlantic salmon (Salmo salar) is one of the best researched fishes, and its aquaculture plays
a global role in the blue revolution. However, since the 1970s, tens of millions of farmed …

Interactions between domesticated escapees and wild conspecifics represent a threat to the
genetic integrity and fitness of native populations. For Atlantic salmon, the recurrent …

Populations may counteract lasting temperature changes or recurrent extremes through
plasticity or adaptation. However, it remains underexplored how outbreeding, either …

Domestic animals are ubiquitous. In contrast to the biodiversity crisis currently impacting
many kinds of animals and plants, not a single domesticated species is endangered …

Abstract Background In Atlantic salmon in the wild, age at maturity is strongly influenced by
the vgll3 locus. Under farming conditions, light, temperature and feeding regimes are known …

Farmed fish are typically genetically different from wild conspecifics. Escapees from fish
farms may contribute one-way gene flow from farm to wild gene pools, which can depress …

Domesticated Atlantic salmon grow much faster than wild salmon when reared together in
fish tanks under farming conditions (size ratios typically 1: 2–3). In contrast, domesticated …

Despite the key role that sex-determination plays in evolutionary processes, it is still poorly
understood in many species. In salmonids, which are among the best studied fishes, the …

Domestication leads to changes in traits that are under directional selection in breeding
programmes, though unintentional changes in nonproduction traits can also arise. In …

Reproductive success and offspring survival until sexual maturity are essential traits both for
fish fitness and aquaculture development. Variation in offspring's survival among family …
