Resumption of Anadromy or Straying? Origins of Sockeye Salmon in the Elwha River
Transactions of the American Fisheries Society, 2021AbstractWhen barriers to migration are removed, anadromous fishes from other rivers may colonize newly accessible habitat or landlocked forms of the species may resume anadromy if conditions allow. For example, two large hydroelectric dams on the Elwha River, Washington, were removed between 2011 and 2014 to restore populations of Pacific salmon ...

The Genomic Consistency of the Loss of Anadromy in an Arctic Fish (Salvelinus alpinus)
The American Naturalist, 2022AbstractThe potentially significant genetic consequences associated with the loss of migratory capacity of diadromous fishes that have become landlocked in freshwater are poorly understood. Consistent selective pressures associated with freshwater residency may drive repeated differentiation both between allopatric landlocked and anadromous populations

Evidence for anadromy in a southern relict population of Arctic charr from North America
Journal of Fish Biology, 1999Stable isotope analysis of Arctic charr from a southern relict population in Québec showed that some individuals adopted anadromy as a life‐history strategy, but the strategy did not predominate in the population. Differences in length‐at‐age, ages and sex ratios between identified freshwater residents and anadromous individuals were consistent with ...

On the problem of ratio of anadromy and residence in salmonids (Salmonidae)
Journal of Ichthyology, 2008According to published and original data, the anadromy and residence in salmonids (Salmonidae) are considered: within one population; in males and females; in different populations in the area of one species under natural conditions; outside of the natural area, at introduction; types of anadromy and residence in different species; causes and ...

Assessing anadromy of brook char (Salvelinus fontinalis) using scale microchemistry
Canadian Journal of Fisheries and Aquatic Sciences, 2006Brook char (Salvelinus fontinalis) exist in both freshwater and anadromous forms, often in sympatry, the ecology of the latter being poorly understood. As strontium (Sr) can substitute to calcium (Ca) and as its concentration in seawater is higher than in freshwater, scale circulii laid down during seawater exposure should be enriched in Sr, allowing ...

To Sea or Not to Sea? Anadromy Versus Non-Anadromy in Salmon ids
2003Abstract “Migration” has been defined in many ways that have a variety of connotations (Endler 1977; Dingle 1996). Here we follow Endler (1977) in considering migration to be “relatively long-distance movements made by large numbers of individuals in approximately the same direction at approximately the same time ...usually followed ...

Movement of Resident Rainbow Trout Transplanted below a Barrier to Anadromy
Transactions of the American Fisheries Society, 2012AbstractWe tracked the movement of resident coastal rainbow trout Oncorhynchus mykiss irideus that were experimentally transplanted below a migration barrier in a northern California stream. In 2005 and 2006, age‐1 and older rainbow trout were captured above a 5‐m‐high waterfall in Freshwater Creek and individually marked with passive integrated ...

Anadromy and the marine migrations of Pacific salmon and trout: Rounsefell revisited
Reviews in Fish Biology and Fisheries, 2004Anadromy is a defining trait in salmonid fishes but it is expressed to different extents among the species in the family, as reviewed in a classic paper by Rounsefell (1958). The present paper re-examines the subject, assessing the degree of anadromy within the genus Oncorhynchus, using Rounsefell’s six criteria: extent of migrations at sea, duration ...
