“…Etne salmon must pass through the Hardangerfjord during migration, an area of intensive farming activity since the 1990s, resulting in increased infestation pressures to wild populations (Serra‐Llinares et al., ). Landlocked salmon (for ecology, see Lumme, Ozerov, Veselov, & Primmer, ) and wild salmon eggs were collected from wild parents from their natal rivers and transferred to the Institute of Marine Research Matre Research Station, Norway, for hatching. Fish were raised in the same tank environment experienced by domesticated salmon, using standard husbandry protocols.…”

Atlantic salmon populations across the world have diverse ecological and evolutionary histories, from wild anadromous or landlocked, to domestication and genetic modification. The natural host behaviours confer protection from infestation by ectoparasitic salmon lice Lepeophtheirus salmonis, yet whether genetic origin results in different behaviours and thus susceptibility to infestation is unknown. In common garden experiments, we tested antiparasite behaviours, susceptibility and retention of salmon lice in wild anadromous, wild landlocked, domesticated and genetically modified domesticated strains. Within domesticated strains, we tested two infestation histories (previously infested and naïve) and a new phenotype (albino colouring). Farmed stocks initially acquired 24%-44% higher levels of parasite density than the wild and landlocked strains. Burst swimming and displacement behaviours were higher in the domesticated groups, and jumping was more prevalent in the domesticated strains. At 34 days post-infestation, domesticated strains and the wild anadromous strain did not differ significantly from each other; however, landlocked salmon had increased infestation levels considerably. Domesticated strains lost ~20% (±9.9%-16.5%; 95% CI) of their initial parasite load, while parasite load increased by 5.5% (±30.1%) for wild salmon and 20.1% (±28.5%) in landlocked salmon. This study provides early evidence for diverged host-parasite interactions associated with domestication in this system.

“…1). Given that distributional details are provided elsewhere (MacCrimmon and Gots 1979;Kazakov 1992;Webb et al 2007;Lumme et al 2016), only an overview is provided here. On mainland Canada, the greatest geographical spread of ouananiche is in Québec, where the life-history form is distributed throughout the province (www.pourvoiries.com/en/fishing-quebec/species/ landlocked-salmon/).…”

“…Although the sizes attained by landlocked salmon have been known for some time (e.g., Chambers 1896;Kendall 1935), there are no compilations of life-history data for nonanadromous S. salar, notwithstanding one limited attempt (Hutchings 2002). Research has tended to focus on variability in life cycles (rather than life histories), migration patterns (e.g., Webb et al 2007;Lumme et al 2016), and descriptive data summaries to document population status (e.g., Runnström 1940;Wiseman 1971aWiseman , 1971bWiseman and Whelan 1974). Several studies have also examined various aspects of the population genetics of nonanadromous Atlantic salmon (e.g., Vuorinen and Berg 1989;Verspoor et al 1999;Säisä et al 2005;Perrier et al 2014;Hauge et al 2016).…”

“…This is particularly true in Newfoundland at present. However, for other populations, anadromy became increasingly problematic thousands of years ago when glaciers retreated, rates of isostatic rebound were high, and many nonanadromous salmonid populations were initially formed (Yesner et al 1984;Berg 1985;Lumme et al 2016), as access to and from the sea became improbable or impossible. In Québec and Newfoundland, where most of the world's nonanadromous S. salar populations are located, landlocked salmon are termed "ouananiche" (Chambers 1896).…”

Nonanadromous Atlantic salmon (Salmo salar) exhibit a combination of variation in life history, habitat, and species co-existence matched by few vertebrates. Distributed in eastern North America and northern Europe, habitat ranges from hundreds of metres of river to Europe’s largest lakes. As juveniles, those with access to a lake usually migrate to feed and grow prior to reproduction. Prey such as smelt (Osmerus mordax, Osmerus eperlanus) and vendace (Coregonus albula) facilitate large body size (50–85 cm at maturity) and persistence in high-diversity (>20 fish species) environments; small-bodied salmon (10–30 cm at maturity), relying on insects as prey, coexist with few (fewer than five) other fishes. At maturity, weight varies more than 400-fold (17 to 7200 g) among populations, fecundity more than 150-fold (33 to 5600), and longevity almost fivefold (3 to 14 years). Landlocked salmon are managed to support sustainable fishing, achieve conservation and restoration targets, and mitigate threats; successes are evident but multiple challenges persist. Extraordinary variability in life history coupled with extensive breadth of habitat and species co-existence render landlocked Atlantic salmon singularly impressive from a biodiversity perspective.
