California Fish and Wildlife Journal, 2021 To inform management and conservation of the species, we investigated the distribution of anadromy and residency of steelhead/rainbow trout (Oncorhynchus mykiss) in the Eel River of northwestern California.

Foraging and metabolic consequences of semi-anadromy for an endangered estuarine fish. [PDF]
PLoS ONE, 2017 Diadromy affords fish access to productive ecosystems, increasing growth and ultimately fitness, but it is unclear whether these advantages persist for species migrating within highly altered habitat.

Individual patterns of anadromy determine the cost of salmon lice exposure in brown trout
EcosphereFacultative anadromous salmonids may alter migratory behavior to mitigate against detrimental infections of aquaculture‐derived salmon lice (Lepeophtheirus salmonis); however, this likely incurs negative growth and fitness consequences.

Recent Adaptation in a Threatened Salmonid Revealed by Museum Genomics. [PDF]
Mol EcolABSTRACT Steelhead/rainbow trout (Oncorhynchus mykiss) is an imperilled salmonid with two main life history strategies: migrate to the ocean or remain in freshwater. Domesticated hatchery forms of this species have been stocked into almost all California waterways, possibly resulting in introgression into natural populations and altered population ...

Population Genomics Provides Novel Insights Into Evolutionary Relationships and Local Adaptation of Two Ecotypes <i>Coilia nasus</i>. [PDF]
Ecol EvolBased on whole‐genome resequencing, we determined that the freshwater‐resident form (C. nasus taihuensis) is an ecotype of anadromous Coilia nasus, not a distinct subspecies. The two ecotypes diverged approximately 4.6 thousand years ago, coinciding with the formation of Tai Lake.

Stronger Parental Than Temperature Effects on Methylation in Juvenile Brown Trout (<i>Salmo trutta</i>). [PDF]
Ecol EvolWe investigated the persistence of early‐life temperature‐induced DNA methylation and the role of parental life history in shaping epigenetic patterns in juvenile brown trout. While early thermal conditions had limited long‐term effects, parental, especially maternal, life history exerted strong and functionally relevant influences on offspring ...

Contrasting Life History Characteristics Between Riverine and Lacustrine Anadromous Arctic Char (<i>Salvelinus alpinus</i>) in the Western Canadian Arctic. [PDF]
Ecol EvolFreshwater habitat characteristics are known to affect life‐history traits of migratory salmonids. Comparison of a riverine and lacustrine population anadromous Arctic char revealed significant tradeoffs in traits such as size, age, growth, maturity, migration, and mortality.

Global consequences of dam-induced river fragmentation on diadromous migrants: a systematic review and meta-analysis. [PDF]
Biol Rev Camb Philos SocABSTRACT The global proliferation of dams has altered flow and sediment regimes in rivers, presenting a major threat to freshwater biodiversity. Diadromous species, such as fishes, decapod crustaceans and gastropods, are particularly susceptible to fragmentation because dams obstruct their breeding migrations between coastal waters and rivers. Although

The origins and persistence of anadromy in brook charr [PDF]
Reviews in Fish Biology and Fisheries, 2010 We synthesized the results of a coordinated study examining the spatial and temporal movements, genetic structure, and physiological characteristics of sympatric populations of resident and sea-run brook charr across eastern Canada. Our goal was to critically evaluate three working hypotheses that may explain anadromous behaviour in brook charr: (1 ...
