Size-selective mortality occurs in smolts during a seaward migration, but not in river residents, in masu salmon (Oncorhynchus masou)
Salmonid fish often experience size-selective mortality when descending the river (i.e., seaward migration). However, it is unknown whether...

Balancing risks and rewards of alternate strategies in the seaward extent, duration and timing of fjord use in contemporary anadromy of brown trout (Salmo trutta)
BackgroundAnadromy comprises a successful life-cycle adaptation for salmonids, with marine migration providing improved feeding opportunities and...

Rates of Mainland Marsh Migration into Uplands and Seaward Edge Erosion are Explained by Geomorphic Type of Salt Marsh in Virginia Coastal Lagoons
Complexities of terrestrial boundaries with salt marshes in coastal lagoons affect salt marsh exposure to waves and sediments creating different...

Factors Affecting Fish Migration
Multiple environmental and endogenous elements work together to cause fish migrations. Abiotic and biotic environmental conditions, such as seasonal...

A new element in the migration cycle of the European river lamprey Lampetra fluviatilis: downstream migration from a lake
In 2019, during spring flood, we collected unusual Lampetra fluviatilis smolts migrating from a small lake, as part of a multi-year survey in the...

Freshwater early life growth influences partial migration in populations of Dolly Varden (Salvelinus malma malma)
Populations of northern Dolly Varden ( Salvelinus malma malma ) exhibit partial seaward migration, yet little is known about this phenomenon in Dolly...

Messenger RNA transcription levels of neuronal soluble N-ethylmaleimide-sensitive factor attachment protein receptor complex components in the olfactory nerve system of the anadromous Pacific salmon, masu salmon Oncorhynchus masou
Anadromous Pacific salmon (genus Oncorhynchus ) are known for homing behavior to their natal rivers based on olfactory imprinted memories during...

Partitioning survival during early marine migration of wild and hatchery-reared Atlantic salmon (Salmo salar L.) smolts using acoustic telemetry
The marine migration of Atlantic salmon ( Salmo salar ) has been prioritised for research internationally as populations of S. salar have declined...

Size-dependent growth tactics of a partially migratory fish before migration
In many migratory species, smaller migrants suffer higher mortality rates during the risky migration. To minimize the size-selective mortality,...

Diverse migration patterns of anadromous white-spotted charr Salvelinus leucomaenis revealed from otolith microchemistry
Anadromous migration of salmonid fish has been extensively studied, primarily focusing on the dichotomous framework of anadromy and residency....

Partial Migration in Salmonids: Focusing on Asian Endemic Masu Salmon (Oncorhynchus masou) and White-Spotted Charr (Salvelinus leucomaenis)
Partial migration is perhaps one of the most striking features of life-history polymorphism, in which a population displays both migratory and...

Gene expression levels of synaptic exocytosis regulator synaptophysin in the brain and the olfactory organ of anadromous salmon
Anadromous Pacific salmon (genus Oncorhynchus ) are known for their homing behavior based on olfactory imprinting, which is formed during their...

Combining fine-scale telemetry and hydraulic numerical modelling to understand the behavioural tactics and the migration route choice of smolts at a complex hydropower plant
Mitigation measures for downstream migratory Atlantic salmon smolts ( Salmo salar L.) at migration barriers usually turn out to be insufficient to...

Evidence of long-distance coastal sea migration of Atlantic salmon, Salmo salar, smolts from northwest England (River Derwent)
BackgroundCombining data from multiple acoustic telemetry studies has revealed that west coast England Atlantic salmon ( Salmo salar L.) smolts used...

Quantifying the effects of tides, river flow, and barriers on movements of Chinook Salmon smolts at junctions in the Sacramento – San Joaquin River Delta using multistate models
Successful migration of Chinook Salmon ( Oncorhynchus tshawytscha ) smolts seaward in the Sacramento – San Joaquin River Delta (hereafter, Delta)...

The effect of externally attached archival data loggers on the short-term dispersal behaviour and migration speed of European eel (Anguilla anguilla L.)
BackgroundExternally attached archival data logging tags are increasingly used to unravel migration routes of fish species at sea. Due to the...

Transcriptome analysis of the brain provides insights into the regulatory mechanism for Coilia nasus migration
BackgroundCoilia nasus ( C. nasus ) is an important anadromous fish species that resides in the Yangtze River of China, and has high ecological and...

What controls home range relocations by estuarine fishes downstream from watersheds with altered freshwater flow?
We tracked locations of three fish species in two bays with differing hydrology in SW Florida in 2018–2020 to test the hypotheses about fish...

Long-term monitoring of a brown trout (Salmo trutta) population reveals kin-associated migration patterns and contributions by resident trout to the anadromous run
BackgroundIn species showing partial migration, as is the case for many salmonid fishes, it is important to assess how anthropogenic pressure...

Na+/K+-ATPase Activity in Smolts of Pink Salmon Oncorhynchus gorbuscha (Walbaum, 1792) from the White Sea Exposed to Fresh, Estuarine, and Sea Water
AbstractThe Na + /K + -ATPase (NKA) activity in smolts of pink salmon Oncorhynchus gorbuscha (a salmon species introduced in 1959 into the rivers of the...
