L’UTILISATION DE L’HUILE DE CLOU DE GIROFLE COMME ANESTHÉSIQUE POUR LES SMOLTS DE SAUMON ATLANTIQUE (SALMO SALAR L.) ET COMPARAISON DE SES EFFETS AVEC CEUX DU 2-PHENOXYETHANOL.

Knowledge and Management of Aquatic Ecosystems, 2002
Cette étude révèle que l’huile de clou de girofle est un bon anesthésique pour les smolts de saumon atlantique, plus performant que le 2-phénoxyéthanol car agissant pour de plus faibles concentrations.

Smolt age and size of Atlantic salmon Salmo salar L. and sea trout Salmo trutta L. in a Norwegian river

Fauna Norvegica, 1984
This paper gives data on smolt age and length of Atlantic salmon and sea trout in the Orkla river in the period 1979 - 1981. The smolt age of the salmon was significantly higher in 1979 (4.1 years) as opposed to 3.4 and 3.3 years in 1980 and 1981 ...

ON EFFECT OF THE SIZE OF SOCKEYE SALMON ONCORHYNCHUS NERKA SMOLTS ON TIME OF THE SCALE SCLERITE FORMING DURING IMPLEMENTING OF THEIR COMPENSATORY GROWTH IN THE YEAR OF MIGRATION TO THE SEA FROM LAKE AZABACHYE (KAMCHATKA RIVER BASIN)

Известия ТИНРО, 2018
The Kamchatka River basin is the reproduction area for the secondary large Asian stock of sockeye salmon, one of the most valuable species of pacific salmons. Several major local stocks and groups of minor stocks occupy the basin, the main of them are: i)

Plasma proteome profiling of freshwater and seawater life stages of rainbow trout (Oncorhynchus mykiss).

PLoS ONE, 2020
The sea-run phenotype of rainbow trout (Oncorhynchus mykiss), like other anadromous salmonids, present a juvenile stage fully adapted to life in freshwater known as parr.

Histidine nutrition and genotype affect cataract development in Atlantic salmon, Salmo salar L. [PDF]

, 2005
The aim of this study was to investigate effects of dietary levels of histidine (His) and iron (Fe) on cataract development in two strains of Atlantic salmon monitored through parr-smolt transformation.

Atlantic Salmon (Salmo salar) Transfer to Seawater by Gradual Salinity Changes Exhibited an Increase in The Intestinal Microbial Abundance and Richness

Microorganisms, 2022
The host’s physiological history and environment determine the microbiome structure. In that sense, the strategy used for the salmon transfer to seawater after parr-smolt transformation may influence the Atlantic salmon’s intestinal microbiota. Therefore,

Effect of Photoperiod and Transfer Time on Atlantic Salmon Smolt Quality and Growth in Freshwater and Seawater Aquaculture Systems

Fishes, 2023
Smoltification is a key process in Atlantic salmon aquaculture, given it prepares the fish for a successful transit from fresh to seawater. However, industry players have not yet reached a consensus on the best protocols to produce high-quality smolts ...

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.
