Links between fluctuations in sockeye salmon abundance and riparian forest productivity identified by remote sensing

open access: yesEcosphere, 2021
Pacific salmon (Oncorhynchus spp.) carcasses can fertilize riparian forests with marine‐derived nutrients when populations make their annual return to natal streams to spawn; however, the strength of this cross‐system linkage likely varies substantially ...

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

open access: yesFisheries 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 ...

Effects of starvation on energy density of juvenile chum salmon (Oncorhynchus keta) captured in marine waters of Southeastern Alaska [PDF]

open access: yes, 2010
We conducted laboratory starvation experiments on juvenile chum salmon (Oncorhynchus keta) captured in the neritic marine waters of northern Southeast Alaska in June and July 2003. Temporal changes in fish energy density (whole body energy content [WBEC]

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

open access: yesFisheries 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.

Gravel galore: Impacts of clear-cut logging on salmon and their habitats [PDF]

open access: yes, 2002
Timber harvest may have both direct and indirect effects on salmon, and with a few exceptions those effects result in lowered survival of salmon in their stream habitats compared with unlogged forest (Hicks et al. 1991b).

Chemical composition and quality loss during technological treatment in coho salmon (Oncorhynchus kisutch) [PDF]

open access: yes, 2011
Coho salmon (Oncorhynchus kisutch) supports an important farming production in parallel with capture delivery, giving rise to products of great economic importance in many countries.

Comparison of Allergenic Properties of Salmon (Oncorhynchus nerka) between Landlocked and Anadromous Species

open access: yesAllergology International, 2009
Background: Salmon is one of the most widely consumed seafoods in Japan and many other countries around the world. Due to the confirmed cases of salmon-induced allergy, the food sanitation law in Japan stipulates salmon as one of the specific food items ...

Two Types of cDNAs Encoding Proopiomelanocortin of Sockeye Salmon, Oncorhynchus nerka [PDF]

open access: yesZoological Science, 1996
To investigate regulatory mechanisms of proopiomelanocortin (POMC) gene expression in sockeye salmon, we have isolated and characterized cDNAs encoding two types of sockeye salmon POMC, which are referred to as ssPOMC-A and -B. Two types of PCR products were amplified from total RNA of sockeye salmon pituitaries by use of rainbow trout sequences.

The Effects of Nutrient Additions on Kokanee in Dworshak Reservoir, Idaho

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT We investigated the effects of whole reservoir nitrogen (N) addition on kokanee growth in Dworshak Reservoir, Idaho. We hypothesized that N addition would improve the growth of kokanee (Oncorhynchus nerka) at a given level of abundance by increasing the availability of Daphnia, an important food source.
