Migrating marine taxa encounter diverse habitats that differ environmentally and in foraging conditions over a range of spatial scales. We examined body (RNA/DNA, length-weight residuals) and nutritional (fatty acid composition) condition of juvenile ...

Sockeye salmon of Russian origin: what can fishermen сount on?
Information on dynamics of abundance for sockeye salmon of Russian origin is presented, with assumptions on prospects of this species fishery in the future decade. The average annual catch in the period from 1907 to 2022 was about 27 thousand tons.

Coliform Flora of Migrating Sockeye Salmon (Oncorhynchus nerka)
The coliform flora of migrating sockeye salmon (Oncorhynchus nerka) was examined at two marine and one freshwater location. Enterobacter species accounted for approximately 50% of all isolates; the remaining isolates were divided almost equally between ...

Recent ecological divergence despite migration in sockeye salmon (Oncorhynchus nerka). [PDF]
Ecological divergence may result when populations experience different selection regimes, but there is considerable discussion about the role of migration at the beginning stages of divergence before reproductive isolating mechanisms have evolved.

Under-Ice Diel Vertical Migrations of Oncorhynchus nerka and Their Zooplankton Prey
We used stationary hydroacoustics and measures of environmental conditions (water temperature, dissolved oxygen, light levels, and zooplankton) to determine what factors, foraging or predation risk, influenced diel vertical migrations of Oncorhynchus ...

Olfactory responses to natal stream water in sockeye salmon by BOLD fMRI. [PDF]
Many studies have shown that juvenile salmon imprint olfactory memory of natal stream odors during downstream migration, and adults recall this stream-specific odor information to discriminate their natal stream during upstream migration for spawning ...

The variability of an MHC complex gene in sockeye salmon populations throughout the Asian range was studied to identify “footprints” indicative of pathogen-mediated selection and neutral demographic processes that have influenced these populations in ...

Prey group cohesion mediates the outcome of predator–prey interactions under artificial lighting
Read the free Plain Language Summary for this article on the Journal blog. Abstract The highest rates of piscivorous predation in the field have been recorded during crepuscular light levels associated with sunrise and sunset or artificial lighting at night (ALAN).

The complete mitochondrial genome sequencing of Anisakis simplex isolated from Anoplopoma fimbria
In this study, zoonotic Anisakis simplex was isolated and identified from the outermost layer of the stomach of diseased Anoplopoma fimbria at an industrial farm in Liaoning, North China (122.1842 E, 39.2616 N). With the completion of A.

ABSTRACT The global decline in salmonid stocks has increased the need for knowledge of local adaptations and life history strategies of salmonids. In this study, we used radio‐telemetry tracking data from sea trout populations in two large high‐latitude rivers to model upstream spawning migration speed of trout in response to prevailing environmental ...
