Sockeye salmon of Iturup Island: characteristics of spawners from commercial catches in 2021
Известия ТИНРО, 2022 Spawners of sockeye salmon caught in northern Iturup and in the Prostor Bay and Kurilsky Bay in July-August, 2021 are investigated. Almost all of them had the age 1.2+ or 1.3+, with prominent prevalence of the former both for females (88.9 %) and males ...

Feeding habits of pacific salmons in the eastern Bering Sea in 2003-2012
Известия ТИНРО, 2015 Change in prey for pacific salmons in the eastern Bering Sea is considered between the periods of relatively warm (2003-2006) and relatively cold (2007-2012) conditions on the base of data obtained in the frames of BASIS research program.

Remote Sensing in Ecology and Conservation, EarlyView.Drones and computer vision offer an efficient way to estimate animal populations over localized areas, but surveys often require stitching many overlapping images together. If animals move during the survey, traditional orthomosaic‐based counting methods become unreliable, with some animals appearing in multiple locations while others appear not at all,

Prey group cohesion mediates the outcome of predator–prey interactions under artificial lighting
Functional Ecology, EarlyView.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).

Fisheries Management and Ecology, EarlyView.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 ...

Contrasting Food Web Dynamics Across Oceanographic Boundaries in Subarctic Pelagic Ecosystems
Fisheries Oceanography, EarlyView.ABSTRACT Understanding the structure of pelagic food webs across multiple trophic levels is critical for elucidating species interactions, energy flow, and anthropogenic impacts on production. This study presents a comprehensive analysis of the eastern North Pacific pelagic food webs, focusing on the Gulf of Alaska (GoA) during late winter of 2019.

Juvenile salmon usage of the Skeena River estuary.
PLoS ONE, 2015 Migratory salmon transit estuary habitats on their way out to the ocean but this phase of their life cycle is more poorly understood than other phases. The estuaries of large river systems in particular may support many populations and several species of
