The relationship between smolt and postsmolt growth for Atlantic salmon (Salmo salar) in the Gulf of St. Lawrence [PDF]

, 2006
The interaction of ocean climate and growth conditions during the postsmolt phase is emerging as the primary hypothesis to explain patterns of adult recruitment for individual stocks and stock complexes of Atlantic salmon (Salmo salar). Friedland et al. (

Evolution of age and length at maturation of Alaskan salmon under size-selective harvest [PDF]

, 2013
Spatial and temporal trends and variation in life-history traits, including age and length at maturation, can be influenced by environmental and anthropogenic processes, including size-selective exploitation.

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.

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

, 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).

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 ...

Production of single-domain magnetite throughout life by sockeye salmon, Oncorhynchus nerka [PDF]

, 1988
Although single-domain particles of biogenic magnetite have been found in different species of pelagic fishes, nothing is known about when it is synthesized, or about whether the time during life when it is produced is correlated with the development of

Frequency responses of age-structured populations: Pacific salmon as an example

, 2010
Increasing evidence of the effects of changing climate on physical ocean conditions and long-term changes in fish populations adds to the need to understand the effects of stochastic forcing on marine populations.

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

Zoological 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.

Aerobic scope is sustained through a heatwave in juvenile Atlantic salmon (Salmo salar)

Journal of Fish Biology, EarlyView.
Abstract Aquatic ectotherms are vulnerable to heatwave‐induced physiological stress, which arises from increased energy demands and reduced dissolved oxygen content in warmer waters. Understanding thermal physiology is critical for predicting how commercially and ecologically important populations could be affected by the increasing risk of rising ...

Maintenance of Genetic Diversity in Natural Spawning of Captively-Reared Endangered Sockeye Salmon, Oncorhynchus nerka

Diversity, 2014
Captive propagation of Pacific salmon is routine, but few captive breeding programs have been conducted to successfully re-establish extirpated wild populations.
