Recommendations for dietary level of micro-minerals and vitamin D3 to Atlantic salmon (Salmo salar) parr and post-smolt when fed low fish meal diets [PDF]

PeerJ, 2019
Atlantic salmon (Salmo salar) feeds have changed drastically in their composition from being predominantly marine-based to plant-based. This has altered the dietary supply and availability of micro-nutrients to Atlantic salmon.

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

Canadian 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.

The influence of the freshwater environment and the biological characteristics of Atlantic salmon smolts on their subsequent marine survival

, 2012
Atlantic salmon have declined markedly in the past 20-30 years throughout their range. Much of the focus for this decline has been on increased mortality during the marine phase of the life cycle.

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]

PeerJ, 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)

Frontiers 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.

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.

Knowledge 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 ...

Relationship between sockeye smolt-to-adult survival and smolt abundance.

, 2014
Legend: Aggregate Babine (i.e., wild and enhanced) sockeye smolt-to-adult survival as a function of smolt abundance (the total number of out-migrating sockeye smolts in a given year between 1962–2002).

Variation in skin barrier function throughout smoltification in Atlantic salmon (Salmo salar)

Frontiers in Physiology
IntroductionSmoltification involves distinct morphological, physiological and behavioral changes in Atlantic salmon, yet skin barrier function has not been functionally assessed throughout this transition.MethodWe measured electrophysiological parameters

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

Aquaculture 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.

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 ...
