The effects of environmental stress on the physiology of growth in rainbow trout, Salmo gairderi Richardson [PDF]

, 1988
There is little doubt that both mammalian and teleost growth hormones can accelerate growth and increase food conversion efficiency in all commonly-reared species of salmonid fish.

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.

Differences in early developmental rate and yolk conversion efficiency in offspring of trout with alternative life histories [PDF]

, 2016
Partial migration, in which some individuals of a population migrate while other individuals remain resident, is generally associated with ontogenetic shifts to better feeding areas or as a response to environmental instability, but its underlying ...

Consequences of a sockeye salmon shortage for the brown bear in the basin of Lake Kurilskoe, Southern Kamchatka

Nature Conservation Research: Заповедная наука, 2021
We studied the behavioural ecology of Ursus arctos (hereinafter – brown bear or bear) in the basin of Lake Kurilskoe (Kamchatka Peninsula) in the summer and autumn of 2017–2018. The aim of this study was a comparative assessment of the behaviour of brown

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 ...

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

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.

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.

Interaction between watershed features and climate forcing affects habitat profitability for juvenile salmon

Ecosphere, 2020
Opportunities for growth and survival of aquatic organisms are spatially and temporally variable as habitat conditions across watersheds respond to interacting climatic, geomorphic, and hydrologic conditions.

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.
