Can Atlantic salmon smolt twice? Endocrine and biochemical changes during smolting

open access: yesCanadian Journal of Fisheries and Aquatic Sciences, 2000
Smolting is characterized by morphological and physiological changes, some of which are reversible if fish remain in freshwater. Whether fish that smolt in the first year will repeat physiological changes associated with smolting a second time is not known.

Antioxidant nutrition in Atlantic salmon (Salmo salar) parr and post-smolt, fed diets with high inclusion of plant ingredients and graded levels of micronutrients and selected amino acids [PDF]

open access: yesPeerJ, 2016
The shift from marine to plant-based ingredients in fish feeds affects the dietary concentrations and bioavailability of micronutrients, amino acids and lipids and consequently warrants a re-evaluation of dietary nutrient recommendations.

Upcycling of carbon, nitrogen, and phosphorus from aquaculture sludge using the polychaete Hediste diversicolor (OF Müller, 1776) (Annelida: Nereididae)

open access: yesFrontiers in Sustainable Food Systems, 2023
IntroductionFocusing on circular bioeconomy and finding solutions for managing finite and scarce resources such as phosphorus are issues that need to be addressed across sectors to attain food security.

No Evidence of the Vertical Transmission of Non-Virulent Infectious Salmon Anaemia Virus (ISAV-HPR0) in Farmed Atlantic Salmon

open access: yesViruses, 2021
The nonvirulent infectious salmon anaemia virus (ISAV-HPR0) is the putative progenitor for virulent-ISAV, and a potential risk factor for the development of infectious salmon anaemia (ISA).

Efficacité d'un exutoire de dévalaison et d'une barrière acoustique pour les smolts de saumon atlantique (Salmo salar L.) à l'aménagement hydroélectrique de St. Cricq sur le gave d'Ossau.

open access: yesKnowledge and Management of Aquatic Ecosystems, 1999
Une expérimentation a été conduite en 1996 au niveau de l'aménagement hydroélectrique de St. Cricq (gave d'Ossau) dans le but de tester deux dispositifs de dévalaison destinés à éviter le passage dans les turbines des smolts de saumon atlantique (Salmo ...

Dietary effects on biomarkers of growth, stress, and welfare of diploid and triploid Atlantic salmon (Salmo salar) during parr-smolt transformation

open access: yesAquaculture Reports, 2022
Triploidy is induced in Atlantic salmon (Salmo salar) to produce sterile fish for genetic containment and to hinder early sexual maturation in farmed fish, but it can have unwanted negative effects on growth, health, and welfare.

Experiences in Bayesian Inference in Baltic Salmon Management [PDF]

open access: yes, 2014
We review a success story regarding Bayesian inference in fisheries management in the Baltic Sea. The management of salmon fisheries is currently based on the results of a complex Bayesian population dynamic model, and managers and stakeholders use the ...

Energetic Status Modulates Facultative Migration in Brown Trout (Salmo trutta) Differentially by Age and Spatial Scale

open access: yesFrontiers in Ecology and Evolution, 2019
Fish display a remarkable diversity in juvenile migration strategies and behavior. Intra-species variation in migration can be considerable, and understanding the driving force of such variation is important for effective management and conservation of ...

Impacts of a Changing Ecosystem on the Feeding and Feeding Conditions for Atlantic Salmon During the First Months at Sea

open access: yesFrontiers in Marine Science, 2022
During the last decades, many wild Atlantic salmon populations have declined dramatically. One hypothesis for an observed reduction in salmon marine growth and survival is reduced abundance of prey.

Potential Impact of Climate Change on Salmonid Smolt Ecology

open access: yesFishes, 2023
The migratory life history of anadromous salmonids requires successful migration between nursery, feeding, and spawning habitats. Smolting is the major transformation anadromous salmonids undergo before migration to feeding areas.
