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

Impact of Environmental Conditions on the Spawning Migration of Sea Trout (Salmo trutta L.) in Two Large, Sub‐Arctic River Systems

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 ...

Genetic and Ecological Management of Pacific Salmon Fisheries for the 21st Century

Fisheries Management and Ecology, EarlyView.
ABSTRACT Based on ecological adaptation theory, tremendous effort is being spent on measures that are eliminating salmon hatcheries and fishing opportunities with the intention of protecting wild runs deemed to be of particular genetic importance to the survival of the species.

Decadal Rapid Change in Energetic Carrying Capacity for Juvenile Chum Salmon in the Sanriku Coast

Fisheries Oceanography, EarlyView.
ABSTRACT Adult returns to coastal rivers in Sanriku, located near the southernmost area of chum salmon distribution, have declined since 2010. Climate‐induced fluctuations in juvenile prey availability may affect growth and survival, which are linked to adult returns.

The first finding of sockeye salmon Oncorhynchus nerka (Walbaum) in the Bolshaya River on Zavyalov Island

Известия ТИНРО, 2022
The sockey salmon entry to the Bolshaya River on Zavyalov Island in the northern Okhotsk Sea was registered for the first time on July 26, 2021. Larger specimens were observed among the pink salmon going to spawn in this river, and one of them was caught

Using the Diet Composition of Adult Chinook Salmon to Understand the Regional Structure of Salish Sea Forage Communities

Fisheries Oceanography, EarlyView.
ABSTRACT Small pelagic fish and other forage species are patchily distributed over space and time, resulting in variable foraging conditions experienced by their predators. The high‐resolution data necessary to understand the spatiotemporal structure of forage communities are challenging to collect with expensive fishery‐independent surveys, meaning ...

Genes, fish and fisheries: translating science into policy

Journal of Fish Biology, EarlyView.
Abstract The 2024 Annual Symposium of the Fisheries Society of the British Isles reviewed the burgeoning impact of ‘omics’ technologies on fish ecology, management and forecasting. As with life sciences more generally, major advances in speed, cost‐effectiveness and breadth of applications in ‘omics’ has had profound societal and environmental impacts.

Phenology and Fraser River sockeye salmon marine survival

Progress in Oceanography, 2021
Abstract Inspired by the pioneering work of Dr. Bill Peterson who demonstrated the utility of ocean indicators at predicting survival of coho and chinook salmon in the Columbia River, we investigated whether the phenology of primary productivity could explain variable marine survival of Fraser River sockeye salmon.

Bull trout (Salvelinus confluentus) exhibit binge‐feeding and digestive flexibility during seasonal resource pulses associated with salmon migrations

Journal of Fish Biology, EarlyView.
Abstract Resource pulses are infrequent, ephemeral events of resource hyperabundance that can represent important feeding opportunities for consumers. To capitalize on pulsed resources, consumers can exhibit behavioural and physiological traits including binge‐feeding and phenotypic plasticity of digestive physiology, although expression of these ...

Intrapopulation differentiation of sockeye salmon Oncorhynchus nerka of the lake-river systems on eastern coast of Kamchatka

Известия ТИНРО, 2015
Intrapopulation differentiation of the two large population systems of sockeye salmon from the Kamchatka and Apuka Rivers in East Kamchatka is considered by analysis of 45 SNP loci.
